Two experiments were conducted in order to assess the nutritional value of hay maniçoba (FM) compared with alfalfa hay (FA) as an ingredient in the diet of growing rabbits-finish. In experiment 1 were determined digestibilities of dry matter (DMD), crude protein (CPD), ether extract (DEE) and digestible energy (DE) was analyzed. 14 rabbits were used in growth, delivered in a completely randomized design with seven replications. FM presented at natural matter, 67.40% of DMS, 35.05% of BDP, 11.87% of DEE and 709 kcal DE / kg. In experiment 2, we used 56 rabbits (28 castrated males and 28 females) to evaluate the growth performance parameters, and carcass and meat composition. We evaluated increasing levels of replacement of the FA PB by PB FM at 0, 25, 50 and 75%. The experimental design was a completely randomized design with four treatments and seven replications, and housed two animals per experimental unit. The data were analyzed using the SAS program. Feed intake increased linearly as weight gain, feed conversion, live weight, hot carcass weights and cold and weight of the skin had a quadratic effect with maximum levels of substitution of crude protein (CP) of the FA protein of FM of respectively 58, 34.9, 54, 50, 50 and 50% respectively. The results of carcass composition showed that the percentage of CP increased to 31.6%, the ability to retain water up to 36.7%, while the fat percentage peaked in the substrate with 46.5% replacement of CP FA by PB FM. There was no effect of treatments on the levels of oleic fatty acids, lauric and palmitic acids in the muscle biceps femoris. Hay maniçoba contains 14.89% protein, 67.4% of DMS and 709 kcal DE / kg in MN. It is recommended to replace 58% of the FA PB by PB FM, with the additions of 14.33 kg of FM and 8.78 kg of FA/100 kg.

Communication devices are the social web 'actions in the library, making them closer to the users, to improve the interaction between them beyond physical environment of the library. Communication devices, as provided by libraries, can give greater visibility to the activities of the library, expanding the possibilities for dissemination and access to information. In this study a model for managing communication devices provided in the social web by university libraries based on information and knowledge management developed. He offered theoretical and methodological support to promote the effectiveness of mediation business information. It is characterized as a theoretical and empirical research, because, at first was supported in the literature to achieve the objective referred to the construction of indicators that support the proposal of a model for the management of communication devices social web provided by university libraries. Subsequently, the necessity of a rapprochement with the object of research and investigation can characterize it as an empirical reality. Both empirical and theoretical foundation will support research on how the management of information and knowledge can contribute to improving mediation business information communication devices of social web provided by university libraries. The model consists of six (6) central themes: strategic planning, organizational culture and information, infrastructure, information literacy, knowledge of the organization and evaluation. Since these issues was also possible to identify the components that integrate and their basis: management policy communication devices of the social web, participation, sharing, people, technology infrastructure, content, learning, needs and expectations of users and partners. It is considered that the mediation efforts of information and knowledge in the hands made by librarians in communication devices in the social web should be planned and the procedures for its implementation must be registered with the management policy, so level national in this process so as to realize standard in university libraries. The results show that university libraries to worship the manner of communication devices are contributing to improving mediation efforts of information and knowledge.

In this work, after the introduction of some concepts of Commutative Algebra, for instance dimension, minimal number of generators, and multiplicity, we prove the existence of a very special class of modules over Cohen-Macaulay rings, the so-called Ulrich modules. It is known that, if M is a maximal Cohen-Macaulay module over such ring, then (M) e(M). Our goal in this study is to prove the main cases where the equality (M) e(M) holds.

The information in the context in which society currently lives, known as the information society is becoming increasingly value, incurring importance in the daily lives of people as never before reached. In this context, there is the pursuit of Brazilian society in reaching a level of more mature democracy where citizens can be more involved in the State's actions, particularly in the monitoring of public politics and actions. Following a worldwide trend, Brazil seeks to structure a network that citizens can have greater access to government information through the obligation of public agencies and entities to create and maintain transparency portals, which has the task of seeking a closer relationship between the government and the population. In this sense, the research proposed the adequacy of the transparency portal of the Federal University of Paraíba to the Access to Information Act, to include all the information specified as mandatory by legal rules above, as well as inclusion of possible innovative initiatives taken by other institutional portals such, of to enable this important instrument for democracy can come to fulfill their important role in society.

The present research investigated the issue about the construction of knowledge from research in the training of mathematics teachers, having as main objective to analyze the training of undergraduates in Mathematics the participation in the practice of research as a methodology of teaching and learning, in a perspective of analysis and reflection from pivot points, elements and moments that limit or intensify the training of undergraduates for learning and teaching through research. We base the discussion on the Pimenta's knowledge and Perrenoud‟s Skills. We assume that knowledge mobilization is the fundamental requirement, and precedent, the development of any skills. The research focused on the conception of teachers, students, and the observance of the guidelines expressed from Teaching Project of the Course. The methodology is part of a Case Study, of qualitative approach and descriptive and exploratory nature. Data were analyzed from content Bardin (2009). For data collecting were used questionnaires , interviews with teachers who work in components that provide research and workshops for student records about their perceptions, concepts, skills, knowledge and competencies in relation to research. We had no expectation that graduates demonstrate dominate all phases of a research cycle, but identifying what the Course has been able to promote, in terms of training for this practice, along its development, but caused concern the framework we envision in the path of our investigation. The results showed the significant difficulties, and lack of undergraduates in the relationship and articulation among education, math and research, whose performance is worrying, by insufficient competence, to teach and to learn with and by research.

The hypothesis that oral supplementation with virgin coconut oil (Cocos nucifera L.) and exercise training would improve impaired baroreflex sensitivity (BRS) and reduce oxidative stress in spontaneously hypertensive rats (SHR) was tested. Furthermore, the effects caused by lauric acid (LA) on oxidative stress and cardiovascular parameters in spontaneously hypertensive rats (SHR) were evaluated. In the first stage of the study, SHR and Wistar Kyoto rats (WKY) were used and divided in five groups: WKY + saline (n = 8); SHR + saline (n = 8); SHR + coconut oil (2 mL·day -1, n = 8); SHR + training (n = 8); and SHR + training + coconut oil (n = 8). The swimming protocol under 4% body weight workload lasted 60 minutes. Mean arterial pressure (MAP) was recorded and BRS was tested using phenylephrine (8 μg.kg-1, iv) and sodium nitroprusside (25 μg·kg-1, iv). Oxidative stress was measured using dihydroethidium by microscopy fluorescence in tissue sections from heart and aorta samples. SHR + coconut oil, SHR + training and SHR + training + coconut oil groups presented lower MAP compared to SHR + saline (148 ± 6, 147 ± 7, 134 ± 8 vs. 175 ± 6 mmHg, P < 0.05). Coconut oil combined with exercise training improved BRS in SHR compared with SHR + saline group (-2.47 ± 0.3 vs. -1.39 ± 0.09 ± bpm-1·min-1·mmHg, p <0.05). SHR + saline group showed higher superoxide levels when compared with WKY + saline (774 ± 31 vs. 634 ± 19 arbitrary units (AU), respectively; p <0.05). SHR + training + coconut oil group presented a reduction in oxidative stress compared with SHR + saline in heart (622 ± 16 vs. 774 ± 31 AU, p <0.05). Moreover, coconut oil reduced oxidative stress in SHR compared with SHR + saline in aorta (454 ± 33 vs. 689 ± 29 AU, p <0.05). In the second stage of thestudy, LA reduced blood pressure at 3, 4, 8 and 10 mg/kg doses compared with vehicle (-41±9.4;-41±6;-51.7±8.1;-61±11 vs. -1,3±0.4 mmHg, n = 6). LA (10-8 to 3x10-3M) induced vasorelaxation in isolated cranial mesenteric artery rings in the presence or absence of functional endothelium (Emax=104,1 ± 2,8% e pD2= 4,1 ± 1,4; n=7 vs. Emax= 103,5 3,7 pD2 = 3,3 ± 0,5; n=8, respectively). LA (10-3 M) reduced superoxide levels similar to Tempol, a superoxide anion scavenger, compared to tissue containing only NADPH oxidase in the heart (18.1 ± 0.7; 9.5 ± 0.3 vs. 25.3 ± 0.4 UML / min / ug protein, respectively) and kidney (81.9 ± 2.8, 79 ± 1.3, 99 ± 4.3 vs. UML / min / ug protein, respectively). In conclusion, coconut oil combined with exercise training reduced oxidative stress and improved BRS in SHR. Those effects seem to be, at least in part, to its major component (Lauric acid).

Amburana cearensis (Allemão) B.C. Smith is a species native to the Northeast region of Brazil. It has been increasingly exploited for fine woodworking, perfumery and medicine. The experiments were conducted in Laboratory of Analysis of Seeds in the Center of Agricultural Sciences of the Federal University of Paraiba, Areia - PB and Laboratory of Image Analysis and Seed Analysis, Department of Plant Production, College of Agriculture "Luiz de Queiroz", University of São Paulo in Piracicaba - SP, aimed to obtain information about of vigor of seed A. cearensis. In the first experiment were tested the accelerated aging test and the seed were exposed at 42 °C during 0, 24, 48, 72 and 96 h. For the second experiment were tested the electrical conductivity test and potassium leachate test. The factors considered for the electrical conductivity test were: soaking time (4, 8, 12, 16, 20 e 24 h) and volume of deionized water (75 and 100 mL) at a constant temperature of 25 °C. The potassium leachate test was carried out with samples of 50 seeds placed in plastic cups containing 75 mL of distilled water at 25 °C and the evaluations were performed at intervals 4, 8, 12, 16, 20 e 24 h. In the third experiment, seeds were subjected to X-rays test for evaluation of internal damage in seeds. A period of 48 h of aging was suitable for use in future studies to evaluate seed vigor A. cearensis, it is possible to detect significant differences between lots. The electrical conductivity test and potassium leachate test possible the discrimination of lots os seeds, it is recommended combinations for electrical conductivity of 75 mL/12 h and 100 mL/8 h and the leaching soaking for 4 h. Radiographic analysis is an effective instrument for monitoring A. cearensis seeds lots quality, because it is non-destructive and allows the prediction of seedling performance and enables the maintenance of high-quality seed.

The catingueira [Poincianella pyramidalis (Tul.) L. P. Queiroz] is a tree species endemic to the Caatinga, quite explored for their potential timber, forage and pharmacological. Given the relevance of its importance, the research aimed to: (i) characterize the phenophases of P. pyramidalis, and its relation to the distribution of rainfall pulses; (ii) evaluate the physiological quality of seeds among individuals of P. pyramidalis through physiologic tests; (iii) determine the physiological maturation of the seeds and (iv) evaluate the potential for dry matter yield due to leaf abscission and its relation to the temporal distribution of rainfall. First 32 individuals of P. pyramidalis were selected, at Açude Farm, the city of Soledade-PB, as evaluation method using the percentage of intensity Fournier and activity index. To evaluate the variability between individuals and determination of the maturity, individuals catingueira fruits were collected and referred to the Laboratory of Seed Analysis (CCA/UFPB), for seed extraction and evaluation of physical and physiological variables. For quantification of dry matter due to leaf abscission catingueira, the work was conducted at the Experimental Station of São João do Cariri-PB, whinch where distributed under the canopy of 15 plants four collectors in the north-south and east-west direction. Thus, it was found that the the intensity and duration of phenophases in Poincianella pyramidalis depend on the amplitude and frequency of pulses of rainfall during the rainy season; the accelerated aging test, used in the traditional method, the period of 24 hours and at a temperature of 41 ºC shows the test vigor to be more efficient in evaluate the physiological potential of the seeds of P. pyramidalis; that conditions Soledade city-PB, for P. pyramidalis the point of physiological maturity occurs at 125 days after anthesis, when seeds reach maximum dry mass accumulation, and the harvest is reached between 130-135 d.a.a.; the rapid senescence and leaf fall of P. pyramidalis are due to interpulse precipitation and strong reduction of water availability in the soil; during the period of abscission, the incrise of contribution of leaves is highly dependent on the quantity of rainfall between years.

Sesame is an important oilseed crop and can be grown in tropical and subtropical regions around the world, such as the Northeast of Brazil. Its seeds have oil of high nutritional and protein content, used in the food industry and pharmaceutical, cosmetics and biofuel. However, in the Northeast there is irregularity rainfall and high evapotranspiration rates witch usually prejudice agricultural production and research development in order to select genotypes with characteristics of tolerance to these conditions. In this context, this study was carried out in order to evaluate growth, physiology and production of sesame genotypes under different rates of water replacement. The experiment was accomplished from September to December 2012 at the Experimental Station of Embrapa Algodão, Barbalha, CE, under field conditions. The randomized block design was adopted with treatments in a factorial (4 × 6), corresponding to four irrigation levels (40, 70, 100 and 130% of ETo) and six genotypes (G1=T3-EGSGO3; G2=T7-EGSGO7; G3=T5-EGSGO5; G4 =T2-EGSGO2; G5=T6-EGSGO6 and G6=T4-EGSG04) with three replications. During experiment were collected growth variables (leaf area, plant height and stem diameter), physiological and biochemical (relative water content, disruption of the cell membrane, content of photosynthetic pigments, carbohydrates and protein in leaves and root and peroxidase and catalase activity) and production (dry matter, oil content in seeds and productivity). Harvesting of Sesame was performed manually at 95 days after sowing. Higher growth and production occur using irrigation levels between 75 and 90% ETo. The content of pigments, chlorophyll b, and total carotenoids were enhanced with application of 80% ETo. The enzymatic activity of sesame cultivars was reduced in plants under drought stress by deficiency or by water excess. Maximum production potential of sesame is found with application of water levels in 75-90% of ETo.

The Caatinga Biome, even with the approach of recent years, is a region lacking of information that enables the understanding of how plants survive on stress conditions. Species that make up this biome, Myracrodruon urundeuva Fr. All. stand out for timber and medicinal properties, suffering for decades, intense and predatory exploitation, leading to compose the official IBAMA list of endangered flora. The aim of this work was to select individuals of M. urundeuva through viability and vigor tests and to evaluate the effect of water stress on seedling emergence of normal and morphoanatomy. For such individuals mastic were selected in three areas of Paraiba State, a municipality of the ray tracing and two in Boa Vista, in which diasporas were collected and sent to the Laboratory of Seed Analysis (LAS) UFPB, Areia-PB. Initially it has proceeded to determine the water content (TA) and the following assessments: Germination test (GT), emergency testing (ET), first count of germination and emergence (FCG and FCE), germination speed index and emergency speed index (GSI and ESI), length and dry weight of seedlings. The methodology for implementing saline accelerated aging was also determined. Thereafter individual diasporas (matrix) more vigorous of the three areas were subjected to water stress under conditions of retention capacity of the soil levels: 10, 15, 20, 25, 30, 35, 40, 45, 50, 55 and 60%. In this step we assessed the TA, TE, PCE, IVE, length and dry weight of roots and shoots of seedlings. To evaluate the morphoanatomy, diasporas mastic were subjected to the same continuous water conditions, described above, and a second temporary water condition. For this, they were initially sown in the soil retention capacity of 60%, then to simulate drought with stopping of watering until obtaining the capacities of 10, 15, 20, 25 and 30% retention. After subjected to continuous and temporary water conditions, morphoanatomical characteristics evaluated were: number of leaves, length and width of the primary, length, width and thickness of the central leaflet leaf; length, width and thickness of the cotyledon; number of stomata in the leaf and cotyledon length and diameter of the stem and root. In the initial evaluation of the seeds was observed that individuals of M. urundeuva germination and vigor have differentiated between the collection areas, as well as within the same area, demonstrating the adaptive plasticity of the species. The accelerated aging test in saline temperature of 41 °C during 24 hours is recommended due to the reduction of fungi, the eleventh individual, the stronger this test. When the eleventh individual diasporas were subjected to water stress, it was found that they have some degree of demand relative to water in the early periods of development. The structural and physiological assessments seedlings have adaptive characteristics for perpetuation over time and space in a natural environment. As for water regimes applied in the evaluation of morphoanatomical characteristics, treatments affected seedling development of mastic, and capabilities between 50 and 60% retention of the best treatments for the production of normal seedlings, for most variables.

In this work, we classify the solutions of the equation u + fue = 0 in R2 or R2 +. For this, we use basically the Moving Planes Method and and Moving Spheres Method. These methods ensure monotonicity and radial symmetry of the solution under certain conditions. The first method was used to study the case f 1 in R2 when RR2 eu is finite. The other was used to verify that the equation has no solution when f is a continuous function and radially symmetric, monotone in the region which has positive image and not constant. The latter method was also applied to the study of the problem ( u + eu = 0 em R2 +; @u @t = ceu=2 sobre @R2 +; for = 1; = 1 or = 0, modifying the conditions under the finiteness of RR2 + eu and R@R2 + eu=2. In most cases, when the equation has the solution, it was verified that the radially symmetrical. From this symmetry, we transform our Partial Differential Equations for Ordinary Differential Equations and we classify their solutions.

In this paper we discuss the problem of linear tting to experimental data using a method bio-inspired of optimization, i.e., it imitates the biological concepts attempt to nd optimal or suboptimal results. The method used is the genetic algorithm (GA), AG makes use of the theory of Darwinian evolution to nd the best route for the desired maximum point. Traditionally, the linear tting is made through the method of least squares. The method is e cient, but is di cult to justify the pre-calculus classes. Therefore, the alternative AG comes as a computationally exhaustive procedure, however easy justi cation for these classes. Thus, the purpose of this study is to compare the results of linear tting for some control scenarios using this methods and certify the quality of the adjustments obtained by the approximate method. At the end of the work it was found that the results are solid enough to justify the alternative method and the proposed use of this optimization process has the potential to spark interest in other areas of mathematics.

In this work, we present an introduction to the theory of C0-semigroup (and C0-group) of bounded linear operators, and we show that wave operator in RN is the in nitesimal generator of a C0-group of bounded linear operators in a appropriate Banach space.

Our purpose is to study the geometry of Riemannian immersions in certain semi- Riemannian manifolds. Initially, considering linearWeingarten hypersurfaces immersed in locally symmetric manifolds and, imposing suitable constraints on the scalar curvature, we guarantee that such a hypersurface is either totally umbilical or isometric to a isoparametric hypersurface with two distinct principal curvatures, one of them being simple. In higher codimension, we use a Simons type formula to obtain new characterizations of hyperbolic cylinders through the study of submanifolds having parallel normalized mean curvature vector field in a semi-Riemannian space form. Finally, we investigate the rigidity of complete spacelike hypersurfaces immersed in the steady state space via applications of some maximum principles.

In this paper, we study a special class of planar curves, convex curves of constant width. Moreover show basic examples of these curves, starting with the Reuleaux triangle that indeed is what has the smallest area when the constant width is de ned unlike the circle has the largest area and is also constant width. We generalize the construction of the Reuleaux triangle to regular polygons with odd numbers of sides that are called Reuleaux polygons. Finally we propose activities for the polygons of study in primary and secondary education as a suggestion for a school education, by reference to the polygons of Reuleaux in particular the Reuleaux triangle.

In this brief Brazilian Literature research we seek to detect and analyze the inter-ethnic relations and participation of black, either as subject or as a literary producer in the plans of poetry and novelistic fiction. The question of color prejudice is so inevitable, being emphasized more persistence and particularity in reading The Drums of St. Louis Joshua Montello, novel that, as we try to show is fairly representative in the context of regional and national slavery.

Umbu (Spondias tuberosa Arr Cam), umbu-caja (Spondias sp.) and cajarana do Sertão (Spondias sp.) are fruit tree species still in stage of domestication, which belong to the Anacardiaceae family, whose fruits are appreciated by the excellent sensorial quality, as well as an alternative source of income, due to the extractive exploitation of their fruit in the harvest season. The objective of this study was to evaluate the fruits of native genotypes of three species of the genus Spondias, umbu, umbu-caja and cajarana do Sertão (Spondias sp.) harvested in two maturity stages, from different areas of occurrence in the Paraiba and Rio Grande do Norte states, Brazilian Nortestern. After harvest, fruits were transported to the Laboratory of Biology and Technology Postharvest - CCA - UFPB, where it was carried out the physical and physicochemical evaluations. The contents of bioactive compounds, qualification of caratenoides, and total antioxidant activity (TAA) by ABTS and ORAC methods were conducted at the Center of Biotechnology and Fine Chemistry (CBQF) of the School of Biotechnology (ESB) at the Catholic University of Porto (UCP) - Porto, Portugal. Among the physical characteristics of the fruits stand out for high yield above 60% the umbu-caja and 80% the umbu. For the physicochemical characteristics, in umbu-caja it was observed values of SS of 11.86%, 1.05% AT, and the SS / TA ratio that was highlighted for the genotype G2, with the highest average 13.75. For umbu, the SS / TA ratio, the only the P11 genotype had an average below the minimum value (10.00) required by the Brazilian Standard of Identity and Quality (PIQ), standing out fruits of the genotypes P1 and P7 (Soledad - PB) and P17 (Juazeirinho - PB) with values higher than 16.00. Fruits from most genotypes (70.83%) are proper for fresh consumption, due to the acidity content below 1.0 g.100g-1 of citric acid, evidencing be an alternative to the fresh fruit market and for processing. The carotenoides were identified and quantified by HPLC and in these three species studied was found the following types: zeaxanthin, β- cryptoxanthin, and β-carotene, but this latter was not found in umbu-caja. The levels of total carotenoids in umbu-caja, and Spondias sp umbu Sertão were: 7.12, 2.46, and 1130.34 μg.100g-1, respectively. Zeaxanthin was the major constituent in these species evaluated, and the highest content was found in the full ripen cajarana do Sertão (Spondias sp) (463.67 μg.100g-1). The bioactive compounds directly responsible for antioxidant activity, in addition to the total carotenoids and their constituents were yellow flavonoids, in the cajarana do Sertão, and polyphenols, in umbu. These compounds provide a significant source of natural antioxidants to the diet of the population of the Semi-Arid. The ABTS method was adequate for quantification of the antioxidant activity in fruit of the genus Spondias.

The objective was to evaluate the influence of gestational stage, number of fetuses and food restriction on the intake, mineral balance, mineral composition of the maternal body, the pregnant uterus and mammary gland, as well as to estimate the retention and the requirement net and dietary minerals Ca, P, Mg, Na and K Moxotó goats in pregnancy. This study was conducted in the Experimental Station of São Joao do Cariri Eight females goats not pregnant were slaughtered for represent initial body composition. A group of females goats able to breeding was submitted to estrus synchronization, through hormonal protocols and those presenting estrus were mated in the breeding. Thirty days after the first mated, it was made a pregnant diagnostic and the checked the number of fetuses. After confirmed the gestation and determined the number of fetuses, the female goats were grouped according to gestation day (50, 100 and 140 days), type of gestation (single or double) and the level of food restriction (0%, 20% and 40% of restriction). It was used a completely randomized design in factorial arrangement 3 x 2 x 3. The female’s goats remained in individuals barns and were slaughtered in the different days of gestation. For the assessment of the intake and minerals balance, were used only the goats that were slaughtered in the 140 days of gestation. The metabolism digestibility was made in three different periods: from 35 to 50 days, from 85 to 100 and from 125 to 140 days. Were collected laboratory sampling separated of body in the goats, uterus, fetus and mammary gland for the laboratories analyses to determination of the minerals. The prediction model used for the minerals was MC = β0 × EBW β1, as MC = mineral content and EBW is empty body weight. It was observed that gestational age affected the intake and minerals balance of Moxoto goats in confinement and in lowest percentage the number of fetuses and level of restriction. The gestational age influenced the minerals concentration in the body maternal, pregnancy uterus, fetus and mammary gland, whereas that the number of fetuses influenced only the mineral composition of the pregnancy uterus and the fetuses of females goats. The level of food restriction not caused bigger changed in the variables and there are significant diferences in the net requirements of minerals for the moxoto female goats to 50,100 and 140 days of gestation, independent of the number of fetuses.

This study aimed to determine the different levels of feed restriction effect on performance, carcass, nitrogen balance and microbial protein synthesis in Red Sindhi cattle breed. The experiment was conducted at the Federal University of Viçosa, with 32 unneutered male bulls divided into four feed restriction levels (0, 15, 30 and 45%) in a completely randomized design. The dry matter intake reduction, promoted by increased restriction resulted in a decrease in the consumption of nutrients affecting the performance and some quantitative carcass traits except yield percentage (hot and cold) and loin eye area. Happened a linear decrease (P <0,05) in weight of retail cuts, however, was not observed (P> 0,05) change in the proportions of them in relation to the half carcass weight. Significant quadratic effect of restriction level on body weight end (WCF), empty body weight (EBW), total weight gain (TWG), average daily gain (ADG), gain of empty body weight (EBW) and efficiency feed (EA), from 0.5 to 7.0% restriction. Happened a linear increase (P <0,05) in the muscle proportion and linear decrease (P <0,05) in the proportion of carcass fat, with increasing level of restriction. The restriction promoted a reduction in nitrogen excretion to the environment, and increase efficiency in the use of recycled nitrogen by animals. Moderate restriction levels can be applied on the male Sindi termination without compromising performance, generating a 41% difference in the profit margin, compared to the level of 15% restriction to the group fed ad libitum.
