ABSTRACT Diversifying pastures with forage legumes may reduce nitrogen fertilization due to biological N fixation. This study aimed to quantify forage accumulation rate and macronutrients extraction and to identify the best intercropping combination between butterfly pea (Clitoria ternatea) – a legume, and three warm-season forage grasses of different growth habits (signalgrass – Urochloa decumbunes, Guinea grass - Mega thyrsus maximus, and bermudagrass Cynodon dactylon). Treatments consisted of mixes of perennial herbaceous legume, butterfly pea (twining stem), with grasses, signalgrass (decumbent stem) and Guinea grass (erect stem), and bermudagrass (stoloniferous/rhizomatous). The experiment was arranged in a randomized complete block design, with three treatments and three replications. There was interaction between the intercropping combinations and cutting cycles for forage accumulation rate (FAR) and N, P, K, Ca, Mg, and S uptake. Phosphorus and K uptake was reduced from the second cycle onwards, except for the signalgrass-butterfly pea intercropping, whose reduction was only from the third cycle. Conversely, the signalgrass-butterfly pea and bermudagrass-butterfly pea intercropping did not differ from each other in relation to total N concentration in soil, but the signalgrass-butterfly pea intercropping showed total N concentration in soil higher than that of Guinea grass-butterfly pea intercropping. A higher predominance of the N-NH4+ form was observed in the soil. Grass-legume intercropping increased the demand for nutrients, which makes it indispensable to verify the export of macronutrients to know when to supply these nutrients removed from the soil solution. fixation Clitoria ternatea legume warmseason warm season decumbunes maximus dactylon. dactylon . dactylon) twining stem, stem , decumbent erect stoloniferous/rhizomatous. stoloniferousrhizomatous stoloniferous/rhizomatous stoloniferous rhizomatous (stoloniferous/rhizomatous) design replications FAR (FAR P Ca Mg onwards signalgrassbutterfly Conversely bermudagrassbutterfly grassbutterfly NNH4+ NNH4 NNH NH4+ NH4 NH N-NH4 Grasslegume Grass solution (stoloniferous/rhizomatous N-NH

ABSTRACT. The aim of this study was to evaluate the influence of completely replacing soybean meal (SM) with castor cake detoxified (DCC) with two alkaline products on the nitrogen balance and hepatic and renal function in goat kids. Goat kids of two breeds, Saanen and Anglo Nubian, with an initial body weight of 16.2 ± 0.67 kg, and confined during the growth phase, were used. The treatments consisted of three diets: one based on SM and the other two based on castor cake detoxified with Ca(OH)2 or NaOH. Twenty-four goats kids were distributed in a completely randomized design using a 3 x 2 factorial scheme (diet x breed) with four replicates per combination. The experimental period lasted for 270 days. Consumed nitrogen, fecal nitrogen, urinary nitrogen, retained nitrogen, and nitrogen balance were influenced (p < 0.05) by diets. There was significant effect of diets (p < 0.05) on creatinine, direct bilirubin, urea, alanine aminotransferase, aspartate aminotransferase and gamma-glutamyltransferase blood levels, however without any negative changes involving renal or hepatic dysfunction. Inclusion of castor cake in the diet of goats kids in confinement is an attractive option, considering that goats kids use does not cause hepatic and renal alterations, suggesting that SM can be completely replaced. NaOH DCC stands in the substitution of soybean meal, because in spite of decreasing the consumption of nitrogen provides the same retention of soybean meal.

ABSTRACT. The cashew pseudo fruit can be used to animal feeding in tropical and subtropical countries as Brazil, Ivory Coast and Vietnam. Thus, our objective was to evaluate the intake, digestibility of nutrients and nitrogen balance of dehydrated cashew apple by-product to sheep. The experiment was carried out with 24 sheep in a completely randomized design with the treatments distributed in a 4 x 2 factorial scheme to test the inclusion (11, 21, 28 and 33% dry matter basis) and the grinding sizes (3 and 19 mm diameter) of dehydrated cashew apple by-product. To grinding sizes there was no effect to intake and digestibility, suggesting the use of dehydrated cashew apple by-product either finely or coarsely milled. The inclusion up to 33% of dehydrated cashew apple by-product inclusion did not affect voluntary intake and nitrogen balance. However, when including above 21%, there was a reduction of ether extract digestibility and more than 28% reduced dry matter and organic matter digestibility.

RESUMO Objetivou-se avaliar os parâmetros fisiológicos, as características produtivas, estruturais e composição química de Megathyrsus maximus (syn. Panicum maximum) cultivares BRS Massai e BRS Tamani submetidas à diferentes períodos de diferimento e momentos de utilização. Utilizou-se o delineamento de blocos completos casualizados, em esquema fatorial 2 x 2 x 3, sendo duas cultivares de gramíneas (capim-massai e capim-tamani), dois períodos de diferimento (período chuvoso e transição chuvoso-seco) e três tempos de vedação (40, 80 e 120 dias). Ambas as cultivares tiveram maior taxa de transpiração foliar quando utilizadas aos 40 dias de diferimento (0,63 μmol/m2/s). Observou-se que a cultivar BRS Massai apresentou a maior taxa fotossintética (1,10 μmol/m²/s), taxa de produção e acúmulo de forragem quando utilizada aos 40 dias de diferimento (P<0,05). Por outo lado, houve maior eficiência no uso da água durante o período de transição nos pastos vedados por 80 e 120 dias (64,60 e 62,30 kg de MS/ha/mm, respectivamente). Observou-se redução (P<0,05) dos nutrientes digestíveis totais (NDT) e proteína bruta (PB) com o aumento no tempo de vedação das pastagens. De modo geral o diferimento no período de transição possibilita a utilização da forragem sem maiores perdas produtivas e nutritivas até os 80 dias de vedação para a cultivar BRS Tamani e até os 40 dias para a BRS Massai.

ABSTRACT This study aimed to evaluate the physiological parameters, the productive characteristics, structural and chemical composition of Megathyrsus maximus (syn. Panicum maximum) cultivars BRS Massai and BRS Tamani submitted to different periods of deferment and moments of use. The experimental design was randomized complete block design in a factorial scheme 2 x 2 x 3, being two grass cultivars (Massai grass and Tamani grass), two deferment periods (rainy season and dry-rainy transition) and three sealing times (40, 80 and 120 days). Both cultivars had higher leaf transpiration rate when used for 40 days of deferment (0.63 μmol/m2/s). It was observed that the cultivar BRS Massai presented higher photosynthetic rate (P<0.05) to 40 days of deferment (1.10 μmol/m2/s), higher rate of production and forage accumulation when used for 40 days. On another side, there was a greater efficiency in the use of water during the period of transition in the pastures sealed for 80 and 120 days (64.60 and 62.30 kg DM/ha/mm, respectively). A reduction (P<0.05) of total digestible nutrients (TDN) and crude protein (CP) was observed with the increase in pasture sealing time. In general, the deferment in the transition period allows the use of forage without greater productive and nutrient losses up to 80 days of sealing for the cultivar BRS Tamani and up to 40 days for BRS Massai.

ABSTRACT. To evaluate the ingestive behavior of sheep confined and fed with substitution levels of soybean meal (SM) by detoxified castor cake (DCC). We adopted a completely randomized design, with four levels of substitution (0; 33; 67 and 100%) with five replicates (sheep). We estimated the percentages of total times of intake of feed, time of rumination, in ‘other activities’, in idle agreed and in idle sleeping, dividing the day into eight periods (5h00 to 8h00; 8h01 to 11h00; 11h01 to 14h00; 14h01 to 17h00; 17h01 to 20h00; 20h01 to 23h00; 23h01 to 2h00 and 2h01 to 5h00). No interaction was observed between levels of substitution of the SM by DCC and period of the day to go. However, the isolated effect period of the day, there is more time to go from 8h00 to 11h00. The time rumination was not influenced by the levels of substitution of the SM by DCC. As for the variable other activities, the level of 67% DCC was superior to that of 100%. Regarding the variables idle agreed and idle sleeping, were not observed effects of substitution levels of SM by DCC. The DCC provides no changes in the behavior of the sheep, but the period of the day exerts influence on the behavioral pattern of such animals.

RESUMO Objetivou-se avaliar os parâmetros fisiológicos, as características produtivas, estruturais e composição química da Urochloa Brizantha cultivares BRS Paiaguás e BRS Piatã submetidos a dois períodos de diferimento e três momentos de utilização. Utilizou-se o delineamento de blocos completos casualizados, em esquema fatorial 2 x 2 x 3, sendo duas cultivares de gramíneas (capim-paiaguás e capim- piatã), dois períodos de diferimento (período chuvoso e transição chuvoso-seco) e três tempos de vedação (40, 80 e 120 dias). Observou-se que, dentro do período chuvoso, as gramíneas tiveram maior taxa de transpiração foliar quando utilizadas aos 40 dias de diferimento (1,66 µmol m2/s). Neste mesmo período, a condutância estomática foi detectada somente nas gramíneas utilizadas com menor tempo de vedação, apresentando média de 0,07 µmol m2/s. Em contrapartida, no período de transição, a concentração diminuiu para 0,02 µmol m2/s. De forma geral, a cultivar BRS Paiaguás apresentou menor teor de FDN. O menor tempo de vedação proporcionou maior produção de biomassa de forragem total durante o período da chuva, cerca de 2,78 vezes mais forragem que o mesmo pasto diferido durante o período de transição. De modo geral, ambos os períodos de diferimento e tempos de vedação causam efeitos nas características estruturais da pastagem, sendo que o diferimento no período de transição por um tempo de 40 e 80 dias pode ser uma estratégia para manutenção dos animais em períodos críticos.

ABSTRACT This study aimed to evaluate the physiological parameters, the productive characteristics, structural and chemical composition of Urochloa Brizantha cultivars BRS and BRS Piatã submitted to two deferment periods and three using times. The experimental design was randomized complete block design in a factorial scheme 2 x 2 x 3, being two grass cultivars (Paiaguás grass and Piatã grass), two deferment periods (rainy season and dry-rainy transition) and three sealing times (40, 80 and 120 days). It was observed that, in the rainy season, the grasses had higher leaf transpiration rate when used for 40 days of deferment (1.66 µmol m2/s). During the rainy season, the Stomatal conductance was detected only in the grasses used with shorter seal, with an average of 0.07 µmol m2/s. In contrast, in the period of transition, the concentration decreased to 0.02 µmol m2/s. In a general way, the BRS Paiaguás presented lower content of NDF. The shorter cycle provided greater biomass production of total forage during the period of rain, approximately 2.78 times more than the same pasture grass deferred during the transition period. Generally, the periods of deferment and moments of use cause effects on structural characteristics of pasture, being that the period of deferment of the transition period and used for 40 and 80 days may be a strategy for keeping animals in critical periods.

RESUMO Avaliou-se a influência de quatro níveis de substituição (0; 33; 67 e 100%) do farelo de soja (FS) pela torta de mamona destoxificada (TMD) em rações sobre o consumo, digestibilidade dos nutrientes e balanço de nitrogênio em ovinos mestiços, machos, não castrados em delineamento em blocos completos ao acaso com quatro tratamentos e cinco repetições. Observou-se efeito linear decrescente dos níveis de substituição do FS pela TMD sobre o consumo de matéria seca (MS), matéria orgânica (MO), proteína bruta (PB), carboidratos totais (CT), carboidratos não fibrosos (CNF), nutrientes digestíveis totais (NDT), digestibilidade da MS, MO e CT com reduções respectivas de 2,04; 1,70; 0,35; 1,56; 1,89 e 1,67 g dia-1 e 0,34; 0,53 e 0,51 g kg-1 de MS, para cada 1% de substituição do FS pela TMD. O CMS e FDNcp expressos em %PC e g kg-0,75 apresentaram resposta quadrática com valor máximo de 3,85 e 1,73%PC e 95,15 e 42,47 g kg-0,75 com 25,00; 65,00; 20,75 e 61,50% de substituição do FS pela TMD, respectivamente. Houve aumento linear no consumo de fibra em detergente ácido e digestibilidade do extrato etéreo. O balanço de nitrogênio não foi influenciado pela substituição do FS pela TMD. A substituição do farelo de soja pela torta de mamona destoxificada por autoclavagem na ração de cordeiros altera o consumo e digestibilidade dos nutrientes sem influenciar o balanço de nitrogênio.

ABSTRACT The effect of substituting soybean meal (SM) with four levels (0, 33, 67 and 100%) of detoxified castor cake (DCC) on intake, nutrient digestibility and nitrogen balance was evaluated in uncastrated, male, crossbred sheep in a randomised complete block design with four treatments and five replications. There was a decreasing linear effect from the levels of substitution on dry matter (DM), organic matter (OM) and crude protein (CP) intake, total carbohydrates (TC), non-fibrous carbohydrates (NFC) and total digestible nutrients (TDN), and on DM, OM and TC digestibility, for reductions of 2.04, 1.70, 0.35, 1.56, 1.89 and 1.67 g dia-1 and 0.34, 0.53 and 0.51 g kg-1 DM respectively, for each 1% SM substituted with DCC. DMI and NDFap expressed, in %BW and g kg-0.75, showed a quadratic response, with a maximum value of 3.85 and 1.73%BW, and 95.15 and 42.47 g kg-0.75, for 25.00, 65.00, 20.75 and 61.50% SM substituted with DCC respectively. There was a linear increase in the intake of acid detergent fibre and in ether extract digestibility. The nitrogen balance was not affected by the substitution of SM with DCC. Substituting soybean meal with castor cake detoxified by autoclaving in lamb diets alters nutrient intake and digestibility without affecting the nitrogen balance.

ABSTRACT We aimed to evaluate the lactation curves, composition, and fatty acid profile of milk of lactating goats fed diets containing detoxified castor cake (DCC) by alkaline solutions during 150 days of lactation. Twenty-four Saanen and Anglo Nubian goats, approximately 17 months old (first lactation) and 43±2.97 kg body weight, were distributed in a completely randomized block design with eight replicates. Treatments consisted of three diets, one containing soybean meal (SM) and two others containing DCC, with calcium hydroxide [Ca(OH)2] and sodium hydroxide (NaOH). The lactation curves showed greater persistence of lactation in Saanen goats. There were significant effects of diets on the profile of some fatty acids present in the milk. We observed that the NaOH DCC diet led to an increase in desirable fatty acid content. Both Ca(OH)2 and NaOH DCC diets led to decreased milk production during the lactation period; however, the NaOH DCC diet led to high productive efficiency. Furthermore, NaOH DCC did not negatively affect the desirable fatty acid content, unlike Ca(OH)2 DCC. Diets formulated with detoxified castor decrease the production of milk from goats during lactation phase. It should be emphasized that milk produced by goats fed DCC diets does not contain unwanted waste.

ABSTRACT The objective was to evaluate the intake, digestibility, nitrogen balance, and metabolic profile of lactating goats fed diets containing detoxified castor cake (DCC) by alkaline solutions during 150 days of lactation. Twenty-four Saanen and Anglo Nubian goats, approximately 17 months old (first lactation) and body weights of 43±2.97 kg, were distributed in a completely randomized block design with eight replicates. Treatments consisted of three diets, one containing soybean meal (SM) and two others containing DCC, with calcium hydroxide [Ca(OH)2] and sodium hydroxide (NaOH). The diets significantly influenced the intake of dry matter (DM), crude protein (CP), ether extract (EE), neutral detergent fiber (NDF), and total digestible nutrients (TDN). We observed a higher dry matter intake (DMI) in goats fed SM, similar to that of goats fed Ca(OH)2 DCC. Intake of nutrients followed the same trend as DMI. There was no significant effect of diets on digestibility of DM, CP, EE, and NDF; however, we observed a significant effect of diets on the levels of nitrogen intake (NI) and urinary nitrogen (UN). The goats fed SM consumed a larger quantity of nitrogen, but all had the same nitrogen balance, indicating that goats fed DCC were more efficient. The diets did not influence renal and hepatic parameters. Inclusion of castor cake in the diet of goats in confinement is an attractive option, considering that goats fed DCC present lower feed conversion, and its use does not cause hepatic and renal alterations, suggesting that SM can be completely replaced.

RESUMO Objetivou-se avaliar a inclusão de soro de queijo bovino (SQB) na dieta para ovinos sobre o comportamento ingestivo, os parâmetros ruminais e sanguíneos. Vinte ovinos mestiços, machos, não castrados, com 25 kg de peso corporal foram distribuídos em quatro dietas: dieta controle (composta por milho, farelo de soja e silagem de pasto nativo) e as dietas teste (dieta controle + inclusão de SQB em níveis crescentes 1,6; 2,7 e 4,0% na MS), em um delineamento inteiramente ao acaso com quatro tratamentos e cinco repetições. A comparação de médias foi realizada pelo teste Tukey e foram testadas as correlações de Pearson entre as variáveis. Também foi feita a análise de regressão para os dados provenientes da coleta de líquido ruminal e de sangue. As avaliações de comportamento foram feitas em um intervalo de 24 horas em medições realizadas a cada cinco minutos. A inclusão de SQB na dieta não comprometeu o pH ruminal, mas promoveu a queda nos tempos de ruminação e de alimentação, ocasionando também menor número de bolos ruminais e menor número de mastigações merícicas. A menor concentração de nitrogênio amoniacal e proteínas totais foram encontradas nos ovinos que receberam a dieta com 4% de inclusão de SQB. Entretanto, esses valores ficaram dentro do padrão estabelecido para crescimento microbiano. O SQB é uma potencial alternativa proteica na alimentação de ovinos por não interferir no consumo de nutrientes, nos parâmetros ruminais e sanguíneos, e favorecer o balanço positivo de nitrogênio.

ABSTRACT The objective of this study was to evaluate the inclusion of cow cheese whey (CCW) in the diet for lambs on the ingestive behavior, ruminal and blood parameters. Twenty crossbred, male, non-castrated lambs with 25 kg body weight were assigned to four treatments: control diet (composed of corn, soybean meal and native pasture silage) and test diets (control diet + inclusion of CCW in increasing levels of 1.6, 2.7 and 4.0% in DM), in a completely randomized design with four treatments and five replications. Means were compared by Tukey’s test, and the strength of association between variables was tested by Pearson’s correlation. Regression analysis was also performed for data from the collection of ruminal fluid and blood. Behavioral assessments were made at a 24-hour interval in measurements taken every five minutes. The inclusion of CCW in the diet did not impair ruminal pH, but promoted a decrease in rumination and feeding times, also causing a lower number of cuds and a lower number of cud chews. The lowest concentration of ammonia nitrogen and total protein were found in lambs receiving the diet with 4% CCW. However, these values were within the range recommended for microbial growth. CCW is a potential protein alternative in lambs feed as it does not interfere with nutrient intake, ruminal and blood parameters, and favors a positive nitrogen balance.

Resumo: O objetivo deste trabalho foi avaliar o efeito da substituição do farelo de soja (FS) pela torta de mamona detoxificada (TMD), contendo diferentes soluções alcalinas, nos parâmetros nutricionais de cabritas (Capra aegagrus hircus) Saanen e Anglonubiana. Os tratamentos consistiram de três dietas: uma à base de milho e FS; e duas com TMD por Ca(OH)2 ou NaOH. Os dados de consumo e digestibilidade foram analisados em duas fases, de acordo com as curvas de crescimento das cabritas, que mostraram: crescimento acelerado linear (fase I, de 60 a 298 dias de vida) e redução na intensidade do crescimento corporal (fase II, de 299 a 345 dias). Durante a fase I, as cabritas alimentadas com TMD por NaOH apresentaram menor consumo de matéria seca (MS) e nutrientes. Durante a fase II, houve efeito das dietas sobre a ingestão de nutrientes, com exceção de extrato etéreo (EE), nutrientes digestíveis totais e energia metabolizável. Observou-se efeito da dieta na digestibilidade da MS, da proteína bruta, do EE e da fibra em detergente neutro, principalmente nas cabritas que consumiram as dietas com TMD. Embora menos consumidas, as dietas formuladas com TMD não afetam negativamente o desempenho nutricional das cabritas em ambas as fases de crescimento, uma vez que resultam em maior eficiência alimentar.

Abstract: The objective of this work was to evaluate the effect of replacing soybean meal (SM) by detoxified castor bean cake (DCC), containing different alkaline solutions, on the nutritional parameters of Saanen and Anglo-Nubian female goat (Capra aegagrus hircus) kids. The treatments consisted of three diets: one based on corn and SM; and two with DCC with Ca(OH)2 or NaOH. Intake and digestibility data were analyzed in two phases according to the growth curves of the goats, which showed: a linear accelerated growth (phase I, from 60 to 298 days of life) and a reduction in the intensity of body growth (phase II, from 299 to 345 days). During phase I, the goat kids fed DCC with NaOH showed a lower intake of dry matter (DM) and nutrients. During phase II, there was significant effect of diets on the intake of nutrients, with the exception of ether extract (EE), total digestible nutrients, and metabolizable energy (ME). A diet effect was observed on the digestibility of DM, crude protein, EE, and neutral detergent fiber, mainly for goat kids fed diets with DCC. Despite their lower intake, the diets formulated with DCC do not negatively affect the nutritional performance of female goats kids in both growth phases, since they result in a greater feed efficiency.

ABSTRACT This study aimed to evaluate the performance and ingestive behavior of growing goats grazing on Tanzania guinea grass and fed diets containing 40% carnauba or tucum fruits. Twenty-one male castrated goats were distributed into three groups, one exclusively on pasture and the other two on pasture and fed diet supplemented at the level of 1.5% body weight (BW) in a completely randomized design. The intake of the supplements was obtained by difference between the amount supplied and the leftovers, with weighing performed every seven days, while pasture intake was determined using titanium dioxide (TiO2) as external indicator. Ingestive behavior was evaluated for three days. The supplement containing carnauba fruit resulted in a greater intake of neutral detergent fiber (0.137 kg NDF/day), with a reduction of 8.61% in the pasture dry matter (DM) intake of goats. Associated with the intake of pasture nutrients, the tucum fruit diet met the protein (0.103 kg CP/day) and energetic (0.547 kg TDN/day) requirements of goats with intake set at 0.124 kg CP/day and 0.572 kg TDN/day, with higher weight gain (0.111 kg/day) and larger loin eye area (12.76 cm2). The supplementation with fruits influenced the grazing behavior of goats, increasing the idle time by 1 h in relation to animals not supplemented. The supplementation of growing goats grazing on Tanzania guinea grass pasture with a diet containing 40% tucum fruit, in the proportion of 1.5% BW, did not meet the nutritional requirements for gain of 150 g/day; however, it met requirements for maintenance and average gain of 111 g/day. Energy supplementation reduces the grazing time of goats; thus, it is necessary to consider the level and formulation of supplements, with the possibility of increasing the stocking rate and productivity per unit area.

RESUMO Objetivou-se estudar o efeito de diferentes tratamentos térmicos, tempos e procedimentos na degradação ruminal de grãos de soja crus e tostados e sua ação na digestão intestinal da proteína não degradada no rúmen (PNDR) pelo método dos três estágios. Para a degradação ruminal in situ foram pesados cinco gramas de matéria natural em sacos de náilon incubados durante 2; 4; 8; 16; 24 e 48 horas. No tempo zero foi efetuado o mesmo procedimento, excetuando a incubação ruminal. Os resíduos de cada tratamento formaram uma amostra composta para determinar a matéria seca (MS) e proteína bruta (PB). Para a digestibilidade intestinal realizou-se a incubação in situ por 16 horas, usando a técnica dos três estágios. A degradabilidade efetiva da MS com taxa de passagem de 5%/hora para a soja crua (SC) foi de 71,94% e tostada entre 52,23% a 68,78%. Após 16 horas de incubação a PNDR variou de 32,12 a 67,72% e a digestibilidade intestinal de 73,21% a 86,02%. A menor degradação da MS e PB foi da soja tostada a 145°C durante um minuto com steeping (STC1). A digestibilidade intestinal in vitro dos grãos crus foi superior e diferiu dos tostados, exceto a soja tostada a 115°C durante quatro minutos com steeping. A menor degradação proteica foi obtida da STC1de 67,72% da PNDR,52,33% a mais do que à SC. A tostagem dos grãos de soja a 145°C(STC1)contribuiu para uma menor degradabilidade ruminal da proteína bruta.

SUMMARY This study analyse ruminal degradation the technique of the nylon bags of dry matter (DM) and crude protein (CP) and the intestinal digestibility of rumen undegraded protein (RUP) by the method of the three stages of raw and roasted soybeans at different temperatures with and without The in situ ruminal degradation were weighed five grams of natural matter in nylon bags incubated 2; 4;8; 16; 24 and 48 hours. Zero time was made the same procedure, except ruminal incubation. The residue of treatment formed a composite sample to determine the DM and CP. The intestinal digestibility was in situ incubation for 16 hours, using the technique of the three stages. The degradability of DM at a passage rate of 5 % / hour, for raw soybean (RS), was 71.94 % and roasted between 52.23 % and 68.78 %. After 16 hours of incubation(RUP) ranged from 32.12 to 67.72% and the intestinal digestibility of 73.21% to 86.02 %. The lowest degradation of DM and CP was in the roasted soybeans at 145ºC for one minute with steeping (STC1). The in vitro intestinal digestibility of raw grains was higher and differed from the toasted, except for the ones toasted at 115 ºC for four minutes with steeping. For STC1, was obtained the lowest protein degradation of 67.72 % RUP, which 52.33 %, more when compare to RS. The toast of soybeans at 145 ºC (STC1) contributed to a lower ruminal degradability of crude protein.

Avaliou-se o desempenho produtivo e características quantitativas e qualitativas de carcaça e dos não-componentes de carcaça de cordeiros SPRD (Sem Padrão Racial Definido) cruzados com as raças Santa Inês (SI) e Somalis Brasileira (SB) terminados em confinamento. Foram utilizados 16 cordeiros desmamados, machos, não castrados, com peso inicial 19,7±2,0kg e três meses de idade. Adotou-se o delineamento em blocos ao acaso, com blocos representados pelo peso inicial de cada grupo genético (½ SPRD x ½ SI e ½ SPRD x ½ SB), com oito animais por grupo. Os ovinos ½ SPRD x ½ SI apresentaram maior ganho de peso diário e total, comprimento e perímetro de pernil, comprimento interno da carcaça, peso e rendimento do corte serrote, peso e rendimento dos não-componentes da carcaça (pulmão e traqueia, fígado, rins, cabeça e patas). Os cordeiros ½ SPRD x ½ SB apresentaram maiores valores para escore de condição corporal inicial e final, espessura de gordura subcutânea, grau de acabamento, pH inicial e final. Assim, cordeiros mestiços ½ SPRD x ½ SI constituem uma alternativa promissora para o estabelecimento de sistemas produtivos mais eficientes, considerando a superioridade em ganho de peso e as características da carcaça relacionadas às medidas morfométricas, ao corte cárneo serrote e aos não-componentes da carcaça em relação aos animais ½ SPRD x ½ SB. No entanto, os cordeiros os cordeiros ½ SPRD x ½ SB apresentam superioridade quanto aos aspectos conservação da carcaça e nos casos de mercados com preferência por carcaça com maior teor de gordura.

We evaluated the growth performance and quantitative and qualitative characteristics of carcass and non-carcass components of crossbred lambs meat (½ undefined breed - SPRD x ½ Santa Inês - SI and ½ SPRD x ½ Somalis Brasileira - SB) finished in feedlot. We used 16 lambs weaned males, intact, with an initial weight of 19.7 ± 2.0 kg and about three months old. We adopted the design of randomized blocks, with blocks represented by the initial weight ranges for each genetic group evaluated (½ SPRD x ½ SI and ½ SPRD x ½ SB), with eight replicates in each group. Sheep ½ SPRD x ½ SI had higher average daily weight gain, total weight gain, length and head ham, carcass internal length, weight and yield of the hindquarter, weights and performance of non-carcass components (lung and trachea, liver, kidney, head and feet). ½ SPRD x ½ SB showed higher values for body condition scores initial and final fat thickness, degree of finish, initial pH and final. In this study, crossbred ½ SPRD x ½ SI lambs is a promising alternative to obtaining of production systems more efficient considering the superiority of weight gain and carcass characteristics related to morphometric measurements, cut meat diet hacksaw and non-carcass components in the ½ SPRD x ½ SB animals. However, SPRD ½ x ½ SB lambs feature superiority as the conservation aspects of carcass and in the case of markets with preference for carcass with higher fat content.
