“…The average intake of neutral detergent fiber, in kg/day and g/kg of BW was 0.503 kg/day and 19.6 g/kg of BW, respectively. Similar results to those obtained in this study were reported by Camurça et al (2002), who observed mean values of 515.04 kg/day and 18.2 g/kg of BW, respectively.…”

“…The higher intake of crude protein for mesquite pod meal, sorghum meal and wheat meal treatments is due to the intake of concentrate supplement, supplied at 10 g/kg of BW, with an average of 227.0 g/kg of CP. The mean value for the treatment with concentrate supplementation was 0.100 kg/day; this result was lower than that obtained by Camurça et al (2002), who evaluated the intake of sheep fed urochloa Grass supplemented with concentrate at 10 g/kg of BW and obtained an intake of crude protein of 0.151 kg/day. These higher values of crude protein intake are explained by the high crude protein content (CP) of the concentrate used by the authors (335.0 g/kg of CP).…”

“…This difference can be explained by the quality of the forages with respect to crude protein (CP) (108.2 g/kg vs. 66.4 g/kg of CP) and neutral detergent fiber (NDF) (737.4 g/kg vs. 764.2 g/kg of NDF). Camurça et al (2002), in a study with sheep supplemented with 10 g/kg of BW with corn and soybean meal-based concentrate, found for the dry matter intake, values of 0.943 kg/day, 32.4 g/kg of BW and 75.11 g/kg 0.75 , similarly to treatments with concentrate supplementation. With regard to forage intake (Urochloa grass), they found values of 0.660 kg/day, 22.8 g/kg of BW and 52.58 g/kg 0.75 , which are close to that in this study for all treatments.…”

-This study was conducted with the objective of evaluating the effect of concentrate supplementation, formulated with different ingredients (Mesquite pod meal, sorghum meal or wheat meal and mineral supplementation) on performance, intake and digestibility of nutrients in Santa Inês lambs grazing on urochloa grass during the dry season. Twentyfour uncastrated weaned Santa Inês sheep, with average body weight (BW) 20±2 kg with an average of 120 days of age were used in the assay. The experiment lasted 75 days. The animals grazing deferred Urochloa grass (Urochloa mosambicensis (Hack) Daudy) were distributed into four treatments consisting of mineral supplementation provided ad libitum and concentrated supplements containing mesquite pod meal, sorghum meal or wheat meal, supplied 10 g /kg BW on dry matter basis. The intakes of dry matter (DM) and crude protein (CP) were affected by the intake of concentrate supplement, regardless of the ingredients used in the supplements, compared with the mineral supplementation treatment, since the consumption of forage was reduced in 30% with mesquite pod meal supplement, and neutral detergent fiber (NDF) intake was not affected in relation to treatments. The digestibility of DM and CP were higher for treatments with supplements, and NDF digestibility did not differ between treatments. A significant difference was observed in the values of average daily gain for the treatments with concentrate supplementation compared with the one of mineral supplementation. The supplementation with concentrate in grazing enables improvement of performance, intake and digestibility of nutrients regardless of the ingredient used in the supplement.

“…Esses resultados foram semelhantes aos obtidos por Camurça et al (2002), que observaram valores médios de 515,04 g/ animal/dia, 1,82%PV e 41,97g/UTM, trabalhando Tabela 5 -Consumo de proteína bruta de ovinos alimentados com dieta contendo diferentes níveis de farelo de castanha de caju na ração concentrada e equações de regressão Tabela 4 -Consumo de matéria seca de ovinos alimentados com dieta contendo diferentes níveis de farelo de castanha de caju (FCC) na ração concentrada e equações de regressão (1994) justifica-se, pois espera-se que dietas contendo maiores níveis de farelo de castanha apresentem maior densidade energética. Dessa forma, as dietas contendo menores níveis de farelo de castanha seriam mais consumidas, na tentativa de se atingir a ingestão ótima de energia.…”

“…Estes dados confirmam os resultados obtidos por Camurça et al (2002), que não observaram diferenças no ganho de peso de ovinos Santa Inês machos e fêmeas. Esse autor argumenta que a provável explicação para esse fato seria a limitação no fornecimento de nutrientes pelas dietas fornecidas.…”

RESUMO -O trabalho foi conduzido com o objetivo de avaliar a utilização de concentrados contendo farelo de castanha de caju (FCC) na alimentação de ovinos mantidos em confinamento. Foram testados quatro tipos de concentrados isoprotéicos contendo 0, 12, 24 e 36% de FCC, tendo o concentrado participado com 30% da matéria seca (MS) da dieta total. Foram utilizados 32 ovinos sem raça definida (SRD), machos e fêmeas, em esquema fatorial 4 x 2 (quatro níveis de inclusão de FCC e dois sexos) e quatro repetições. Foram avaliados ganho de peso e conversão alimentar, bem como os consumos de matéria seca (CMS), proteína bruta (CPB), extrato etéreo (CEE) e fibra em detergente neutro (CFDN). Estas variáveis foram analisadas conforme o consumo em g/animal/dia, % do peso vivo (PV) e g/UTM (PV 0,75 ), tendo sido feita a análise de variância com teste de médias e estudo de regressão. Foram observadas diferenças no CMS, CPB e CEE de animais alimentados com dietas com 0 e 36% de FCC, com tendência de diminuição dos consumos de MS, PB e FDN, à medida que se aumentou o FCC na dieta. O consumo de EE elevou-se com a adição FCC às dietas. O ganho de peso e a conversão alimentar foram semelhantes para as quatro dietas fornecidas. Portanto, o FCC deve ser utilizado com um nível de inclusão de 24% do concentrado, não ultrapassando 6% de lipídios na dieta total.Palavras-chave: confinamento, farelo de castanha de caju, lipídios, ovinos Levels of Cashew Nuts Meal in Diets for Feedlot SheepABSTRACT -A study was conducted to evaluate the use of cashew nuts meal (CNM) in diets for sheep, raised in feedlot. Thirty two crossbred animals received concentrates with the same amount of crude protein, but four different levels of CNM (0, 12, 24 and 36%). A factorial 4 x 2 was used, with four levels of CNM and 2 sexes, with four repetitions. Daily weight gain and feed conversion as well as intake of dry matter (DM), crude protein (CP), ether extract (EE), neutral detergent fiber(NDF) and ashes were determined by analysis of variance, Duncan statistical test and regression analysis. Intake was estimated as g/animal/day, percentage of body weight (%BW) and g/BW 0.75 . There were differences in intake of DM, CP and EE when animals were fed concentrates with 0 and 36% of CNM. Also, intake of DM, CP and NDF tended to decrease as the levels of CNM increased in the diet. EE intake increased according to the different CNM levels. The type of diet did not significantly affect either weight gain or feed conversion. Therefore, cashew nut meal can be included up to 24% in the concentrate, but the total diets should not have more than 6% of fat. IntroduçãoA ovinocultura é atividade tradicional do Nordeste brasileiro, sendo caracterizada por rebanhos de animais sem raça definida (SRD), com baixo potencial genético e criados de forma extensiva, apresentando, dessa forma, baixos índices de produtividade. A alimentação dos animais é um dos fatores que mais influencia a manutenção deste quadro na região, que sofre longos períodos de estiagem e falta de alimentos.O con...
