“…Feed supplementation with jitirana and mororó hays, and cactus pear did not improve performance and carcass traits of goats raised on caatinga pasture. Carvalho Júnior et al (11) obtained similar results when studied the effect of supplementation on the carcass traits of F1 Boer × non-descript breed goats (with 120 days of age and average weight of 15.52 kg) finished on native pasture. The same result was registered by Silva et al (26) , who studied the effects of supplementation levels (0.0; 0.4; 0.8 and 1.2% BW) on the carcass traits of crossbred goats finished in the caatinga.…”

The objective of this study was to evaluate the carcass traits of crossbred F1 goats (Boer x non-descript breed) finished on thinned caatinga pasture enriched with signal grass (Urochloa trichopus Stapf.), and receiving supplementation. Twenty-four crossbred F1 goats with 27.00 ± 3.32 kg body weight were used. The supplement was designed to meet the nutritional requirements and animals receiving the highest supplementation level could gain 150g per day. For data analysis, a completely randomized design was adopted, with four treatments (supplementation levels of 0.0%; 0.5%; 1.0% and 1.5% body weight) and six replications (animals). Data were subjected to analysis of variance and regression. Supplementation resulted in an increasing linear effect for slaughter weight, hot carcass weight, cold carcass weight, empty body weight, hot carcass yield and cold carcass yield; and a quadratic effect for biological yield. Weight loss by cooling was not influenced by supplementation. For the results of subjective evaluations, only conformation was influenced by supplementation (P<0.05). For morphometry, a positive linear effect of supplementation was found for thorax perimeter, croup perimeter, croup width, thorax width. The level of supplementation caused a positive linear effect on the weight of most non-edible carcass components, and there was no influence of supplementation on most variables for yield. It can be concluded that increasing levels of supplementation up to 1.5% body weight for F1 goats (Boer x non-descript breed) kept on caatinga pasture results in higher carcass weight and yield.

Resumo Objetivou-se avaliar as características de carcaça de caprinos mestiços F1 (Bôer x sem padrão de raça definida) terminados em pastagem de caatinga raleada e enriquecida com capim corrente (Urochloa trichopus Stapf.), submetidos a suplementação. Foram utilizados 24 caprinos mestiços com peso vivo 27,00 ± 3,32 kg. O suplemento foi elaborado de modo a atender as exigências nutricionais para que os animais do maior nível de suplementação obtivessem um ganho de 150 g diário. Para a análise dos dados foi adotado o delineamento inteiramente casualizado, com quatro tratamentos (níveis de suplementação de 0,0%; 0,5%; 1,0% e 1,5% do peso vivo) e seis repetições (animais). Os dados foram submetidos a análises de variância e de regressão. Observou-se que a suplementação proporcionou efeito linear crescente para o peso ao abate, peso de carcaça quente, peso de carcaça fria, peso de corpo vazio, rendimento de carcaça quente e rendimento de carcaça fria; efeito quadrático para o rendimento biológico. A perda de peso por resfriamento não sofreu influência da suplementação. Para os resultados das avaliações subjetivas apenas a conformação sofreu influência da suplementação (P<0,05). Para a morfometria observou-se efeito linear positivo da suplementação para o perímetro do tórax, perímetro da garupa, largura da garupa, largura do tórax. O nível de suplementação proporcionou efeito linear e positivo sobre o peso da maioria dos não componentes comestíveis da carcaça, sendo que para o rendimento não foi observado influência da suplementação para a maioria das variáveis. Conclui-se que o uso crescente de suplementação até o nível de 1,5% do peso vivo para caprinos F1 (Boer x sem padrão de raça definida) mantidos em pastagem de caatinga resulta em maiores pesos e rendimentos de carcaças.

Carcass traits and meat quality of lambs fed with cactus (Opuntia fícus-indica Mill) silage and subjected to an intermittent water supply

et al. 2020

The present study aimed to evaluate the effect of cactus silage and an intermittent water supply for lambs on carcass traits and meat quality. Thirty-six crossbreed lambs with an initial average weight of 19.8 ± 2.1 kg and average age of 6 months were randomly assigned to a 3 × 3 factorial design comprising three addition ratios of cactus silage to the diet (0, 21, and 42% based on dry matter) and three water supply intervals (0, 24, and 48 h) with four replicates. There was no interaction (P > 0.05) between the cactus silage ratio and intermittent water supply for any of the evaluated variables, with the exception of the yield of the half carcass commercial cuts. There was no significant effect of intermittent water supply (P > 0.05) on the carcass characteristics or meat quality. The addition of forage cactus silage as a substitute for Tifton hay affected the morphometric measurements (P < 0.05) and carcass compactness index (P < 0.05). The addition of 42% cactus silage to the diet increased (P < 0.05) the rib eye area (13.98 cm 2). The addition of cactus silage as a substitute for Tifton hay positively affected (P < 0.05) the carcass weight of commercial cuts of the lambs. To the physical and chemical parameters of the Longissimus lumborum, the addition of 42% cactus silage to the diet reduced the color meat parameters (P < 0.05) and pH 0 and 24h , cooking losses, and shear force were not affected (P > 0.05). The addition of forage cactus silage to the lambs' diet affected (P < 0.05) the composition of some saturated fatty acids in the meat. A water supply interval of up to 48 h does not influence carcass characteristics and meat quality. Therefore, the use of cactus silage can be recommended in situations of water scarcity without harming the production or meat quality of crossbreed lambs.
