“…Thus, the higher the weight of the prime cuts and the lower the weight of good cuts, the higher the commercial value of the carcass. In the regional composition, maximum commercial yield of prime cuts is sought (Rodrigues et al, 2008). In the present experiment, this value was, on average, above 50%, confirming the biological variability of the use of forage cactus meal as an alternative to ground corn.…”

-The objective of this study was to evaluate the effect of the replacement of a ground corn diet by a forage cactus meal diet on the carcass characteristics and body components of Santa Inês lambs finished in feedlot. This study was carried out at Estação Experimental de Pendência, belonging to Empresa de Pesquisa Agropecuária da Paraíba S.A. (EMEPA-PB).Forty Santa Inês male lambs in feedlot were used in the experiment. Treatments were randomly assigned to the animals according to a completely randomized design, with four treatments, which consisted of growing replacement levels of ground corn by forage cactus meal: 0, 33, 66 and 100% of substitution and ten replications (lambs). Animals were slaughtered, and the following characteristics were evaluated: body weight, empty body weight, hot carcass weight, cold carcass weight, non-carcass components (NCC), hot carcass yield, cold carcass yield, biological yield, revenue of non components of carcass, revenues of non-carcass components, relative weight and relative value of the commercial cuts, viscera and organs' yield. Averages were submitted to analysis of variance and regression analyses at a 5% level of probability. The replacement levels of ground corn by forage cactus meal had no influence on biological yield, revenue of the non components of carcass, relative weight and relative value of the prime and choice cuts or on the relative weight of viscera and organs. The replacement of ground corn by forage cactus meal, on the ration given to Santa Ines lambs in feedlot does not impact the biological yield, relative weight and relative value of prime and choice cuts or the relative weight of viscera and other organs.

“…Os rendimentos de carcaça quente obtidos com as dietas com soja grão e gordura protegida foram semelhantes aos observados por Rodrigues et al (2008) A medida da AOL realizada no músculo longissimus tem indicado relação direta com o total de músculos da carcaça, enquanto a espessura de gordura subcutânea, com o total de gordura na carcaça e indiretamente com a quantidade de músculos, uma vez que, quanto maior o acúmulo de gordura, menor a proporção de músculos (Lawrie, 2005). Cunha et al (2008) observaram efeito linear decrescente (P<0,01) para a AOL; com decréscimo de 0,063 cm 2 para cada unidade de aumento no nível de caroço de algodão na dieta.…”

“…Os resultados das perdas no cozimento (PCOZ) observados foram semelhantes aos obtidos por Rodrigues et al (2008), ao avaliaremm a carne de cordeiros Santa Inês, terminados em confinamento. Esses autores observaram valores de PCOZ de cerca de 20% e relataram que esta variável pode estar associada à quantidade de gordura na carcaça.…”

“…Rodrigues et al (2008b), avaliando esses parâmetros na carcaça de cordeiros alimentados com ração contendo 68,4% de PCD, verificaram valores de 32,5 kg; 49,8%; 2,9%, 12,7 cm 2 e 1,5 mm, respectivamente. Caparra et al (2007) a PCQ = peso de carcaça quente; PCF = peso de carcaça resfriada; RCQ = rendimento de carcaça quente; RCF = rendimento de carcaça fria; PR = perda por resfriamento; AOL = área de olho-de-lombo; EG = espessura de gordura.…”

Desempenho, características da carcaça, digestibilidade aparente dos nutrientes, metabolismo de nitrogênio e parâmetros ruminais de cordeiros alimentados com rações contendo polpa cítrica úmida semidespectinada e/ou polpa cítrica desidratada Performance, carcass characteristics, apparent digestibility of nutrients, nitrogen metabolism and ruminal measures of lambs fed diets containing wet low pectin citrus pulp and/or dried citrus pulp ABSTRACT -The objective of this study was to determine the effects of partial replacement of dried citrus pulp (DCP)by wet low pectin citrus pulp (WLPCP), wet low pectin citrus pulp silage (WLPCPS) or wet low pectin citrus pulp silage with sodium benzoate (WLPCPS+B) on performance and carcass characteristics, apparent digestibility of nutrients, ruminal measures, and nitrogen metabolism of lambs. In the performance trial, 64 Santa Inês ram lambs were fed 95% concentrate and 5% sugarcane bagasse diets during 56 days. The experimental design was a randomized complete block (RCB). The control diet contained 69.5% DCP, while in the other treatments fresh or ensiled WLPCP replaced DCP by 30% on a DM basis.There were no differences in DMI, ADG or carcass characteristics. However, feed efficiency was greater for lambs fed WLPCP compared with lambs fed DCP. In the digestibility trial, 16 Santa Inês ram lambs, canulated in the rumen, were assigned to a RCB design. Animals were fed diets containing 85% of concentrate and 15% of sugarcane bagasse. The control diet contained 75.3% DCP. A portion (30%) of the DCP DM was replaced by WLPCP, WLPCPS or WLPCPS+B. There was no difference in DM, organic matter or crude protein apparent digestibilities, except for neutral detergent fiber digestibility. Additionally, ruminal ammonia concentration was higher in diets containing DCP compared with WLPCPS and WLPCPS+B. Nevertheless, no effects of treatments were seen on the other ruminal measures. Fresh or ensiled WLPCP can partially replace DCP in rations with high level of concentrate for feedlot lambs.
