“…Therefore, it can be inferred that in all carcasses, regardless of the level of replacement, there was similar capacity for development and tissue growth, which agrees with the findings of Faria et al (2011). The similarity observed in these variables is a result of the standardization of the carcasses and the relationship between weight at time of slaughter and carcass parameters.…”

It was hypothesized that maize steep liquor, which is high in crude protein, could replace soybean meal in supplementation strategies in lamb production systems. Therefore, the effects of replacing soybean meal with maize steep liquor at 0%, 33%, 66% and 100% on a dry matter (DM) basis on growth performance, nutrient digestibility and carcass characteristics were assessed in feedlot lambs. Thirty-two Santa Inês intact male lambs, with an average initial weight of 21.0 ± 2.3 kg, were assigned to a completely randomized block design with four treatments and eight replicates. Intake of DM, organic matter, ether extract, neutral detergent fibre and total digestible nutrients were not affected by the diets. However, the intake of crude protein (CP) was reduced by 0.2 g/day for each 1% increase in the replacement level of soybean meal with maize steep liquor. Replacement of soybean meal with maize steep liquor in the diets did not affect the apparent digestibility of nutrients with the exception of CP, which decreased by 14.1 g/kg DM for each 1% increase in the replacement level of soybean meal. Similar trends were observed for average daily gain, hot carcass weight, cold carcass weight, hot carcass yield and cold carcass yield. From these results, soybean meal could be replaced by up to 100% with maize steep liquor in finishing diets for feedlot lambs. ______________________________________________________________________________________

“…According to Van Soest (1994), the growth of the reticulum-rumen can be influenced by several factors, including diet, especially in terms of NDF content. Faria et al (2011), using different ways of processing cassava peel in sheep feed, did not observe changes in the weight of the rumen, reticulum, omasum or abomasum. There was no effect (P>0.05) of the diets on the weight of the "Panelada", yields of viscera, byproducts, "Buchada" and yours relations with BWS and EBW (Table 8).…”

The objective was to evaluate the effect of the substitution (0, 33, 66 and 100%) of corn by cassava wastewater dregs on carcass characteristics and non-carcass components of crossbred Santa Inês lambs. Forty male sheep, uncastrated with an average initial body weight of 20 ± 1.87 kg and five months of age, were used. These were housed in individual pens in a randomized block design with four treatments and ten repetitions and slaughtered after 70 days of confinement. Quadratic effect (P<0.05) was observed for the empty body weight (EBW), hot carcass weight (HCW) and cold carcass weight (CCW) and carcass compactness index (CCI), with maximum points of 36.14, 19.45, 20.20 and 0.31 kg cm -1 for the replacement level of corn for cassava wastewater dregs, 50.0, 53.84, 54.04 and 45.45% respectively. There was also an effect (P<0.05) on the weights of the rumen and "Buchada", with maximum points of 0.909 and 6.25 kg per replacement level, 49.11 and 51.29% respectively. As for retail cuts, only the efficiency of the leg was altered (P<0.05), having a linear increase while the other variables were not affected. Cassava wastewater dregs can be used in full as an alternative food in the diet of feedlot lambs without harming the main carcass characteristics and non-carcass components.

ResumoObjetivou-se avaliar o efeito da substituição (0, 33, 66 e 100%) do milho pela borra de manipueira sobre as características de carcaça e componentes não-carcaça de cordeiros mestiços Santa Inês. Foram utilizados quarenta ovinos machos não castrados, com peso corporal inicial médio de 20 ± 1,87 kg e cinco meses de idade. Estes foram confinados em baias individuais, em delineamento em blocos ao acaso, com quatro tratamentos e dez repetições, e abatidos após 70 dias de confinamento. Efeito quadrático (p<0,05) foi observado para o peso do corpo vazio (PCV), peso de carcaça quente (PCQ) e fria (PCF) e o índice de compacidade da carcaça (ICC), as mesmas apresentaram pontos de máxima de 36,14; 19,45; 20,20 e 0,31kg cm -1 ao nível de substituição do milho pela borra de manipueira de 50,0; 53,84; 54,04 e 45,45%, respectivamente. Também houve efeito (p<0,05) sobre os pesos do rúmen e da buchada, com ponto de máxima de 0,909 e 6,25 kg ao nível de substituição de 49,11 e 51,29%, respectivamente. Quanto aos cortes comerciais, apenas o rendimento da perna foi alterado (p<0,05) apresentando efeito linear crescente. Enquanto as demais variáveis não foram afetadas. A borra de manipueira pode ser utilizada de forma integral como alternativa alimentar na dieta de cordeiros em confinamento, sem prejudicar as principais características da carcaça e os componentes não-carcaça.

“…Os estudos relacionados aos cordeiros da raça Santa Inês também encontram-se voltados para aspectos zootécnicos, como o desempenho (SOUZA et al, 2011b;FERNANDES et al, 2011;CASTRO et al, 2012), qualidade física e sensorial da carne , características de carcaça (PEREIRA et al, 2010;FARIA et al, 2011) morfologia muscular (SANTELLO et al, 2010a;SANTELLO et al, 2010b), qualidade da carne (MORENO et al, 2011;ALBUQUERQUE et al, 2014) e comportamento ingestivo (OLIVEIRA et al, 2013;NEGRI et al, 2013).…”
