Desempenho Produtivo e qualidade da carcaça de cordeiro avaliados em dois sistemas alimentares

Abstract: Ao início do período experimental e a cada 20 dias, as seguintes mensurações foram realizadas: peso corporal, altura do anterior, altura do posterior, comprimento corporal, perímetro torácico e condição corporal. Ainda obteve-se a estrutura corporal (frame size index) por meio da fórmula [FSI = (altura do anterior + altura do posterior + comprimento corporal + peso corporal)/4], e a compacidade (compacidade = peso corporal/comprimento corporal). Ao término do período experimental foram abatidos oito animais, q… Show more

“…Lambs fed alfalfa had lower values, with an inferior development than the others. The value of 14.50 cm found in our experiment for leg depth in both suckling lamb systems (pasture and confinement) was higher than the average values found by Lima et al (2013) and Motta et al (2016), with values of 12.22 and 11.76 cm, respectively. The values of 24.00 and 23.66 cm for chest depth found for suckling lambs on pasture and in confinement, respectively, are similar to those found by Fernandes et al (2008).…”

“…Finishing system CV (%) Weaned lambs fed concentrate also presented lower values in relation to carcass conformation, with an average value of 2.53, differing significantly (P<0.05) from suckling lambs in confinement and weaned lambs fed roughage, which presented averages of 3.23 and 3.19, respectively. The average value of carcass conformation of our experiment was higher when compared to that found by Motta et al (2016) and similar to that found by Carvalho et al (2017), who found an average value of 3.03 when working with confined lambs submitted to different inclusion levels of wet brewery residue as a roughage food. When studying the carcass characteristics of Santa Ines sheep of two biotypes, Lira et al (2017) found an average value of 2.57 for carcass conformation, similar to that of suckling lambs on pasture and weaned lambs fed concentrate of our study.…”

“…Contudo, em condições adversas, este fato é prejudicial à ovelha, ocasiona maior desgaste e pode até comprometer seu desempenho reprodutivo futuro, agravando-se à medida em que o nível nutricional torna-se não ideal (18) . O campo nativo sob condições adequadas de manejo pode proporcionar desempenhos satisfatórios à desmama de cordeiros, sem afetar a estrutura corporal das mães (19) . Apesar de as ovelhas grandes serem mais pesadas ao parto e ao desmame, as mesmas não foram mais eficientes nas avaliações produtivas quando comparadas com as de estrutura médias.…”

“…proporcionando elevados desempenhos. Os abatidos aos 180 dias, agora desmamados, passaram a se alimentar de azevém em estágio avançado de desenvolvimento, de pastagem nativa e de pastagem cultivada de milheto, configurando uma dieta de menor qualidade (MOTTA et al, 2016;COSTA et al, 2018). Como resultado, embora sob condições climáticas favoráveis ( Tabela 1) apresentaram GMD de somente 0,104 kg entre o desmame (90 dias) e o abate.…”
