Desenvolvimento corporal e relação entre biometria e peso de cordeiros lactantes da raça Santa Inês criados na Amazônia

Abstract: RESUMOObjetivou-se com este trabalho descrever as medidas biométricas de cordeiros lactantes da raça Santa Inês criados em condições amazônicas; estabelecer relação entre a idade e as medidas corporais; bem como correlacionar essas medidas biométricas com o peso corporal. Utilizaram-se 75 animais criados em sistema semi-intensivo, submetidos a mensurações do peso corporal (PC), comprimento corporal (CC), altura do anterior (AA) e do posterior (AP), perímetro torácico (PT), largura da garupa (LG) e do peito (LP… Show more

“…Several studies found a high and positive correlation between body measurements and body weight at slaughter (Fernandes Junior et al, 2015;Silva et al, 2016;Souza et al, 2014). In these studies, the body measurement with the highest correlation with body weight at slaughter was the chest circumference, and consequently this measurement was the one that best predicted body weight at slaughter.…”

“…According to Marques et al (2008), CW is one of the biometric measures that can be used to predict live weight at slaughter in Santa Inês animals. However, Souza et al (2014) showed that despite the high correlation of CW with the live weight of lambs, it is less predictive of the body weight of these animals. However, in this study, the body weight (Table 2) of the animals and the increase in chest width showed a positive linear growth; that is, as the chest width increased, there was an increase in body weight.…”

“…Among the tools used to measure the productivity of small ruminants, body biometry (as a way of assessing the growth of animals), which, when analysed along with other zootechnical indexes, constitutes an important database for the individual evaluation of animals and to determine the evolution of the productive system (SOUZA et al, 2014). In addition, these in vivo biometric measurements have a high correlation with carcass measurements and, together with other zootechnical indexes, can help to predict some productive characteristics, such as weight, carcass yield and conformation, the proportion of muscles and adipose tissue, as well as the yield of cuts, orienting producers to the best time to slaughter their animals (MORENO et al, 2010;PINHEIRO et al, 2007).…”

“…The similar yield of meat cuts observed in all RIG groups reflects the similar SBW and carcass sizes of animals in different groups. Previous works provided evidence of moderate to high correlation among BW, carcass yield, and yield of meat cuts in sheep (Pinheiro and Jorge, 2010;Souza et al, 2014). According to Fernandes et al (2011), when animals of the same breed have equivalent body conformation, their carcass weight, carcass yield, and relative weight of meat cuts are also similar.…”
