Composição tecidual da carcaça e perfil de ácidos graxos da carne de cordeiros terminados a pasto ou em confinamento

Abstract: RESUMO -Objetivou-se avaliar a composição tecidual do lombo e do pernil e o perfil de ácidos graxos da carne de cordeiros em quatro sistemas de terminação: 1) cordeiros desmamados com média de 40 dias e mantidos em pasto de azevém até o abate; 2) cordeiros com suas mães na mesma pastagem até o abate; 3) idem ao 2), porém com suplementação diária a 1% do PV em creep feeding; 4) cordeiros desmamados aos 40 dias e confinados, recebendo silagem de milho e concentrado ad libitum. O delineamento experimental foi int… Show more

“…The muscle/fat ratio found in the present experiment, however, was higher than the average 4.08 observed by these researchers. However, this ratio in the leg of animals from T23, T25, and T30 was close to the 5.71 found by Fernandes et al (2010) in feedlot-finished Suffolk lams slaughtered with 32 kg LW.…”

“…Thus, a high exposure to these fatty acids is associated with higher risk of cardiovascular disease, coronary heart disease and type 2 diabets. Fernandes et al (2010) studied lambs on pasture and confinement, and found no significant difference between both termination systems, with mean levels of 29.4% of palmitic acid (C16:0), while Costa et al (2012) has found an average of 25.08% in Santa Ines lambs fed diets with increasing levels of soybean hulls; both similar to this study with 23.07% for the same fatty acid.…”

“…Regarding the monounsaturated fatty acids identified in the meat fat, oleic acid was considered as the monounsaturated fatty acid with higher expression levels in ruminants. This study found a value of 1298.90 mg g -1 lipids for this fatty acid, representing 42.72% of the total, which is higher than that found by Fernandes et al (2010), who evaluated the lambs' termination in different termination systems, and found variations of 34.4% for feedlot animals. Oleic acid (18:1n-9) has beneficial effects in human's health.…”

“…O efeito da nutrição sobre a composição física da carcaça tem sido muito estudado e tem-se verificado que animais com melhor regime alimentar apresentam carcaças de melhor qualidade, visto que tiveram maior desenvolvimento muscular, boa deposição de gordura e menor proporção de ossos (Fernandes et al, 2010). Entretanto, melhorar a nutrição para os cordeiros, por meio da utilização de suplementos convencionais, pode elevar os custos de produção (Carvalho et al, 2006), o que motiva o uso de alimentos alternativos na nutrição desses animais.…”
