Características da carcaça de bovinos de quatro grupos genéticos submetidos a dietas com ou sem adição de gordura protegida

Abstract: Com o objetivo de avaliar o rendimento e as características de carcaça de quatro grupos genéticos de bovinos, foram abatidos 32 animais machos inteiros, dos grupos Nelore (N), F1 Canchim x Nelore (CN), F1 Limousin x Nelore (LN) e F1 Aberdeen Angus x Nelore (AN), com idade aproximada de 19 meses e peso vivo médio de 558 kg, terminados em regime de confinamento, recebendo dietas com ou sem adição de gordura protegida, durante 166 dias. O delineamento experimental utilizado foi inteiramente casualizado, com quatr… Show more

“…These results reflected the greater energy uptake offered to the animals fed the diets containing oil, promoting higher amounts of nutrients, thus resulting in more growth. Jaeger et al (2004), in turn, working with four distinct breed groups fed diets with or without protected fat, did not find any differences for slaughter weight and hot carcass weight, but in this case, all diets evaluated had the same amount of energy (720 g/kg of dry matter from total digestible nutrients).…”

“…Both the loin eye area and the backfat thickness were superior to those obtained by Donicht et al (2011) also evaluating feedlot-finished Nellore young bulls receiving Megalac-E ® (3.0 or 6.0% in dry matter) in the diet (average of 66.5 cm 2 and 4.51 mm, respectively). On the other hand, the values found by Jaeger et al (2004) were higher, and these authors also evaluated diets with and without addition of protected fat for the same animal category and breed, but slaughtered the animals at 19 months of age, approximately 530.75 kg slaughter weight and 296.94 kg carcass weight.…”

“…Segundo Jaeger et al (2004), gorduras e óleos têm sido utilizados na alimentação de ruminantes em substituição às altas proporções de grãos, com o intuito de aumentar a densidade energética da dieta e melhorar a eficiência alimentar. Porém, Homem Júnior et al (2010) observaram que dietas para terminação de cordeiros Santa Inês, com elevada proporção de concentrado, contendo grãos de girassol ou gordura protegida proporcionaram bom desempenho aos animais, mas não diferiram da dieta sem adição de fontes lipídicas.…”

“…However, no effects on yields and carcass weights were observed in various studies including the study done by Jaeger et al (2004). They used four different genetic groups fed diets either with or without protected fat.…”
