ResumoObjetivou-se avaliar as características quantitativas das carcaças de cordeiros da raça Santa Inês em confinamento, abatidos com três espessuras gordura subcutâneas (EGS) diferentes. Foram utilizados 24 cordeiros, machos não castrados Inês, aproximadamente 100 dias idade e peso vivo 22,7±3,75kg, divididos aleatoriamente tratamentos: abates espessura subcutânea 2,0; 3,0 4,0mm.

Although fumonisins are identified as responsible for alterations in weight gain, little information is available on their effects expression of growth-related genes, especially Nile tilapia ( Oreochromis niloticus ) fingerlings. In this study, fingerlings were treated with increasing levels fumonisin B 1 (FB and 2 (diets 0, 20, 40, 60 mg/kg) to evaluate gain (WG), feed intake (FI), efficiency (FE), growth hormone receptor (GHR) insulin factor (IGF-1) mRNA liver fish. All variables evaluated...

All animals wormed thirty days before first data collections, which done fortnightly July 2005 March 2006. color ocular conjunctiva...
Twenty-four female lambs of the Pantaneiro genetic group, with approximately 100 days age, average body 16.24 ± 1.78 kg, were slaughtered 2.0, 3.0 and 4.0 mmof subcutaneous fat thickness, measured by ultrasound in Longissimus, to evaluate allometric growth. Lambs fed a complete pelleted diet calculated ensure daily weight gain of0.30 kg. Slaughtering was performed as reached pre-established thickness. After 24 hours cold chamber at 4ºC, chilled carcasses cut half weighed. The right side...

Lipid composition and sensory traits of the meat from female lambs Pantaneiro genetic group slaughtered with 2.00, 3.00 4.00 mm subcutaneous fat thickness (SFT) were evaluated by ultrasound. Twenty-four weighing 16.24 ± 1.78 kg confined in feedlots. These animals fed pelleted diet formulated to provide a daily weight gain 0.30 kg. As reached pre-set SFT weekly evaluation ultrasound, they on day following measurement, regardless their weight. The did not alter fatty acid profile lambs. For...
Linseed plays an important role in animal nutrition as it contains long-chain fatty acids its composition, which, once absorbed, are incorporated into meat and milk. For evaluate the concentration of Longissimus dorsi muscle culling ewes fed diets containing levels inclusion linseed, 88 were used with average initial body weight 37.65 ± 6.98 kg distributed a completely randomized design 12 treatments. Treatments consisted interaction between linseed (0, 5, 10, 15%) days feedlot (30, 45, 60)....
