| description | The whole corn germ (WCG), due to its desirable nutritional characteristics, has been studied as feed for ruminants. This study aimed to evaluate the effects of WCG inclusion as a linoleic acid source in diets for feedlot lambs on carcass characteristics, physicochemical composition, sensory attributes, and fatty acid profile of the meat. Forty non-castrated, crossbreed Dorper x Santa Inês lambs were distributed in a completely randomized design to evaluate the inclusion levels (0, 30, 60, 90, and 120 g/kg dry matter (DM)) of whole corn germ (WCG) in the diet. The dietary inclusion of WCG did not influence (<i>p</i> > 0.05) the weight gain and carcass characteristics, with the exception of the subcutaneous fat thickness (<i>p</i> < 0.01), which was higher in animals fed diets with higher levels of WCG. Lightness (L *; <i>p</i> = 0.04), yellowness (b *; <i>p</i> < 0.01), shear force (<i>p</i> = 0.04), linoleic fatty acid concentrations (<i>p</i> = 0.03), and total polyunsaturated fatty acids (<i>p</i> = 0.04) had a quadratic increase due to WCG inclusion in the diets. The use of up to 120 g/kg DM of WCG in lamb diets does not affect the carcass characteristics, physicochemical composition, and sensory attributes of the meat. Despite this, the best polyunsaturated fatty acid profile in lambs’ meat is obtained using 76.7 g/kg DM of WCG. |
