Feedlot Lambs

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 (p > 0.05) the weight gain and carcass characteristics, with the exception of the subcutaneous fat thickness (p < 0.01), which was higher in animals fed diets with higher levels of WCG. Lightness (L *; p = 0.04), yellowness (b *; p < 0.01), shear force (p = 0.04), linoleic fatty acid concentrations (p = 0.03), and total polyunsaturated fatty acids (p = 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.

The effects of breed and diet containing different types of silages on meat quality parameters and fatty acid profile of m. longissimus lumborum (MLL) were evaluated in a total of 30 Czech Fleckvieh (CF), Charolais (CH) and Charolais &times; Czech Fleckvieh (CH &times; CF) bulls. The animals were fed two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal mixture silage and lucerne silages) with different concentrations of dietary energy and fatty acids. The MLL from CH bulls had the lowest content of dry matter (P &lt; 0.01), less protein (P &lt; 0.01) and lighter meat (P &lt; 0.01) compared to the CF. The extensive LCS diet reduced dry matter (P &lt; 0.01) and intramuscular fat (P &lt; 0.01) and increased the content of hydroxyproline (P &lt; 0.05). The CH bulls exhibited higher PUFA n-3 (P &lt; 0.05) and lower MUFA (P &lt; 0.05) compared to the CF, with the CH &times; CF being intermediate. The LCS diet enhanced the proportions of PUFA (P &lt; 0.05) and PUFA n-3 (P &lt; 0.001) and reduced MUFA (P &lt; 0.001). In conclusion, both breed and diet affected the meat quality and fatty acid profile of the intramuscular fat of the bulls. The replacement of maize silage with the legume-cereal mixture and lucerne silages in the diet reduced the concentration of intramuscular fat and improved its fatty acid profile from the human nutrition perspective.

This study aimed to evaluate the effects of supplementation with sunflower seeds and vitamin E for fattening lambs, on the chemical composition, cholesterol, vitamin E level, fatty acid profile and lipid oxidation of meat from sheep. Four treatments were evaluated, as follows: SC – basal diet consisting of sugarcane + concentrate; SCS – basal diet supplemented with sunflower seed; SCE – basal diet supplemented with 1000 mg vitamin E; SCSE – basal diet supplemented with sunflower seed and 1000 mg vitamin E. The Longissimus lumborum muscle of 32 Ile de France lambs, which were slaughtered when their bodyweight reached 32 kg, was used. The chemical composition of the lamb meat was not significantly different (P > 0.05) between the treatments. Sunflower seed supplementation increased (P < 0.05) the levels of linoleic acid, vaccenic acid and conjugated linoleic acid. Inclusion of vitamin E in the diet increased (P < 0.05) the concentration of vitamin E in the meat while decreasing lipid oxidation. Considering the current demand for healthy foods, inclusion of sunflower seeds and vitamin E in the diet of sheep is a viable possibility.

ABSTRACT: The aim of this study was to evaluate the carcass characteristics and the physicochemical parameters, centesimal composition, and fatty acid profile of the longissimus lumborum muscle of crossbred steers on a Brachiaria (Syn. Uruchloa) brizantha cv. Marandu pasture during the growing and finishing phases. Twenty-two uncastrated steers ½ Holstein/Zebu, with an average initial weight of 210 kg ± 8.2 kg and eight months of age, were distributed in a completely randomized design, in which the experimental period was fractionated in to three seasons associated with two nutritional plans (NP1 and NP2) and 11 animals by treatment: NP1- mineral mixture ad libitum in rainy seasons + nitrogen/energy supplement at 1 g.kg-1 body weight (BW) in the dry season; and NP2 - nitrogen/energy supplement at 2 g.kg-1 BW in rainy season 1 and in the dry season + nitrogen/energy supplement at 1 g.kg-1 BW in rainy season 2, provided daily at 1000 h. Of the carcass measurements, differences were only observed (p>0.05) between the nutritional plans for loin-eye area corrected for 100 kg of hot carcass weight. Among the physicochemical parameters, only shear force was influenced (p>0.05) by the treatments, with higher values obtained in Nutritional Plan 1. The centesimal composition and fatty acid profile were not influenced (P<0.05) by supplementation. Nutritional plans used in the growing and finishing phases involving low levels of protein-energy supplementation do not lead to changes significant in carcass characteristics and meat. Nutritional Plan 1 is the most appropriate because it presents a lower cost.
