This study aimed to evaluate the carcass characteristics and meat quality of feedlot goat kids fed high-concentrate diets with licury cake. Forty crossbreed non-castrated Boer × mixed breed goat kids with an average age of 4 months and an initial average body weight of 20.15 ± 2.79 kg were randomly distributed in a completely randomized design with four experimental diets containing licury cake at 0, 10, 20, and 30% of total dry matter. Dry matter, crude protein, and total digestible nutrient intakes were reduced linearly (P < 0.01) from the inclusion of 10% of licury cake in the goat kids’ diet. Slaughter weight, hot and cold carcass weights and yields decreased (P < 0.01) from the inclusion of 10% of licury cake. Lightness (P = 0.032), redness (P = 0.012) and yellowness (P = 0.021) increased, whereas the Warner-Bratzler shear force decreased (P = 0.032) with the licury cake inclusion in goat kids diets. Licury cake promoted a quadratic increase in polyunsaturated fatty acids, CLA precursors (C18:1 trans 11 and C18:2 n-6), and desirable fatty acids. The use of up to 10% licury cake in diets for goat kids maintains the carcass weight and yield, increase lauric (C:12), vaccenic (C18:1 trans-11), linoleic (C18:2 n-6), linolenic (C18:3 n-3), and desirable fatty acids in meat. This level of use of licury cake is, therefore, recommended for use in high-concentrate diets for feedlot goat kids.

用高脂饮食饲喂高脂饮食的山羊羔羊的kids体特征和肉质

本研究旨在评估饲喂高浓度日粮和糖蛋糕的山羊饲养场的山羊羔的car体特性和肉质。将40个平均年龄为4个月,初始平均体重为20.15±2.79千克的不-割的布尔×混合种山羊山羊羔随机分配为完全随机设计,其中四种实验饮食分别含有0、10、20的糖水饼,以及总干物质的30%。在山羊儿童的饮食中加入10%的糖水饼后,干物质,粗蛋白和总可消化营养摄入量线性降低(P <0.01)。由于加入了10%的糖饼,屠宰重量,hot体冷热重量和单产下降(P <0.01)。亮度(P  = 0.032),红色(P  = 0.012)和黄度(P  = 0.021)增加,而在山羊儿童饮食中加入了糖蛋糕则Warner-Bratzler剪切力降低(P = 0.032)。柠檬蛋糕促进了多不饱和脂肪酸,CLA前体(C18:1反式11和C18:2 n-6)和所需脂肪酸的二次增加。山羊羔羊的日粮中使用高达10%的糖水蛋糕可维持the体重量和产量,增加月桂酸(C:12),真空(C18:1 trans-11),亚油酸(C18:2 n-6),亚麻酸(C18:3 n-3),以及肉中所需的脂肪酸。因此,建议将这种水平的糖水蛋糕用于肥育场山羊孩子的高浓度日粮中。
