This study was conducted to examine the effects of including palm kernel cake (0, 120, 240, and 360 g kg−1) in high-concentrate diets for feedlot goats on carcass traits and meat quality. Thirty-two non-pregnant, mixed-breed goats (average age: 1 year; initial body weight: 24.70 ± 3.72 kg) were evaluated in a completely randomized experimental design. Hot (P = 0.007) and cold (P = 0.008) carcass weights responded quadratically, with maximum values of 16.4 and 16.3 kg estimated at the palm kernel cake inclusion levels of 125.0 and 116.7 g kg−1, respectively. Loin eye area (P = 0.042), subcutaneous fat thickness (P = 0.013), fatness score (P = 0.014) and the morphometric measurements of external length (P = 0.009) and chest width (P = 0.013) decreased, whereas chest circumference (P = 0.037) responded quadratically to the increasing inclusion levels. The diets did not influence (P > 0.05) the physicochemical characteristics or proximate composition of goat meat. Principal component analysis of sensory attributes resulted in the separation of the meat samples. The inclusion of up to 115.0 g kg−1 of palm kernel cake in high-concentrate diets for feedlot goats provides heavier carcasses and increases consumers’ acceptance of goat meat.

高浓度日粮棕榈仁饼对肥育场山羊car体性状和肉品质的影响

进行了这项研究,以检验高浓度日粮中饲喂棕榈仁饼(0、120、240和360 g kg -1)对car肥山羊的s体性状和肉质的影响。在完全随机的实验设计中评估了32只未怀孕的混种山羊(平均年龄:1岁;初始体重:24.70±3.72 kg)。热(P  = 0.007)和冷(P  = 0.008)car体重量呈二次响应,在棕榈仁饼夹杂物含量分别为125.0和116.7 g kg -1时,最大值分别为16.4和16.3 kg 。腰眼面积(P  = 0.042),皮下脂肪厚度(P  = 0.013),脂肪评分(P = 0.014),而外部长度(P  = 0.009)和胸部宽度(P  = 0.013)的形态计量学测量值降低,而胸围(P  = 0.037)对夹杂物含量增加的平方响应。日粮不影响(P> 0.05)山羊肉的理化特性或附近组成。感官属性的主成分分析导致了肉样品的分离。在育肥山羊的高浓度日粮中添加了115.0 g kg -1的棕榈仁饼,可提供较重的car体,并增加了消费者对山羊肉的接受度。
