This study investigated the effects of lasalocid supplementation on the diet of goats to improve carcass characteristics, meat quality traits, and fatty acid content. Sixty intact male Ardhi goats were used. The kids were divided into four treatment groups, each with 15 animals, and further subdivided into five subgroups, each with three goats, in a completely randomized design. Data on carcass characteristics, meat quality, and fatty acid profiles were obtained. The LAS treatment significantly affected the chill shrinkage and dressing percentage on the empty body weight. Saturated fatty acids decreased, whereas essential polyunsaturated fatty acids increased with the addition of supplements. In conclusion, including lasalocid in the diets of Ardhi goats enhanced the carcass characteristics of the animals, whereas meat quality traits were not negatively affected by the supplement.
本研究调查了添加拉沙洛西对山羊日粮的影响，以改善胴体特性、肉质性状和脂肪酸含量。使用了60只未阉割的雄性阿尔迪山羊。这些羔羊被分为四个处理组，每组15只动物，并进一步细分为五个亚组，每组三只山羊，采用完全随机设计。获得了关于胴体特性、肉质和脂肪酸谱的数据。拉沙洛西处理显著影响了冷收缩和以空腹体重计算的屠宰率。添加补充剂后，饱和脂肪酸减少，而必需多不饱和脂肪酸增加。总之，在阿尔迪山羊的日粮中添加拉沙洛西可改善动物的胴体特性，而肉质性状不受该补充剂的负面影响。
