Male (n=66) water buffalo (Buffalo) and Brahman-influenced cattle (Brahman) were born, raised, weaned, fattened on grazing savannah and harvested at two different ages (19 and 24months) to compare lipid composition of the longissimus thoracis muscle. Half of the animals were castrated at seven months of age (MOA) to examine the castration effects. At 24 MOA Brahman steers showed the highest content of total lipids (P<0.05). No significant variation was detected in cholesterol content for either the main or interaction effects in the age groups. Some individual fatty acids varied with the species (P<0.05), however, interspecific similarities were found in fatty acid ratios. For health-related indices, only atherogenic index (AI) showed lower values in favor of Buffalo meat (P<0.05) at both harvesting ages. Although, meat derived from both bovid groups was leaner and showed lower cholesterol level, AI indicates that Buffalo meat might be beneficial from a human health standpoint.
雄性（n = 66）水牛和受婆罗门牛影响的牛在热带草原上出生、饲养、断奶、育肥，并在两个不同年龄（19个月和24个月）屠宰，以比较胸最长肌的脂质组成。一半的动物在7月龄时去势，以研究去势的影响。在24月龄时，婆罗门阉牛的总脂质含量最高（P<0.05）。在各年龄组中，无论是主要效应还是交互效应，胆固醇含量均未检测到显著差异。一些个体脂肪酸因物种而异（P<0.05），然而，在脂肪酸比例上发现了种间相似性。对于与健康相关的指标，仅动脉粥样硬化指数（AI）在两个屠宰年龄均显示水牛的数值较低，有利于水牛肉（P<0.05）。虽然，来自这两个牛科动物组的肉更瘦且胆固醇水平较低，但AI表明从人类健康角度来看，水牛肉可能有益。
