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. •Meat lipids from grass-fed buffaloes and cattle males were compared at two ages.•Lean meat from both species showed low cholesterol levels.•Content of several individual fatty acids varied with the species.•Species similarities were found in fatty acid ratios.•Atherogenic index was lower in Buffalo, and may be beneficial on human health.
