Effect of different phytoadditive mixtures on nutrient utilization, growth performance, milk production and fatty acid profile of Black Bengal goats
摘要
In this study, effect of two phytoadditive mixtures comprising Curcuma longa and Allium sativum (PAM-1) or Curcuma longa and Ocimum sanctum (PAM-2) were studied on nutrient utilization, growth, milk production, milk quality and milk fatty acids in Black Bengal goats (BBG). In this study, 21 female BBG with similar body weight (P = 0.853) and age (3–4 months) were split into three comparable groups namely, Control (no supplementation), T1 (15 g PAM-1 in per kg of dry matter of conc. mixture) and T2 (15 g PAM-2 in per kg of dry matter of conc. mixture). Statistical analysis revealed higher dry matter intake (P < 0.01) in T1 and T2 groups. Improved (P < 0.001) digestion of dry matter, crude protein, ether extract and organic matter were reported in T1 and T2 groups with similar fiber digestion. Improved final BW, ADG, FCR and BCS (P < 0.001) was found in treatment groups. Treatment groups had higher milk production (P < 0.001) and MBRT minutes with similar milk composition. Higher (P < 0.001) total unsaturated fatty acids, CLA contents with reduced SFA content was observed in treatment groups. Therefore, it may be concluded that inclusion of phytoadditive mixtures PAM-1 and PAM-2 (15 g/kg DM of conc. mixture) improves nutrient utilization, growth performance, milk production, milk quality and milk fatty acids in Black Bengal goats.
