Abstract

This study was conducted to assess the effect of increasing amounts of 3-hydroxy-3-methylbutyrate (HMB) and 2-oxoisocaproate (KIC) given as a dietarysupplement on performance and body composition in growing rabbits. In addition, plasma, liver, muscle and duodenum cholesterol were also determined. Male White Termonde rabbits were fed either experimental diets containing increasing amounts of HMB (range 0.005-0.1% of the dietary dry matter) and KIC (range 0.02-0.1% of the diet dry matter) or control diets containing CaCO3 for 9 weeks. Experimental treatment did not affect growth rare. protein content of the total carcass did not differ among groups, whereas carcass fat content decreased by up to 30%, in proportion to the amount of HMB and KIC administered (p < 0.05). The same protein content calculated as a percentage of dry matter increased by 12% and protein:fat ratio by 42% in the rabbits receiving 0.1% of dietary HMB (p < 0.05). Total blood cholesterol decreased during the first 3 weeks of treatment and was sustained at that low level (p < 0.05). Duodenum cholesterol decreased up to 15% (for 0.1% KIC p <0.01). In conclusion, dietary HMB/KIC supplementation can beneficially affect some carcass characteristics in rabbits, especially concerning elevatedbody protein:fat ratio and decreased plasma and intestinal cholesterol.
