Abstract

The effect of replacement of maize grain by animal fat in a diet with highlevel of acid detergent fibre (27%) on diet digestibility, rumen fermentation and energy content of the diet was evaluated. Six fistulated wether sheep were used in a 2 x 2 Latin square experimental design in three replicates. Forage : concentrate ratio in the diets was 47.7 : 52.3 and animal fat contributed to concentrates by 7%, replacing maize on a weight basis. Digestibility of ether extract was increased (P <0.001) by 13.1% for the diet with fat compared to the diet without fat, while digestibility coefficients ofthe other nutrients were unaffected. The energy content of the diet with fat increased by 3.4% (P <0.05). The inclusion of animal fat to sheep diet increased significantly the molar proportion of propionate (P <0.05) by 10.7% and the crude protein degradability (P <0.001) by 4%, and decreased the molar proportion of butyrate by 6.1% (P <0.05), the acetate to propionate ratio (P <0.01) by 13.2%, and the protozoa counts by 32% (P <0.001). The results showed that animal fat can replace cereal grains in sheep diets up to the level of 5% without any problem on rumen fermentation process.
