Effect of browse plant foliage supplementation on the performance of buckling goats fed threshed sorghum top basal diet.

The effect of browse plants (Piliostigma thonningii, Daniellia oliveri, Afzelia africana, Pterocarpus erinaceus and Annona senegalensis) supplementation on nutrient intake, digestibility, nutritive value and N utilization and growth performance of buckling goats fed threshed sorghum top (TST) was investigated using 24 Red Sokoto goats (9.0 ± 0.25 kg) body weight (BW) which were randomly assigned to one of the six diets in a completely random design. Intakes of dry matter (DM) and nutrients, feed conversion ratio, digestibility of nutrients except for neutral detergent fibre (NDF) and acid detergent fibre (ADF), digestible organic matter (DOM), digestible crude protein (DCP), energy concentration, N utilization and average daily gain were superior (P < 0.05) in TST-supplemented diets compared to sole TST diet. Among the supplemental fodders, intakes of forage, DM, condensed tannins and most of the nutrients; digestibility of DM, crude protein (CP) and non-fibre carbohydrate, DOM and DCP; and N absorbed, balance and retention were greater (P < 0.05) in A. africana relative to the other fodders. Results indicate that the entire browse fodders are good supplements to low quality TST, though A. africana appears to have a better nutritive value.
