Effects of supplementing Leucaena pallida based multi-nutrient block on feed intake and body weight performance of goats fed poor-quality forage in semi-arid Tanzania during dry season

Abstract

The study examined how three types of multi-nutrient blocks (urea-based multi-nutrient block, sunflower seedcake-based multi-nutrient block and Leucaena pallida leaf meal-based multi-nutrient block) affected the feed intake and growth performance of goats. While the dry matter intake of the basal diet remained unaffected by the multi-nutrient block supplements, the total feed intake was notably higher in the supplemented groups. Leucaena pallida-based multi-nutrient block had the highest intake while sunflower seedcake-based multi-nutrient block had the lowest. The preference for Leucaena pallida-based multi-nutrient block over sunflower seedcake-based multi- nutrient may be due to the appealing aroma and texture of Leucaena pallida. Leucaena pallida-based block supplementation reduced weight loss compared to the non- supplemented group. Overall, multi-nutrient blocks with Leucaena pallida could be a beneficial supplement for feeding growing goats during the dry season.
