متن کاملNutrient Intake and Digestibility by West African Dwarf (WAD) Sheep Fed Graded Levels of Pigeon Pea Seed Meal
A study was carried out to evaluate nutrient intake and digestibility by West African Dwarf (WAD) sheep fed graded levels of dietary pigeon pea seed meal (PSM). Four diets designated A, B, C and D were formulated to contain 0, 10, 20, and 30% levels of PSM, respectively. Four WAD rams aged between 15 and 17 months and weighing between 16 and 19 kg were used to conduct digestibility study in a 4...
