nutrient 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 × 4 latin square design experiment. data were collected on dry matter intake (dmi), nutrient intake and digestibility. simple linear regression and correlation were used to assess relationships between some of the digestion components.there were no significant (p>0.05) differences in dmi among the treatmentmeans.the nitrogen intake (g/d) was significantly (p0.05). urinary nitrogen was significantly (p
