Pigeon pea (Cajanus cajan; CJ), a browse legume, generates a lot of foliage which may be suitable for livestock feeding. The foliage could serve as a cheap source of nutrients to alleviate dry season feed shortage affecting ruminant production. A total of 30 growing WAD rams of 6 – 9 months old weighing 10.75 – 11.68 kg were randomly grouped into six rams per treatment in a completely randomized design for 90days feeding trial to assess the growth performance and nutrient digestibility of rams fed varying proportions of Cajanus cajan hay with Panicum maximum was carried out at the Teaching and Research Farm of Oyo State College of Agriculture and Technology Igbo-ora, Nigeria. The CJ foliage cut at 8 weeks after planting and air-drying for 3 to 4 days were mixed in varying proportions with fresh PM (Panicum maximum) as the experimental diets (ED) and fed for each individual ram per day at 3% body weight. The ED were: T1 (100%PM), T2 (70PM30CJ), T3 (50PM50CJ), T4 (30PM70CJ) and T5 (100%CJ). There were significant (P<0.05) differences in all parameters determined on growth performance across the dietary treatments. Ram maintained on T3 diet had the highest Dry matter intake (51.18g/d), while the lowest value (45.54g/d) for DMI was recorded on ram fed diet T5. The results revealed that ram fed diet T₁ recorded the least daily weight gain (8.00g/d) while the highest daily weight gain (18.22g/d) was recorded in ram fed diet T4 that contained 30%PM70%CJ. The feed conversion ratio (FCR) ranged 4.65 – 10.83 showed significant difference across all treatments. Hence, ram fed diet T4 that contained 30%PM70%CJ hay recorded the best feed utilization value of 4.65. There were significant (P<0.05) differences in all parameters determined on nutrient digestibility across the dietary treatments. Rams maintained on T3 (50%PM50%CJ had the highest dry matter digestibility (88.24%), while the lowest value (86.87%) for DMD was recorded in T2 diet. Rams fed T5 diet had the highest crude protein digestibility (CPD) value of 81.72%, followed by T4 (78.54%), while T1 diet had the lowest CPD of 63.32%. Rams fed T5 diet had the highest crude fibre digestibility (CFD) value of 71.97%, while 67.32, 65.89%, 68.10% and 67.82% were recorded for T1, T2, T3 and T4 diet respectively. T5 was observed to have the highest ash digestibility value of 29.10% with T1, T2, T3 and T4 having the value of 25.21%, 23.08%, 24.69% and 28.14% respectively. It can be concluded that feeding of fresh Panicum maximum (PM) forages at 30% inclusion with Cajanus cajan hay (CJ) at 70% for growing rams diet has a good nutrient profile and enhanced growth performance of the rams in terms of weight gain and feed utilization and improved nutrient utilization in terms of crude protein digestibility without any deleterious effects on the animals.
