The study evaluated the growth performance digestibility and nitrogen utilisation of West African Dwarf (WAD) sheep fed with Albizia lebbeck - cassava peel silage and Panicum maximum. Sixteen female WAD sheep (6“7 months old and average live weights of 11 kg) were randomly allotted into four dietary treatments in a complete randomized design. Dietary treatments of A. lebbeck - cassava peel silage are: Diet 1 (60 Cassava peel 25 A. lebbeck 15 P. maximum) Diet 2 (45 Cassava peel 40 A. lebbeck 15 P. maximum) and Diet 3 (30 Cassava peel 55 A. lebbeck 15 P. maximum) while Diet 4 (100 P. maximum) is the control. The pH values (4.27“5.39) NH3-N (0.089“0.125) lactic (0.72“1.08) and butyric (7.04“10.53) acids contents of silages differed (p 0.05). Intakes of dry matter (68.6“71.3 g/kg W0.75/d) and crude protein (15.9“18.4 g/kg W0.75/d) of sheep were similar (p 0.05) across treatments while total feed intake (840 g/d) and weight gain (46.07 g/d) of sheep fed diet 1 were superior (p 0.05) to other treatment groups. Although sheep fed diet 4 had the best (p 0.05) feed conversion ratio silage diet was efficiently utilized by the sheep fed diet 1. Nutrient digestibility varied (p 0.05) across treatment groups. The values of apparent nitrogen digestibility (69.33) nitrogen absorbed and retained was highest (2.08 and 1.97 g/d) in sheep fed diet 1 while nitrogen absorbed and retained was lowest (1.37 and 1.12 g/d) in sheep fed diet 3. In conclusion WAD sheep fed diet 1 performed remarkably in terms of feed intake weight gain and N-utilisation. Therefore A. lebbeck-cassava peel silage can be a viable option for sheep feeding in the dry season when grass quality is low.

Abstract

The study evaluated the growth performance digestibility and nitrogen utilisation of West African Dwarf (WAD) sheep fed with Albizia lebbeck - cassava peel silage and Panicum maximum. Sixteen female WAD sheep (6“7 months old and average live weights of 11 kg) were randomly allotted into four dietary treatments in a complete randomized design. Dietary treatments of A. lebbeck - cassava peel silage are: Diet 1 (60 Cassava peel 25 A. lebbeck 15 P. maximum) Diet 2 (45 Cassava peel 40 A. lebbeck 15 P. maximum) and Diet 3 (30 Cassava peel 55 A. lebbeck 15 P. maximum) while Diet 4 (100 P. maximum) is the control. The pH values (4.27“5.39) NH3-N (0.089“0.125) lactic (0.72“1.08) and butyric (7.04“10.53) acids contents of silages differed (p 0.05). Intakes of dry matter (68.6“71.3 g/kg W0.75/d) and crude protein (15.9“18.4 g/kg W0.75/d) of sheep were similar (p 0.05) across treatments while total feed intake (840 g/d) and weight gain (46.07 g/d) of sheep fed diet 1 were superior (p 0.05) to other treatment groups. Although sheep fed diet 4 had the best (p 0.05) feed conversion ratio silage diet was efficiently utilized by the sheep fed diet 1. Nutrient digestibility varied (p 0.05) across treatment groups. The values of apparent nitrogen digestibility (69.33) nitrogen absorbed and retained was highest (2.08 and 1.97 g/d) in sheep fed diet 1 while nitrogen absorbed and retained was lowest (1.37 and 1.12 g/d) in sheep fed diet 3. In conclusion WAD sheep fed diet 1 performed remarkably in terms of feed intake weight gain and N-utilisation. Therefore A. lebbeck-cassava peel silage can be a viable option for sheep feeding in the dry season when grass quality is low.
