1. A 70-d experiment was conducted to determine the response of 26-week-old laying pullets to cereal-free diets based on maize offal, cassava peel and full-fat cashew nut meal (CNM) in comparison with a standard 550 g maize/kg reference diet. The 4 test diets all contained 315 g CNM/kg 232.5, 155.0, 77.5 and 0.0 g/kg of maize offal in combination with 77.5, 155.0, 232.5 and 315.0 g/kg of cassava peel, respectively. 2. Pullets fed on the 4 CNM-based diets consumed (P<0.05) less food than those fed on the reference diet; they also had lower (P<0.05) rates of lay, produced less (P<0.05) egg mass, had lower (P<0.05) food conversion efficiencies and their eggs had a lighter (P<0.05) yolk colour. Pullets fed some of the CNM-based diets also gained more (P<0.05) weight, the heaviest (P<0.05) being birds reared on the diet containing 315 g/kg cassava peel. Egg weight, shell thickness and albumen height from all eggs were similar. Pullets fed on the CNM-based diets had inferior (P<0.05) retention of dry matter and protein. 4. It was concluded that feeding full-fat CNM allowed for high dietary inclusion rates of cassava peel and maize offal and the resultant diets, which contained no maize, supported satisfactory performance of laying hens.
An experiment was carried out to investigate the performance and nutrient digestibility ofWcst African dwarf growing rams*/ mixture of Panicum maximum and Tridax procumbens supplemented with Cajanus cajan leaves for 56 days feeding trial. A total of twelve WAD rams were randomly allocated to three treatments with four animals per treatment while two animals served as replicate. The experimental diet was fed at 3% body weight of individual animals while Cajanus cajan leaves were supplemented at varied inclusion levels. The results revealed that animals led T, recorded the least weight gain* (36.96g/day) while the highest weight gain (56.42g/day) was recorded for T3 The daily weight gain of animals wa.s. significantly different across all treatments (P<0. 05). The highest DMI (18.30kg) was recorded on the T1, and the least value of DM1(17,40kg) was recorded in T3. The highest led efficiency ratio (0.18) and the lowest value (0.11) were observed in animals fed T, and T, diet respectively. There were significant differences (P<0.05) in the nutrient digestibility parameters of the experimental animals. The results showed that T1(100% sole Cajanus cajan leaves) promoted the best thy matter (DM) digestibility (89.56%) which was enough to meet the production and maintenance requirement of small ruminants while the lowest value (88.67%) of DMD was recorded in T2. The highest crude protein (CP) digestibility (13.20%) was observed in T, diet. The highest value for crude, fibre digestibility (38.95%) and the lowest value (35.35%) were observed in animals. T, and 'litho` respectively. In conclusion, supplementation of Cajanus cajan1 leaves with mixture of-Tridar procumbens and Punicum maximum as basal diet for feeding sheep enhanced nutrient intake, growth performance and improved nutrient digestibility without health challenges to the animals
Browse legume plants particularly pigeon pea forage generates a lot of underutilized leaves which if properly harnessed can be a cheaper source of nutrients for small ruminant animal production, during dry season feed shortages. In this study, the nutrient digestibility and nitrogen utilization of West African dwarf growing rams fed differently processed Cajanus cajan leaves and Panicum maximum basal diet for 56 days feeding trial. A total of sixteen(16) growing WAD rams between 6 - 9 months with an average body weight of 7.00 - 12.00k were randomly allocated to 4 treatments with 4 rams each and 2 rams per replicate. The experimental diet was fed at 3% body weight of individual ram while fresh, wilted, and dried forms of Cajanus cajan leaves supplemented at varied inclusion levels (0%, 30% fresh, 30% wilted and 30% dried) with Panicum maximum. There were significant (P<0.05) differencesin all parameters determined on nutrient digestibility across the dietary treatments. Animals maintained on T (70% Panicum maximum and 30% dried Cajanus cajan leaves) had the 4 highest dry matter digestibility (60.46%), while the lowest value (48.56%) for DMD was recorded in T diet. Rams fed T diet had the highest mean crude protein digestibility (CPD) 1 2 value of 11.30%, followed by T (10.68%), 10.02% for T , while T diet had the lowest mean 2 1 4CPD of 9.21%. Rams fed T diet had the highest mean crude fibre digestibility (CFD) value of 1 37.65%, while 35.03, 33.18 and 32.71 were recorded for T , T and T diet respectively. T was 4 2 3 4 observed to have the highest mean ash digestibility value of 17.07% with T , T and T having 3 1 2 the value of 16.02, 14.28 and 13.36 respectively. There were significant (P<0.05) differences in all parameters determined on nitrogen utilization across the dietary treatments. Rammaintained on T diet had the highest mean intake of 4.42g/d while T diet had the lowest 2 1 mean value of 2.64g/d. The lowest mean nitrogen balance (NB) of 0.43g/d was observed in rams fed T diet while rams on T diet had the highest NB value of 2.18g/d. Rams fed T diet 1 2 4 had the highest faecal nitrogen value of 2.14g/d. However, rams maintained on T diet had 4 the highest value urinary nitrogen of 1.07g/d. The nitrogen utilization fluctuatedsignificantly (P<0.05) across the dietary treatments. It can be concluded that supplementation of fresh Cajanus cajan forages at 30% inclusion with Panicum maximum at 70% for growing rams can enhance nutrient utilization in terms of crude protein digestibility and nitrogen utilization without any deleterious effects on the animals.
