  Two hundred 4-week old Anak 1000 Strain of broliles were used in a 28-day feeding trial in a completely randomized design to evaluate the performance of finisher broiler chicken fed varying levels of maize further replicated four times. Treatments having 0, 15, 30, 45 and 60% maize offal replaced corresponding weights of whole maize in the diets. Feed and water were supplied ad libitum. Routine vaccination programme and medication typical of measured. Results who that birds on control (0%) and 30% maize offal with weight gains of 1.56 kg and 1.55 kg respectively did not differ significantly (p>0.05) but were significantly (p>0.05) heavier than those on 15, 45 and 60%. Cost of producing one kg of feed declined from N54.50 in the conrol to N44.50 at 60% inclusion level of maize offal which differed significantly (p>0.05). Feed cost/kg gain (N) was lowest for birds on T3 (30% maize offal), N 145.08 which differed significantly (p>0.05) from the other treatments.

  A 28 day feeding trial was conducted using 160 marshal strain of day old broiler chicks fed 0, 5, 10 and 15% levels of Bambara Seed Offal (BSO) in a completely randomized design where BSO replaced soyabean meal weight for weight. Each of the four dietary treatments was further replicated four times. Routine vaccination and medication typical of broilers were strictly adhered to. The initial weight, final weight, weight gain, feed intake, feed conversion ratio, feed cost/kilogram and feed cost/kilogram weight gain were measured. Results show that birds on control (0% BSO) and T2 (5% BSO) with weight gains 584.78 and 583.48 respectively did not differ significantly (p>0.05) but were superior to those of levels 10% and 15% BSO (539.4 g and 505.0 g respectively). Both feed conversion ratio and feed cost/kg declined as the level of BSO increased from 0-15% while feed cost/kg weight gain did not maintain any particular trend. Treatment 2 (5% BSO) had the lowest cost of production feed wise. The control (0% BSO) and treatment 2 (5% BSO) were statistically similar (p>0.05) for final weight, weight gain, feed intake and feed conversion ratio.

  The study investigated the effects of Aloe vera as leaf protein concentrate for cockerels. It was conducted with 72 - day old cockerels which at 3 weeks of age were randomly allotted to 3 dietary treatments of 24 birds each with 3 replicates per treatment. The rations were standard commercial feed 0% (T1), 5% (T2) and 10% (T3) inclusion levels of Aloe vera respectively. The design of the experiment was a completely randomized design and the birds were fed for 42 days with their respective experimental diets. Records were kept on feed intake, body weight gain, feed conversion ratio and mortality trend to the end of the experiment. Results showed that there were significant differences (p<0.05) in weight gain and feed conversion ratio within treatment but no significant difference (p>0.05) on feed intake. Highest overall profit was obtained from the T2 group. The inclusion of Aloe vera at 5% level supports feed absorption and growth in cockerels. This can therefore be used as a good leaf protein concentrate in cockerel nutrition for improved productivity and therefore, profitability.

  Thirty-two large white x Hampshire weaner pigs aged 8-9 weeks with average weight of 18kg were used in a 56 day feeding trial to evaluate the effect of dietary inclusion levels of Ipomoea asarifolia Leaf Meal (IALM) on the haematology and serum biochemistry of weaner pigs. The pigs were separated into four groups and further replicated 4 times in a completely randomized design and fed diets containing 0, 5, 10 and 15% levels of IALM which represented treatments 1, 2, 3 and 4 respectively. The pigs were adequately housed, while feed and potable water were supplied ad libitum. Other standard management practices were adequately put in place. At the end of the 56 days, 4 pigs were randomly sampled from each treatment (1 per replicate) and blood collected through venepuncture on veins at backside of the ears. The samples were analyzed for haematology and serum biochemistry. All data were subjected to analysis of variance. Results show that most haemotological parameters were influenced by the varying levels of the treatment indicating significant differences (p<0.05) between treatments except for Hb and MCH. Also, white blood cell differentials significantly differed (p<0.05) between treatments. There were no deleterious effect on the haematology and serum biochemistry of growing pig.

  A 28-day feeding trial was conducted using 240 Anak 2000 strain of finisher broilers fed 0, 15, 30 and 45% levels of exogenous enzyme supplemented Bambara Seed Offal (esBSO) in a completely randomized design where esBSO replaced whole maize weight for weight. Each of four dietary treatments was further replicated four times. Routine vaccination and medication typical of broilers were strictly adhered to. The initial weight, final weight, weight gain, feed intake, feed conversion ratio, feed cost/kg and feed cost/weight gain were measured. Results show that birds on control (0%) and 15% esBSO with weight gains 1.73kg each, did not differ significantly (p>0.05) and were superior to those of levels 30 and 45% (1.55 and 1.43 kg respectively). Feed conversion ratio, feed cost/kg and feed cost/weight gain declined as the level of esBSO increased from 0-45%, with 0% having the best FCR.

  Sixty 5-week old Marshall broiler chicks were used in a 28-day feeding trial in a Completely Randomized Design, in a deep litter house to evaluate the effect of Chromolaena odorata Leaf Meal (COLM) on the growth performance of finisher broiler chicks. The chicks were grouped into four treatments having 0, 2.5, 5 and 7.5% COLM which were replicated thrice. Feed and water supply were ad libitum. Also medication, vaccination scrupulous sanitation, regular disinfection of the pens and other standard management practices were adopted. Initial weights of the birds, 633.00, 636.67, 630.00 and 585.67 g for treatments 0, 2.5, 5 and 7.5% COLM respectively did not vary significantly (p>0.05). However, significant differences (p<0.05) occurred between the final weights 2120,00, 2096.67, 2003.33 and 1506.67 g for treatments 0, 2.5, 5.0 and 7.5% COLM respectively. Daily weight gain, daily feed intake and feed conversion ratio, showed similar trends for birds on 0, 2.5 and 5.0% COLM which were similar in values (p>0.05) but differed significantly (p<0.05) from the values for birds on 7.5% COLM. Results confirmed that COLM could substitute soya bean as feed ingredient for broiler chicks up to 7.5% but 5.0% is optimal.
