  An experiment was conducted to compare the performance of WAD goats fed Panicum maximum basal diet and concentrate supplements of Palm Kernel Cake (PKC), Soya Bean Meal (SBM), Cotton Seed Cake (CSC) and Brewers Dried Grain (BDG). 12 animals were randomized into four groups to represent four treatments and each treatment has three replicates. Each animal represents a replicate. The experiment lasted 10 weeks and followed by three weeks metabolic trial. During the experiment, feed intake, weight gain and digestibility of nutrients were estimated while feed conversion ratio and protein efficiency ratio were calculated. The results obtained placed animals on SBM on top (p<0.05) in all the parameters estimated. This was followed by animals on CSC while animals on BDG had the least performance. The Dry Matter Intake (DMI) and the Crude Protein Intake (CPI) increased from 486.50 and 60.46 in BDG to 546.72 and 91.56 gd-1 in SBM, respectively. Digestibility of Dry Matter (DM) and Crude Protein (CP) increased from 57.90 and 71.80 in BDG and PKC respectively to 70.02 and 86.74% in SBM. The weight gain and protein efficiency ratio increased from 19.83 and 0.33in BDG to 33.36 and 0.37 in SBM, respectively while feed conversion ratio reduced from 24.53 in BDG to 16.39 in SBM. It was therefore, concluded from the experiment that WAD goats utilized SBM better than CSC, PKC and BDG.

  A study was carried out to determine the intake and utilization of Mango leaf meal by growing rabbits. Twenty cross weaned rabbits of average weight 700 g were randomly assigned to the five iso-nitrogenous and iso-caloric diets in which wheat offal was substituted at 0, 25, 50, 75 and 100%. The results showed that rabbits weight reduced significantly (p<0.05) across the dietary treatments. Weight gain and feed intake were affected significantly (p<0.05) by the treatment imposed on the rabbits. Dry matter digestibility, ash and crude fibre digestibility were affected across the treatment. Carcass evaluation values were significantly influenced by the treatment except the kidney. The cost kg-1 diet (^) decreased significantly as the level of dietary inclusion of Mango leaf meal increased from 0 to 100%. At the end of the study the highest savings on feed to produce kg-1 was obtained in the group which consumed 100% mango leaf meal diet. This was closely followed by rabbits on 75, 50 and 25%. It was therefore concluded that Mango leaf meal can be fed to weaner rabbits up to 50% level without any adverse effect on performance variables.

  A study was conducted to investigate the effects of lasalocid on the performance of WAD sheep with a view to monitoring the feed intake, growth response, influence on digestion and optimum level of lasalocid inclusion in the diets of WAD sheep. Lasalocid was added to diets at four different levels of 0.00%, 0.01, 0.02 and 0.03% to represent the four treatments of the experiment. Experimental sheep weighing 13.48±0.95 kg were allowed to feed on the experimental diets for a period of 28 days before shifting to the next experimental diet in a cross over experimental design with each treatment replicated 8 times. Some blood parameters (Biochemical) total serum protein and serum urea and (Haemotological), packed cell volume and haemoglobin concentration as well as cost efficiency of including lasalocid in the feed were also monitored. Inclusion of lasalocid was found to enhance (p<0.05) weight gains, protein status of the experimental sheep as well as the cost efficiency in the experiment. 0.03% lasalocid inclusion level was the best and is therefore recommended in diets for WAD sheep.

  Sixteen West African Dwarf goats weighing 5.0-5.6 kg were used in an experiment that lasted 112 days to investigate the utilization of citrus pulp based diets and E. cyclocarpum by West African Dwarf (WAD) goats. A control diet which contained 88.5% Brewers’ Dried Grains (BDG) and the three experimental diets in which BDG was replaced by citrus pulp at 25, 50 and 75% levels in the experimental diets, respectively constituted the four treatments. The goats were divided into four treatment groups of four animals each. Each group of animals was then assigned to one of the four different experimental diets formulated. Significant growth rates (p<0.05) of 22.14-34.02 gd +1 were obtained with the highest growth rate recorded at 50% level of dried citrus pulp inclusion while the growth decreased with increasing levels of dried citrus pulp in the diets. Nitrogen intake (gd-1) decreased significantly (p<0.05) with increasing levels of dried citrus pulp in the diets from 45.57-33.28 and was lowest in the control diet. Nitrogen retention also followed similar trend, being highest (42.07 gd-1) at 25% level of dried citrus pulp replacement in the diet. The Packed cell volume, haemoglobin concentration, red blood cells, white blood cells and total blood protein were significantly (p<0.05) different across the dietary treatments at the start and end of the trial. The values for PCV, Hb, RBC, MCH, glucose and total protein decreased significantly (p<0.05) different in the control diet. Serum Glutamate Pyruvate Transaminase (SGPT) values also increased significantly (p<0.05) with increasing levels of dried citrus pulp in the diets at the end of the experiment and were highest (6.50 IU/L) at 75% level of citrus pulp. Therefore, the efficient utilization of citrus pulp and E. cyclocarpum by WAD goats was attained at the 50% level of inclusion in the diets.

  A study was conducted to investigate the effects of lasalocid on the performance of WAD sheep with a view to monitoring the feed intake, growth response, influence on digestion and optimum level of lasalocid inclusion in the diets of WAD sheep. Lasalocid was added to diets at four (4) different levels of 0.00, 0.01, 0.02 and 0.03% to represent the four treatments of the experiment. Experimental sheep weighing 13.48±0.95 kg were allowed to feed on the experimental diets for a period of 28 days before shifting to the next experimental diet in a cross over experimental design with each treatment replicated 8 times.

  Sixteen weaner rabbits of six weeks old, mixed breeds were fed Rice Milling waste based diets at 0, 25, 50 and 75% levels (replacing maize), respectively. This was done for a period of thirty-five days. The weight gain, feed conversion and protein efficiency ratios of rabbits fed 0% level and 25% level were significantly higher than those of rabbits fed 50 and 75% levels of the experimental diet. 0% and 25% levels do not have any significant difference between them. No mortality was recorded and also no physiological changes were observed throughout the thirty-five days of experiment. The nitrogen retention and crude fibre digestibility of diets fed 0% RMW and 25%RMW were significantly (p<0.05) the same and higher than others. Basically, from the performance data, there were no significance differences between the control diet 0% (RMW) and 25% (RMW) when compared, but there were significant differences when compared with diet 3 (50% RMW) and diet 4 (75% RMW), with diet 4 having the least performance. In terms of costing, diet 4 (75%) was the cheapest, but the least performance, while that of diet 2 (25% RMW) had a better performance and at a reduced cost. It can be concluded that RMW can conveniently be included in a weaner ration at 25% level of inclusion (replacing maize) without any adverse effect.
