  A total of 144 day-old Anak 2000 strain of broiler chicks were used in the study. A basal diet was formulated and supplemented at 0, 200, 400, 600 mg kg-1 of MgSO4 to constitute four dietary treatments. The birds were randomly allotted to the four dietary treatment groups and replicated thrice (12 birds per replicate). The performance characteristics, nutrient digestion coefficients, Mg utilization coefficients and haematological and biochemical parameters of the birds were determined. Feed conversion ratio, crude protein retention, Mg utilization and blood parameters were highest in birds fed diet containing 400 mg kg-1 MgSO4. There were significant (p<0.05) differences in the final body weight, weight gain, Feed Conversion Ratio (FCR), Protein Efficiency Ratio (PER) and crude protein retention. Liver Mg content, Mg intake and excretion increased significantly in a dosage dependent manner. Nutrients digestibility increased significantly as Mg levels increased from 0 to 400mg though, digestibility coefficients of Mg were significantly (p>0.05) depressed across treatments. However, serum Mg, Mg digestibility coefficient and tissue Mg residue were similar across treatment groups. The results showed that inclusion of 400 mg kg-1 supplemental MgSO4 in practical broiler starter diets resulted in improved performance and nutrients digestibility of the birds.

  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.

  Wet citrus pulp from sweet orange collected from a fruit juice canning factory at Ibadan, Oyo State, was sun-dried for 7 days on asphalt surface. Sixteen West African Dwarf goats weighing 5.0-5.6 kg were used in a 112 days feeding experiment to determine the effect of citrus pulp in the dry season feed of West African Dwarf goats placed on Enterolobium cyclocarpum as basal feed. The dried citrus pulp contained 6.3% crude protein, 17.63% crude fibre, 5.13% ash and 69.32% nitrogen free extractives on DM basis. Citrus seeds, collected separately, contained 11.69% CP, 8% CF, 5% ash and 69.44% NFE. A control diet with contained 88.5% Brewers’ Dried Grains (BDG) and 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 highest total nutrient intakes (p>0.05) occurred at 50% level of dried citrus pulp replacement being 593.19, 116.08, 59.78, 266.12, 182.86, 14.58, 150.26 and 83.26 gd-1 for DM, CP, CF, NDF, ADF, ADL, cellulose and hemicellulose, respectively. The digestibility coefficients of DM, CF, Ash, NFE, NDF, ADL, cellulose and hemicellulose increased with increasing levels of dried citrus pulp in the diets and were highest at 75% level of replacement. The inclusion of both citrus pulp and brewers’ dried grains in the diet at 50% levels is recommended as dry season feed for ruminant animals using E. cyclocarpum as basal feed.

  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. 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.

  A ten-weeks feeding trial was conducted to assess the effect of inclusion of Maize Milling Waste (MMW) with/without xylanase supplementation on the performance characteristics, nutrient digestibility, haematological traits and carcass characteristics of weaner rabbits. A total of 48 unsexed, crossbred weaner rabbits were randomly allotted to the experimental diet in a 2 x 4 factorial arrangement with MMW at graded levels (0, 12, 23 and 35%) and two xylanase levels (0 ppm, 100 ppm). There were eight treatment groups of six rabbits each per treatment group(3 replicate of 2 rabbits per replicate). The final live weight of the rabbit were significantly (p<0.05) affected by MMW inclusion levels and it decreases as inclusion level of MMW increases from T1 to T4 and T3 to T8 respectively. Xylanase inclusion has no effect and hence did not improve the feed intake, final weight or weight gain. Nitrogen retention and crude fibre digestibility were not significantly (p<0.05) affected by the treatment. Ash digestibility significantly (p<0.05) increases as the inclusion level increases. Carcass yield indicated that shrunk weight, empty carcass weight and head were significantly (p<0.05) affected by the treatment imposed. The empty carcass weight reduces with increase in MMW inclusion level from 1165.30 g to as low as 999.30 g T4. The same trend also applies for the xylanase supplemented diets. The haemoglobin, red blood cell, mean corpuscular volume and white blood cell were all significantly (p<0.05) affected by the treatment. The result indicated that above 12% MMW inclusion level may have adverse effect (with/without xylanase enzyme supplementation) on rabbit performance and nutrient utilization and may not be a promising energy supplement beyond inclusion level of 12% in a weaner’s diet.

  Twenty four hybrid weaner rabbits of both sexes were used to evaluate the usefulness of malted sorghum sprout. The rabbits were randomly allotted to four dietary groups of 6 rabbits and three replicates of 2 rabbits each. The MSP was incorporated into the diet at 0, 10, 20 and 30% levels. The experiment lasted for 56 days. Feed and water were supplied ad libitum. The performance characteristics, nutrient utilization, carcass characteristics and economics of production were measures of response. The result showed that, the final live weight and daily weight gain of rabbits on 0 and 20% MSP diets were highest (p<0.05). The daily feed intake of rabbits on MSP diets were significantly (p<0.05) lower than those on 0% MSP. The dry matter, crude protein and crude fibre digestibility significantly declined (p<0.05) as the level of MSP inclusion increases. Energy intake and energy retained followed a similar trend. Carcass weight, liver, kidney and heart weights were significantly (p<0.05) influenced by the dietary treatment. Less cost was incurred in producing a kilogram of rabbit when fed 20 and 30% MSP levels. 20% level of inclusion in rabbit diet could be of benefit in terms cost reduction and better growth.
