A 28-day feeding trial was conducted to evaluate the effect of honey-flavoured diets on performance, nutrient retention, organ weights and economy of production. 0ne hundred and twenty 4-weeks old 'Anak 2000' broiler chicks were randomly allotted to four treatments, replicated three times with 10 birds each in a completely randomized design (CRD). Four diets were formulated such that diet 1(0%) contained no honey and served as the control, while diets 2, 3 and 4 contained 0.5, 1.0 and 1.5% honey-flavour, respectively. The results showed that diet 4 containing 1.5% honey flavour significantly (P < 0.05) improved the final body weight (1977g), weight gain (1327g), daily weight gain (47.29), feed/gain (2.18) and protein efficiency ratio (2.16) than broiler fed other diets including the control. Broilers on the control diet had the least values of body weight gain (1754g), weight gain (1104g), daily weight gain (39.43g), worst feed/gain (2.59) and protein efficiency ratio (1.80). Broilers fed diet 4 had the highest (P<0.05) nutrient retention of protein (83.80 %), ether extract (86.80 %) and crude fibre (70.50%) while broilers on the control diet had the lowest retention values of protein (65.20%), crude fibre (63.30%) and ether extract (73.70%). The dry matter retentions were similar across the treatments with highest numerical values of 82.80% recorded by birds on diet 4 and least value of 78.80% on diet 1(control). The liver, heart, lungs, kidney and caecum weights did not differ significantly (P>0.05) across the treatments but were numerically higher with increased in the honey-flavoured diets. The gizzard and caecum weights were significantly (P<0.05) increased with increase in honey flavoured diets. Cost per kg feed increased as the level of honey-flavoured inclusion in the diets increased 1.5 % with value of ? 58.00/kg compared to the control diet with ? 47.01/kg while the revenue generated showed that birds fed diet 4 (1.5% honey) were the most economical to produce with value of ? 597.15/bird compared with those on the control (₦ 496.80/bird). Addition of honey at 1.5% demonstrated superiority in this study with no adverse effect on bird's performance and organ.

The performance and nutrient retention of broilers fed raw (RMD), toasted (TMD), boiled (BMD), soaked and boiled (SMD) or no (NMD) Mucuna cochinchinensis seed diets at both starter and finisher phases were assessed using 400 broiler chicks. The birds were fed a common proprietary feed (Top Feed) until 2 weeks of age, followed by a treatment diet for 3 weeks of the starter period, then 5 weeks on the finisher diet. At the starter phase, RMD significantly (P < 0.05) decreased liveweight, daily weight gain, protein efficiency ratio and encouraged poorer feed conversion ratio and higher cost per kilogram weight gain when compared with other diets. TMD decreased (P < 0.05) only the protein efficiency ratio. RMD also decreased (P < 0.05) retention of dry matter (DM), crude protein (CP), crude fibre (CF) and energy while TMD decreased (P < 0.05) retention of only DM, CP, and energy. At the finisher phase, RMD also significantly (P < 0.05) decreased daily weight gain, protein efficiency ratio and feed conversion ratio and increased cost per kg weight gain, while TMD decreased (P < 0.05) only the protein efficiency ratio and feed conversion ratio. RMD again decreased (P < 0.05) retention of DM, CP, CF and energy, while TMD, as in the starter phase, again decreased (P < 0.05) retention of DM, CP and energy. On a cumulative basis, RMD adversely affected (P < 0.05) all the parameters under investigation. TMD affected (P < 0.05) only the feed conversion ratio, protein efficiency ratio and cost per kg weight gain. Boiling Mucuna cochinchinensis, therefore, encourages significantly better performance of chicks, higher nutrient retention and lower cost per kg weight gain than toasting, whereas soaking before boiling does not add any advantage to boiling alone.

The study was carried out to determine the effect of Daniellia oliveri leaf meal (DOLM) in complete diets on feed intake, digestibility, nitrogen utilization and growth of Savannah Brown goats in a 90-day trial using the completely randomized design. Thirty-six does, with an average initial weight of 10.66 kg, were randomly divided into four groups of similar body weight (BW) and allocated to one of the four complete diets with DOLM inclusion levels at 0%, 20%, 30% and 40% respectively. Intakes of dry matter (DM) and organic matter (OM), and cost/kg BW gain were higher (p<0.05) in the control diet than in the treatment diets. Intake of crude protein (CP) was higher (p<0.05) for the control diet compared to the 30 and 40% DOLM diets. Feed conversion ratio and faecal nitrogen excretion of animals on 20% DOLM diet were lower (p<0.05) than other diets. Final body weight, total weight gain and average daily weight gain were not (p>0.05) affected by the diets. Digestibility of DM and CP, and nitrogen balance of animals on 0 and 20% DOLM diets were higher than those on 30 and 40% DOLM. Digestibility of OM and crude fibre was lowest (p<0.05) for the control diet relative to other diets. Nitrogen intakes (NI) of 0 and 40% DOLM diets were lower (p<0.05) compared to those of 20 and 30% DOLM diets. Nitrogen absorbed (NA) and nitrogen retention (as % of NA) were marginal (p<0.05) for 30% DOLM diet relative to other diets Nitrogen retention (as % of NI) was highest and lowest (p<0.05) for 20%DOLM diet, and 30 and 40% DOLM diets respectively. The study shows that Daniellia oliveri leaf meal can be used up to 40% inclusion level to replace 100% of maize offal in the diet of Savannah Brown goats without adversely affecting the performance of the animals.

An eight weeks feeding trial was conducted to assess the effect of feeding graded level of soaked pigeon pea meal (SPPM) in wood ash extract or solution on the growth performance, haematological and serum biochemical indices of broiler chickens. A total of 144 day-old chicks (Anak 2000) were randomly allotted to four treatment diets (1, 2, 3 and 4) in a completely randomized design. Each treatment group was replicated three times with twelve birds per replicate, thus, having thirty-six chicks per treatment group. Diet 1 contained 0% SPPM in wood ash extract for 72hours as the control diet, while diets 2, 3 and 4 were formulated to contain 25, 50 and 75% inclusions of SPPM in place of soybean meal. Results showed that the average live weight, daily weight gain and feed intake as well as protein efficiency ratio were significantly (P<0.05) influenced by the dietary treatments at the finisher phase. Broiler chickens fed 25% SPPM based diet had a higher (P<0.05) and comparable value of live weight, weight gain and protein efficiency ratio to that recorded in the control diet at the finisher phase. The haematological and serum biochemical indices revealed that albumin and total cholesterol were significantly (P<0.05) influenced by the treatment diets. The albumin value (2.2g/dl) was highest in birds fed 50% SPPM, whereas, the cholesterol value decreased (P<0.05) with increasing levels of inclusion of SPPM from 0 to 75%. It therefore implies that SPPM can be partially included in broiler diets up to 25% level with optimum growth performance and without any detrimental effect on the blood profile of broiler chickens.

The effect of graded levels of raw bambara nut (Voandzeia subterranea L) waste on nutrient intake, digestibility and utilization by weaner rabbits was investigated. Four diets were formulated to contain 0, 10, 20 and 30% raw bambara nut waste (RBW). Twenty-four hybrid (Chinchilla x New Zealand white) weaner rabbits weighing 790-880g at six weeks were randomly divided into four groups of6 rabbits each. The groups were randomly assigned to the four diets in a completely randomized design (CRD) for 56 days. Each treatment was replicated 3 times with two rabbits per replicate. Results showed that significant differences (P<0.05) existed among treatments in final body weight (FBW), average daily weight gain (4DWG) and intake of dry matter (DM), crude protein (CP), gross energy (GE) and digestible energy (DE). There were also significant differences (P<0.05) among treatments in digestibility coefficients of DM, CP crude fibre (CF), ether extract (EE) and nitrogen free extract (NFE), Rabbits fed 20 and 30% RBW diets had significantly (P<0.05) lower FBW and ADGW, and lower (P<0.05) intake of DM, CP GE and DE than rabbits fed the control diet. Rabbits fed 20 and 30% RBW diets also had significantly (P<0.05) lower digestibility coefficients of DM, CP CF, EE and NFE Results showed that nutrient intake, weight gain and digestibility coefficients were depressed. Mortality was observed at 20 and 30% RBW levels. Although there were no significant differences (P>0.05) among treatments in relative organ weights and in carcass dressing percentage, the kidney of rabbits fed 30% RBW diets had mild degeneration necrosis and dilatation of the tubules. Bile duct dilatation, hyperplasia of the bile duct epithelia cells. fibrosis and thickening of the interlobular septa were observed in the liver of rabbits fed 30% RBW diets. The depression in nutrient intake, and weight gain, and the observed histopathological changes at 20 and 30% RBW levels could be due to ant nutritional factors present in the raw bambara nut waste or done to high fibre levels of RBW The results indicate that up to 10% RBH can be included in the diets of weaner rabbits without serious deleterious effects on rabbits

The effects of different dietary levels of toasted bambara groundnut (Voandzeia subterranea L) waste on the performance of growing rabbits was studied. Twenty-four, 6-7 weeks old cross bred (Chinchilla x New Zealand whitel rabbits with average initial weight of 9629 were used for the feeding trial which lasted for 8 weeks. The rabbits were randomly divided into four treatment groups of 6 rabbits each and fed diets containing 0% (control), 10, 20 and 30% toasted bambara groundnut waste (TBGW) using a completely randomized design (CRD). Dry matter, crude protein, crude fibre, ether extract and nitrogen-free extract intake and digestibility, weight gain and economics of TBGW inclusion were determined. Proximate composition of the diets, faeces, raw and toasted samples were also determined. The raw and toasted bambara groundnut waste had 91 and 93% dry matter, 17.0 and 16.27% crude protein, 26 und 24% crude fibre, 5 and 3. 5% ether extract, 2.5 and 4.0% ash, 40.5 and 45.23% nitrogen-free extract, and 4.13 and 3.88 kcal/g energy respectively. Significant differences (P<0.05) existed between treatments in feed intake, weight gain, final body weight, and digestibility of dry matter. crude protein, crude fibre and nitrogen free extract. Feed intake, weight gain, final body weight, and digestibility of dry matter, crude protein and nitrogen-free extract were similar for the control and 30% TBGW diets, and these were significantly (P<0.05) lower than that for 10% TBGW diet. The feed cost AN/kg gain) was similar for 10, 20 and 30% TBGW diets. The result showed that up to 30% toasted bambara groundnut waste can be included in the diets of growing rabbits without any adverse effect on performance.

AbstractExperiments were carried out to establish the suitability of full fat neem seed meal (FFNSM) in broiler and growing rabbit diets. In the broiler experiment, 200-day-old (Babcock) broiler chicks were used in a 10-week trial, with the FFNSM fixed at 0 (control), 25, 50, 75 and 100 g/kg diet. In the rabbit experiment 24 rabbits of three different breeds were used in an 8-week trial, with the FFNSM fixed at 0 (control), 100, 200 and 300 g/kg diet. The criteria of response were food intake, weight gain, food conversion and protein efficiency ratio and mortality. There was a significant (P < 0·05) negative correlation between the dietary inclusion of FFNSM, weight gain and food conversion efficiency of the birds in the starter phase. In the finisher phase from 5 to 10 weeks, food intake, weight gain, food conversion and protein efficiency ratio did not differ significantly (P > 0·05) between the birds on the control diet and diets containing up to 75 g FFNSM per kg. For all the measurements, rabbits on the diet with 100 g FFNSM per kg gave better results than the control. Food intake, weight gain, food conversion efficiency and protein efficiency ratio did not differ significantly (P > 0·05) between rabbits on control diet and the diet containing 200 g FFNSM per kg. Performance on the diet with 300 g FFNSM per kg was poorest.

Ninety-nine, 28 day-old broilers were used to investigate the effect of raw and roasted Afzelia Africana seed meal (AASM) on performance, apparent nutrient digestibility and nitrogen retention and cost of broiler production under deep litter system of management for 35 days in the finisher phase. The birds were allotted to three treatments with 33 birds. Each treatment was replicated three times (11 birds per replicate). The data collected were feed intake and body weight gain. Protein efficiency ratio (PER), feed conversion ratio (FCR) and apparent nutrient digestibility were also calculated. The results obtained revealed that chicks fed control (A) diet were significantly (P<0.05) higher in weight gain and feed intake than others. Superior (P<0.05) feed conversion ratio (FCR), protein efficiency ratio (PER), daily feed cost and feed cost per kg weight gain were obtained in roasted dehulled AASM(C) diet when compared to the control and raw AASM diets. The apparent nutrient digestibility of dry matter, crude protein, crude fibre, ash, nitrogen free extract and nitrogen retention of roasted diet compared favourably with that of the control diet. The row AASM (B) diet depressed performance and nutrient retention values. The cost per kg diet and cost per live weight gain reduced significantly (P<P.05) in AASM based diets when compared to the control diet. However, the control diet significantly (P<0.05) increased the revenue generated and gross profit when compared to AASM based diets. Based on the results of this study, it is recommended that higher levels of roasted AASM may have some benefits.

A 56-day feeding trial using twelve (12) crossbred weaner pigs of 8 weeks of age and average weight of 10.58±17kg were used to investigate the effect of different dietary levels of raw bambara groundnut offal on their growth and carcass characteristics. Four diets were formulated to contain raw bambara groundnut offal at 0, 10, 20 and 30%, designated T1, T2, T3 and T4 respectively. The weaner pigs were randomly assigned to the four (4) diets in a completely randomized design (CRD) experiment. Chemical composition of the test ingredient and diets were analysed. Data collected include feed intake, weight gain, feed conversion ratio (FCR), protein efficiency ratio (PER) and economics of production. The carcass characteristics were also evaluated. The proximate composition of the experimental diets revealed that the crude protein and ether extract contents of the diets decreased with increased levels of raw BGO in the diets, but the converse was true for crude fibre and ash contents. The results indicated significant differences (p< 0.05) in daily weight gain (DWG). feed conversion ratio, protein efficiency ratio, cost (N) /kg of seed and cost (N)/kg weight gain. The values were. 0.34, 0.29, 0.28 and 0.22kg for DWG, 3.03, 3.62, 3.55 and 4.30 for FCR in T1, T2, T3 and T4 respectively. Protein efficiency ratio, values were 1.84, 1.54, 1.57 and 1.29. Cost/kg of feed values were 75.69, 70.13, 64.56 and 56.10, and cost (N)/kg weight gain were 229.32, 253.86, 229.20 and 253.69 for the treatments respectively. The results of the carcass evaluation indicated significant differences (p< 0.05) for ham and trotters. The values were 0.31, 0.35, 0.37 and 0.32 for ham in T1, T2, T3 and T4 respectively. The values of trotters were, 64.6.56.99, 56.98 and 53.66 among the treatments. For organs characteristics, the results indicated significant differences (p< 0.05) for lung, kidney, liver and spleen. The values of the lungs were, 11.20. 11.25. 9.40 and 8.97 among the treatments. The values of kidney and liver were, 3.34, 2.86, 3.72 and 3.14, and 24.28, 28.57, 22.55 and 27.70 respectively. The inclusion of up to 20% raw BGO in the diet of weaner pigs recorded comparable daily weight gain, feed conversion ratio and cost/kg weight gain with the group fed the control (0%raw BGO). Further studies involving heat treatment of the BGO might be necessary to improved nutrient utilization by the animals, and also increase inclusion level.

Fish is used as a great source of food and the quality of its meat can be indicated by fat and protein contents as well as low quantity of water in fish meat. Therefore, the present study was performed for improvement in weight, feed-conversion ratio, protein-efficiency ratio, and growth. The experiment was performed at commercial level in field (pond) and the influence of fish meal protein on growth of Labeo rohita was investigated in 60 days culture trials. 90 fingerlings (Size: 4.97 to 6.04; Weight: 4.15 to 4.20) were maintained in well aerated 280 L three glass tanks in triplicate. These glass tanks were named as T1, T2 and T3. T1 was consisted of 30% crude protein with control diet containing proteins, fats vitamins and fibres, T2 consisted of 35% protein with control diet, while T3 consisted of only control diet (rice polish). The fish were fed 4% percent of their body weight twice a day at twelve hours interval for 60 days. There was a significant increase (p<0.05) in body weight, feed-conversion ratio, protein-efficiency ratio, and gross fish production of fish having 35% fish meal protein with control diet (T2) when compared with 30% fish meal protein with control diet T1 and control diet T3. These findings suggest that 35% fishmeal protein appear to be sufficient for obtaining optimum growth in fish.
