A 91 day feeding trial was conducted using twenty (20) weaned heterogeneous breed rabbits of both sexes with initial weight of 225g–500g to evaluate the replacement value of maize for composite cassava meal (CCM) in diet. Five experimental diets were formulated such that the control diet represented as treatment 1(T1) contained 100% maize as the major energy source in the diet. CCM replaced 25, 50, 75 and 100% of maize in the other treatments (T2, T3, T4 and T5 respectively). The rabbits were divided into five treatments of four rabbits each and randomly assigned to the five diets in a completely randomized design with each rabbit serving as replicate. Data collected included weight gain and feed intake, while feed conversion ratio and economics of production were computed. The result revealed that the crude protein (17.78-16.26%) and ether extract (6.79-5.93) content of the diet decreases as level of CCM increased in the diets while crude fibre (12.67-13.88%) content increased with increased level of CCM in the diet. The nutrient compositions of the experimental diets were within acceptable ranges for growing rabbits. The final weight and the total weight gain were not affected by treatment but feed intake significantly increased as the level of replacement increased indicating enhanced acceptability due to CCM in diet. Daily weight gain was also enhanced as the level of replacement of CCM for maize increased. The cost of feed per kg was reduced but the total cost of feeding was increased as the level of replacement increased. The cost of production was minimized and profit was maximized at 100%, when 100% of the maize was replaced by CCM. CCM has no harmful effect on performance of rabbits and the replacement of maize with CCM in diet has reduce the cost of feed per kilogram and maximize profit at 100% level of replacement. Farmers can include composite cassava meal in diet of rabbits to replace 100% of maize as major source of energy in diet.

Shea nut meal is a by-product that is cheaper than maize though its replacement value for min rabbit diet is not yet determined. It is however, hoped that the use of shea nut meal in diet would reduce the cost of production and increase profit. A twelve-week trial was therefore conducted to determine the replacement value of shea nut meal (SNM) for dietary maize on growth performance and economics of production of rabbits. Forty rabbits were divided into five, replicated eight times and allotted to five dietary treatments in a completely randomized design. Diet 1 had maize as major energy source and without SNM, while in diet 2, 3, 4 and 5, SNM replaced maize at 25, 50, 75 and 100% respectively. Proximate composition of SNM, feed intake, weight gain, feed cost, cost of production, revenue and profit were determined. The study revealed that SNM has 16.83 % ether extract (EE) and 46.66 % nitrogen free extract (NFE), low in crude fibre (CF) and 8.74% crude protein (CP). Daily feed intake was higher (p<0.05) for rabbits fed control (65.79g/day) than those fed the test diets (50.90- 60.10g/day). Rabbits fed control diet gained similar (p>0.05) weight as those fed diets 2 or 3, but higher (p<0.05) than those fed diets 4 or 5. Feed gain ratio by rabbit were similar (p>0.05) except rabbits fed diet 5 which were significantly less. Cost per kg diet decreased (p<0.05) as level of replacement increased, and the control diet cost (N 88.75) more than any (N 72.77 - N 84.76) of the test diets. Cost of feeding and total cost of production were reduced (p<0.05) by 16.86 – 36.55% due to replacement. The cost to gain a kg of weight was similar (p>0.05) for each of diets 1 to 4 but significantly (p<0.05) less than that of diet 5. The gross margin was lesser when SNM replaced maize in diets at 100%. Replacement of maize with SNM in diets up to 75% has no negative effect of growth performance and economics of production, however, at 100% replacement levels; there was a decreased feed intake, increased cost per kg weight gain, and a reduced gross margin.

The feeding value of melon (Citrulus vulgaris) seed offal (MSO) was determined in a 12-week feeding trial using 25 six weeks old male rabbits with an average initial weight of 485g. The animals were fed diets containing 0,7.5, 15, 22.5 and 30% MSO in a completely randomized design (CRD). Digestibility trial and economic benefits of using the test material were carried out. Data obtained were subjected to analysis of variance (ANOVA) and differences between means were also determine. Results obtained showed no significant (P>0.05) treatment effects on daily weight gain (DWG), daily feed intake (DFI) and feed conversion ratio (FCR). The cost of feeding diets 1 and 2 was significantly (P<0.05) higher (A$152.34 and N157.20) than for diets 4 and 5 (AL143.53 and N135.56). The cost generally decreased from N152.34- N135.56 with increase in the level of MSO in the diets. The digestibilities of dry matter (DM), crude protein (CP) and ether extract (EE) were significantly (P<0.05) affected by increase in the levels of MSO in the diets. DM and CP digestibilities were significantly (P<0.05) higher at 15 and 30% MSO levels when compared with the control and other MSO levels. MSO inclusion in the diets significantly (P<0.05) improved EE digestibility above that of control diet but EE digestibility did not differ significantly (P> 0.05) among diets containing MSO. Crude fibre (CF) and Nitrogen free extract (NFE) digestibilities were similar (P>0.05) for all the diets. It can be concluded that MSO could be used up to 100% replacement for RO in rabbit diets.

This study was carried out to investigate the performance of broilers fed graded levels of Dry Distilled Cassava with Soluble (DDCS). In a 28-day trial, one hundred and forty-four (144), 5-week old, un-sexed Arbor acre strain broiler chicks (average weight of 1.09±0.02 kg) were randomly allocated to four dietary treatments of wheat offal (WO) and DDCS (12% WO + 0% DDCS = 0% DDCS; 8% WO + 4% DDCS = 4% DDCS; 4% WO + 8% DDCS = 8% DDCS and 0% WO + 12% DDCS = 12% DDCS) in completely randomized design. Each treatment had 2 replicates of 18 birds each. Dry matter feed intake (FI g/day), daily weight gain (g/day) and total weight gain (kg) decreases with increase in the levels of DDCS, while the feed conversion ratio (FCR) increases with increase in levels of DDCS, respectively. However, there was no significant (P>0.05) differences in the carcass evaluation measured. It was concluded that DDCS could replace wheat offal in the diets of broilers up to 8% without significant difference in growth and feed intake without detrimental effects on carcass quality of the birds.     Cette étude a été réalisée pour étudier la performance des poulets de chair nourris à des niveaux échelonnés de manioc distillé sec avec soluble (le 'DDCS'). Dans un essai de 28 jours, cent quarante-quatre (144) poussins de chair de la souche Arbor acre non sexés de 5 semaines (poids moyen de 1.09 ± 0.02 kg) ont été répartis au hasard dans quatre traitements diététiques d'abats de blé (WO) et DDCS (12% WO + 0% DDCS = 0% DDCS ; 8% WO + 4% DDCS = 4% DDCS ; 4% WO + 8% DDCS = 8% DDCS et 0% WO + 12% DDCS = 12 % DDCS) dans une conception complètement aléatoire. Chaque traitement comportait 2 répétitions de 18 oiseaux chacun. L'apport alimentaire en matière sèche (FI g / jour), le gain de poids quotidien (g / jour) et le gain de poids total (kg) diminuent avec l'augmentation des niveaux de DDCS, tandis que le taux de conversion alimentaire (FCR) augmente avec l'augmentation des niveaux de DDCS, respectivement. Cependant, il n'y avait aucune différence significative (P> 0.05) dans l'évaluation de la carcasse mesurée. Il a été conclu que le DDCS pouvait remplacer les abats de blé dans l'alimentation des poulets de chair jusqu'à 8% sans différence significative de croissance et de consommation alimentaire sans effets néfastes sur la qualité de la carcasse des oiseaux.

The effect of forage to concentrate ratios on the performance of weaner rabbits was investigated using twenty (20) weaner rabbits. They were randomly assigned to five treatment diets/with two replicates of two (2) rabbits per pen in a completely randomized design CRD). The experiment lasted for 56 days. Ti = forage 80%: concentrate 20%, T2 = forage 60%. concentrate 40%, T3 = forage 40%: concentrate 60%, T4 = forage 20%: concentrate 80% and T5 = forage 50%: concentrate 50% served as the control. Data were collected for feed intake, weight gain, carcass quality and the economics of the diet. The growth performance result was significantly different (p<0.05) for all the parameters considered except for total feed intake. Treatment 3 (T3) had the highest value for final weight (1423.0 g), total weight gain (925.5g) and daily weight gain (16.52 g), with the least feed conversion ratio of (2.58) among others. The cut parts results showed that there was significant difference (p<0.05) for all the parameters considered. 73 also had the highest value for the prime parts. The organ weights results did not follow any specific pattern that could be attributed to the effect of the test ingredients. The economics /gross margin showed that T3 was favoured among others A 731.38, N929.18, N1045.78, N828.81, N825.39),T3 (forage40%: concentrate 60%) was therefore recommended.

The purpose of this study was to evaluate the performance, carcass, meat and economic viability characteristics of pigs fed Brazilian coproducts of corn ethanol production. A total of 40 finishing pigs were subjected to four levels of distillers dried grains with solubles (DDGS; 0, 100, 200, or 300 g kg-1) for 28 days, and body weight, daily feed intake, daily weight gain and feed conversion were measured. After slaughter, the carcass yield, fat thickness, loin eye area, the depth and perimeter of the loin eye, and the pH and temperature at 45 min and 24 h post-mortem, along with the drip loss and color of the Longissimus lumborum were evaluated. The economic viability of the diets was calculated. The inclusion of DDGS showed a quadratic effect on daily feed intake over 0-14 days. Pigs fed with 300 g kg-1 of DDGS showed worse feed conversion than those fed the control diet over 0-7, 0-14 and 0-21 days. The a* color parameter of the meat decreased linearly with increasing DDGS concentration but the other carcass and meat characteristics were not affected. Inclusion of 184.1 g kg-1 of DDGS showed the best economic viability, considering the cost of weight gain. DDGS may be included in pig diets up to 200 g kg-1 without affecting the performance or carcass and meat characteristics, while 300 g kg-1 compromises feed conversion.

This paper aimed to evaluate the metabolizability, performance and economic viability of purified glycerin inclusion in balanced diets fed to chicken broilers from 8 to 21 days old. Two experiments were conducted. In the first experiment, 100 broilers (14 days old) were distributed in a completely randomized design into two treatments, with five replications of 10 broilers. Treatments consisted of a control diet and a test diet, in which purified glycerin replaced 10% of the control diet. In the second experiment, 200 broilers (8 days old) were distributed in a completely randomized design into four treatments (0, 2, 4 and 6% of purified glycerin inclusion), with five replications of 10 broilers. The weight gain, feed intake, feed conversion, final weight, apparent metabolizable energy (AME), nitrogen-corrected apparent metabolizable energy (AMEn), metabolizability coefficients of dry matter (DMMC), crude protein (CPMC) and gross energy (GEMC), and the cost of feed per kg of broiler produced were evaluated. The AME, AMEn, DMMC, CPMC and GEMC from the purified glycerin were 3790 and 3560 kcal/kg, and 83.72, 71.52 and 86.27%, respectively. The glycerin levels did not affect (p>0.05) any of the performance characteristics (weight gain, feed intake, feed conversion and final weight). The lowest feeding cost and the highest gross margin were obtained for broilers fed with 6% purified glycerin. The inclusion of 6% purified glycerin in balanced diets for broilers from 8 to 21 days old was technically and economically feasible.

Considering the inherent attributes of cocoyam tuber meal (Xanthosoma Sagitifolium), its appropriate utilization for chicken diets may enhance performance of broiler chicken. This studywas therefore carried out to determine the nutritional evaluation of fermented cocoyam tuber meal as energy source in the diets of starter broilers production. The fermented cocoyam was used to replace maize at various levels to determine the best replacement would give optimal performance in starter broilers diets. One hundred and fifty 150 day old Agrited starter broilers were used for this experiment,. The proximate composition of fermented cocoyam tuber meal (FCYM) showed that it contained 19.5% moisture, 1.30% ash, 3.56% Crude protein, 5.30% crude fibre, 1.9% ether extract and 25.48% NFE. In the starter feeding trial, the fermented cocoyam was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each starter diet was fed to a group of 30 broilers chicks for four weeks using completely randomized design. Each treatment was divided into three replicates of 10 broiler chicks each. Parameters measured include initial body weight, final body weight, body weight gain, feed intake, feed conversion ratio and cost of production. In the starter feeding trial, the starter broilers on 25% FCYM compared favorably with those on the control diet (P>0.05) in terms of feed intake, feed conversion ratio and body weight gain and hence recorded the higher body weight gain. The cost per kg feed produced was N182.50 for the control diet and the lowest was diet 5 (100% FCYM) which was N82.74. The cost of production (cost/kg feed x feed conversion ratio) of starter broilers per kg body weight gain was lowest for diet 5 (100% FCYM) (N158.86), while the costliest was those on the control diet (N383.25). The results of the trial have shown that fermentation of cocoyam tuber meal for 4 days for formulating starter broiler diets was quite an effective method of processing because fermentation reduced the anti-nutrients content. It was concluded that fermented cocoyam tuber meal could be used in the diets of starter broilers up to 25% without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

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

Effect Of Feeding

An experiment was conducted to evaluate the comparative effect of feeding sundried sweet potato and its whole meal to weaner rabbits. The proximate analysis conducted revealed that sundried sweet potato meal and whole sundried sweet potato meal samples were rather low in protein contents as compared to maize. Twenty seven Weaner rabbits averaging 0.35kg were randomly allotted to 3 treatment groups in a completely randomized design. Each treatment group was replicated 3 times. Sundried Sweet potato meal and its whole meal replaced maize at 20% inclusion level. Treatments 1, 2, and 3 contained the control, sundried sweet potato meal (SSPM) and whole sundried sweet potato meal (WSSPM) respectively at 20% levels of inclusion. The weaner rabbits were fed ad-libitum throughout the experimental period. Significant differences (p<0.05) were observed for growth performance of the rabbits in average daily weight gain, average daily feed intake and feed conversion ratio in the weaner rabbits using sundried sweet potato and its whole meal. The values of mean daily weight gain ranged from 16.33g in treatment 2 (SSPM) to 18.47g in treatment 1 (control). Treatment 3 (WSSPM) gave a higher value that is comparable (p>0.05) to that of the control diet but better (p<0.05) than that of treatment 3 (SSPM). The values of average daily feed intake also ranged from 43g in treatment 2 (SSPM) to 50g in treatment 1 (control). WSSPM was consumed more than (p<0.05) than the SSPM which however influenced the cost of total feed consumed. Moreover, the values of feed conversion ratio (FCR) ranged from 2.54 in treatment 3 (WSSPM) to 2.70 in treatment 1 (control). Significant differences (p<0.05) were also observed in bio-economics of production of weaner rabbits using the test diets. The cost per kg feed, cost of total feed consumed per rabbit, cost per kg weight gain and revenue of the rabbits fed the test diets were significantly lower than the control diet however, the cost per kg weight gain was lower (p<0.05) for treatment 3 (WSSPM). For gross margin, WSSPM value was significantly higher (p<0.05) than SSPM value and the control diet. It was concluded that whole sundried sweet potato meal can be a good feed ingredient in rabbit diet.
