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

In a 56-day feeding trial, an experiment was conducted to determine the effects of replacing maize with different levels of ensiled cassava root-leaf blends (ECRLB) on growth, carcass yield, blood profile and economics of production of weaner rabbits. Five experimental diets were formulated and fed to the animals; diet 1= a maize based diet (control diet), diet 2= 30% maize + 10% ECRLB, diet 3 = 20% maize + 20% ECRLB, diet 4= 10 % maize + 30% ECRLB, diet 5= 40% ECRLB. A total number of forty weaner rabbits with an initial average weight of 574.09g±20.03g were randomly allocated to the five dietary treatments in a completely randomized design (CRD) with eight animals per treatment. Data were collected on growth indices, economics of production, carcass characteristics and blood profile Increased (P<0.05) weight gain was observed as the percentage inclusion of ECRLB increased. Rabbits on diet 4 (10 % maize + 30% ECRLB) and 5 (40% ECRLB) recorded the highest (P<0.05) daily weight gain with a corresponding highest (P<0.5) final body weight. Similar FCR were recorded across the treatments Economics of production of animals on diets containing 30 and 40% ECRLB was the best (P<0.05). Carcass indices were not significantly (P>0.0) affected by the experimental diets. Rabbits fed ECRLB recorded lower (P<0.05) serum cholesterol and higher (P<0.05) serum glucose concentration compared to control. In conclusion dietary inclusion of ECRLB up to 40% improved performance and did not show any deleterious effects on all indices examined and is recommended.     Au cours d'un essai d'alimentation de 56 jours, une expérience a été menée pour déterminer les effets du remplacement du maïs par différents niveaux de mélanges racines-feuilles de manioc ensilées (le 'ECRLB) sur la croissance, le rendement de carcasses, le profil sanguin et l'économie de la production de lapins sevrés. Cinq régimes expérimentaux ont été formulés et nourris aux animaux ; régime 1= régime à base de maïs (régime de contrôle), régime 2= 30% maïs + 10% ECRLB, régime 3 = 20% maïs + 20% ECRLB, régime 4= 10% maïs + 30% ECRLB, régime 5= 40% ECRLB. Un nombre total de quarante lapins sevrés d'un poids moyen initial de 574,09 g±20,03 g ont été attribués au hasard aux cinq traitements diététiques dans une conception complètement randomisée (CRD) avec huit animaux par traitement. Des données ont été recueillies sur les indices de croissance, l'économie de la production, les caractéristiques de la carcasse et le profil sanguin. Le gain de poids accru (P<0,05) a été observé à mesure que l'inclusion en pourcentage de l'ECRLB augmentait. Les lapins de l'alimentation 4 (10 % de maïs + 30 % d'ECRLB) et 5 (40 % d'ECRLB) ont enregistré le gain de poids quotidien le plus élevé (P<0,05) avec un poids corporel final correspondant le plus élevé (P<0,5). Les 'FCR' similaires ont été enregistrés à travers les traitements Économie de la production d'animaux sur les régimes contenant 30 et 40% ECRLB a été le meilleur (P<0,05). Les Indices carcasse n'étaient pas significativement (P>0,0) affectés par les régimes expérimentaux. Les lapins nourris à l'ECRLB ont enregistré un taux de cholestérol sérique inférieur (P<0,05) et une concentration plus élevée de glucose sérique (P<0,05) par rapport au contrôle. En conclusion, l'inclusion alimentaire de l'ECRLB jusqu'à 40 % a amélioré les performances et n'a pas montré d'effets délétères sur tous les indices examinés et est recommandée.

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.

The effect of diets containing 0% of wheat bran levels (control buffel grass and cactus pear) contrasted with diets with cactus pear as the only forage source and wheat bran levels (30; 37 and 44%) on nutrient digestibility, feed intake, animal performance, carcass characteristics, and economic analysis was evaluated. Twenty-eight male, non-castrated crossbred lambs (22.6 ± 2.37 kg) were submitted to confinement for 62 days. A completely randomized design was used with four treatments and seven repetitions. Four diets were formulated considering an intended mean daily weight gain of 200 g/animal/day. Means were compared by contrasts using Dunnett test at 5%. Animals fed cactus pear as the only roughage source (diets with 30; 37, and 44% of wheat bran) had lower dry matter intake and nutrient intake, Average Dairy Gain, and total weight gain than animals fed the control diet. Final body weight and slaughter weight of animals fed 44% of wheat bran was similar to the animals fed the control diet. Hot and cold carcass yields were higher in animals fed cactus pear and 30 and 37% of wheat bran. Feeding costs were lower when cactus pear was used as the only roughage source associated with wheat bran and consequently profit was greater. The use of cactus pear as the only roughage source associated with up to 44% of wheat bran is a viable alternative of the diet to confined lambs without modifying carcass characteristics with greater cost:benefit ratio.

The Cost

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.

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.

An experiment was conducted to evaluate efficacy of Lacto acidophilus on the growth performance, carcass characteristics and nutrient digestibility of broiler chickens. Two hundred and twenty five (225), one day old chicks were purchased from local commercial hatchery and were randomly divided into 5 groups and each group had 3 replicates of 17 chicks in a completely randomized design. Five iso-caloric and iso-nitrogenous (ME 2998kcal/ kg and CP 23.21%) broiler starter and finisher (ME 2990 kcal/ kg and CP 20.33%) experimental diets containing 0, 150, 200 and 250g Lacto acidophilus® for T1-T4 respectively and T5 containing Oxytetracycline were formulated. Broiler starter and finisher diets were fed from 0-3 and 4-7 weeks, respectively. Data obtained were subjected to analysis of variance using Statistical Analysis System and significant differences between treatments means were separated using Duncan Multiple Range Test. There were significant (P<0.05) difference in final weight, weight gain, average daily weight gain (ADWG), total feed intake (TFI), average daily feed intake (ADFI), feed conversion ratio (FCR) and feed cost/kg gain across the treatment groups. It was observed that chickens fed dietary Oxytet (oxytetracycline) had the best results in terms of the final body weight, weight gain and ADWG but similar to those fed 150 and 200g Lacto acidophilus® addition levels. The percentage dry matter (DM), crude protein (CP), crude fibre (CF), ether extracts (EE) and ash retention increased with increase in Lacto acidophilus® inclusion with exception for 250gLacto acidophilus® inclusion (CP, CF, EE). However, it was observed that chickens fed dietary levels of Lacto acidophilus® had the best live weight, dressed weight and dressing percentage compared to the control group. It was concluded that chickens fe Lacto acidophilus® inclusion may as well compete favorably with antibiotics growth promoter fed chickens.     Une expérience a été menée pour évaluer l'efficacité de Lacto acidophilus sur la performance de croissance, les caractéristiques de la carcasse et la digestibilité nutritive des poulets de gril. Deux cent vingt-cinq (225), poussins d'un jour ont été achetés à l'écloserie commerciale locale et ont été répartis au hasard en 5 groupes et chaque groupe avait 3 répliques de 17 poussins dans une conception complètement randomisée. Cinq iso- caloriques et iso-azotés (le 'ME' 2998kcal/kg et le 'CP' 23.21%) démarreur et finisseur de poulet de gril (le 'ME' 2990 kcal/kg et le 'CP' 20.33%) des régimes expérimentaux contenant respectivement 0, 150, 200 et 250 g d'acidophilus lacto® pour le T1-T4 et le T5 contenant de l'Oxytetracycline ont été formulés. Les régimes d'entrée et de finisseur de poulet de gril ont été alimentés de 0-3 et 4-7 semaines, respectivement. Les données obtenues ont fait l'objet d'une analyse de la variance à l'aide du système d'analyse statistique et des différences significatives entre les moyens de traitement et ils ont été séparées à l'aide du test à distance multiple Duncan. Il y avait une différence significative (P<0,05) dans le poids final, le gain de poids, le gain de poids quotidien moyen (le 'ADWG'), la consommation totale d'aliments pour animaux (le 'TFI'), l'apport quotidien moyen en aliments pour animaux (ADFI), le ratio de conversion des aliments pour animaux (FCR) et le gain coût/kg des aliments pour animaux dans les groupes de traitement. On a observé que les poulets nourris oxytet alimentaire (oxytetracycline) ont eu les meilleurs résultats en termes de poids corporel final, gain de poids et de 'ADWG', mais similaire à ceux nourris 150 et 200g Lacto acidophilus® niveaux d'addition. Le pourcentage de matière sèche (le 'DM'), de protéines brutes (le 'CP'), de fibres brutes (le 'CF'), d'extraits d'éther (le 'EE') et de rétention de cendres a augmenté avec l'augmentation de lacto acidophilus® l'inclusion à l'exception de 250 glacto acidophilus® inclusion (CP, CF, EE). Cependant, il a été observé que les poulets nourris à des niveaux alimentaires de Lacto acidophilus® avaient le meilleur poids réel, le poids habillé et le pourcentage de vinaigrette par rapport au groupe témoin. Il a été conclu que les poulets feLacto acidophilus® inclusion peut aussi bien rivaliser favorablement avec les antibiotiques promoteur de croissance nourris poulets.

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.

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.
