This study was carried out to determine the effect of dietary supplementation of Cymbopogon citratus oil (LGO) on the performance and carcass characteristics of broiler chicks. A total of 250 one-day-old chicks of Ross 308 strain were divided into 5 treatments with 5 replicate per treatment of 10 birds in a completely randomized design. The dietary treatments include a control diet (T1) with no Cymbopogon citratus oil (LGO). LGO was supplemented at 0.1%, 0.2 %, 0.3 % and 0.4 % in diets 2, 3, 4 and 5 respectively. The experiment lasted for 56 days; feed and water were administered ad libitum. Results obtained revealed that average daily weight gain (ADWG), average daily feed intake (ADFI), average daily water consumption (ADWC) and feed:gain were significantly influenced by LGO (P˂0.05). Highest mortality was recorded in T1 (4.15 %) followed by T2 (1.71 %), T3 (0.50 %), none was recorded in T4 and T5 (P˂0.05). dressing percentage, carcass and relative organ weight were significantly different among the treatments (P˂0.05).There was no noticeable inflammation was observed on the liver, kidney spleen and other internal organs. It was concluded that LGO is rich in phytochemical constituents and can be safely included in the diets of broiler chicks up to 0.4 % level without causing any detrimental effect on the growth performance and carcass of birds.

Randomized Design

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.

Sweet Potato Vine

The study was carried out to determine the feed value of replacing maize with graded levels of sweet potato vine – cassava composite meal (SPV-CCM) to rabbits. Five treatment diets were formulated to contain SPV-CCM inclusion levels of 0% (control), 25%, 50%, 75% and 100%. Thirty weaned rabbits of mixed breeds and sexes were used for the experiment. They were randomly allocated to five dietary treatments with one rabbit as a replicate in a completely randomized design. Feed and water were provided ad libitum. Parameters measured were that of growth, digestibility, carcass and economics of production. The result showed that there was no significant (P>0.05) difference effect on final weight, total weight gain, daily weight gain and feed conversion ratio across the dietary treatments. There was no significant (P>0.05) difference on crude protein digestibility, crude fibre and ether extract which were within the required values for rabbit. There was no significant (P>0.05) difference on live weight at slaughter, dressing percentage, heart, liver, kidney, lungs/trachea, esophagus, stomach, small intestine, caecum, large intestine and visceral fat, there was however, a significant (P<0.05) difference in dressed weight, pancreases, spleen and kidney fat. A high cost of feeding, cost per kilogram diet and production was recorded in T and low cost of feeding, cost per kilogram diet and production in T . The result showed that 1 5 maize could be replaced by SPV-CCM up to 100% without any adverse effect on their performance, nutrient digestibility and carcass characteristics. However, the optimum performance was observed when 75% SPV-CCM replaced maize in the diet. Replacement of maize with SPV-CCM has relative cost advantage over the control diet and so should be incorporated in the diet of rabbit up to the level considered in this study.

The effect of fermentation of cassava tuber followed by its gelatinization was evaluated as a method of processing cassava for use as source of energy in broiler diets. Peeled and unpeeled cassava tubers were separately fermented in water for 4 days, dried in the sun and then milled to produce fermented peeled and unpeeled cassava tuber meals, respectively. The dusty meals were then gelatinized by mixing with water in pots seated over fire at the rate of 1kg of cassava tuber meal to one litre of water and stirred until they gelatinized into fufu. The gelatinized pastes were then taken bit by bit and flattened on polythene sheets and dried in the sun. The resultant fermented and gelatinized peeled and unpeeled cassava tuber cakes were then milled to produce fermented and gelatinized unpeeled cassava tuber meal (UFGC), a brownish-looking non-dusty product and fermented and gelatinized peeled cassava tuber meal (PFGC), an ash-looking non-dusty product. Three broiler diets were made such that diet 1 (control) contained maize as source of energy, while in diets 2 and 3, the maize in the control diet was completed replaced with UFGC and PFGC, respectively, both in the starter and finisher diets. One hundred and twenty (120) broiler chicks were divided into 3 groups of 40 birds each and each group assigned to one of the diets, using completely randomized design, and fed for 4 weeks with the starter diets and finisher diets for another 4 weeks. At the starter phase, the UFGC diets gained significantly (P < 0.05) less weight and consequently had poorer feed conversion ratio. There were no significant differences in feed intake (P < 0.05). At the finisher phase, the group on UFGC gained significantly (P < 0.05) more body weight. The groups on cassava diet tended to consume less feed and so had better feed conversion ratio. There were no differences (P > 0.05) in dressed weights and weights of internal organs but the group on PFGC diet accumulated significantly (P < 0.05) more abdominal fat.

The present study was carried out for six weeks to investigate the effects of adding graded levels (0, 0.1 and 0.5%) of garlic (Allium sativum) powder to the basal experimental diet on the growth performance and carcass characteristics of broiler chicks. One hundred and eighty (n = 180) day old unsexed white commercial broiler chicks (Cobb-400) were randomly distributed into three dietary treatments of 60 birds/treatment and each treatment contained 4 replicates (15 birds/replicate). The dietary treatments were controlled basal diet (T1), and a diet supplemented with garlic powder at 0.1% (T2) and 0.5% (T3). Daily feed intake, weekly body weight, and residue leftover were recorded to calculate the feed conversion ratio (FCR). At the end of the experiment, six birds from each group were sacrificed to determine the carcass characteristics. Results revealed that dietary supplementation of 0.1% garlic powder (T2) significantly (p less than 0.01) improved body weight, body weight gain, feed intake and FCR as compared to birds supplemented with 0.5% garlic powder (T3) and control diet (T1). Dietary supplementation of 0.1% garlic (T2) resulted in significant (p less than 0.05) improvement in dressed yield as comparedto T3 and T1. On the other hand, comparable (p greator than 0.05) effect was observed on shrinkage loss, blood loss, feather loss, eviscerated yieldand relative weight of giblet. Thus, dietary supplementation of 0.1% garlic powder had beneficial effects on growth performance and dressed yield of broiler chicks.

This study was conducted to investigate the effects of dietary supplementation of Endoglucanase producing Bacillus subtilis sp. fermented product (EBFP) on growth performance and meat characteristics in broilers. A total of 480, 1 day old ROSS male broiler chicks were obtained from a local hatchery and randomly allotted to 1 of 4 dietary treatments with 6 replicate pens consisting of 20 chicks. Three additional diets were prepared by mixing 0.1% of commercial cellulase, 0.1%, and 0.2% of EBFP with the control diet and all chicks were fed experimental diets and water ad libitum. Feed intake and body weight (BW) were recorded at 0, 3, and 5 week of the experiment. At the end of the experiment, birds fed a diet containing 0.1% of EBFP had the highest BW compared to birds in other groups (P > 0.01). During 0 to 5 week the experimental period, the dietary addition of 0.1% EBFP significantly increased (P > 0.01) BW gain that was higher than that of birds fed the diet in which only a commercial cellulase was added. No significant difference among treatments was observed in carcass weight, carcass yield, left breast, and thigh meat. These results suggest that dietary addition of cellulolytic probiotics may enhance growth performance compared with the single use of probiotics or enzymes.

The objective of the study was to evaluate the effect of two methods of processing Bambara Groundnut Offal (BGO), toasted and enzyme supplemented in broiler chicken diets on haematology and carcass characteristics of broiler finisher chicken. One hundred and eight (108) four- weeks- old unsexed commercial broiler chicks were divided into three groups (T10% T220% T320%) of 36 birds, each replicated three times with 12 birds per replicate in a completely randomized design and fed for 28 days. Haematological parameters were not significantly (p>0.05) affected. Result of carcass characteristics showed that live weight, eviscerated weight, dressed weight, back weight, drumstick weight, breast weight, thigh weight and caecum weight were significantly (p<0.05) affected. Birds fed enzyme supplemented BGO diets recorded higher weights compared with birds fed toasted BGO and the control diets. Other carcass  characteristics such as wing weight, neck weight, head weight,  shank weight and other internal organ characteristics were not significantly (p>0.05) affected. From the result, significant parameters have shown that birds fed bioenzyme supplemented BGO diets were superior to birds fed toasted BGO and the control diet. It is therefore recommended that 2g/kg bioenzyme supplemented BGO diet should be used at 20% BGO inclusion rate for finishing broiler chicken without adverse effect on the haematology and for increased carcass weight.

An experiment was conducted with one hundred and eighty (180) unsexed day old broiler chicks of Arbor acre strain to investigate the effect of feeding diets supplemented with water soaked sweet orange peel meal (SOP) on the performance and carcass characteristics of broiler chicken. The broiler chickens were randomly distributed into six (6) dietary treatments of 30 birds per treatment which were further distributed into three (3) replicates of 10 birds per replicate from day old, in a completely randomized design. Six dietary treatments were formulated such that, T1 which is control was maize based. In diets 2, 3, 4, 5 and 6, sweet orange peels replaced maize at various duration of water soaked, 0, 24, 48, 72 and 96 hours respectively and incorporated at 30% inclusion. Data were collected on feed intake and weekly weight gain. Six (6) birds were randomly selected per treatment starved over night, weighed and sacrificed by cervical dislocation for carcass analysis. Result reveals significant (p<0.05) difference in daily feed intake, there was no significant (p>0.05) difference on final weight and daily weight gain. The result of carcass characteristics showed no significant (p>0.05) difference in carcass cut and internal organs. It can be concluded that supplementing broiler diets with water soaked sweet orange peels had no detrimental effects on the performance and carcass characteristics.

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.

Phytase is essential for enhancing nutritional value of feed and improving animal growthperformance and health. A study was conducted to evaluate the influence of Smartchoicephytase enzyme supplementation in the diet of starter broiler chickens. A total of 150 Rossstrain broiler chicks were used for the study and allotted to five treatment groups of 30 birdseach. Each group was further divided into three replicates of 10 birds per replicate. Five isonitrogenous(21.40% CP) and iso-caloric (2975.40 kcal/kg ME) dietary treatments werecompounded to contain 0g/100kg (T ), 10g/100kg (T ), 15g/100kg (T ), 20g/100kg (T ) and 1 2 3 425g/100kg (T ) of a commercial Smartchoice phytase enzyme preparation for 28 days in a 5Completely Randomized Design (CRD). Feed and water were provided to the chicks adlibitum.Daily feed intake and weekly body weight were measured. The result showed that thedaily feed intake and daily protein intake were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation. Final live weight, daily weight gain and total weight gain weresignificantly different among treatments. Protein efficiency ratio were significantly (P<0.05)higher in T (2.10) than T (1.80) but similar to T (2.05), T (2.05) and T (1.96). Feed 1 5 2 3 4conversion ratio was significantly (P<0.05) different in T5 (2.58) and T (2.02) but similar 1(P>0.05) in T (2.02), T (2.28), T (2.31) and T (2.38). Mortality was lowest in T5. Total feed 1 2 3 4cost per bird and daily feed cost per bird were not affected (P>0.05) by Smartchoice phytaseenzyme supplementation while cost per kg of feed and daily feed cost per bird were notsignificantly (P>0.05) affected. The findings from this study showed that Smartchoicephytase enzyme could be supplemented up to 20g per 100kg in the diet of starter broilerchickens.
