SummaryThe influence of different inclusion levels of a biologically active peptide derived from soybeans by enzymatic hydrolysis, on growth performance, foot pad lesions and carcass characteristics in broilers were examined in this study. Starter (1 to 21 d) and finisher (22 to 42 d) diets, based on maize and soybean meal, were subjected to seven inclusion levels of a commercial soybean bioactive peptide (SBP) product (Fortide, Chengdu Mytech Biotech Co. Ltd., Chengdu, Sichuan, China) at 0.0, 1.0, 2.0, 3.0, 4.0, 5.0 and 6.0 g/kg of diet. All diets were equivalent in respect of energy density, digestible amino acids and other nutrients. A total of 840, one-day-old male broilers (Ross 308) were allocated to 42 pens (20 birds/pen), which were randomly assigned to seven dietary treatments. During the starter period, there was no significant effect of SBP on weight gain and feed intake of the birds. However, a significant (P < 0.05) effect of SBP was observed for the feed conversion ratio (FCR), with SBP inclusion at 3.0 g/kg and above showing lower (P < 0.05) FCR values compared to the diet with no SBP. No effect of SBP was observed for weight gain and feed intake over the whole trial period. However, SBP inclusion tended (P = 0.06) to influence the FCR of birds. Increasing SBP inclusion level resulted in gradual decrease in FCR values, with SBP inclusion at 5.0 and 6.0 g/kg showing lower FCR values compared to the diet with no SBP. Overall, the present study suggests that dietary supplementation of SBP in broiler diets has the potential to improve FCR and to be used as a novel functional protein in poultry diets.

The present study proposes to examine the effect of dietary levels of metabolizable energy, under a fixed nutrient:calorie ratio, on the production performance; body fat and protein deposition; and carcass characteristics of free-range broilers from 1 to 84 days of age. Nine hundred unsexed chicks were allocated to six treatments in a completely randomized design with six replicates of 25 birds each. Treatments consisted of diets with varying levels of metabolizable energy (2700, 2800, 2900, 3000, 3100 and 3200 Kcal ME/kg of diet) and a fixed proportion of nutrients relative to the energy level according to the nutritional requirements for each rearing phase. Body weight, weight gain, feed intake, feed conversion, production viability, metabolizable energy intake, protein intake, lysine intake, body fat deposition, body protein deposition and carcass characteristics were evaluated. Data were subjected to analysis of variance and, later, to regression analysis. Increasing levels of metabolizable energy, coupled with a fixed nutrient:calorie ratio, reduced feed intake, increased body weight and weight gain, improved feed conversion and did not affect carcass characteristics. In conclusion, adjusting the nutrient supply according to the dietary energy level improves production performance by improving feed conversion, ensuring adequate nutrient intake and preserving fat and protein deposition in the carcass when the metabolizable energy level is raised up to 3200 Kcal/kg in all rearing stages.

The progressive increase in the cost and scarcity of conventional feedstuffs, especially energy and protein sources has resulted into a continuous effort in researching into the possible utilization of the under - exploited wild legumes in poultry feed formulation. Several Researchers had reported on the utilization of Moringa oleifera leaf meal in poultry diets whereas; few reports exist on the utilization of Moringa seed. Therefore, this study wasconducted to evaluate the effect of graded dietary levels of moringa seed cake (MSC) on the performance of broiler chickens. A total of 195, one day old Arbor Acre broiler chicks were randomly assigned into five dietary treatments of moringa seed cake, each treatment having three replicates in a completely randomized design. MSC was included at levels of 0, 5,10, 15 and 20% respectively. Feed and water were given ad- libitum. Proximate composition ofMSC showed that it is high in energy, crude protein and ether extract with3304. 39 ME kcals/ kg, 32.49 % and 17.70%, respectively. Birds fed 5% MSC diet were better than the birds on the other levels of MSC diets in terms of growth and carcass characteristics. The results obtained from growth study revealed a significant declined in, final weight, weight gain, feed intake, and feed conversion ratio as the inclusion levels of MSC increased beyond 5% in thediets. The birds on control diet had the best result in terms of final weight , daily weight gain and daily feed intake of 2974g/bird, 52.4g/bird / day and 107.51g/bird/ day respectively followed by those fed diet containing 5% MSC with 2183.4g/bird, 38.24/bird /day and 95.66g/bird /day respectively. whereas, the birds fed 20% MSC had the least (P>0.05) final weight, daily weight gain and daily feed intake of 560 g/bird, 9.26g/bird /day and 33.51g/bird/day respectively. Carcass characteristics followed similar trend as the growth parameters. Hematological indices showed significant differences across the dietary treatments, however, the results were within the normal range except for the white blood cell. It can therefore be, concluded that the inclusion of MSC in broiler chicken diet should not exceed 5% for optimum growth and general performance.

The disposal of red grape pomace (GP) in landfills and by incineration has negative impacts on the environment. It is, therefore, imperative that alternative and sustainable ways of managing this waste product are identified. Using GP as a source of nutrients and beneficial bioactive compounds in avian diets is a potential waste-reduction and valorization strategy that promotes sustainable agriculture. However, there is limited information on the valorization of GP for this purpose. This study, therefore, investigated the effect of dietary inclusion of GP on growth performance, blood parameters, carcass characteristics, and breast meat quality traits of broilers. Four hundred, two-week old Cobb 500 broilers (279.2 ± 18.87 g) were allocated to 40 pens. Five isonitrogenous and isoenergetic diets were formulated by including GP in commercial broiler diets at 0 (GP0), 2.5 (GP25), 4.5 (GP45); 5.5% (GP55); and 7.5% (GP75). Feed intake, weight gain, feed utilization efficiency, hematology, serum biochemistry, carcass characteristics, and breast meat quality traits were measured. Chickens on GP75 had the least feed intake (p < 0.05) but there were no dietary effects on weight gain. Birds on GP0 had the highest (p < 0.05) feed conversion ratio (1.79) while those fed GP75 had the lowest (p < 0.05) ratio (1.45). Breast meat from broilers offered GP75 had the highest (p < 0.05) redness value (0.75) while the GP0 diet promoted the least (p < 0.05) redness value (0.49). Broilers fed GP55 and GP75 diets had higher (p < 0.05) feed conversion efficiency compared to GP0 birds. Inclusion of GP in broiler diets has the potential to reduce feed costs, thus making this valorization strategy a sustainable alternative to current pomace disposal methods. Adoption of this waste-reduction and valorization strategy promotes sustainable agriculture by contributing to food security and environmental stewardship.

The effect of replacing an antibiotic growth promoter in the diet with a probiotic on growth performance, carcass characteristics and nutrient retention was studied in broilers (Vencobb 430) fed with and without meat cum bone meal (MBM). This experiment which lasted for 42 days consisted of six dietary treatments viz., basal diet (BD), basal diet with MBM (MBM), basal diet with antibiotic (AB), basal diet with probiotic (PB), basal diet with MBM and antibiotic (MBM+AB) and basal diet with MBM and probiotic (MBM+PB). Three-hundred, day-old chicks were randomly allotted in the beginning to these six groups. Body weight gain, feed intake and feed conversion ratio were significantly (P less than 0.05) affected at 4th week of age. Overall, highest body weight gain was recorded in birds fed with AB and PB. Inclusion of probiotic in MBM also showed improved body weight gain when compared to MBM group. Highest feed intake and feed conversion ratio was recorded with AB and PB groups. Birds supplemented with MBM+PB showed improved feed intake and feed efficiency when compared to MBM+AB and MBM diet supplemented groups. Higher dry matter, crude protein, calcium and phosphorus retention (P less than 0.05) was observed in birds supplemented with PB or AB in diet without MBM when compared to their control. In MBM supplemented groups addition of PB or AB improved crude protein retention. Birds supplemented with PB or AB with or without MBM showed a significant (P less than 0.05) increase in thigh yield and a non significant reduction in fat yield when compared to their control groups.

Means of cutting down cost of feed resources in order to bridge the wide gap between demand and supply of animal protein in livestock production is a great concern in the poultry industry. This study was conducted to investigate the effect of feeding diets containing soaked and fermented Baobab seed meal (BSM) on the growth performance of broiler starter chicks. A total of 150, one-day old chicks were randomly distributed into five treatment groups. Treatments were replicated three times with 10 chicks per replicate in a completely randomized design (CRD). The dietary groups were designated as T1 for control (0 % BSM), T2 (7.5 % SBSM), T3 (15.0% SBSM), T4 (22.5% FBSM) and T5 (30 % FBSM). Parameters monitored include final weight, weight gain, feed intake, feed conversion ratio, feed cost per kg gain (N) and mortality (%) The experiment lasted for 4 weeks. The results showed that the dietary treatments had significant (P<0.05) effect on all the parameters measured. Final weight and total weight gain were similar and significantly (P<0.05) higher in birds fed diets T2 and T4 when compared to other dietary treatments. However, birds in T5 group had the least significant (P<0.05) values 366.67 and 217.34 g/bird respectively. Daily weight gain (7.76 g/bird/day), total and daily feed intake (873.33 g and 31.19 g/bird/day) of birds followed similar trend and were significantly (P<0.05) lower in T5 group compared to other treatments. Feed conversion ratio of birds fed diet T5 had significantly (P<0.05) higher value (4.29) when compared to those in other treatment groups. Feed cost per kg gain (N) was significantly (P<0.05) lower and similar in birds fed T2, T3 and T4 when compared to values obtained in the control group (N253.27) and T5 (N 327.52). Mortality (%) only occurred in birds fed T5. It was therefore concluded that inclusion of 22.5% fermented baobab seed meal in broiler diets improved performance and had no negative effect on the health status of birds.     Des moyens de réduire le coût des ressources alimentaires afin de combler le defi posé à cause de la demande et l'approvisionnement en protéines animales dans la production animale est une grande préoccupation dans l'industrie avicole. Cette étude a été menée pour étudier l'effet des regimes alimentaires contenant de la farine de graines de baobab trempée et fermentée (le 'BSM') sur les performances de croissance des poussins de départ. Un total de 150 poussins âgés d'un jour ont été répartis au hasard en cinq groupes de traitement. Les traitements ont été répliqués trois fois avec 10 poussins par réplique dans une conception complètement randomisée (le 'CRD'). Les groupes diététiques ont été désignés comme T1 pour le contrôle (0% BSM), T2 (7,5% SBSM), T3 (15,0% SBSM), T4 (22,5% FBSM) et T5 (30% FBSM). Les paramètres surveillés comprennent le poids final, le gain de poids, la prise alimentaire, le taux de conversion alimentaire, le coût de l'alimentation par kg de gain (N) et la mortalité (%). L'expérience a duré 4 semaines. Les résultats ont montré que les traitements diététiques avaient un effet significatif (P <0,05) sur tous les paramètres mesurés. Le poids final et le gain de poids total étaient similaires et significativement (P<0,05) plus élevés chez les oiseaux nourris avec les régimes T2 et T4 par rapport aux autres traitements diététiques. Cependant, les oiseaux du groupe T5 avaient les valeurs les moins significatives (P <0,05) 366,67 et 217,34 g / oiseau respectivement. Le gain de poids quotidien (7,76 g / oiseau / jour), l'apport alimentaire total et quotidien (873,33 g et 31,19 g / oiseau / jour) des oiseaux ont suivi une tendance similaire et étaient significativement (P<0,05) inférieurs dans le groupe T5 par rapport aux autres traitements. Le rapport de conversion alimentaire des oiseaux nourris au régime alimentaire T5 avait une valeur significativement plus élevée (P <0,05) (4,29) par rapport à ceux des autres groupes de traitement. Le coût de l'alimentation par kg de gain (N) était significativement (P <0,05) plus faible et similaire chez les oiseaux nourris T2, T3 et T4 par rapport aux valeurs obtenues dans le groupe témoin (N253,27) et T5 (N 327,52). La mortalité (%) n'est survenue que chez les oiseaux nourris au T5. Il a donc été conclu que l'inclusion de farine de graines de baobab fermentée à 22,5% dans les régimes alimentaires des poulets de chair améliorait les performances et n'avait aucun effet négatif sur l'état de santé des oiseaux.

This study was carried out to evaluate the growth performance and carcass characteristics of finisher broiler chickens fed diet containing cooked cocoyam tubermeal as energy source in place of maize. The proximate composition of cooked cocoyam tubermeal showed that it contained 13.11% moisture, 2.60% ash, 3.90% crude protein, 9.45% crude fiber, 1.85% ether extract and 70.13% NFE. In the finisher feeding trial, the cooked cocoyam tubermeal was used to replace maize at levels of 25%, 50%, 75% and 100% respectively in the control diet. Each finisher diet was fed to a group of 30 finisher broiler chicken for 4 weeks using completely randomized design. Each treatment was divided into 3 replicates of 10 broiler chicks each. The birds were kept on deep litter and were given feed and water ad-libitum. Parameters measured include ifinal body weight, body weight gain feed intake, feed conversion ratio, carcass characteristics and economics of production. In the finisher feeding trial, the feed intake of the finisher broilers on diets 2, 3 and 4 were similar and compared favourably with those on the control diet. The finisher group on 100% CCYM (diet 5) recorded the lowest feed intake possibly because of the dustiness of the feed. The body weight gain of the finisher broilers on diet 2 (25%) cooked cocoyam tubermeal compared favourably with the control group and was significantly (P<0.05) higher than those on other diets. It appeared that the finisher broilers could not tolerate high levels of cooked cocoyam meal due to dustiness of the feed and its anti-nutritional factors. The cost of production per kg finisher broilers was cheapest for diet 5(100% CCYM) (N356.72) and the costliest was for diet 3(50% CCYM) (N588.28). The internal organs expressed as percent of the live weight were not affected by the treatments. In terms of carcass characteristics, the finisher broilers on diet 2(25% CCYM) recorded the highest breast muscle which was significantly different (P<0.05) from other groups. There were no significant different (P>0.05) on percent back cut, drumstick, head, shank, thigh, neck and wings of the finisher broilers on all the treatments. There were no significant differences (P > 0.05) in percent dressed weight of the finisher broilers on cooked cocoyam based diets. The results of the trial have shown that cooking cocoyam corms (Xanthosoma sagittifolium) for 30 minutes was effective for reducing the cyanide oxalate, tannin, phytic acid and saponin content and that cooking did not affect the proximate composition of tannia. Cooked cocoyam tubermeal could be used to replace maize up to 25% in the diet of finisher broiler chicken without affecting body weight gain, feed intake and feed conversion ratio as indicated in this study.

An experiment was conducted with commercial broilers to investigate the effects of feeding citric acid, acetic acid and their combination on their performance and to determine the economic competence of using citric acid and acetic acid in broiler rations. A total number of 108 one day old straight run broiler chicks were distributed to four dietary treatments i.e. 0 % citric or acetic acid (A), 0.5% citric acid (B), 0.5% acetic acid (C) and their combinations 0.5% citric acid and 0.5% acetic acid (D). The birds were reared in cages. Body weight gains, feed conversion ratio (FCR), mortality, dressing yield and carcass characteristics were recorded. The performance showed significant increase in body weight gain (P<0.05) when compared with the control during 0-5 weeks of age on 0.5% citric acid (B). Feed consumption increased (P<0.05) at 2nd and 3rd weeks of age on 0.5% citric acid (B). Feed conversion was found higher (P<0.05) during 0-5 weeks of age in treatment B when compared to those of the other treatments. Carcass characteristics were not affected by dietary treatments. The highest mortality was found in treatment A and treatment C due to excessive hot. It may be concluded that use of 0.5% citric acid in the diet of broilers may have better performance in respect of live weight gain and feed conversion.

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 objectives of the study were to determine if feed conversion ratio (FCR) in broilers fed wet Hard Red Spring (HRS) as compared to Durum-based wheat diets could be reduced by: (a) diluting HRS with Durum wheat, (b) pelleting of the wheat, (c) adding different levels of water to the diet, or (d) restricting intake of diets to which water was added. Three wheat types [Durum, HRS and a Composite (50:50) sample] were ground, with one portion of the ground grain being pelleted and reground before both forms of each wheat type were included at 80% of a basal broiler diet. All diets were supplemented with a commercial wheat enzyme and fed as a mash. Each of the six diets was fed in one of four feed regimens: DRY (as is); WET1.2 (DRY with 1.2 g water g-1 feed); WET0.6 (DRY with 0.6 g water g-1 feed); and RWET1.2 [WET1.2 diet treatment restricted-fed to 120% of the previous day’s DRY feed intake (on an air-dried basis) for each diet type]. This provided 24 dietary treatments each fed to six cages of five male broilers from 1 to 21 d of age. The wet diets were prepared daily. Among the feed regimens WET1.2 resulted in the significantly highest 21-d body weight. The significant increase in feed intake and FCR of HRS-based diets with added water was reduced significantly by diluting this wheat with Durum wheat. Feeding the unpelleted Composite wheat sample significantly improved growth rate over either wheat alone, presumably due to an improved balance of nutrients. Pelleting significantly reduced intake of wet HRS-based diets and increased apparent metabolisable energy (AME), resulting in a marked reduction in FCR compared to unpelleted diets. There was some value in using less water in HRS-based, but not in Durum-based diets, with respect to FCR and metabolisable energy retention. Physical restrictions of feed intake reduced FCR of wet (WET1.2) unpelleted HRS diets, but did not affect the same diet when wheat was pelleted. Further work is required to establish the optimum consistency of feed in a wet form to maximize feed intake and growth while minimizing FCR. Key words: Wheat, wet feeding, enzymes, feed intake, broilers

A feeding trial was conducted using broilers to determine the optimum inclusion levels of locally produced natural vitamin premix (LPNVP) and compare the performance to a commercial vitamin mineral premix(CVMP) commonly sold within Nigeria. Feed intake, weight gain and feed utilization efficiency varied (P<0.05) among the various dietary treatments considered. Feed utilization efficiency and weight gain were inversely related to feed intake for birds fed LPNVP-based diets and these measurements were lower (P<0.05) than values observed for birds fed CVMP based diets. Nutrient retentions were also not influenced (P>0.05) by the various inclusion levels of LPNVP studied, although these criteria were also significantly lower for birds fed LPNVP-based diets compared with birds fed CWMP-based diets. Although, dressing percentage was not affected (P>0.05) by the dietary levels, relative fresh organs and primal cut weights were different (P<0.05) for birds fed the various levels of LPNVP and the control birds fed CVMP-based diets. It was however cheaper (P<0.05) to use LPNVP than CVMP as a source of vitamin for broilers.
