The stress of high environmental temperature may have a deleterious influence on the performance of broiler chickens by reducing feed intake, live weight gain and feed efficiency. Exposing chicks to 36-38°C for 24h at 5d of age reinforces the resistance of older (6 to 7 wk-old) broilers to heat stress (De Basillo et al., 2003). Several studies have revealed that antioxidant nutrient supplementation especially vitamin C and E can be used to alter the negative effect of environmental stress (NRC, 1984). Combination of antioxidant vitamins generally shows greater antioxidant activity than that of each component alone. The objective of this study was to investigate the effects of early age thermal conditioning and vitamin C, E supplementation on performance, carcass characteristic in broiler chickens reared under heat stress.

Objective: This study aimed to determine the effect of intermittent feeding and cold water on performance and carcass traits in broiler chickens between 4 to 6 wk of age exposed to daily high temperature.Methods: Broilers were assigned to four treatment groups according to a 2×2 factorial design between 22 to 42 d of age (80 broilers per treatment, 4 replications). Broilers were divided into two main groups as feeding type (ad-libitum [AL] and intermittent [IF] for 6 h daily) and sub-groups as water temperature (normal [NW], 24.9°C and cold [CW], 16.4°C). Heat treatment was applied between 11.00 to 17.00 h daily between 22 to 42 d of age.Results: Live weight at 6th wk was not affected by feeding type and water temperature, but the live weight was significantly higher in IF chickens at the 5th wk (p<0.05). Average weekly gain of IF broiler chickens were higher compared to AL group at 4, 5, and 6 wk of age (p<0.05). Although feeding type did not affect feed intake in 4 and 5th wk, feed intake was higher in IF chickens at 6th wk (p<0.01). In addition, feeding type and water temperature did not affect feed conversion ratio and interactions were not significant (p>0.05). Water temperature had no significant effect on heart, liver, gizzard, and abdominal fat percentages (p>0.05).Conclusion: It is concluded that IF increased the average weekly gain in chickens reared under daily heat stress for 6 h between 22 to 42 d of age. IF in hot environmental conditions slightly increased performance without adversely affecting health, welfare, and physiological traits, whereas CW implementation had no significant effect on performance. It can also be said that IF suppresses a sudden increase in body temperature depending on age and live weight.

In this experiment, the effect of hydroalcoholic grape seed extract (GSE) and vitamin C feed supplementation on some blood parameters and heat shock protein 70 (<em>HSP70</em> gene) expression of broiler chickens suffering from chronic heat stress was investigated. Experimental diets included control diet (with no additive), 3 levels of GSE (150, 300, 450 mg/kg), and one level of vitamin C (300 mg/kg). Each diet was fed to 5 replicates of 12 male chicks each, from d 1 to 42. The birds suffered from chronic daily heat stress under 34±1°C temperature with 65 to 70% relative humidity for 5 h from 29 to 42 d of age. Results showed that 300 mg/kg GSE supplementation increased body weight of broilers both before and after heat stress condition (at 28 and 42 d, respectively). Also, birds fed 300 mg GSE/kg diet had higher European production efficiency factor during the whole period of the experiment. Supplementation of GSE decreased the concentration of serum glucose at 28 and 42 d; at 42 d (during heat stress condition) and at 450 mg/kg diet it decreased cholesterol, triglyceride, lowand very low density lipoprotein concentration of serum blood. Vitamin C supplementation decreased serum cholesterol concentration of broilers suffering from heat stress. <em>HSP70</em> gene expression in heart and liver of broilers reduced by GSE and vitamin C supplementation pre- and during chronic heat stress condition.

The stiff competition between man and livestock for maize as energy feedstuff has resulted in the high cost of poultry products. Therefore, a study was conducted to evaluate the effect of feeding acha-based diet varying dietary plant protein to broiler chickens on carcass characteristic and organ proportions. A total of 120, one day-old Abor acre broiler chicks were used for the study in a Complete Randomized Design. Four dietary plant proteins were included in the broiler chicken diet at 28% level with an acha grain as the main energy source. Diet 1 contains 28% groundnut cake, while diets 2, 3 and 4 contain 28% of full fat soyabean, soyabean cake and cashew nut meal, respectively. The birds were randomly allotted to the 4 treatment groups, with each group having 30 birds which was further subdivided into 3 replicates of 10 birds each. This study lasted for 56 days. At the end of the feeding trial, carcass evaluation was carried out. One bird per replicate was randomly selected, starved overnight and slaughtered by severing the jugular vein. The visceral were removed and weighed. The results showed that birds fed dietary soyabean cake (Diet 3) had the highest live weight gain (2155.00g), slaughtered weight (1855.00g), defeathered weight (1838.33g), dressed weight (1455.00g) and shank (112.00g). The organ proportions showed significant differences (p<0.05), though followed no definite trend. In conclusion, birds fed diet 3 gave the best carcass weight, and the organ proportions showed no negative effect as par the diets offered the birds. Thus, inclusion of 28%, soyabean meal in an acha-grain based diets proved to be superior over groundnut cake and cashew nut and it is therefore recommended.   La vive concurrence entre l'homme et le bétail pour le maïs comme aliment énergétique a entraîné le coût élevé des produits de volaille. Par conséquent, une étude a été menée pour évaluer l'effet de l'alimentation à base d'acha avec des protéines végétales alimentaires variées sur les poulets de chair ainsi que les caractéristiques de la carcasse et les proportions des organes. Un total de 120 poussins de chair de 'Abor acre' âgés d'un jour a été utilisés pour l'étude dans un plan randomisé complet. Quatre protéines végétales diététiques ont été incluses dans le régime des poulets de chair à un taux de 28%, le grain d'acha étant la principale source d'énergie. Le régime 1 contient 28% de farine d'arachide, tandis que les régimes 2, 3 et 4 contiennent 28% de farine de soja, de gâteau de soja et de noix de cajou, respectivement. Les oiseaux ont été répartis au hasard dans les 4 groupes de traitement, chaque groupe comptant 30 oiseaux qui ont ensuite été subdivisés en 3 répétitions de 10 oiseaux chacun. Cette étude a duré 56 jours. À la fin de test d'alimentation, une évaluation de la carcasse a été effectuée. Un oiseau par réplique a été sélectionné au hasard, affamé pendant la nuit et abattu en sectionnant la veine jugulaire. Les viscéraux ont été prélevés et pesés. Les résultats ont montré que les oiseaux nourris avec du gâteau de soja diététique (régime 3) avaient le gain de poids vif (2155,00 g), le poids abattu (1855,00 g), le poids sans plumes (1838,33 g), le poids habillé (1455,00 g) et le jarret (112,00 g). Les proportions d'organes ont montré des différences significatives (p <0,05), mais n'ont suivi aucune tendance définie. En conclusion, les oiseaux nourris avec le régime 3 ont donné le meilleur poids de carcasse, et les proportions d'organes n'ont montré aucun effet négatif par rapport aux régimes offerts aux oiseaux. Ainsi, l'inclusion de 28% de gâteau de soja dans un régime à base de céréalesacha s'est avérée supérieure aux gâteau d'arachide et de noix de cajou et elle est donc recommandée.
