Abstract

The overall cost of broiler production mostly depends on the cost of feed, and this is so exorbitant as to threaten the sustainability of the enterprise. It is therefore necessary to identify means of reducing cost to increase the farmer's income. Likewise the production of lean carcass for consumer's wellbeing is paramount in broiler production. This study was conducted to investigate the effect of feed restriction with or without enzyme supplementation on performance, carcass characteristics, and cost benefit of broiler chickens for a period of fifty-six days. Three hundred, one day-old Marshal Broiler chicks were used in a 3×2 factorial experimental layout to test the effect of feed restriction (FR) at 0, 15, and 30% of ad libitum feeding with two levels of enzyme supplementation (ES) at 0 and 1000ppm. Data were collected on feed intake, weight gain, feed: gain ratio, mortality, carcass characteristics and cost benefit ratio. Data obtained were subjected to one way analysis of variance and significant mean separated. ES however improved the value obtained for these performance indices. Level of feed restriction had significant effect (P<0.05) on live weight, with (2115g) for bird on 0% level of restriction, followed by (2066g) for 15% and (1880g) for 30% level of feed restriction respectively. Likewise, the abdominal fat reduces as the level of restrictionn increases. Hence, enzyme supplemented diet performed better than those chickens without enzyme inclusion in their diet. In conclusion, the trials showed that as the level of feed restriction increases, feed cost /kg reduced and abdominal fat was reduced while enzyme supplementation enhanced feed utilization and improved the performance of the broilers subjected to feed restriction.

 

 

Le coût global de la production de poulets de chair dépend principalement du coût de l'alimentation, et cela est si exorbitant qu'il menace la durabilité de l'entreprise. Il est donc nécessaire d'identifier des moyens de réduire les coûts pour augmenter le revenu de l'agriculteur. De même, la production de carcasses maigres pour le bien-être du consommateur est primordiale dans la production de poulets de chair. Cette étude a été menée pour étudier l'effet de la restriction alimentaire avec ou sans supplémentation enzymatique sur les performances, les caractéristiques de la carcasse et les coûts-avantages des poulets à griller pendant une période de cinquante-six jours. Trois cents poussins Marshal Broiler d'un jour ont été utilisés dans une configuration expérimentale factorielle 3 × 2 pour tester l'effet de la restriction alimentaire (RA) à 0, 15 et 30 % de l'alimentation ad libitum avec deux niveaux de supplémentation enzymatique (SE ) à 0 et 1000 ppm. Des données ont été recueillies sur la prise alimentaire, le gain de poids, le rapport alimentation/gain, la mortalité, les caractéristiques de la carcasse et le rapport coûtbénéfice. Les données obtenues ont été soumises à une analyse unidirectionnelle de la variance et une moyenne significative séparée. SE a cependant amélioré la valeur obtenue pour ces indices de performance. Le niveau de restriction alimentaire a eu un effet significatif (P<0,05) sur le poids vif, avec (2115g) pour l'oiseau un niveau de restriction de 0%, suivi de  (2066g) pour 15% et (1880g) pour un niveau de restriction alimentaire de 30% respectivement. De même, la graisse abdominale diminue à mesure que le niveau de restriction augmente. Par conséquent, l'alimentation enrichie en enzymes a donné de meilleurs résultats que les poulets sans inclusion d'enzymes dans leur alimentation. En conclusion, les essais ont montré qu'à mesure que le niveau de restriction alimentaire augmente, le coût de l'alimentation/kg diminue et la graisse abdominale diminue tandis que la supplémentation en enzymes améliore l'utilisation des aliments et améliore les performances des poulets soumis à une restriction alimentaire.
