Effet de deux modes de distribution de l'aliment (Ad libitum et Skip-a-Day) sur les performances chez le poulet de chair.

Abstract

To carry out a study on the influence of the two modes of distribution of the food (Ad libitum and Skip-a-Day) on the growth performance of the broiler, we used two lots, -The reference batch (Witness) consumes ad libitum a balanced food -Lot 2 consumes the same regimes as the batch Control, but it is fed only periodically (Skip-a Day). The main parameters evaluated were: Food consumption; Weight change, consumption index, mortality rate, carcass yield. At the end of the experiment, the best live weight was recorded for lot1 with 3257g / subject. The best yields calculated at the 34th and 42nd days of age were also recorded for lot 1 with a value of 76.70%. It was found that the distribution mode of the skip-a-Day food has an impact. on the weight of faith, where the most important weight of faith was recorded in lot2 with 82.74g. In addition, this type of distribution also affects the weight and size of the crop, where the highest values were recorded in lot2.
