The aim of this study was to compare the growth performance of different broiler strains and to evaluate the suitable skip-a-day feed restriction regime at the starter and finisher phases. A total number of 288 day-old broilers of Arbor Acres, Hubbard and Marshall were randomly allocated to four treatments of 96 chicks per strain, with each treatment having three replicates of eight birds. The four treatments are full – fed (control), second, third and fourth week skip-a-day feed restriction. Data on body weight and body linear measurements were recorded on weekly basis to the 8thweek. Results showed that there was significant (p<0.01) effect of strain on body weight, body length, breast girth at the starter and finisher phases. This indicates that there were differences in genetic make-up of the three strains. Arbor Acre strain appeared tolerant to feed restriction and had superior body weight at the starter and finisher phases. Regarding the effect of skip-a-day feed restriction on birds, there was significant (p<0.01) effect on growth characteristics of the birds. Birds full-fed had the highest mean value in body weight, while third week feed restriction recorded intermediate value but better that other feed restriction regimes. It is suggested that for profitable broiler production under tropical conditions, Arbor Acre and third week skip-a-day feed restriction be considered.     L'objectif de cette étude était de comparer les performances de croissance de différentes souches de poulets de gril et d'évaluer le régime approprié de restriction des aliments pour animaux par jour aux phases de démarrage et de finition. Un nombre total de poulets de grillage de 288 jours d'Arbor Acres, Hubbard et Marshall ont été attribués au hasard à quatre traitements de 96 poussins par souche, chaque traitement ayant trois répliques de huit oiseaux. Les quatre traitements sont complets – nourris (contrôle), deuxième, troisième et quatrième semaine skip-a-day restriction de l'alimentation. Les données sur le poids corporel et les mesures linéaires du corps ont été enregistrées sur une base hebdomadaire jusqu'à la 8e semaine. Les résultats ont montré qu'il y avait un effet significatif (p<0.01) de la tension sur le poids corporel, la longueur du corps, la circonférence du sein aux phases de démarrage et de finition. Cela indique qu'il y avait des différences dans la constitution génétique des trois souches. La souche Arbor Acre semblait tolérante à la restriction de l'alimentation et avait un poids corporel supérieur aux phases de démarrage et de finition. En ce qui concerne l'effet de la restriction d'alimentation par jour sur les oiseaux, il y a eu un effet significatif (p<0.01) sur les caractéristiques de croissance des oiseaux. Les oiseaux nourris à part entière avaient la valeur moyenne la plus élevée en poids corporel, tandis que la restriction de l'alimentation de la troisième semaine enregistrait une valeur intermédiaire, mais mieux que les autres régimes de restriction des aliments pour animaux. Il est suggéré d'envisager une production rentable de poulets de grillage dans des conditions tropicales, arbor acre et restriction d'alimentation de troisième semaine par jour.

Continuous genetic selection and improvement in nutrition have led to a very fast growth rate in modern strains of broiler chickens. Metabolic disorders such as ascits, sudden death syndrome and leg problems are related to a rapid early growth rate in poultry, especially in broilers, and their incidence can be decreased by slowing early growth. The use of management tools to reduce metabolic disorders that rely primarily on decreasing feed consumption, The feed restriction programs is on of the main techniques in growth curve manipulation for increasing production efficiency in broiler chicken in alleviate the incidence of some metabolic disorders and can be used to reduction the unfavorable effects of fast growth rate in broiler chicken production industry, and could be profitable in broiler chickens production efficiency. This article implicated on new findings in about different feed restriction programs effects on these problems in broiler chickens.

Purpose of researches in feed restriction area is improvement of feed efficiency, decrease of carcass fat content and abdominal fat pad size (Plavnik and Hurvitz,1991).Birds after early life feed restriction have less maintenance requirements due to decrease of heat increment and decrease of basal metabolic rate and specific dynamic action of food (Forsum et al.,1981).In many investigations, compensatory growth have not observed (Summers et al.,1990).It seems administration of Thyroid hormone after feed restriction can induce compensatory growth. The objective of the present study was to investigate the effect of early feed restriction and L-Thyroxin administration after early feed restriction on compensatory growth in broiler chickens.
