TAILIEUCHUNG - Study on different feed form on the performance of broilers chicken

In this study, it was conducted to evaluate the effects of three various physical diet forms (whole pellet, whole crumble, and mix crumble and pellet) on broilers performance. It was performed by using 150 broilers (male and female mix) from commercial Arbor Acres breed in a completely randomized design with 3 diets by 2 replications (25 chickens per each replication). | Nguyễn Hƣng Quang và cs Tạp chí KHOA HỌC & CÔNG NGHỆ 77(01): 55 - 58 STUDY ON DIFFERENT FEED FORM ON THE PERFORMANCE OF BROILERS CHICKEN Quang N. * and Ebrahimi R2 1 College of Agriculture and Forestry - Thai Nguyen University 2 Ramin University of Agriculture and Natural Resources ABSTRACT In this study, it was conducted to evaluate the effects of three various physical diet forms (whole pellet, whole crumble, and mix crumble and pellet) on broilers performance. It was performed by using 150 broilers (male and female mix) from commercial Arbor Acres breed in a completely randomized design with 3 diets by 2 replications (25 chickens per each replication). Daily gain, feed intake and FCR were measured in whole period, furthermore, carcass mean, breast, leg meat, abdominal fat, liver, and gizzard were measured and analyzed at end of the experiment. Body weight was not significant different among the tests. Feed intake was highest in the pellet groups. FCR in the crumble groups was higher than that of the other groups. The results indicate that the physical form of the diet had a significant effect on abdominal fat, which was highest in broilers that fed with pellet diet. Keywords: Particle size, performance, broiler chicken, body weight, FCR INTRODUCTION In poultry diets, cereal grains such as yelow corn, rice, wheat are the primary energy source. Therefore, not only must producers be concerned about the composition of the grain, but also how it is processed so the animal may fully utilize the nutrients. Researches shown that the physical form of diets and feed particle size have a great effect on poultry yield (Behnke and Beyer, 2004) [3]. The effects of particle size on feed quality and quality of poultry has been researched in a number of settings (Behnke, 1994) [2]. Small particle size increases the surface area of the grain, thus allowing for greater interaction with digestive enzymes. It also improves the ease of handling and the .
