The Effects of Stocking Density on Broiler Performance

Abstract

The performance traits of broilers reared in different stocking density groups were investigated. Data were obtained from 910 broilers housed in litter-type pens at densities of 12.5 (1), 15 (2), 17.5 (3) and 20 (4) broilers/m2. Each pen had 14 m2 floor space. More than 60% of the broilers were selected by random sampling and were weighed on the 21st, 35th and 49th days of investigation. Body weight estimates of the 1, 2, 3 and 4 broilers/m2 density groups were 1634.3, 1511.7, 1506.5, and 1503.9 g respectively. Mortality rates were 6.2, 7.1, 7.7 and 6.4% for the same groups respectively. Feed efficiency values were estimated to be 1.97, 2.06, 2.07, and 2.09 kg at 49 days of age for the same groups respectively. The diffeences between the values of the groups with respect to body weight at the 35th day were not statisticaly significant. The first group had higher body weight mean estimates than the other groups at the 49th day (P
