摘要

In order to evaluate the effect of acetic acid on growing and laying performance of Japanese quail (JQ), 180 15-day-old JQ were divided into 4 groups. During the growing (15-42 days of age) and laying (43-84 days of age) periods, the groups fed the same basal diets supplemented with 0, 1.5, 3 and 6% of acetic acid. Each diet was fed to five replicates of 9 JQ (3 males:6 females) during the growing period. During the laying period, 128 birds were housed in 32 cages (4 birds per cage, 1 male and 3 females, 8 replicates per treatment). Birds were housed in wire cages (46Lx43Wx 20H cm) in an open room. Acetic acid supplementation at 3% In the diets significantly increased the growth and laying rate and the Haugh unit score. The liver percentage significantly decreased with acetic acid at 6%. Acetic acid at 3% significantly increased hemoglobin concentrations at 6 weeks of age and increased weight of day old chicks hatched. Acetic acid affected the immune system as manifested by an excess of cellular reactions in the intestine as well as lymphoid hyperplasia in the spleen tissue. Degenerative changes In the covering epithelium of the intestinal villi were noted at the 6% concentration of acetic acid. Hepatocyte vacuolation and fatty changes were also observed at this concentration of treatment. In conclusion, 3% acetic acid may beused as a feed supplement for JQ during the growing and laying period to improve the productive performance.
