Effect of administration gamma-amino butyric acid on physiological performance of broiler chicks

This experiment was conducted to study the effect of administration {gamma}-amino butyric acid (GABA) on physiology performance of broiler chicks. The following treatments were used: T1:control treatment, T2: the birds were administration 0.2ml 0.4% GABA solution daily, T3: the birds were administration 0.2ml 0.5% GABA solution daily and T4: the birds were administration 0.2ml 0.6% GABA solution daily. The results of the experiment indicated that there were significant differences for the calculating blood lipids .When calculating blood enzymes, there are significant differences between the treatments
