Abstract: 150 one-day-old broilers were divided into five groups randomly which were composed of three groups ad lib. and two zinc-sufficient pair-fed groups. The three groups ad lib. were fed respectively the different experimental diets which were supplemented with three levels of dietary zinc (0, 5, 80 mg/kg) and 3 000 IU/kg of dietary vitamin A in the zinc-deficient semi-purified diet which contained 4.67 mg/kg zinc and was mainly made of corn starch and low zinc soybean meal. In addition, two zinc-sufficient pair-fed groups with the zinc-deficient groups were restricted to the average consumed by zinc-deficient groups in order to further explore the effects of feed intake and growth restriction as a result of zinc deficiency in diet on vitamin A metabolism in broilers. The results indicated that zinc deficiency would result in a significant depression of feed intake and growth and serum zinc and vitamin A concentrations in broilers. A significant decrease of serum vitamin A concentration was a result of feed intake and growth restriction resulting from zinc deficiency when dietary zinc level was 9.67 mg/kg. However, significant decrease in serum vitamin A level was a result of not only zinc deficiency but feed intake restriction resulting from zinc deficiency when dietary zinc level was 4.67 mg/kg. Feed intake restriction would result in an apparent decrease in serum vitamin A concentrations in broilers, but it had no effects on serum zinc concentrations.
