Abstract

BACKGROUND: The antagonistic effect of inorganic mineral sources and the high cost of organic minerals have created the need to find alternatives to these two common forms. The introduction of a new inorganic source of zinc hydroxychloride prompted this study to compare its effects at different levels for broiler chickens raised in high environmental conditions.
OBJECTIVES: The aim of the present study was to investigate the effect of zinc hydroxychloride on functional, serum and blood traits, zinc storage in tibia, liver, breast muscle and the effect on ascites in reared broiler chickens..
METHODS: In this experiment, 300 broiler chickens (Rass strain) from 1 to 22 days of age were used. Experimental treatments included basal diet and 25, 50 and 75 mg zinc hydroxychloride per kg added to the control diet. Body weight parameters, feed intake and blood-serum parameters and sampling of relevant tissues were investigated to measure zinc storage and examine intestinal morphology.
RESULTS: The effect of the addition of zinc hydroxycloride on the feed conversion coefficient and growth performance over the entire breeding period has been meaningful and positive. The percentage of carcass yield in experimental treatments compared to the group saw a significant increase and decrease in liver weight (p<0.05). In serum, zinc and nitric oxide concentrations increased significantly, while Malone dialdehyde, hematocrit, and heterophile-lymphocyte concentrations decreased significantly (p<0.05). Increased levels of zinc hydroxy in the ration saved as much of this mineral as possible in breast, liver and bone tissue (p<0.05).
CONCLUSIONS: The results of this study indicate the high efficiency of zinc hydrochloride in improving the growth and health of chickens, along with the economic potential for the poultry industry, and ultimately this substance can play a significant role in lowering pulmonary blood pressure due to its antioxidant properties.
