Effect of enzyme and vitamin supplementation on physio-biochemical parameters in broiler chickens

Abstract

The present research was carried out on broilers to study the effect of oral administration of enzymes and vitamins on growth, haematological parameters and biochemical parameters in the Department of Physiology, Bangladesh Agricultural University for the period of 21 days from 15th January to 5th February 2007. A total of 20 broiler birds of 20 day old were divided into four equal groups as A, B, C and D. Group A was maintained as control and was fed only with commercial broiler ration through out the experimental period.  Group B was treated with enzymes @ 1 gm per litre of drinking water, group C was treated with vitamins @ 0.5 gm per litre of drinking water and group D was treated with enzymes and vitamins combinedly at the rate of above mentioned dose. Body weight was recorded at 7 days interval up to the end of the 21 days of experimental period and the birds were sacrificed on the final day of experiment to collect blood sample for haematological (TEC, Hb, PCV and ESR) and biochemical study (SGOT and SGPT). Body weight was increased significantly (p <  0.01) in all the treated groups compared with the control group and highest was recorded in group D. TEC, PCV and Hb content increased significantly (p < 0.01) in the treated groups as compared to that of control group but ESR, SGOT and SGPT values decreased significantly (p < 0.01) in all the treated groups as compared to that of control group. The result reveals that use of enzymes and vitamins is an effective way of getting best result in terms of body weight gain and haemato-biochemical profiles in broiler birds.
