Abstract
An experiment was carried out for six weeks, from April 15 to May 26, 2011, in arid zone of Rajasthan. A total of 180 day old broiler chicks were divided into four treatment groups of 45 chicks which were further subdivided into three equal replicates.
The designation used in the present study were T1, control group without any supplementation. T2 group was supplemented with synthetic vitamin E @ 100 g/ton of feed. T3 and T4 groups were added herbal vitamin E @ 50 g and 100 g/ton of feed, respectively.
The average body weight was found to be significant in all the six weeks. Weight gain was found to be significant in week I, II, III, IV and VI. The average feed consumption was found to be significant in all the weeks.
The effect of vitamin E on feed conversion efficiency was significant (P < 0.05) at the starter stage (week IIII) and highly significant (P ≤ 0.01) at finisher stage (week IV-VI) and on cumulative feed conversion ratio (I-VI weeks). Mortality rate was observed to be non significant.
Higher profits per chick over control, of Rs. 5.81 was found in group T4 followed by T2 Rs. 4.57, T3 Rs. 2.76. The results suggested that feed cost per kilogram live weight gain was reduced by supplementation of vitamin E. Hence, incorporation of vitamin E is beneficial for economic broiler production in moderately high temperature.
