Growth, Efficiency of Feed Utilization and Economics of Different Rearing Periods of Turkeys Mukesh Karki

Abstract

The present study on body weight and feed efficiency for growth was carried out on 112 turkey
poults from day of hatch to 28 weeks of age during May to November 2002 at Poultry Research
Unit of Regional Agricultural Research Station (RARS)-Parwanipur. Layer starter ration
supplemented with 6% fish meal + 0.3% lysine + 0.125% methonine was fed up to 8 weeks of
age, then after layer finisher diet was fed. The body weight, feed consumption was observed at 4
weekly interval and feed efficiency and economics of rearing period in terms of income over
feed and poults cost was calculated. Significant increase in body weight was recorded up to 28
weeks in male and 20 weeks in female. Male turkey had significantly higher body weight than
that of female in all ages. Feed efficiency is best at earlier age but up to 16 weeks it is 3.77 for
male after that it detoriates progressively. Male turkey exhibited better feed efficiency than that
of female for all weeks. Significantly higher return per bird was obtained from male than that of
female in all age. The profit per bird for both male and female was found maximum in 16 weeks
of rearing, followed by 20 weeks and 24 weeks. Therefore, instead of waiting for highest body
weight, it is better to sell turkey at 16 to 20 weeks of age to take maximum advantage of higher
weight gain, higher efficiency of feed utilization and higher profit.
