Item Body Gain and Carcass Characteristics of Turkeys (Meleagris gallopavo) under Extensive System of Management in the Sudan(2013) Salim Gibril; Rania M. Shamseldin; Osama E. Yassin; Al hafiz A. Hassan; Muzzamil AttaThe objective of this study was to examine the body weight gain and carcass traits of turkeys under the extensive system in the Sudan. 100 unsexed turkey growers of the British United Turkey (BUT Big 6) were kept in an extensive system of management at the University of Bahri Farm from 9 th to 16 th weeks of age. During this period, the birds were fed on an experimental diet of 2958 kcal/kg and 180.0 g/kg metabolizable energy and crude protein contents, respectively. The results showed that the turkey had initial weight of 2.49 ± 0.067 kg, final weight of 5.9 ± 0.255 kg, daily body gain of 66.25 ± 1.530 g/day, weekly feed intake of 1.31 ± 0.080 kg/bird/week, feed conversion ratio of 2.82 ± 0.307 g feed intake/g body gain and total mortality rate of 8%. The turkey also had 78.4 ± 2.776%, 14.87 ± 1.693%, 14.48 ± 2.143% and 35.72 ± 5.937% total dressing out, thigh, drum stick and breast percentages, respectively. No differences (P>0.05) were observed between male and female in the measured parameters. It can be concluded that turkeys can be reared under the extensive system of the Sudan with satisfactory body performance.
