Item Grpwth Performance and carcass characteris of Turkeys(2014) Al hafiz A. Hassan; Salim Gibril; Rania M. Shamseldin; Osama Elshiek YassinItem 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.

BusharaA survey on turkey raising in the Sudan using structured questionnaires and interviews for 25 breeders and 5 dealers, officials of five state ministries and 8 Agricultural Colleges was carried out to know the present status of turkey rearing. Results showed that black at 5.74% was the dominant colour, 69.3% of respondents hatched their replacement flocks, 85.7% were home rearing 66.7% raised less than 30 birds and most breeders used cereals (sorghum and rice) of which sorghum constitute about 70%. Some 50% kept flocks for eggs and meat production, 25% for meat alone, 63.7% marketed live birds, 27.3% as slaughtered and 50% of respondents marketed at any age with customer availability and price being limiting factors. Healthwise 50% vaccinated their flocks and 66.7% received veterinary care and advice. Main problem encountered was feeding, followed by diseases and environmental factors (22.2%). For the majority (75%) manure had no use. No extension services or technical support were offered from all the state ministries. Most colleges included some educational courses on turkey.

Two hundred unsexed Ross hybrid one day old broiler chicks were randomly assigned into 5 groups, 40 chicks each and randomly divided into 4 replicates of 10 chicks each in 5 feed treatments inside an open sided deep litter poultry house. They were fed (0%, 3%, 6%, 9%and 12%) levels. The study results showed significant (P ≤ 0.05) improvement in feed intake, Feed conversion ratio (FCR) weight gain and final body weight by decortications and increasing rate of inclusion of (Pp) progressively. Incorporation of (Pp) at 12 % level followed by 9% gain the best results for all parameters studied but 6% incorporation did not show any significant (P ≥ 0.05) difference from 9 and 12% inclusion rates indicating best option for incorporation. Serum proteins and uric acid were within normal levels for all incorporation rates. Mortality ranged from 2.5-10% being highest at 12% incorporation level. It was concluded from this study that broilers can perform well up to 12% incorporation rate of (Pp) as a substitute to sesame cake.
