Performance of Turkeys Under Extensive and Semi - intensive Systems of Management in Khartoum State

Abstract

An experiment was carried out to determine and compare the
performance traits of turkeys under semi-intensive and extensive systems
of management in Khartoum State, Sudan. A commercial breed of turkey
(BUT Big 6) was used. Birds were kept in an open-sided, deep litter
poultry house (semi intensive system) and fenced enclosures (extensive
system) from week 17 to weeks 24 and 28 and fed on turkey finisher and
supplement diets, respectively. Parameters assessed were feed intake,
body weight, body weight gain, feed conversion ratio (for each feed),
mortality and cost and profit. Results of feed intake indicated a consistent
increase with increase in age in both systems of management up to week
22 followed by a consistent decrease in feed intake up to the end of the
experiment at week 28. Body weight increased with increase in age in
both systems of management up to week 24 followed by a slight increase
up to week 28. Turkeys kept under semi-intensive system of management
consumed higher amounts of feed, gave heavier finishing weight, average
weight gain, heavier carcass weight and higher profit than those kept
under extensive system up to week 24 and lower mortality percentage and
profit from week 25 to week 28. No difference between treatments was
found in dressing percentage and wholesale cuts. The study concluded
that the semi- intensive system is better for turkey production up to week
24.
