For 47 days 340 broiler chickens, 1 day old, were fed diets containing 0, 5, 10, 15 and 20% extruded full-fat soyabeans (EFFS) corresponding to 0, 5, 10, 15 and 20% substitution of soyabean expeller plus sunflower oil, respectively.
There were no significant effects of the EFFS inclusion levels on live weight gain, feed:gain ratio, mortality rate, weight of carcass, breast fillet, thighs, internal organs (liver, gizzard, spleen and heart), abdominal fat and thigh meat composition of broilers. Soyabean expeller and sunflower oil can be successfully replaced by EFFS up to 15 or 20% in the starter, grower and finisher diets without an adverse effect on the chickens health.
Key words: extruded soyabeans, compound feeds, broiler chickens, sunflower oil
Abbreviations: LW = live weight, EFFS = extruded full-fat soyabeans
