THE UTILIZABLE EXPERIMENTATION OF RAPESEED OIL RESIDUES IN BROILER RATION

1000 Baoxing broilers aged two weeks were divided into five groups randomly. Th-ere was no significant difference among all treatments when the rapeseed oil residues(ROR) were added to the broiler rations from the third week to the fourth week.From the fifth week to seventh week, certain levels of ROR in the rations showed aneffect like feeding fat. The supplementary level of 2% ROR Showed that the greatesteffect was on broiler's daily gain. The average daily gain in 2% ROR group was 47. 35g.There was significant difference between the two groups (P<0.01), The consumptionof protein and energy in 2% ROR group is by 14% and 12. 98% lower than those incontrol group. The carcasses from the experemental groups during the age of 49 dayswere not any pathological change. The experimental results showed that ROR could beused directly in broiler's rations.
