The effect of different levels of rapeseed meals on broiler chick performance
In order the evaluation of different levels of rapeseed meals on broiler chick performance, the experiment was arranged in a randomized completely design with a factorial arrangement (4*2) and three replications. Four levels of rapeseed meals replacing to soybean meals including 0, 40, 60 and 80 percent (factor A) and two strains of broiler chick were including Arian and Ross (factor B). Broilers were growing to 56 days of age. The characteristics under investigation were average daily gain, feed conversion ration, moisture fecal (21, 42, and 56 days of age) and T3 and T4 Thyroids hormones (40 and 56 days of age) in each pen two males and females. At the end of trail one male and female of each pen were selected. The samples killed and dressing percentage heart, pancreas, liver, spleen, proventriculus, gizzard, gall bladder and intestinal weights were determined. The results indicated that 60 ％ rapeseed meals replacing to soybean meals for the feed conversion ratio and average daily gain were better than the other groups. The best body weight and dressing percentage related to group which had to 40 ％ rapeseed meal.
