Abstract
This study had been conducted in the animal resources department, college of agriculture, university of Anbar. eshnan (seidlitzia rosemarinus) used in order to reduce undesirable effects of Flatoxine in comparison with some biological cures such as saccharomyces and Iraqi probiotic. This experiment had been done within 24 weeks (168 days) for the period from 17/1/2013 till 3/7/2013. Two hundred broiler breeder chickens (Ross 308) used, starting with the age of 27 weeks and finishing by 50 weeks at the end of the 168 days.
The chickens grew up in coops and the process of artificial insemination had been done twice in the week. Experimental treatments were T1 / ration without any addition as (control), T2/ ration contaminated with 1.5 mg aflatoxin B1/kg feed +2% Shinan, T4/ ration contaminated with 1.5 mg aflatoxin B1/kg feed +4% eshnan, T5/ ration contaminated with 1.5 mg aflatoxin B1/kg feed +2 kg probiotic / ton feed, T6/ ration contaminated with 1.5 mg aflatoxin B1/kg feed + 50% probiotic fermentation daily and T7/ ration contaminated with 1.5 mg aflatoxin B1/kg feed + 1 kg saccharomyces / ton feed. Two shots of baby chicks had been breaded. The first broiler breeder age were 33 weeks (7 weeks of the experiment's age).
The second was at 47 weeks (20 weeks of the experiment's age).They weight the chicks in earth treatment. Each treatment had been divided into three replicates, each replicate contain six chicks. The body weight, weight gain, feed and feed consumption had been studied. Then, at the end of growing Perrier, relative growth rate and production efficiency factor had been calculated.
The results showed that adding (4%) of eshnan to the diets contaminated breeders with Aflatoxin led to significant increase (P<0.05) in the mean weight gain, body weight and relative growth rate in comparison to the Aflatoxin treatment. There was not any significant differences between the treatments in feed consumption, feed conversion coefficient, mortality rate and production efficiency factor in the first experiment. There was not any significant differences in all traits studied during 42 days of the second experiment.
