Effect of Substitution of Vicia Sativa Raw and Treated Seeds as A substitute for Soybean Meal on Productive Performance of Broiler Chickens

The study was carried out using 405 chicks with a one-day-old, type Rose 308. The birds were randomly distributed to nine experimental treatments, with three replicates per treatment (15 birds/replicate). The birds were fed ad libitum during the 42-day trial period, 9 diets were used for study in the starter and 9 diets in the finisher period, as protein source used the Vetch 12.5% and 25% as an alternative to soybean meal, Vetch was treated by soaking in water or acetic acid (1% concentration) or by adding activated charcoal 50 gm / 100 kg diets. The results of the 21-day starter level showed a significant difference (P < 0.05) for live body weight, weight gain, consumed feed, and feed conversion ratio between control treatment and Vetch treatments 12.5% and 25% soaked water, acid and activated charcoal. While there were no significant differences in Mortality% in the period 21 days, in the finisher period (22-42 days), the results showed significant differences (P
