Abstract :

This study was aimed to investigate the effect of  replacing  soybean  meal (SBM) by jojoba meal treated with Lactobacillus Acidophilus and Tricoderma Ressie on broiler performance. One-day old 360 unsexed Ross 308 broiler chicks were distributed into eight equal experimental treatments. The chicks in the first experimental treatment was fed control diet (T1), whereas, those in treatment 2 (T2), 3 (T3) and 4 (T4) fed diets containing  jojoba meal treated by Lactobacillus Acidophilus at the level of 5, 10 and 15%, while birds in treatment 5 (T5), 6 (T6) and 7 (T7) fed diets containing jojoba meal treated by Tricoderma Ressie at the level of 5, 10 and 15%, with replacing of soya bean protein in the diets. The birds in treatment 8 (T8) fed diet containing untreated jojoba meal. Experimental period lasted for 6 weeks. Body weight, feed consumption, feed conversion ratio and carcass traits were measured during the experiment period. The highest feed consumption was noticed in T4, while the lowest one was recorded in T8. During the experimental period (0-6 weeks), control, T7 and T2 gave better feed conversion ratio.

Conclusively, it can be concluded that replacing soybean meal with treated jojoba meal biologically up to 5% could be useful for performance of broiler chicks.
