Abstract

This study was conducted to evaluate the effect of three levels of concentrate 2%, 3%, 4% with or without N-carbamylglutamate (NCG) on rumen bacteria and fermentation characteristics in Shami goats. Twenty-four male goats aged 8-10 months with initial weight 32,685 ± 1.52kg divided into six treatments in a 2×3 factorial experiment/ Completely Randomized Design. Individual feeding was used for 70 days. Rumen fluid was sampled at 0, 3, 6h after feeding while jugular blood was sampled after 70 days before morning feeding. Results showed decreasing (P<0.01) of rumen pH and increasing volatile fatty acids (P<0.01) after 3h and 6h of feeding for 3% level of concentrate with NCG. Rumen ammonia increased (P<0.01) after 3h of feeding with NCG. Total rumen bacteria increased insignificantly with superiority 3% level of feeding without NCG and 4% concentrate with NCG. A linear decrease (P<0.01) of blood urea with increasing feeding level with NCG and GPT decreased (P<0.05) with 3% concentrate. In conclusion, it is preferred to feed 3% concentrate and use NCG as additive with urea.
