Abstract: The present paper was conducted to investigate the associative effects(AE) between corn straw and different N source using gas production in vitro. Soybean meal and urea was used as main CP source and corn straw as NDF resource . The results indicated that the significant positive effect was observed among corn straw and soybean (9% to18% CP) and the maximum value was detected when CP level was 15% at 24 h. As for straw and urea, significant positive effect presented at 8% to 15% CP and the maximum value appeared at 12% CP. 

Key words: associative effect; corn straw; urea; soybean meal
