Abstract :This study was performed with the participation of 26.22±1.07 kg average weighted 36 singleton lambs. 6 Groups were formed; 3 with IYM (7 g/day) and 3 without IYM. Lambs were kept in individual divisions and given 150 g/day roughage (alfa alfa hay (AH), meadow hay (MH), wheat straw (WS), concentrated feed and water ad libitum. Treatment lasted 70 days in total; temperature and humidity were recorded daily. Fattening performance, carcass parameters and ruminal pH levels were not affected by the treatment (P>0.05). Additive increased the weight of the hearts which were fed with AH (P 0.05). It’s concluded that, temperature and humidity is an efficient environmental factor on the fattening performance and IYM have positive effects on some cell-wall components digestibility and rumen parameters.
