Animals in T 1 were kept in deep litter housing system and fed with fermented feeds. Animals of T 2 were kept in deep litter housing system and fed with conventional concentrate ration and animals of the T 3 groups were under conventional housing along with conventional concentrate feeding system. Feeds and litter materials were fermented with Lactobacillus acidophilus. The data on growth, feed utilization, carcass characteristics were recorded upto 24 weeks of age in three treatments at every fortnightly (FN) intervals. Live body weight and average daily weight gain (ADG) were not affected by deep litter housing and Effective Microbial (EM) technology. However, average daily feed intake (ADFI) was significantly (P<0.05) lower in T 1 . Feed conversion ratio (FCR) was numerically lower in T 1 and T 2 compared to T 3 group. The carcass characters of the different treatments did not differ significantly but the back fat thickness was lower numerically in the treatments T 1 and T 2.
