Vol 7(11), 77-88

A total of 24 Large White Yorkshire pigs of 2-3 months age were randomly grouped into three treatment (T1, T2, & T3, respectively).In each group there were eight pigs of four replicates. Animals in T1 were kept in deep litter housing system and fed with fermented feeds. Animals of T2 were kept in deep litter housing system and fed with conventional concentrate ration and animals of the T3 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 T1. Feed conversion ratio (FCR) was numerically lower in T1 and T2 compared to T3 group. The carcass characters of the different treatments did not differ significantly but the back fat thickness was lower numerically in the treatments T1and T2.
