Present study was carried out to study the eff ect of solid state fermentation (SSF) biomass on growth performance of Surti growing kids. Fourteen kids (4-7 months age) weighing around 9 kg, were randomly divided in two groups of 7 each. All the kids were fed rations containing 50 % jowar straw and 50% compound concentrate mixture. Animal of group 1 served as control and were off ered TMR (total mixed ration) without biomass, while animals of another group were off ered solid state fermentation (SSF) biomass @ 4% in the TMR, All the experimental kids were weighed at weekly intervals and body measurements (height at wither, body length and heart girth) were taken fortnightly in the morning for two consecutive days before feeding and watering for the entire experimental period of 90 days. Average total gain (ATG) during 90 days experimental period was 4.47 and 5.23 kg with average daily gain (ADG) of 46.53 and 54.42 g in control and treatment groups respectively. The results revealed an improvement of about 17% in average daily gain though remained statistically similar between the two groups.
