Abstract: A growth trial of 90 days (March-April) was conducted on 18 female Corriedale sheep at Sheep Research Station, Shuhama, Srinagar (SKUAST-Kashmir), to study the effect of feeding fungal treated paddy straw based complete feed. The studies indicated no significant (p≤0.05) differences between the experimental groups T1, T2 and T3 in DMI and OMI, however numerically the values were highest in T3, followed by T2 and T1. The digestibility coefficients of DM, OM, CP, EE and CF in T3 were significantly (p≤0.05) higher as compared to T1 and T2 whereas the digestibility coefficients of NDF, ADF, NFE, hemicellulose and cellulose in different experimental groups were statistically non-significant (p≤0.05), however numerically the values were highest in T3 group followed by T2 and T1. No significant (p≤0.05) difference was observed in the overall average body weight of animals in different groups though the body weight of T3 group was highest followed by T2 and T1. The periodical ADG and net weight gain in T3 was significantly higher than T1 whereas, periodical average ADG and net weight gain of T2 was non-significantly (p≤0.05) related to both T1 and T3. The average periodical FCR in T1 was significantly (p≤0.05) higher than that of T2 and T3 whereas the values in T2 and T3 could not reach statistical significance. Effect of treatments on rumen pH and NH3-N were found non-significant while as TVFA, total nitrogen, TCA-ppt. N and NPN in groups T2 and T3 were found significantly (p≤0.05) increased as compared to the control. Significant (p≤0.05) effect of period irrespective of the treatment was observed on all the rumen parameters.
