ABSTRACT
This study was conducted to assess the performance and economical benefits of use of enzyme supplementation in an intensive feeding system in Beetal x Dwarf (crossbred) male goats. The fibrolytic enzyme produced from Chaetomium thermophile (DG-76), contained 5.8±0.1 U/ml, 8.3±0.2 U/ml, 6.2±0.2 U/ml, 170±2.2 U/ml and 2.2±0.02 mg/ml of filter paper (FP)-ase, CMC-ase, β-glucosidase, xylanase and extra cellular protein, respectively. The enzyme was mixed @ 1% v/w in total mixed ration (TMR) containing 15.14% CP, 20.75% ADF and 35.24% NDF which was offered for 60-d to two similar groups of 10 in each male goats weighing Control 33.42±1.1 kg and fibrolytic enzyme supplemented (FES) group 34.02±1.13 kg. There was a significant improvement (P=0.0001) in weight gain in enzyme supplemented than control group (5.01 vs 4.1 kg). Average daily live weight gain (ADLWG) was found to be 83.49 g in FES compared with 68.33 g in control and was statistically significant (P=0.0001). There was a non-significant (P=0.2875) decrease of 3.75% in feed intake in control group compared with FES, however, the feed conversion ratio (FCR) varied significantly (P=0.0008) and was 15.08% lower in FES than the control. Overall the enzyme supplementation resulted in 31.25% increase in net profit compared with the control group.
