Abstract

<abstract abstract-type="main" id="jpn12151-abs-0001"> <title>Summary</title> <p>To study the effect of supplementation of tannin degrading bacterial culture (<italic>Streptococcus gallolyticus</italic> strain TDGB 406) on growth performance, nutrient utilization and urinary purine derivatives of goats fed on oak (<italic>Quercus semicarpifolia</italic>) leaves. For growth study, eighteen billy goats (4 month old, average body weight 9.50 ± 1.50 kg) were distributed into three groups of six animals each. The animals of group 1 served as control while animals of groups 2 (T1) and 3 (T2) were given (@ 5 ml/kg live weight) autoclaved and live culture of isolate TDGB 406 (10<sup>6</sup> cells/ml) respectively. The animals were fed measured quantity of dry oak leaves as the main roughage source and <italic>ad libitum</italic> maize hay along with fixed quantity of concentrate mixture. The feeding of live culture of isolate TDGB 406 (probiotic) did not affect dry matter intake and digestibility of nutrients except that of dry matter and crude protein, which was higher in T2 group as compared to control. All the animals were in positive nitrogen balance. There was no significant effect of feeding isolate TDGB 406 on urinary purine derivatives (microbial protein production) in goats. The body weight gain and average live weight gain was significantly higher (p = 0.071) in T2 group as compared to control. Feed conversion efficiency was also better in the goats fed on live culture of TDGB 406 (T2). The feeding of tannin degrading bacterial isolate TDGB 406 as probiotic resulted in improved growth performance and feed conversion ratio in goats fed on oak leaves as one of the main roughage source.</p> </abstract>
