| dc.description.abstract | In the present study, six Murrah buffalo bulls (7 yrs. 304.52 ± 8.64 kg) were randomly selected and fed Zuri fodder. The Zuri fodder was evaluated for its chemical composition, CNCPS fractionation, in vitro digestibility of DM and OM at different stages (15, 20, 25, 30 and 35 days) of harvest, rumen fermentation pattern, nutrient intakes, utilization and balance in buffalo bulls. The chemical composition showed highest CP (16.95 %) at 15 days of harvest and lowest (12.28 %) at 35 days of harvest but the fiber fractions were inversely proportional to the crude protein content at different stages of harvest. The CNCPS fractionation of Zuri fodder revealed higher CB1 and CB2 fractions and lower CC fraction harvested at 15 days compared to the fodder harvested at 35 days. Similarly, the protein fractions PA and PB3 were higher and PC was lower at 15 days of harvest indicating higher degradable portion of carbohydrate and protein in Zuri fodder. The oxalate content (%) of Zuri fodder was 2.96, 2.55, 2.23, 1.89 and 1.65 at 15, 20, 25, 30 and 35 days of harvest, respectively, and it decreased linearly with the increase in days of harvest. The in vitro digestibility (%) of DM and OM in Zuri fodder decreased (P<0.05) linearly from 15 to 35 days of harvest. Higher DM and OM (%) digestibility was observed at 15 days (72.23 and 78.46) and lowest at 35 days of harvest (59.13 and 67.94), respectively. Significant (P<0.05) differences were observed in in vitro digestibility between all stages of harvest. Rumen fermentation studies conducted in fistulated buffalo bulls revealed that rumen pH values were highest at 0 h and declined to minimum by 6 h post feeding, while TVFA reached peak at 6 h post feeding and NH3-N reached peak at 2 h post feeding and later followed a decreasing trend. The nutrient intakes of proximate and cell wall constituents by buffalo bulls fed Zuri fodder expressed as kg/day, % BW and g/kgW0.75 met the requirements for maintenance (ICAR, 2013). Voluntary feed intake (kg) on fresh basis is 41.47 and DM intake (% BW) is 2.25 in buffalo bulls fed Zuri fodder. The digestibility coefficients (%) of gross nutrients and fibre fractions showed better digestibilities. All the buffalo bulls were in positive N, Ca and P balance. The average DMI (kg/d) of buffalo bulls (6.85) met the requirements. The DCP (%) in fodder consumed (8.46) is more than the requirement for maintenance of the buffalo bulls. Furthermore, the DM, DCP, TDN and ME intakes per kgW0.75 in buffalo bulls fed Zuri fodder (93.92, 7.95, 46.77 and 0.17), respectively, were higher than the values recommended by ICAR (2013) and Kearl (1982) standards. Based on results of the present study, it is concluded that feeding of Zuri fodder showed higher in vitro digestibilities of DM and OM. Further, in vivo studies revealed better DM intake and digestibility of gross nutrients and fibre fractions. The carbohydrate and protein fractions of Zuri fodder showed higher degradable fractions. The oxalate content is higher in early stages compared to mature fodder. Hence, it is recommended that Zuri fodder can be used for feeding ruminants and can be harvested at 30 days for animal feeding without any adverse effects. | en_US |
