Abstract
The study was carried out using 10% aqueous and ethanolic extract of Emblica officinalis fruit powder
,Acacia nilotica leaves, Psidium guajava leaves to assess in vitro rumen fermentation parameters. The in vitro trial
was conducted by taking different concentrations @ 0.2 ml, 0.5ml, 1ml and 2 ml of plant extracts with substrate
media containing rumen fluid. After 6 and 24 hours of incubation pH, total gas production, ammonia- nitrogen,
TVFA and total nitrogen was measured. The results revealed that the total gas production decreased in plant
extract supplemented samples with respect to control. Total nitrogen production increased in aqueous E. officinalis
and A. nilotica plant extract supplemented groups and increase in TVFA was observed in all plant extract
supplemented samples. Ammonia- nitrogen production does not vary significantly, indicating no change in NPN
degradation due to supplementation of different plant extracts at different concentration except A. nilotica (EE). In vivo rumen fermentation experiment included 3 months feeding trial, where 2 fistulated male buffalo calves were
selected. In growth and biochemical studies, 12 male buffalo calves were divided into two groups of six animals in
each group. The animals in treatment group were fed as per the control along with 30g of E. officinalis powder
selected on the basis of in-vitro results. Growth parameters and haemato-biochemical parameters were analyzed in
plasma samples at 0, 45 and 90 days. E. officinalis feeding indicated a promising effect on ruminal fermentation by
enhancing VFA production whereas no significant effect was observed on growth parameters. Feeding of E.
officinalis powder affects the nutrient metabolism, haematological parameters indicated by a significant increase in
TEC and Hb concentration. Regarding biochemical parameters total protein and albumin concentration increased
significantly (p < 0.05) in treatment group at 45day and 90 day. Cholesterol and LDL concentration increased
significantly (p < 0.05) in both treatment and control group but they were in normal range.
Considering all together, feeding of E. officinalis powder is likely to affect the rumen fermentation and haemato biochemical parameters in buffalo calves without any adverse effect on nutrient metabolism, growth and
performance of buffalo calves.
