The effect of combined feed supplements (prilled fat, sweetener and toxin
binder) was studied on 24 apparently healthy early lactating rural and urban
maintained Murrah buffaloes. The feeding of combined feed supplement was
carried out for a period of 90 days. DMI, BCS, body weight were recorded at
fortnightly intervals and milk composition was analyzed at weekly intervals.
Blood samples were analyzed for hormones, plasma metabolites and lipid
profile. The supplementation increased (p<0.01) milk yield by 13.6 and 17.0%
in urban and rural Murrah buffaloes with respective increases of 20.14
and14.98% in milk fat (p<0.01). BCS and DMI varied non-significantly (P>0.05)
between the groups. Body weight increased in rural buffaloes in comparison to
urban buffaloes. Plasma GH was higher (p<0.05) before supplementation and
fluctuated non-significantly (P>0.05) during supplementation period. Mean
leptin levels decreased (p<0.05) while plasma estradiol and IgG level
increased during the supplementation period. Plasma progesterone and ghrelin
level varied non-significantly before and during supplementation. Plasma
IGF-1 and glucose levels was more and NEFA level was lower (p<0.05) during
the experiment. Mean HDL, triglyceride and cholesterol concentration
increased (P<0.05) during supplementation than before supplementation. Blood
urea nitrogen and plasma urea level was lower before feeding and increased
during the experiment. The conception rate was more and service period was
less (P<0.05) in urban buffaloes as compared to rural buffaloes. The complete
feed supplementation was highly economical and generated an additional income
of Rs. 114.45/day/buffalo with cost benefit ratio of 1:5. It was concluded
that complete feed comprising of prilled fat, sweetener and toxin binder
augment overall productive performance of rural and urban buffaloes.
