Abstract

Fifteen lactating buffalo at early lactation period were distributed randomly on
three-tested groups (5 animals/group). Three concentrate mixtures were formulated,
first one had no calcium salts of fatty acids (Ca-SFA) and served to be the control
while calcium salts of fatty acids (Ca-SFA) was added to the second and the third
mixture at level of 2 and 4% of total dry matter intake replacing corn grain. Rice straw
was fed to the animals to cover the roughage part of the rations. The obtained data of
this study revealed that, no significant differences were observed among control group
compared with groups fed 2% or 4% Ca-SFA in the apparent digestibility of OM, OM,
CP, CF and NFE. Groups fed Ca-SFA were (P<O.05) higher in AEE digestibility than
the control. No significant differences were observed among Groups fed 2% or 4%
Ca-SFA (P<O.05) in average daily milk production, fat%, protein%, lactose%, TS and
SNF% of the milk compared with control fed group. Feeding Ca-SFA increased
(P<O.05) serum total lipids (TL), cholesterol (Chol.) and trigylcerides (TG). Feeding
dairy buffalo on ration contained Ca-SFA showed reduction in the cost of producing 1
kg milk with 17.3% and 15.5% respectively. From the above obtained results of this
current study it can be concluded that calcium salt of fatty acids made from the wastes
of refining sunflower oil and palm oil can be used as cheep energy sources
supplement or partially substitution of corn grain in ration of lactating buffalo up to 4%
of the total daily dry matter intake without any adverse effects on the performance of
the animals.
