Penggunaan Onggok sebagai Sumber Energi dalam Ransum Sapi
ABSTRACT: The dairy farmer in
the rural village, usually use rice brain and coconut meat kernels as the
energy source, although coconut meat kernels is less palatable and too
expensive. It is, therefore, important to seek for the other materials which
are locally available and inexpensive. An experiment had carried out, using
five lactating dairy cows in a Change Over Design as long as five periods. Each
period lasted for 21 days, consisted of 14 days preliminary and seven days
observation period. The animal function as column and the period as row, so
that its 5 x 5 Latin Square. The treatment tested are five substitution levels
of coconut meat kernels by cassava meal residues of 5, 7.5, 10, 12.5 and 15
percent dry matter ration respectively. The variables measured were : (1)
ration digestibility and essential minerals balance; (2) daily milk production
and milk composition; (3) rumen fermentation product. Based on the analysis of
variance of all variables measured the experiment suggested that cassava meal
residues can be used as the energy source to substitute coconut meat kernels in
kernels in lactating dairy cattle ration of 5 up to 15 percent dry matter
ration, without causing physiological disorder moreover, increases the milk
composition.
