ANALISIS PROFIL PROTEIN DARAH ANAK KAMBING PERANAKAN ETAWAH DENGAN PEMBERIAN PAKAN SUBSTITUSI SUSU SAPI
Abstract: The objective of
this study is to determine the protein profile of pre-weaning kids fed with
cow's milk as a substitute for dam’s milk. The materials used were 18 Etawah
Descendant (PE) kids born the twin at the age of 5-13 days from 3-4-year-old
dams. This experimental design was a completely randomized design with three
treatments with six replications per treatment, namely the control (T0) fed
100% goat’s milk, treatment 1 (T1) fed 50% goat’s milk and 50% cow’s milk,
treatment 2 (T2) fed 100% cow’s milk. The protein profile serum was analyzed by
sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) method,
12,5% of the resolving gel and 3% of the stacking gel were used. The protein
profile of the 5-14 days old PE kids were 19 protein bands with the molecular
weight ranging from 15-160 kDa. The kids fed with 100% goat milk (T0) and those
substituted by 50% cow's milk (T1), it was produced 19 protein bands with
molecular weights ranging from 15 kDa to 155 kDa, while those fed with 100 %
cow's milk (T2), it was produced 17 protein bands with molecular weights
ranging from 13 kDa to 160 kDa. It can be concluded that the dam's milk
substitute using cow's milk at the 50% level does not affect the blood protein
profile of goat kids, while the 100% substitute produces the different number
and types of protein
