KERAGAMAN GEN K-KASEIN DAN HUBUNGANNYA DENGAN PRODUKSI DAN KUALITAS SUSU PADA DOMBA DI UNIT PENDIDIKAN DAN PENELITIAN PETERNAKAN (UP3) JONGGOL
ABSTRACT: The objectives of
this study were to identify polymorphisms in ovine K-casein gene exon 4 and its
association with milk yield, percentage of protein and milk fat in sheep under
extcnsif management at JASTRU (Jonggol Animal Studies Teaching and Research
Unit) farm, Fact. of Anim Sci, Bogor Agric. University. The 83 blood sample
from ewes which have record of milk production were used to determined
polymorphism by using PCR-SSCP (Polymerase Chain Reaction-Single Strand
Conformation Polymorphism) methode. The research activities were carried out
through blood collection, DNA isolation, and fragment DNA amplification by PCR
and separation in electrophoresis with silver staining. Electrophoretic pattern
(PCR-SSCP) revealed th rce types of K-casein gene were dcsignitcd A, Band C
type. The highest proportion was A type 69.57% and followed hy B 28.99% and the
lowest C 1.45%. The were no significant effect of types of of K-casein gene on
milk production and milk quality (percentage of protein and fat) in local sheep
from Jonggol.
