Hubungan Produksi Susu Berdasarkan Grade MPPA dengan Performa Reproduksi
Abstract: The aim of this
study was to determine the potential effect of milk production based on Most
Probability Producing Ability (MPPA) on reproductive performance. The secondary
data of body condition score (BCS), reproductive traits and milk production
were collected from Baturraden Breeding Center. Identification of FSH sub unit
beta Gene polymorphisms were conducted by polymerase chain reaction and
restriction fragment length polymorphism (PCR-RFLP) method. Milk production
data was analyzed with formula repeatability (r), heritability (h) and Most
Probable Producing Ability (MPPA). The data were also analyzed using
correlation and ANOVA (GLM). The results showed that repeatability and
heritability of milk production values were 0,84 and 0,4. Gen FSH sub-unit beta
was monomorphic fixed to AB genotype and had no effect on the ability of milk
production and reproductive performance. BCS values had been affected
significantly on milk production based
on grade of MPPA. The correlation analysis showed that the BCS had a sizable
effect on milk production with a value of r = 0,68. The relationship between
BCS with milk production was expressed in the regression equation MPPA (Kg) = -
59 + 1991 BCS, means the rise of unit will increase milk production of 1991
kg/lactation.
