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.

Abstract

The objective of this research was to assess test interval method for estimation of milk yield of Friesian Holstein Breed in tropical condition for alternative selection in herd. Purposive sampling method was used in this research. Milk yield data were collected base on daily yield from 3 heads lactating cows. Estimated milk yield from test interval method and actual milk yield were analyzed using statistical correlation analysis. The results showed that estimated milk yield significantly correlated (P<0.01) to actual milk yield (r = 0.991). The estimation of milk yield of individual cows was lower or higher than that of their actual milk yield at 305 days never more than that of 0.29 to 0.79 %. It was concluded that test interval methodcould be used accurately to estimate milk yield and in addition could be used for selection of Friesian Holstein Breed in wet tropic area
