| Summary: | The aim of the research was to estimate the heritability of calving interval, service per conception and post partum mating of Friesian Holstein at UPTD BPT-SP and HMT Cikole Lembang, West Java. The data used were calving interval, service per conception and post partum mating from 2007 to 2012. They were collected for analysis the heritability estimation. The data were discriptively analysed for average value and devition standard. The heritability was estimated by paternal halfsib correlation method and parent-offspring regression method. The results showed that the average of calving interval was 422,85±58,49 days, service per conception 1,61±0,74 times and post partum mating 222,54±122,61 days. The estimation of heritability for calving interval, service per conception and post partum mating using paternal half sib correlation method were 0,60±0,54
