Influences of calving year, calving season and parity on the lactation curve of Korean cattle



Influences of calving year, calving season and parity on the lactation curve of Korean cattle



Journal of Animal Science and Technology 44(6): 661-668



This study was conducted to investigate the effect of environmental factors on milk yield and estimate the lactation curve of Korean cattle. Data on milk yields were collected from 118 cows from the National Livestock Research Institute in Daekwanryoung, Kangwon-do from 1997-2000. Average daily milk yields for 1st, 2nd, 3rd and 4th month after calving were 3.74, 3.64, 3.26 and 2.99 kg. The average daily milk yield for the four months was 3.52 kg.
