Impact of calving interval on milk yield and longevity of primiparous Estonian Holstein cows
Data about 4 474 high-yielding Estonian Holstein dairy cows from 14 herds was analysed for the impact of the first calving interval length (CI1) on milk yield (MY) and lactation persistency. The results show that cows with CI1 shorter than 12 months have on average 2 345 kg lower milk yield in the f...
