In Nanshan, annu- al average temperature was 11.2 ℃; average temperature in the hottest month July was 18.4 ℃, and extremely maximum temperature was 26.8 0℃; average tempera- ture in the coldest month January was 2.2 ℃, and extremely minimum temperature in February was -16.0 ℃. Holstein is resistant to low temperature but not resistant to high temperature. The suitable temperature for Holstein ranges from 11 to 16 ℃, so the climatic environment in Nanshan is suitable for the breeding of Holstein. An- nual average milk yield of each Holstein was up to 6 900 kg, reaching the ad- vanced level of annual average milk yield of each Holstein in China. The milk yield of cows was the highest in June and the lowest in October.展开更多
