| Abstract: | PAC complex feed additive was used to feed Holstein cows. Results demonstrated milk yield and milk fat content of Holstein cows could be increased 7.62% and 10% with addition 0.4% of PAC complex feed additive. This additive could cure mastitis and reduce somatic cell count significantly |
