摘要: The incidence of anaemia (defined as a haemoglobin concentration 9.8 g/100 ml blood or less), in 7,075 dairy cows was 10.6%. giving 0 to 7 kg, 8 16 and greater than kg milk on the day sampling 4.4%, 9.8% 15.9% respectively, higher between December March (17.7%), regardless yield, at other times. Cows over 9 years old highest yields 2-3 lowest were more prone this time others similar yields.
