Abstract:

The test was conducted to study the effect of different culture ways on health and development of Japanese Black calves in cold area,20 healthy and newborn calves were divided into 2 groups using single factor randomized block design.Calves of control group were fed using traditional feeding method while calves of experimental group were fed using artificial feeding method.The test period was 180 d,body weight and body steep size indexes of calves were measured,and the health condition of calves were observed.The results showed that when weaned at 3 months old,body weight and average daily gain of calves in experimental group were significantly higher than that of control group (P<0.05);Body weight and average daily gain of calves with 6 months old in experimental group were significantly higher than that of control group (P<0.05);The fecal index,diarrhea rate,diarrhea frequency and death rate of experimental group were lower than that of control group,and the difference of diarrhea rate and diarrhea frequency were significant (P<0.05).And the respiratory disease incidence,incidence frequency and death rate of experimental group were lower than that of control group,the difference of the three indexes were significant (P<0.05).The results suggested that artificial feeding method could improve the Japanese Black calves survival rate,strengthen the prevention of diarrhea and respiratory disease and sufficiently play the potential to improve calf weaning weight.It not only could reduce the economic costs of farms,and also significantly improve the economic efficiency of domestic high-quality beef cattle.

Key words: Japanese Black calves; traditional feeding method; artificial feeding method; weaning body weight; survival rate; grow and development
