Abstract

Abstract:

At present,the level of pigs weaned per sow per year (PSY) in China was relatively low compared with the developed countries in the same period,which mainly showed the high mortality rate of piglets before weaning,and causing high losses for pig industry.In order to understand the economic losses of piglets in the breeding sector,based on the national PSY data from 1980 to 2016,the authors summarized the trend and reason of PSY fluctuation in recent 37 years.Based on this,the estimation of the milk and creep feed loss in piglets was made.The estimated results showed that,the loss coefficients of milk in China were 3.47% to 3.50%,and 561 700 to 777 100 t of milk was lost in 2015.The loss coefficient of creep feed was 1.63%,and the loss of creep feed was 48 000 t in 2015.The loss coefficient during piglet breeding in China was far higher than that of the developed countries,1.59 times that of Denmark with the highest PSY,more than 2 times that of Irish with the lowest loss coefficient.The loss coefficient of piglet breeding was related to the mortality of piglets before weaning,and there was a great difference in the loss coefficient of feed due to the different feeding ways of different pig farms.Therefore,it was necessary to improve the management level of the farm,especially to strengthen the conservation of the piglets before weaning,and reduce the mortality.

Key words: pigs weaned per sow per year (PSY); loss coefficient; piglet
