摘要:

目前中国母猪年生产力(PSY)水平与同期发达国家相比偏低,主要表现为仔猪断奶前死亡率高,对养猪业造成较大损失。为了解中国仔猪在繁育环节的经济损失情况,基于1980~2016年中国PSY数据,总结中国近37年PSY的波动趋势及原因,对仔猪繁育环节死亡仔猪带来的乳汁及教槽料损失进行估算。估算结果为:中国仔猪繁育环节乳汁的损失系数为3.47%~3.50%,2015年损失乳汁56.17万~77.71万t;教槽料损失系数为1.63%,2015年损失教槽料4.80万t。中国仔猪繁育环节的损失系数远高于发达国家,其中乳汁与教槽料损失系数均是PSY最高的丹麦的1.59倍,均是损失系数最低的爱尔兰的2倍多。仔猪繁育环节的损失系数与仔猪断奶前死亡率有关,教槽料的损失系数由于不同生猪养殖场饲养方式不同存在较大差异,所以,要提高养殖场管理水平,尤其要加强断奶前仔猪的保育,减少死亡率。

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
