This temporary eating slump increases production cost and hampers pig performance through finishing 这种短期的采食减少会增加养殖成本，影响整个生长肥育期的生产性能。
Birth weight of the piglets is positively related with average daily gain of the piglets and the growing - finishing pigs 乳猪的出生重和以后仔猪和生长-肥育猪阶段的日增重正相关。
The growth and the feed conversion were improved by adding multienzyme in the miscellaneous meal diet for fattening pigs 在杂粕型日粮中添加杂粕溢多酶，能提高肥育猪的生长速度和饲料转化率。
Production per sow and growth rate per growing - finishing pig increased in the last decades with a huge variation between farms 近几十年来，每头母猪的生产能力和生长肥育猪的生长速度提高很多，但是不同的养殖场间差异很大。
Application of broken - line analysis to assess floor space requirements of nursery and grower - finisher pigs expressed on an allometric basis 应用残破线分析的方法根据体形变异对养殖场和生长肥育猪的地板面积的要求进行评估。
The sow has an effect on the birth and weaning weight of piglets and therefore on the weight development of the growing - finishing pigs 母猪自身差异会对乳猪的出生重和断奶重有影响，进而会影响到后期生长-肥育猪生产性能的表现。
When the content of miscellaneous meals in diet is the same and the adding amount of a yiduo multienzyme was different , the daily gain of pigs and the feed conversion were improved with the increase of adding amount of multienzyme 摘要日粮中杂粕含量相同而杂粕溢多酶添加量不同时，肥育猪日增重和饲料转化率随著杂粕溢多酶添加量的增加而提高。
