| 1. | The breeding herds annually produce and sell a crop of calves . 繁殖牛场每年生产和售出大批犊牛。 |
| 2. | The initial focus of this project was on the development of nucleus breeding herds at the three locations ; hangzhou , shanghai and xian 最初的项目活动侧重于杭州上海和西安三个项目点加拿大核心牛群的开发。 |
| 3. | At the end of 2001 , nucleus breeding herds had grown to 448 milking age holsteins of pure canada breeding with average milk production per 305 - day lactation of 8 , 366 kgs 到2001年年底,纯加系的核心牛群达到了448头成母牛,其305天产奶量平均达到了8336公斤。 |
| 4. | The initial focus of the project was to set up three nucleus swine breeding herds , which included the jinhua pig breeding farm zhejiang , the neijiang pig breeding farm sichuan and the yutian pig breeding farm hebei 项目最初的重点是建立三个核心种猪场,包括金华种猪场浙江内江种猪场四川和玉田种猪场河北。 |
| 5. | Swine influenza ( si ) is a contagious respiratory disease or syndrome , characterized by severe respiratory disease in young pigs with almost 100 % morbidity , abortions in breeding herds and a few deaths of adult pigs 猪流感( si )是由a型流感病毒引起的猪的呼吸道疾病或疾病综合征,临床以仔猪的严重呼吸道疾病、妊娠母猪的流产和部分成年猪的死亡为主要特征。 |
| 6. | Feeding in this manner allows animals with superior growth rates to be identified and selected for use in the breeding herd and also ensures that these animals not in a deficit position in terms of meeting their genetically defined target body composition as they approach maturity 按照这种模式饲喂猪,生长速度的优越性已经得到了确定,可以选择优秀个体作为种猪群,同样也确保在它们达到成熟时,不缺乏按照基因型定义的目标体组成。 |
