摘要

本文讨论了拉脱维亚奶牛场在隔间床上饲养奶牛的经验。人们发现,这个国家以这种方式饲养的牛的数量每年都在增加。如果在2010年,大约35%的奶牛被关在小隔间里,那么现在这个比例已经超过了50%。此外,高隔间和深隔间都很常见。结果表明,采用深隔间床,在牛床上填满沙子,产奶量最高,牛奶质量也较高(以SCC为基础)。如果使用高隔间床或深隔间床加上其他床褥,奶牛的产奶量平均降低15%。另一方面,高隔间床的SCC数量增加了50%,深隔间床的SCC数量增加了40%。然而,这个数字在很大程度上取决于清洗隔间的频率和重新填充床上用品的频率。

Studies of cubicle bed design in latvian dairy farms
The article discusses the experience of Latvian dairy farms in keeping cows in cubicle beds. It has been found that the number of cows kept in this way in the country is increasing every year. If in 2010 about 35% of the total number of dairy cows were kept in the cubicles, now it exceeds 50%. In addition, both high and deep cubicles are common. It was found that the highest milk yields and high milk quality (based on SCC) were obtained using deep cubicle beds in which the cows’ beds were filled with sand. If high cubicle beds or deep cubicle beds with other bedding are used, the milk yield of cows is on average 15% lower. The number of SCC, on the other hand, increases by 50% with high cubicle beds and increases by 40% with deep cubicle beds with other bedding. However, this figure depends to a large extent on the frequency of cleaning the cubicle and the frequency of refilling the bedding material.
