Eighteen multiparous dairy cows were dried off approximately 4 wk prior to the expected calving time in a completely randomized design. For intermittent milk cessation treatment, cows were dried off in the following manner. Milk samples were collected from front and rear quarters at 7d to 3d prior to drying off, at drying off, 14d, 7d prior to calving, at calving, and 7d post calving. Milk yield at drying off day was recorded. Lacteal secretion samples were stored at -18Ċ and used for lactoferrin quantitation. Other samples were stored at 4Ċ for somatic cell count, total bacteria count and other milk components. The results indicated that, there were no differences in fat, protein and lactose percentages and milk pH between two drying off methods (P>0.05). However, there was a significant effect of drying off methods on lactoferrin concentration it was higher in dairy cows dried off by intermittent milk cessation, applied in 2 and 1 wk prior to calving time (P }, URL = {http://jcpp.iut.ac.ir/article-1-1071-en.html}, eprint = {http://jcpp.iut.ac.ir/article-1-1071-en.pdf}, journal = {Journal of Crop Production and Processing}, doi = {}, year = {2009} }
