متن کاملThe relation of the post-partum breeding interval to reproductive efficiency in the dairy cow.

Cows calving every i~ months or less had higher yields per day for the interval between calves than did cows that required more than ~ months before reproducing in studies by Gaines and Palfrey (i931) and Chapman and Casida (I935).

متن کاملDiagnosis and Treatment of Post Partum Uterine Abnormalities in the Cow

Achievement of optimum herd reproductive performance (calving interval of 12 or 13 months with the first calf born at 24 months of age) requires concentrated management activities especially during the first 100 days foll...
