The effect of linseed on reproduction performance of fresh dairy Holstein cows

In order to investigate the effect of linseed on reproduction performance of fresh dairy Holstein cows, 99 primiparous and 100 multiparous cows were used under the control and linseed treatments till 28th day after parturition, and after that the same diet were used. For statistical analysis, the LOGESTIC procedure of SAS statistical software were used. Results showed that, reproductive performance of dairy cows such as mean number of artificial insemination, conception rate and endometritis were not affected by linseed treatment. The incidence of cystic ovary was similar for multiparous and primiparous cows fed linseed. However, it was higher for multiparous cows, when fed the control treatment. Do to the lower incidence of cystic ovary in multiparous cows, it is suggested to feed dairy cows with linseed especially in those farms that have management problems.
