In HI’s February issue (pgs. 10-11) you became acquainted with the phenomenon Beef-on-Dairy: the breeding of dairy cows to beef bulls. As the result of extensive use of sexed semen in many prominent Holstein countries, this is a growing practice. In this article, we will consider a number of breeding programs which have been developed to select the best possible beef bulls to meet this end goal. And you receive an overview of the bulls from various beef breeds that are recommended by AIs for use on dairy cows. Also with Beef-on-Dairy, it is the case: do not use “just any bull”; also here, better bulls clearly lead to better results.
