Batch AI crushes are now included in the Traditional Agricultural Modernisation Scheme (TAMS) II. The batch crush allows farmers to artificially inseminate (AI) a group of cows quickly and safely. In the batch crush system, cows are controlled in a similar fashion to a herringbone parlour where a group of cows stand in a row side by side. Batch crushes have become more popular on expanding dairy farms where large numbers of cows have to be inseminated daily during breeding. Traditionally cows were artificially inseminated in an ordinary cattle crush. Some farmers have found this system to be tedious because each cow has to be individually restrained.
