A new method of influence pregnancy turned into commercially ready when you look at the 2004. Called the BioPRYN® try, it utilizes a research process to check on end- otherwise jugular-bled animals getting maternity (Figure 18). It’s basically an excellent “yes/no” make sure is highly right: more than 99 % for the pregnant cows and you may in the 95 per cent on open cattle.

That have cattle which might be addressed because of the pasture or herd (elizabeth.grams., chicken cattle), the first you to comparison might possibly be done might possibly be 3 months following the end of calving year. Such as for instance, a herd which have a ninety-time calving 12 months might have a great ninety-go out breeding seasons following that.
