I try to put a 0 myostatin on my shapier cows and a myostatin 1 on my plainer cows. I use the saler on my heifers so I can weed out any problem ones before they enter the pedigree herd but like everything the key is too not get them too fat and the right sire selection.How do you find the ones with the muscle gene calve? Due to expansion we’ll be running more heifers over the next couple of years (70 this year, looking at 90 next year) so easy calving is a massive thing for us
