New Technology Touted To Fight Dairy Disease

“We are one ‘60 Minutes’ report away from rules against either leukosis or Johne’s.” – MARK VARNER A recently introduced technology to predetermine the sex of dairy cattle could also be the key to eliminating infectious diseases in dairy herds. Sexed semen, in which sperm is sorted for gender, can help milk producers develop herds

Gender Sexing Coming To Hog Barns

Gender sexing will soon be commercially available through semen processing, Phil Burke of Minitube Canada told the annual meeting of Ontario Swine Improvement Inc. here recently. He said his company has achieved good results with an additive, then processing. That approach has shifted the gender balance from 51 per cent females, 49 per cent males
