A new study from the University of Calgary shows a promising way to fight Johne’s disease in dairy cattle. This disease, caused by a specific harmful bacteria, has been a big problem for dairy farms worldwide. The research introduces the use of phage therapy, where unique viruses are used to target and destroy these bacteria, protecting young calves from infection. If successful, this method could improve herd health and save farmers money by reducing the disease’s impact. The study found that phage therapy provides strong protection for calves, cutting down the spread of the bacteria. This could lower Johne’s disease rates in herds and help farmers avoid losing about $16,500 yearly for a herd of 1,000 cows. This approach might also help reduce the use of antibiotics in agriculture, offering a new direction for farm management.
