Heat and its partner in crime, humidity, wreak havoc on dairies, pushing milk production and pregnancy rates down and herd health problems up. Incidences of stress on cows can occur at temperatures as low as 72˚F/22˚C when combined with higher humidity, dramatically reducing profitability on the dairy.
Looking for solutions to keep the window of breeding opportunity open a little longer and combat these issues, Semex has designed its Repromix product to help get those problem, repeat breeders back into calf, reducing days open and into their next lactation and the milking line.

This process includes the modification of proteins on the outside of the sperm cell by the cow’s reproductive tract. Without this process, sperm cannot fertilize an egg. As timing with all reproduction is key, the time needed for the capacitation process to occur varies from species to species and in our case, bull to bull.
