It's a well-known fact that lame cattle can experience reduced milk production and increased disease incidence, but the effects of lameness can also negatively affect fertility and reproduction. Jeff DeFrain, research nutritionist at Zinpro, says the link between lameness and fertility is what he considers to be a “hidden transaction” in the profitability equation. “Checks are either written or cashed when it comes to milk income, hoof trimming and culling,” he says. “However, the true cost of poor fertility, especially as it relates to lameness, becomes difficult to assess in most cases.” When compared to healthy, non-lame herd mates, research indicates that lame cows have decreased conception rates, more services per conception, increased presence of ovarian cysts and an overall decrease in pregnancy rate.
