which have clearly identified key parameters influencing cow longevity.
Meanwhile, Nick Bell from the Royal Vet College will also be chairing an interactive foot trimming discussion panel with a group of foot-trimmers. The “Dimbleby Question
Time” style session will discuss the need to adjust foot trimming regime to reflect farm environment and individual cow requirements and address the topic of over trimming. Nick says over trimming can be a particular issue on cows with curled toes, where it is difficult to judge toe length. He explains: “For many farmers, it may be that a small number of cows need a slightly different approach. Rather than just trimming to 7.5cm as standard, it’s important to trim
to the optimal dimensions for an individual cow’s anatomy. We’ll explore how we assess optimal.” Vet and independent
consultant, John Cook will also be highlighting how farmers can benefit from using data and computer software to understand and improve upon weaknesses in their fertility management routine. “At the current milk price, production needs to be efficient and milk production ultimately comes from fertility. By using computer software you can track whether key groups of at risk cows are hitting certain fertility goals,” he says. Although pregnancy rate is vitally important, John believes
one of the most important indicators to look at is the proportion of cows inseminated by 80 days in milk.
He says: “80% of the variation in reproductive performance is explained by the number of days in milk that a cow is inseminated. By delaying getting her back in calf, you are extending the period it takes her to get back to peak production, which ultimately impacts on economics. “To hit targets you’ve got to use fertility monitoring tools, together with an appropriate level of hormonal intervention. At the current milk price, you can’t afford not to,” he stresses.
