BCS Targets: Why Body Condition Score Matters at Calving
Body Condition Score (BCS) is a critical element in managing the health and reproduction of the dairy herd.
GrainCorp Feeds NZ general manager Daniel Calcinai claims that there is conflicting advice out there.
“While some dairy industry commentators are advocating for farmers to reduce costs by selling cows and not buying in supplementary feed, I believe this is a short-sighted approach,” says Calcinai.
“Reducing your herd size and cutting out supplementary feed may not be the best option and could affect the profitability of some farm businesses over the next few years, not just this season.
He says farmers need to take a long-term approach to their decision- making, to minimise risk and give themselves the best chance of success.
“While prioritising the use of homegrown feed, the best thing farmers can do is review inputs, including their herd’s total diet, and create a base feed plan, including costs and income. This will help them see what margins might be achievable in various scenarios.”
Tracking production in real time can help them make more informed feed and herd management decisions, he says. “Based on our calculations, in most cases, feeding the right feed at the right time will continue to pay off financially.”
He says farmers can elect to have their milk data sent to his company from their milk companies daily, which they upload into Tracker.
“We can then use that information to help them monitor outcomes of decisions made, plan, budget and evaluate different scenarios.
“We then combine real time information with other data to measure things like feed conversion efficiency, milk urea nitrogen, milk quality and composition, Fat Evaluation Indexes (FEIs) and margin. This can help farmers make better, fact-based, proactive decisions.
“It’s about maximising the utilisation of homegrown feeds and then adding the right supplement to complement the seasonal pasture conditions and the cow’s diet. Our goal is to improve rumen function and feed conversion efficiency in a cost-effective way.”
Making sure cows are efficiently turning feed into milk will be crucial as farmers start exploring ways to reduce their on-farm emissions.
Dairy companies are rallying to support farmers to reduce on farm emissions and protect the industry’s global competitive advantage. Fonterra recently released information to help its suppliers reduce emissions and their farm’s carbon footprint by recommending specific actions they can take.
Three key areas in which Fonterra encourages farmers to act are through improved animal efficiency, better nutrition and understanding the implications of supplementary feed.
“While on-farm emissions targets don’t come into effect until 2025, our team is equipped to help farmers get ready and get some runs on the board now. It’s a busy and challenging time for dairy farmers. We have a responsibility to step up and do what we can to help ease the load,” says Calcinai.
“For example, we can help measure, monitor and alter milk urea nitrogen levels excreted by improving a herd’s nutrition, optimising rumen function and feed utilisation.
“Not only can this help reduce the levels of nitrogen excreted on pasture and reduce the risk of waterway leaching, if managed and implemented correctly, but it can also improve productivity and margins. It’s all about efficiently turning feed into milk, minimising waste, and maximising milk output.”
Calcinai says farmers are being told to reduce their her size but this shouldn’t come at the expense of production.
