NZ’s low-carbon beef production to accelerate following new study
New Zealand’s low-carbon beef production is set to accelerate following the release of a new study that found younger dairy cattle produce almost half the greenhouse gas emissions of older steers. The move could help address a significant ethical and environmental concern for the New Zealand dairy sector which sees nearly two million, four-day-old bobby calves culled annually – a practice facing a potential ban by 2030 due to animal welfare concerns. The new AgResearch report found that dairy-derived beef raised to 10-18 months has a carbon footprint 29-48% lower than the average for mixed beef cattle in New Zealand. The researchers found that in dairy production, the total greenhouse gas emissions are allocated between milk and live weight sold for meat. This means that only a portion of the emissions are attributed to the beef, while the rest are allocated to the milk. In contrast, beef systems only produce live weight, so all the emissions are allocated to the beef. Daniel Carson (Ngāi Tahu), founder of Māori-owned agribusiness Mīti, which commissioned the research, says their mission is to transform young dairy calves, usually slaughtered at four days old, into a sustainable and profitable food source. He says by extending the lifespan of these calves by up to a year they are able to create a new market for a viable low-emission protein source while adding value to the dairy and beef industries. Carson says it is hoped the research will support the creation of a new low-carbon, young beef category called Mataora, specifically designed for manufacturing into added value products, and lead to more efficient utilisation of New Zealand’s meat processing infrastructure as well as a low-carbon leather for the high-end fashion sector. “At the moment young bobby calves are considered surplus to requirements and the current system treats […]
