Joint research programme focuses on rumen development
AgResearch and Fiber Fresh feeds have recently released their first trial results on rumen development in calves, as part of an ongoing research collaboration.

Fiber Fresh is a world-leading, progressive, family-owned calf and equine nutrition company based in Reporoa, with an active scientific R&D division. The recent AgResearch trial, which began in 2013, indicates that high nutritional fibres help promote rumen development in calves. The development of the rumen is important for the young calf to enable transition from milk to pasture. The rumen development study showed fibre-reared calves had 18% heavier rumens, better papillae development in some parts of the rumen and greater vascularity compared to calves fed on conventional meal-based systems. Calves reared on the fibre diet also exhibited better rumen absorption capacity at weaning and were slightly more efficient in feed usage (2.4% apparent feed efficiency). Those calves are also involved in a lifetime study to evaluate the effects of nutrition during rearing on meat quality and production. A number of other trials are also planned as part of the ongoing research programme, including a lifetime trial of heifers to establish the impact of early intervention on future milk production. Fiber Fresh national business manager Shona Goss says the relationship with AgResearch came about throughout wanting to provide robust, independent information to farmers about Fiber Fresh products. “We had farmers claiming results they’d seen by using Fiber Fresh products and we had conducted a number of in-house trials. But ultimately we need robust, independent scientific evidence. “We believe there is a better way to rear healthy, productive animals and we […]
