There is a mantra that the 3-week transition period each side of calving, critically important to the productivity and health of cows and their calves, is as easy to ignore as a background radio. I think it is worth re-stating and action taken where improvements can be made. Calcium is not just critical for bones […]

Magnesium (Mg) is an important macromineral that has many functions within the body including nerve and muscle function, immune system function and bone health. As magnesium relaxes nerve impulses after transmission, a more minor deficiency can manifest itself as excitability and nervousness in cows, whereas excessive intakes can cause sedation, with cows becoming more lethargic […]

It’s good to see that another internationally appreciated animal feed – corn gluten meal – has entered the New Zealand market and is now starting to trickle into regional ports. Importation has no doubt been encouraged by the Fat Evaluation Index (FEI) penalties that have been indicated by Fonterra to come into effect next season, […]

With autumn upon us, most dairy farmers will be starting to make decisions about when to start drying off, with body condition at front of mind. Thanks to considerable research both within New Zealand and internationally, it is clear that body condition score at calving plays a significant role in ensuring a productive lactation, including […]

Fonterra’s Fat Evaluation Index (FEI) may encourage farmers away from straight palm kernel extract (PKE) to other straights, layered loads or blends. The huge popularity of PKE in New Zealand suggests that if levels are reduced, either something will have to fill the gap or national milk production levels will fall. Lower input/lower output systems […]

The element sodium (Na) is essential for all animals. It functions as a major extracellular cation and is essential for maintaining osmotic pressure in the body as well as water regulation. It is essential for transporting nutrients around the body and removing waste from cells. It is also involved in nerve impulse transmission and muscle […]

Falling pasture quality over the coming months can dramatically affect the performance of milking animals and young stock, but countermeasures are available. Spring calving cows should be “in their groove” by November – they will have peaked in production and now be gradually easing back while regaining condition as best they can. Carefully reared calves […]

In terms of reproductive performance, if conservative by nature or restrained by budgets it might be worth starting with the little things and working up the food chain rather than concluding the big cost items are beyond reach and do nothing. Essential trace minerals are reactive elements that are required in tiny amounts that get […]
