Biotin and its role in improving hoof health.

Biotin (Vitamin H or B7) is an essential water-soluble vitamin. It is naturally present in some feeds and can be synthesised by rumen microbes.  Usually, ruminal biotin synthesis supplies sufficient biotin for biological functions, however, diets containing high quantities of grain may reduce the natural synthesis of Biotin by the rumen. Biotin for hoof hardness. […]

Effective facial eczema prevention

Facial eczema is caused by a toxin, sporidesmin, which cows eat when grazing pastures high in fungal spores. Trials conducted at AgResearch by Dr Neale Towers calculated the effect of low doses of sporidesmin on milk yield. Over a three week period, production across the herd had dropped by as much as 25%. For a […]

Nutrition support for cows during heat stress conditions

Heat stress can significantly impact cow health and production. It can lead to reduced feed intake, rumination, rumen function, milk yield and milk fat and protein levels, and increased respiration rate and risk of acidosis. While many of us are aware of practical solutions for heat stress (such as providing shade, increasing access to water […]

The Scientists Corner: Rumen epithelium inflammation in transition

The transition around calving is a critical time for the dairy cow with major dietary, metabolic, and physiological changes. In particular, the transition from a high-fiber to a high carbohydrate diet (or vice versa in the case of cows wintered on fodder beet) represents important challenges for rumen microbiota and, thus, rumen health with a [...]

Nutritional Impacts of the Wet Weather

As we navigate another period of wet weather, there are some key points which we must keep in mind as we head into the new season. When grass gets covered in soil and dirt it leaves deposits of Ash and specific metals which can cause problems. Any pastures that have flooded or had lying water, [...]

Transition Cow Nutrition

Various factors contribute to the profitability of any New Zealand dairy herd, production, longevity, fertility and cow health could all be considered key factors. Managing a successful transition period is a key element to achieving all these factors. Poor feeding and management during the transition period can result in a host of problems around calving [...]

Transition Cow Feeding and Management

A significant proportion of any herd’s health and welfare costs can come from the 3 weeks pre-calving to the 3 weeks post-calving. This is the period where the cow lays down the building blocks for the coming lactation, so minimising metabolic disease and implementing a system to reduce negative energy balance and maximise post-calving dry [...]

Managing Heat Stress

Heat stress occurs when cows are unable to control their body temperature at high temperatures, which leads to reduced feed intake, rumination, rumen function, milk yield and milk fat and protein levels, and increased respiration rate and risk of acidosis. The higher the relative humidity (RH) the lower the temperature at which heat stress occurs, [...]

Holding Yields at Peak

There is an opportunity with increasing dairy prices to maximise returns by maintaining milk yields as high as economically possible after peak, with diets based around home grown feeds (pasture, other forages, crops). Maintaining intakes of feeds with high Metabolisable Energy (ME) levels are key to sustaining milk yields and body condition, which may be [...]
