Cow Health

Dairy herd health management benefits dairy farmers, the environment, dairy cows and citizens. It is an important part of modern dairy farm veterinary care. Dairy herd health management is assessing, monitoring and improving the health of dairy cows at a population level. Good herd health management takes a holistic approach and is ongoing and cyclical. All members of the dairy farm team and their advisors are involved, decisions are informed by data generated by the herd. These data may come from numerous sources. The data are processed and analysed to monitor cow health, target investigations and evaluate progress. To make lasting change on farms, advisors must communicate appropriately with farm managers to understand behaviour and motivate change. This chapter reviews these aspects of dairy herd health management, giving practical suggestions on how to get started, how to incorporate herd health management into business models and how to maintain momentum.

Grazing Sheep

The benefits of mixed grazing sheep and cattle have been reviewed by Nolan and Connolly (1977). Sheep performance was improved in practically all comparisons and cattle perfomance in the majority of reports. As dairy producers manage their milk quota through various efficiency options, surplus land may become available for alternative use. Based on results from other sheep/dry stock studies the introduction of sheep onto the dairy farm, to utilise surplus/waste grass throughout the year, should lead to increased pasture utilisation and improved overall farm efficiency. The sheep enterprise may be established as a distinct unit and strategically used to exploit feed surpluses on the dairy unit throughtout the year. Alternatively, the full integration of a sheep enterprise with the dairy cows to exploit the benefits of mixed species grazing, may be considered. This latter approach is being evaluated and this report covers the first year of an on-going study.

Beef Breed

Production of beef-cross-dairy calves from dairy cows increases the value of non-replacement calves born to the dairy herd. The use of beef-breed sires may impact on calf birth weight, gestation length and pre-weaning growth rate of calves, which in turn influences the profitability of the dairy farm. The aim of this case study was to compare the birth weight, gestation length, and pre-weaning growth of progeny born to mixed-aged dairy cows on a single farm which were artificially bred to a selection of Angus and Hereford bulls, typical of those used over dairy herds in New Zealand. The birth weight, gestation length and pre-weaning growth of 980 calves sired by 65 sires were compared. Mean progeny birth weight (range 33.3–41.4 kg), gestation length (range 276.1–288.6 days), age at weaning (range 70.3–88.3 days) and pre-weaning ADG (range 0.63–0.76 kg/d) differed among sires (p < 0.001). There was a negative genetic correlation (−0.31) and positive phenotypic correlation (0.36) between gestation length and birth weight. Age at weaning was negatively correlated with birth weight (genetic: −0.56, phenotypic: −0.57). Bulls used in this study, and other bulls with similar genetic merit for birth weight and gestation length would be suitable for mating mixed-aged dairy cows in New Zealand.
