Dairy farm water requirements - some basics

Providing enough water to stock is essential for high milk production. Clean water is also required in large quantities for cooling milk and washing the milking plant.

Water Requirements - A lack of trough water can cause milk production to be restricted in the summer. Thirsty cows will also lose condition, because they lose their appetite. Peak water flow rates needed on a dairy farm should be worked out on a per cow basis.

Dairy shed 70 litres/cow per day Troughs 70 litres/cow per day, available in a 5 hour period = 14 litres/cow/hour


Why delivery of minerals to livestock via water achieves optimum results

Why delivery of minerals to livestock via water achieves optimum results

One of the observable differences between New Zealand and Australian pasture based production systems is the adoption of inline water mineral delivery systems. These are now very common in New Zealand situations, for the introduction of different medications into stock water supply.

Simple things you can do to avoid mould spoilage of wrapped haylage and silage.

Plastic wrapped square or round baled silage or haylage will always present a greater risk to the farmer from spoilage than will pit silage. This is simply due to the greater potential surface area a wrapped bale presents to air. By contrast, a covered silage pit has only the top surface exposed.

Ryegrass staggers is a disease of grazing animals that affects nerves and muscles and can result in spasms, loss of muscle control and paralysis.

Coccidiosis - treatment and prevention management in grazing stock

Coccidiosis is now quite common and is easily recognised as a scour where the muck is spread either side of the pin bones and the calf is continually waving its tail from one side to the other to keep it off the sore anal area.
Coccidiosis scours will linger far longer than other scour types and won't be cured with worm drenches. Even full grown cows can be found displaying the symptoms.

Salt as a Fertilize

Salt as a Fertilizer - Useful or Useless?

Note : This article was written many years ago,  when I was a dairy farm consultant in New Zealand.  While Australia is not New Zealand, and many soils in Australia are sodic (although not very many in dairying) , the messages this article contains are just as pertinent to Australian soils as they are to New Zealand’s.
