Nitrate poisoning in cows happens when they eat feed with high nitrate levels, often in late autumn or winter.

Grass silage is pickled pasture, preserved through the conversion of its sugars into lactic acid by bacteria. This process extends the shelf life of the pasture beyond what it would have if exposed to open air.

White clover is a top-quality feed used widely in New Zealand's dairy pastures. Different types have varying purposes in dairy farming. Italian and Annual ryegrass, and Red clover perform well in summer dry areas, complementing white clover in mixes.

Managing high-quality pasture during feed surplus periods is a crucial skill in pasture management. This page explains that pasture surplus often develops in spring, which if unmanaged, can lead to low-quality pasture affecting milk production.

Calculating Metabolisable Energy (ME) needs is important for dairy cows. You adjust for feed quality by adding or subtracting 4% per MJ ME/kg DM from the standard 11.0 MJ ME/kg DM.

Kale is a winter feed crop with a deep root system, making it drought-resistant. It's tolerant to many pests and is often grown after swedes due to its resistance to club root and dry rot.

Late summer strategies in dairy farming involve continuous monitoring of feed demand and body condition score (BCS). This page discusses how managing pasture effectively, considering factors like over-grazing and dry periods, is crucial.

Heifer grazing involves estimating your farm's ability to support the growth of dairy heifers to meet their target weights. It's important to evaluate the number of heifers your land can sustain based on the amount and quality of pasture.

Dry matter is a crucial dietary requirement for dry cows. This page outlines the energy a cow needs, considering its weight gain or loss. The feed requirement considers the cow's maintenance, pregnancy, and weight gain.

Comparative Stocking Rate (CSR) is a tool to measure the balance between feed demand and supply on a farm. It is determined by calculating the amount of livestock weight per hectare versus the annual feed available.

Cocksfoot is a resilient pasture grass, ideal for dry conditions and resistant to many pests. Though its feed value is typically lower than ryegrass, it supports summer growth in dairy pasture mixes, especially in drought-prone areas.

Choosing the right supplement for your dairy farm requires careful consideration of factors such as energy content, cost, storage, wastage, and feeding logistics.

Peter and Joc Kinney are dairy farming near Culverden. The dairy farm has an effective milking platform area of 310 ha. At the start of the FRNL programme this was 95% irrigated, at a stocking rate of 3.8 cows/ha.

Welcome to DairyNZ's Lye Farm. Home to world class udder health and intensive indoor nutrition research.

The Southern Dairy Hub was established in response to Southland and Otago farmers wanting dairy challenges in the region to be addressed through local research and demonstration.
