Whole farm management. Reducing nutrient losses to manure requires attention to nutrient flows through the system and improving the efficiency of nutrient conservation by the herd, crops and manure systems.Reducing nutrient excretion by dairy cows. If cows excrete less nitrogen and phosphorus, nutrient losses to the environment are reduced, and compliance with nutrient management plans is made easier. This page shows how.
Using Milk Urea Nitrogen (MUN) to evaluate diets. This tool can identify when too much or too little protein is consumed by dairy cattle. Using MUN can save farmers money and reduce nutrient losses to the environment.
Effect of animal grouping on nutrient flows on the farm. The way cows are grouped affects the nutrient consumption and excretion in herds.
Comparison of different diet formulation models. The NRC recommendations were compared to the Cornell Net Carbohydrate System for balancing dairy cow diets.
Balancing the diets of lactating dairy cows for amino acids.
Impact of crop selection on nutrient flows. Are certain crops advantageous for capturing nutrients from soil and delivering them to dairy cattle.
Impact of using three times daily milking, bst or increased photoperiod on nutrient losses to the environment.
Phosphorus management. How much phosphorus do you need to feed?
