The conversation focuses on four concerns associated with sulfate trace minerals in the dairy ration:
- Essential nutrient instability: Sulfates’ reactive nature can be detrimental to Vitamins E, D and A, while also tying up expensive minerals like phytate phosphorous
- Impact on rumen function – while sulfates’ effects when used in footbaths are helpful, their oxidative properties can cause more harm than good inside the animal. Data shows about 3 points of NDFd is lost when zinc and coper sulfate trace minerals are included in the ration.
- In economic terms, the cost of using sulfate trace minerals in the ration comes out to about 30 euro cents per cow per day.
- Higher levels of minerals excreted into the environment represent another concern with sulfates
Research suggests replacing sulfates with organic trace minerals; a blend of organic and hydroxy trace chloride; or hydroxy trace chloride minerals is a sound nutrition resolution to make in 2020.
