A recent study by scientists at the famous Madison Dairy Research Center found that a certain amount of nitrogen is very important for lactating cows, but excessive nitrogen not only seriously pollutes the environment, but also can cause milk production under certain circumstances. decline. Dairy scientists believe that the minimum nitrogen supply in the diet is 16.5% without affecting the amount of milk. And the proportion we generally supply in dairy farming is 18-19%, which is much higher than 16.5%. These excess nitrogen can't be used by cows, but it becomes nitrogen waste, such as urine nitrogen, which is excreted by milk steaks. These nitrogens are easily converted into ammonia and evaporate into the atmosphere to form acid rain, and the large amount of these wastes tends to be more concentrated. Serious pollution of the earth's soil, vegetation and surface water is a serious environmental problem. Very high sample collection and release volumes.Greatly improved the accuracy of the inspection .
