The barn has a bad smell, making it difficult to clean and clean regularly
The majority of the barn is called “Tsunagi barn”, which is a type of barn that is tied up and kept in a stable. There are other free-range livestock farms, such as Free Stall Barn and Looseburn Barn, but in general, you can think of this type of barn as we see it.
Let’s track the day in a typical leashed cage. At the beginning of the day, you must clean the hot and cold water tank and the breeding tank and check the health of the cow. Before milking, the barn is cleaned, and after milking, all tools used are cleaned, washed and sterilized. In the meantime, we also dispose of the compost. In this way, most of the day is spent cleaning. Even so, according to documents from the Kaori Odor and Environment Association, which studies measures to prevent odors in business locations, the number of odor complaints in the livestock industry is close to 300. shifts per year.
Throughout the livestock industry, the “three main sources of odors” are odors arising from barns, odors arising from manure handling and odors arising from animal feed. Why does the barn stench not go away even though it takes time and effort to clean up?
From “eliminating” odors to “ingenuity to stop generation”
It seems that the reason that barn odors do not disappear so easily is that the coping measures cannot catch up after the smell is generated.
The association recommends “limiting odor generation as much as possible” based on the fact that “it costs a lot of money to treat odors with high concentrations and large volumes of air with just one deodorizer”. In other words, instead of how to deal with odors, it has turned to efforts to prevent odors coming out in the first place.
In the barn, it is essential to clean the manure at an early stage, but by treating the manure and urine separately rather than together, it is possible to prevent ammonia in the urine from reacting with the microorganisms in the stool. and increase its appearance. I will. Even when compost is composted from there, odor generation can be prevented by rapidly drying it.
Manure technology is also being noticed shortly back into compost and carpet. The introduction of a large machine to ferment the manure helped to prevent odor generation and to perform cleaning work.
Is there a sweet scent? The warehouse is growing
A variety of buffering padding types are also in use. Previously, people used rice husks and dry scrap, but today people use rice husks, coffee pods, cocoa pods, straw, used paper, … with high absorbent capacity and airy capacity. gas. Now in use.
Have you recently visited a farm for a tour or experience and ask yourself, “Oh? It smells sweet even though it’s a warehouse.” By spraying chocolate fragrances on barn doors and compost houses, or by placing cocoa pods, coffee pods and pea powder ordered from coffee and chocolate factories cola in the nest, the barn will be filled with the aroma of coffee. It could be because it is.
In addition, dairy farmers are working on a variety of countermeasures to cope with odors, such as structural design to improve ventilation and ventilation. In the future, it seems likely that the number of facilities that are comfortable and that are not noticeable will increase.
