It has been determined that dry cow dung contains 10%-20% crude protein, 1%-3% crude fat, 20%-30% nitrogen-free extract, and 15%-30% crude fiber, which is a good source of nutrition. One thing that can be used as long as it is used can also turn waste into treasure. This is mainly because cattle are ruminants. The feed that is eaten is decomposed by fermentation of rumen microbes in cattle. Some of the nutrients are absorbed and used, and the other part of nutrients can be used as a single stomach. Animal protein nitrogen, microorganisms, and rumen fluids are excreted. Therefore, it has a certain feed value. However, pigs cannot be fed with raw cow dung, and it is best to ferment the cow dung in silage. The method comprises the following steps: mixing cow dung with gluten, bran and other feeds, adding appropriate amount of gold bait feed fermenting agent into a cellar, a cylinder or a plastic bag in a compacted closed industry for fermentation. The fermented cow dung has good palatability and can replace some of the other feeds. Pigs gain more weight after eating. In the amount of cow dung, pigs and piglets are generally unsuitable to use cow dung, and the amount of fat in the finishing pig diet should be 10%-15%. There are more crude fibres in cow dung, so it is necessary to gradually increase the amount of feed and it is not advisable to add too much. Details can visit the website or consult.
A greenhouse(also called hothouse)is a building or complex in which allow for greater control over the growing environment of plants. Depending upon the technical specification of a greenhouse, key factors which may be controlled include temperature, levels of light and shade, irrigation, fertilizer application, and atmospheric humidity. Greenhouse may be used to overcome shortcomings in the growing qualities of a piece of land, such as a short growing season or poor light levels, greenhouses are often used for growing flowers, vegetables, fruits, transplants and seedlings. Greenhouses can be divided into glass greenhouses and plastic greenhouses. Plastics mostly used are polyethylene film and multiwall sheets of polycarbonate material, or PMMA acrylic glass. Commercial Glass Greenhouse are often high-tech production facilities for vegetables or flowers. The glass greenhouse are filled with equipment such as screening installations, heating, cooling and lighting, and may be automatically controlled by a computer.
