Reasonable choice of raw materials Feed ingredients are the basis of processed feeds. The selection of raw materials must first ensure that 90% of the raw materials come from certified green food products and their by-products, and others can be products that meet the green food standards; secondly, pay attention to the high purchasing and digestibility. Variation of small raw materials. It has been determined that the selection of feeds with high digestibility can at least reduce the excretion of 5% nitrogen in the excreta. Again, it is necessary to pay attention to the selection of feeds with low toxic and harmful ingredients and high safety so as to reduce the environmental pollution after the toxic and harmful components are accumulated and discharged in livestock and poultry. Feed precision processing The precision of feed processing has a great influence on the digestion and absorption of livestock and poultry. Different livestock and poultry require different feed processing requirements. Li Defa (1994) reported that pig feed pellets were between 700 μm and 800 μm with the highest feed conversion rate. The use of puffing and granulation processing techniques can destroy and inhibit anti-nutritional factors, toxic and harmful substances and microorganisms in feed, improve feed hygiene, increase the digestibility of nutrients, and reduce the dry matter discharged from the manure by one-third. Formulated amino acid balance diet The amino acid balanced diet refers to the diet formulated according to the "ideal protein model." That is, diets with amino acid levels that are compatible with animal amino acid levels. According to reports, on the basis of meeting the needs of effective amino acids, the protein level of the diet can be appropriately reduced. According to research data, the excrement of livestock and poultry, the excretion of contaminants from the housing, waste, and harmful gases are all related to the components of the diet of livestock and poultry. When the protein content in the pig diet was reduced by 1%, the nitrogen output was reduced by 8.4%. If the crude protein content in the diet is reduced from 18% to 15%, nitrogen emissions can be reduced by 25%. If the protein in the diet of the chicken is reduced by 2%, the fecal nitrogen output can be reduced by 20%. Fecal contamination odor is mainly caused by the corruption of protein, which is caused by incomplete absorption of nutrients in the diet. If the dietary protein digestibility is increased or the protein supply of the diet is reduced, the generation of malodorous substances will be greatly reduced. This can not only save protein resources, but also is an important measure to fundamentally reduce the nitrogen pollution of livestock and poultry manure.
Bee Pollen comes from
nature, is the bee from the flowers (nectar plants and pollen plants)
flowers collected in the pollen grains, and joined the special glandular
secretions (nectar and saliva) mixed into an irregular Flat round shape. Bee
pollen has a unique natural health care and medical and cosmetic value,
is more and more people know, is a high-protein low-fat nutritional
health food, known as "all-round nutrition food" "concentrated natural
medicine library" "Oral cosmetics" and so on, is the treasure of human natural food.
We provide rape pollen, tea pollen, sunflower pollen and mixed pollen, they are all collected from our professional green beefarm base.
