To prepare piglet feed, the digestive physiology of the piglet itself must be considered first. Piglet growth rate, material metabolism, nutrient utilization ability, but the digestive system development is not yet perfect, digestive organs are not developed, small volume, imperfect function, insufficient secretion of digestive enzymes, low digestibility of feed, feed The antigenic material has a certain allergic reaction, lack of gastric acid secretion, low killing ability to pathogenic bacteria, and piglets prone to diarrhea, so the preparation requirements for piglets are higher. Raw materials should meet the digestive physiology of piglets.
According to the "ideal protein" theory, the amount of protein required by piglets is essentially the amount of amino acids needed. Studies have shown that piglets are not sensitive to low protein diets, and the key is to ensure the balance of various amino acids in the diet. Therefore, by adding some amino acids that are lacking in the diet, the balance of amino acids can be achieved in the case of low dietary protein levels (usually 18%), and good feeding efficiency can still be achieved. The first, second, third, and fourth limiting amino acids in the diet of piglets are lysine, threonine, methionine, and tryptophan, respectively. Reducing protein feeds has the benefits of reducing diarrhoea and diarrhoea in piglets, reducing nitrogen emissions from pig farms, and reducing feed costs.
Piglet protein is rich in raw materials, such as fish meal, plasma protein powder, soy protein, puffed soybean meal and so on. More common is puffed soybean meal.
Extruded soybean meal or extruded soybean vegetable protein feed usually contains a variety of anti-nutritional factors, such as the antigen components of soy protein (glycinin and globulin). These two proteins are the main causes of piglet intestinal damage, leading to post-weaning diarrhea in piglets. Limit the amount of soybean meal, not more than 20% is appropriate. Partially reduce the antigen content in the protein by processing the soybean meal, such as soaking the soybean meal or soybeans with 60%-70% hot ethanol. After fermented enzymatic hydrolysis of soybean meal, effective reduction of anti-nutritional factors in soybean protein, especially the production of a large number of small-molecule polypeptides by fermentation enzymatic hydrolysis, facilitates the digestion and absorption of dietary proteins and presents a good effect of reducing diarrhea in weaned piglets. Piglet weaning stress can lead to intestinal damage, digestive dysfunction, and decreased digestive enzyme activity, resulting in poor digestion and absorption of the protein, followed by occurrence of spoilage of the large intestine, resulting in toxic effects of amines and ammonia on the intestinal mucosa. Diarrhea worsened.
Small peptides, especially 2-3 peptides, can be fully and effectively absorbed by piglets, reducing the production of ammonia and toxic amines at the back of the large intestine. At the same time can maintain the normal function of the digestive tract and reduce the rate of diarrhea. Small peptides can also promote the proliferation of beneficial microbial flora, improve the synthesis of bacterial proteins, and increase disease resistance. In addition, certain active small peptides can promote the development of the small intestine of young animals and stimulate the secretion of digestive enzymes. Improve the body's immune and absorptive capacity.
Studies have shown that small peptides are effective in stimulating and inducing the activity of the intestinal chorionic brush border enzymes and promoting the nutritional recovery of animals. In addition, the content of lactic acid in fermented soybean meal is 3%, and the beneficial functional bacteria content of Kinpo feed starter is 1107 CFU/g. It can be considered that the reduction of diarrhea in weaned piglets is a unique quality and a variety of beneficial microbial activities formed after the fermented soybean meal is fermented by a special process. The result of the comprehensive effect of the substance.
Fermented soybean meal operation method
1. The soybean meal to be fermented is mixed with the energy feed. Energy feeds include corn and straw.
2, diluted strains. The gold baby feed starter (1Kg) and 5Kg kilogram bran mixed, and then mixed with the pods.
3. Adjust the moisture to 60% and ferment it for 2-3 days.
4. Signs of fermentation completion: fragrance, sweetness, and wine aroma.
5. Formulation principles: 51% soybean meal + 49% corn; 57% soybean meal + 43% corn; 45% soybean meal + 55% corn.
Precautions
1. When feeding from a container or bag, seal the container immediately and do not expose it for too long to avoid contamination.
2. Can not use raw materials that have been badly spoiled or have offensive odor as fermentation raw materials. If the material after fermentation is improperly stored, it will cause mildew or smell, and it cannot be fed to animals.
3. Usage and dosage of the product (fermentation product) produced after fermentation: Fermented energy feed and protein feed: Piglets are added at 20%-30% of the feed volume, and big pigs and chickens and ducks are fed at 30% of the feed volume. Add (in dry matter) for the preparation of full-priced materials; roughage can be directly used for feeding cows, sheep, cattle and sheep particularly love to eat, especially easy to grow, and can significantly increase milk production. It is also possible to add 20%-30% feed to pigs in the full price feed.

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.
We have applied the certificate of ISO, HACCP and GMP, making sure the quality of bee products.Bee Pollen,Bulk Bee Pollen,Natural Bee Pollen,Mixed Bee Pollen
