How to use feed to a greater extent and price breeding costs, the following points are for reference:
Fine processing
Mechanical processing reduces feed waste and improves palatability. After the roughage is cut short, it is easy to mix and chew. After the concentrated feed is ground, it is conducive to the thorough mixing of the digestive juices. Specific fineness requirements: pigs should be less than 1 mm, cattle and sheep can be 1-2 mm, horses and small livestock can be 2-4 mm. The sweet potato leaves used for feeding pigs are soaked to dissolve impurities. The moldy dried melon can quickly dissolve the toxic substances after soaking. After cooking, dried melon or sweet potato noodles can further improve the palatability and expand the crude fiber, which is conducive to the penetration of digestive juice.
Chemical treatment can improve the nutritional value of roughage. The commonly used chemical treatment methods are alkalization or ammoniation, which uses the action of alkaline components to destroy the structure of lignin in forages, dissolve silicates in it, and convert those nutrients related to lignin such as cellulose and hemicellulose. The liberation of vegetarian food increases the nutritional value of the feed, and animals also love to eat.
Biological treatment can promote material transformation, improve nutritional value and digestibility. After the feed is saccharified, the nutrients are degraded, and the palatability is greatly improved, which is more conducive to the digestion and absorption of nutrients. After the feed is fermented, the crude fiber is degraded, and it can also produce vitamin B family, organic acids, alcohols and other aromatic and stimulating substances, improve digestion and nutritional status, and further increase productivity.
Reasonable ratio
The nutritional components of a single feed are not perfect and cannot meet the nutritional needs of livestock and poultry. The use of compound feed can achieve the effect of learning from each other's strengths and complementing the shortcomings, and can make full use of the nutrients in each component, especially the addition of various essential amino acids, which can greatly improve the feed utilization rate. . The microorganisms in the rumen of ruminants can use inorganic nitrogen to synthesize bacterial protein. In order to improve the synthesis of bacterial protein, 0.02%~0.05% urea can be added to the ruminant animal feed, and 1 kg of urea can replace 6~7 kg of bean cakes . Broiler chickens grow and develop very fast. Adding 1% to 5% animal fat in the diet has a good effect on improving the utilization rate of feed.
