Farmers' own preparation of feed can not only make full use of local feed resources, effectively reduce the cost of feeding, but also have better adaptability when feeding local livestock and poultry breeders. It can make meat and eggs more flavor and satisfy consumers' pursuit of green and natural. The demand for fashion can better dominate a consumer market. However, in the specific operations, many farmers lack the technology and equipment for feed allocation. Self-provisioned feeds tend to have unbalanced nutrition and the aquaculture benefits are not ideal. To this end, the author summarizes the 10 tactics that need to be mastered for self-provisioned feeds. The following introductions are presented here, hoping to provide assistance to the majority of farmers. Energy unit In the nutrient requirement scale, digestive energy (DE) is a unit of energy suitable for pigs, metabolic energy (ME) is suitable for poultry, and net energy (NE) is applied to cattle. The energy unit used in the past was kcal (KC), which has been changed to MJ or KJ. The conversion relationship is: 1 kcal (KC) = 4.184 kJ (KJ) 1 megajoule (MJ) = 1000 kJ (KJ) Need to adjust the composition The nutrients that need to be adjusted mainly include four major items: energy, crude protein, amino acids, and minerals (mainly including salt, calcium, phosphorus, etc.). Need to give priority to the supplement of amino acids According to the importance of amino acid ranking, the priority of hair-producing livestock is: cystine, cysteine, methionine; rabbit: methionine, cystine, lysine; pig: lysine, methionine, color Families; Poultry: Lysine, Methionine, Tryptophan, Threonine, Cystine. Adjust amino acids according to feed characteristics The lack of lysine and arginine in corn, but more methionine; more lysine in the bean cake, but the lack of methionine; lysine missing in the cotton cake, which methionine, tryptophan was significantly higher than the bean cake Fishmeal contains a variety of amino acids, especially lysine is very rich. Pay attention to essential fatty acids The three fatty acids must be supplied by feed: 18 carbondienoic acid (linoleic acid), 18 carbonic acid (linolenic acid), 20 carbonic acid (arachidonic acid). Add vitamins Livestock and poultry do not generally need to be supplemented with fat-soluble vitamins (including A, D, E, and K). However, vitamin E has the function of replacing selenium. In areas where selenium deficiency occurs, vitamin E may be added in the feed of livestock and poultry. Pigs and poultry need to add vitamin B family, including vitamin B1, vitamin B2, vitamin B6, vitamin B12, as well as biotin, pantothenic acid, niacin, choline, inositol, folic acid and so on. Appropriate amount of minerals Although the amount of minerals is not much, it is much higher than vitamins. Therefore, there should be room for adjustment in the formula. Pork chickens are more sensitive to salt, with a typical dose of 0.4% and a standard dose of 0.37%. High-grade laying hens have high requirements for calcium, which can reach 8%. To meet the needs of calcium, they cannot be added in feed because such a large amount of calcium affects the nutritional balance of feed and the feed intake of chickens. It can be used separately. The feeding trough is made up exclusively of crushed shells and broken bones can also be used. Rabbits are better tolerant to calcium, but not to high phosphorus, should control the phosphorus content. Add animal protein Blood meal and feather meal are good animal protein feeds. The fishmeal is better, but the price is higher, the amount should not exceed 5%, generally 1% to 2%. The amount of cotton cake should not exceed 5% to prevent the accumulation of gossypol poisoning. Silkworm cocoons should be fully utilized in the silkworm producing areas, and freshwater fish and shrimps can be fully utilized in rivers and lakes. Insects and maggots contain antibacterial peptides and chitin, which can not only improve the disease resistance of chickens, but also prevent the damage of E. coli and Aspergillus. It can also make the color of eggs deeper, cholesterol lower, and the quality of eggs improved. Rational use of local resources Powder residue has high water content, contains more crude fiber, and should be dried after being used in a certain proportion. Bean curd residue contains anti-trypsin, which affects the absorption of protein by livestock and should be used after cooking. Sorghum contains more tannins, and it is generally not more than 10% to control the dosage. Too much dosage can cause constipation. Sweet potato starch contains more starch, pigs digestible raw food is not high, should be cooked after cooking. The loquat leaf contains vitamins and proteins. It can be dried and ground, and is fed into the feed for pigs and poultry at a dosage of about 2%. Carefully selected antimicrobial agents The antibiotics approved for use in feeds in China include bacitracin zinc, enramycin, virginiamycin, and tylosin (the imported product is called tylosin phosphate). Farmers can choose appropriate antibacterial Chinese herbal medicines such as honeysuckle, wild chrysanthemum, dandelion, Houttuynia, violacea, herb, turmeric, garlic, and onion leaves as additives according to the distribution of local Chinese herbal medicines.
