Ingredient talk about nutritional pigs gaining income
The purpose of raising pigs is to maximize profits, and the cost of feed accounts for about 70% of the total cost of raising pigs. Therefore, correctly understanding the nutritional characteristics and feed requirements of pigs, and configuring cost-effective formulated feeds are important ways to increase pig-raising efficiency. Nutrients required for pig growth and development Nutrients for pigs include crude protein, carbohydrates, fats, vitamins, minerals (including macronutrients and trace elements) and water. Under stocking conditions, pigs can obtain small amounts of minerals and vitamins through the use of green feed, arched earth, etc., but in the case of large-scale cement, except for water, these nutrients must be obtained through feed. In compound feeds, "grand" such as corn, soybean meal, and bran is usually used. Characteristics of Pig Nutrition Sow nutrition is characterized by "low pregnancy and high lactation." During pregnancy, a relatively low nutritional level is provided to prevent the sows from becoming over-fed and have difficulty feeding, the lack of milk, the increased number of suffocated piglets, and the decrease in the conception rate after weaning. In the gestation stage, feed-feeding methods are generally adopted. The lactating sows need high nutrients to feed growing piglets, and at the same time make the weight after weaning not reduce too much, so as to facilitate the estrus as soon as possible. At this stage, the diet requires digestion to reach 3200 kcal/kg, crude protein at least to 14 %the above. Newborn piglets can only digest milk fat, milk proteins, and carbohydrates in breast milk. Direct supply of corn and soybean meal-based full-priced compound feeds can easily cause diarrhea in piglets. Therefore, it is necessary to use digestible raw materials such as whey powder and puffed soybeans in the diets of suckling pigs and piglets. At the same time, it is necessary to add acidifiers and enzyme preparations that help digestion. Commonly used feed ingredients for pigs (1) Corn and corn are the main energy feeds in China. In the preparation of pig feed, corn is used as the main part of the ratio, and a variety of nutrient balance is implemented around it to supplement the protein. Because corn contains more unsaturated fatty acids, the ground corn flour is prone to rancidity and deterioration, and it is not suitable for long-term preservation. Newly-listed corn has high moisture content and is susceptible to mildew during storage, and aflatoxin produced after mildew. Large sex, easy to make pig poisoning, should be given great attention. (II) Wheat Bran Wheat bran is laxative, and should be avoided in suckling pigs' diets. Pigs and medium and large pigs can use 5–15%. Wheat bran is a good raw material for control of middle-aged pigs, constipation, and pregnant mothers. Pigs may account for about 20% of diets, and sows in lactating sows should not exceed 20% in order to avoid low energy and affect lactation and sensation. (c) Soybean meal The use of soy meal should be restricted in suckling pig diets, and should not exceed 25%, because soybean antigen in soybean meal can cause diarrhea in suckling piglets and weaned piglets, and the combined use of a portion of expanded soybeans will achieve better results. (4) Gossypol contained in cotton aphid and cotton aphid has a certain toxic effect on pigs, so the amount of cotton aphid used should be controlled. Under normal circumstances, cottonseed meal cannot be used in the diets of suckling pigs, piglets and sows, and no more than 6% of the growth of growing pigs and finishing pigs. (5) The astringent taste of rapeseed meal will affect the palatability and protein utilization and hinder the growth of pigs. Therefore, pigs and piglets do not have to use vegetable meals. It is advisable to add 3%-5% to the growth of growing pigs, finishing pigs and sows. (6) Peanut cake (cake) Peanut cake is a good source of protein in pig feed. Pigs prefer eating, but they should not be fed more than 15%. Otherwise, the body fat of pigs will become soft and affect carcass quality. (7) Fishmeal and fishmeal are excellent feed ingredients for suckling pigs and piglets, but due to higher prices, some farmers and feed mills use less and less fishmeal. When possible, use some fishmeal as much as possible, which will help the production performance of pigs. Principles for the preparation of pig diets 1. To meet the nutritional needs of pigs to ensure the balance of nutrition: Pigs need to get heat, protein, minerals, vitamins and other ingredients from the feed. In recent years, the feed formula design of pigs has used the "available amino acid balance", "mineral balance", "acid-base balance" and other theories, so that nutrition is more reasonable and formula is more economical. 2. Safety: First, it refers to the use of raw materials that do not use mildew, spoilage, or contamination, such as corn, which may cause Aspergillus flavus, and produce aflatoxins. The fluorine content of dibasic calcium phosphate must not exceed the standard, and bovine baits cannot be used in boar feeds; It refers to the use of drugs and additives that are not easily used and are harmful to the human body, such as "Clenbuterol." 3. Palatability: Good palatability is a problem that should be fully considered when formulating feeds. In addition to ensuring the freshness of feed ingredients, seasoning and flavoring agents can be added to the diet of suckling pigs and piglets. 4. Economy: The best formula for nutrition is not necessarily the most economic formula. The full-price compound feeds produced, whether sold or used for personal use, should be considered economically. Method for preparing pig diet formula 1. Preparation data (1) Kind of raw materials. (2) Nutritional content of various raw materials and possible toxic and harmful substances: This is the basis for formulating pig diets. If 40% of the crude protein of the pig is used for general enrichment, the protein content of soybean meal is calculated as 44% and 43%, and the final formulation cost will be very different. 2, design formula: According to the known nutrition standards and nutrient content of various raw materials, reasonably determine the proportion of various raw materials in the formula, so that the formula of digestion, crude protein, calcium, phosphorus, salt, lysine, methionine just To achieve nutritional standards but not much, thereby reducing costs. When designing formulas, be sure to pay attention to the scientific nature of the formula. Never add any raw materials at will.
