1 selection and processing of raw materials 1.1 Selection of feed ingredients: The first measure to optimize feed costs should be the correct selection and use of feed ingredients. The price of feed ingredients is not the main choice, but the use value of feed ingredients. Taking the most common soybean meal in feed as an example, many of our feed companies choose 43% protein soy meal in broiler formula and think that 43% protein is cheaper. However, we have neglected several important factors: First, the main difference between 43% protein soy and 46% protein soybean meal is the difference in the content of soybean hull, which is difficult to be digested by poultry, while the content of soybean meal is contained. Very high mannan, affecting the intestinal absorption of glucose. The digestibility of 46% protein soybean meal is higher than 43% peptone, and the formulation space is saved in the formulation. However, the difference between the two types of soybean meal is only 150 yuan / ton. In the broiler feed formula, the recipe system automatically selects 46% protein of soybean meal, and we only purchase 43% of the soybean meal. This invisibly increases feed costs while reducing the quality of the feed. Therefore, in some large feed enterprises, only high-protein soybean meal can be used in the diet of growth and finishing animals such as broilers. The choice of cotton aphid is the same. It is recommended to use high-protein cotton aphid, because the difference between low-protein cotton aphid and high-protein cotton aphid is more cotton lint and cotton crust. Cotton lint and cotton crust only affect the digestibility of feed protein. . Of course, the choice of feed ingredients should also consider the effective energy value of feed ingredients, anti-nutritional factors in feed and other indicators. 1. 2 Processing of raw materials: The purpose of feed raw material processing is to eliminate the effects of some unfavorable factors on the animals and improve feed quality and feed safety. Correctly, the processing and storage of feed ingredients can also reduce the cost of feed for enterprises. The commonly used feed ingredients are mainly processed as follows: Screening and clearing of corn: Corn is the most commonly used raw material in feed. The content of impurities and mycotoxins in corn will affect the digestibility of feed nutrients. In the process of harvesting and drying, corn will contain more impurities such as dust, stones, corn husks, etc. These impurities do not contribute to the nutrition of the feed, and the mycotoxin content is high. These impurities can be removed by sieving and cleaning before entering the warehouse, and the broken grains and mildew granules in the corn are also removed, which effectively reduces the content of mycotoxins in the corn and improves the quality of the feed. Soybean puffing: The price of fats and oils has been at a very high level recently. The cost of adding fats to broiler feeds is high, and there is a risk of fat oxidation using low-priced feed blends. However, the use of puffed whole-fat soybeans not only provides high-quality protein, but also provides high fat with a metabolizable energy of up to 3700 kcal/kg. The oil of the puffed soybean is fresh, and the puffed soybean has a special aroma, which can improve the palatability of the animal. If the feed company has puffed soybean conditions, it can save costs from the perspective of formula cost. 2 Optimization of feed formula and micro-finishing 2.1 Optimization of feed formula In the process of technical service, I noticed that some companies have not fully utilized the advantages of feed formula software to optimize feed formula. Many colleagues still use Excel spreadsheets to calculate formulas. Although this method is convenient for a single material formulation, these methods cannot be linearly calculated. Perhaps the difference in formula cost between linear calculation and hand calculation is only 5-10 yuan/ton. However, the profit of poultry feed is very small, 5-10 yuan is already a big number for a feed mill with a monthly output of 5,000 tons. When I helped some small feed companies adjust their formulas, they often found that they should increase the amount of soybean meal and crystal amino acid added at the same cost, but these companies use low-priced chowder, they think that they use low-cost raw materials. It will be cheaper, but it will not, but it will reduce the quality of the feed. Therefore, the scientific use of feed formula software, timely adjustment and management of the database is extremely important for optimizing the formulation of poultry feed. 2.2 The micro-preparation of feed formula Many people believe that the feed formula is stable and the feed is stable. It can be said that this is a wrong view, because the source of feed ingredients and nutritional indicators are changing, and the feed price is also changing. If the corn moisture purchased in different seasons is different, the metabolic energy value is different, and if the formula ratio does not change, the feed quality changes. The correct method is: every week (according to the change cycle of raw materials), according to the moisture, protein, ash, fiber and other indicators of each batch of feed ingredients, adjust the raw material database, in order to ensure the original nutritional value of feed and the appearance of feed and other factors Fine-tuning the recipe. This kind of feed is more stable in quality and effect. Modern Rugs and Carpets,Hotel Carpet,Luxury Hotel Carpet Printed Carpet Co., Ltd. , http://www.hot-carpets.com
