Self-matching chicken feed key technology
In the production of chickens, small and medium-sized farmers are mostly self-contained feeds, which not only can make full use of local feed resources, but also greatly reduce the cost of feeding. Most farmers are based on experience and feed nutrient content, first determine the proportion of various types of feed in the diet, and then through calculations, adjustments, so that the nutritional indicators in the formula are close to the feeding standards. However, due to factors such as personnel quality, technical level and processing equipment, the prepared feed is not scientific, and there are still certain quality problems, which affect the performance of chicken production. Here, we will briefly introduce several key technical links of chicken feed for reference by farmers.
1 Strictly control the quality of raw materials
Raw materials are the basis of the quality of the finished products, and the quality directly affects the quality of the feed. The raw materials come from all directions, and the nutrient content will vary greatly depending on the origin, the maturity at harvest, the processing method, and the moisture content. Especially in the season of raw material shortage, the variety is mixed, the quality is poor, and the noisy is serious. It is necessary to strictly control and pay attention to quality. If you have the ability to detect yourself, you should not rely on sensory identification. If you do not have the ability to detect, it is best to entrust a test to the department with the ability to detect to determine the level of nutrients. In addition, the premixed material added to the raw material has poor stability and the storage time should not be too long, otherwise it will cause loss of nutrients and mildew, and it is best to use it now.
2 Develop a scientific feed formula
2.1 The formula should be relatively stable. The feed formula in a certain growth stage must be relatively stable. It is not possible to change the variety and proportion of the raw materials at will. Otherwise, the chickens are in a state of stress, which affects the growth and production performance of the chicken.
2.2 Reasonable matching of raw material selection Generally, it can be selected according to the formula recommended by the additive manufacturer, combined with the varieties of self-prepared raw materials. Special attention should be paid to the ratio of protein and energy. Improper proportion will affect the utilization efficiency of nutrients and increase the cost of feed. In addition, we must pay attention to the ratio of calcium, phosphorus, vitamins and trace elements to maintain the balance of nutrients.
2.3 It is necessary to flexibly adjust the different varieties of the chicken and the nutrients required for different growth stages, so the formula also changes with each stage. In addition, it should be adjusted according to environmental changes, shortage of raw materials, price level, quality level and other factors. In the hot summer, the feed intake of chickens is reduced, so the nutrient concentration of the diet should be increased, especially the protein content; the temperature in winter and spring is low, the light is insufficient, the energy level is relatively high, and the chicken multivitamin is added to the diet.
2.4 Pay attention to the economic formula of the formula. The choice of feed should be based on the principle of economy. Try to use nutrient-rich and low-cost feeds according to local conditions. You can replace some soybean meal with peanut meal and cottonseed meal, and replace imported fish meal with yeast powder. It is also not possible to buy inferior raw material feeds only for the sake of cheapness.
3 Processing and storage of
3.1 Weighing should be accurate with special precision weighing tools (such as balance) to minimize weighing error.
3.2 The smashing of feeds with different granules of different sizes is different in the digestive tract digestion time and the size of the action area, and the digestibility is also different. The feed granules are too thick, which is not conducive to the digestion of chickens, and is easy to picky eaters, resulting in waste; if the smashing is too fine, the palatability is poor, affecting the feed intake. The particle size should be adjusted according to the age of the chicken. The requirements for the feed of broiler chickens and laying hens should be 99% through the 2.8mm woven sieve; the requirements for the broiler and laying hens should be 99% through the 3.35mm woven sieve; The laying hens are required to pass through a woven sieve with a diameter of 4.4 mm at 100%.
3.3 Mixing should be evenly uniform, the nutrient content in the feed is unevenly distributed, and the nutrients taken by the chicken are not surplus or insufficient, and it is easy to cause nutrition and metabolism. Therefore, it is necessary to dilute step by step and mix repeatedly, and it is better to purchase the mixer under certain conditions.
3.4 Storage should be completed in a special storage room, and the temperature and humidity should be properly controlled, can not be stacked, and regularly kill rats, insects and so on. The storage time is preferably 3 days in summer and 1 week in winter. The time is too long and it is easy to cause loss of nutrients.
4 Strengthen quality control
After the ingredients, the various nutrients should be tested for compliance with the formula design criteria in order to make adjustments that best match the criteria. After adjustment, it should be tested in small groups. If the effect is good, then the large group should be fed to ensure the nutrition of the feed.
In short, the process of self-contained chicken feed is a process of continuous improvement and continuous improvement. When formulating ingredients, we must pay special attention to the formulation and processing of the formula. After the distribution, it must be tested and continuously improved in practice, so that the prepared feed can meet the nutritional needs of chicken growth and development, in order to maximize economic benefits. .
