1. Select the appropriate feeding standards. Be sure to pay attention to the selection of feeding standards before self-provisioned feed. You must select the appropriate feeding standards and determine the nutritional requirements according to the breed, age, growth stage, production purpose, and production level of the chickens. The amount, combined with the amount of feed, meets the needs of the chicken, and aims to increase the conversion rate and feed reward of the feed and maximize the growth and production performance of the chicken.
2. The formula should be reasonable. The chicken has a small stomach volume, a short digestive tract, and a short time for the feed to stay in the digestive tract. According to the characteristics of the chicken's digestive physiology, the formula should be rational and the variety should be diversified. It is necessary to consider the nutrition level of the feed, and also to consider the balance between palatability, bulk density, digestibility, and nutrient content of the feed. To ensure that chickens can eat, but also to meet nutritional needs, especially for chickens and broilers to use more high-energy, high-protein raw materials; at the same time to ensure the overall balance of feed nutrition, we must use more than a few kinds of raw materials in order to make full use of each Complementary effects of nutrition between raw materials, so as to achieve the purpose of improving feed digestion and utilization.
3, make full use of local feed resources to choose raw materials should pay attention to the reasons, according to the time, make full use of local sources are guaranteed, cheap and high nutritional value feed, try to save transportation costs and reduce feed costs.
4, to ensure the quality of feed ingredients in the purchase of feed ingredients should pay attention to the quality of raw materials. Fresh raw materials should be used, moldy feedstuffs must not be used, attention should be paid to the identification of feed ingredients, and the use of raw materials containing toxins and hazardous substances should be strictly prohibited, and raw materials containing toxins and harmful substances should be used with caution. Strictly control the dosage not to exceed 5% of the diet. Self-provisioned feed should follow the principle of using with the use of, generally a 7-10 days with the amount of food, because the mixed feed is relatively high humidity, poor ventilation, crushed and mixed for too long will result in loss of fat, vitamins and other nutrients Especially in summer, high temperature and high humidity can easily become moldy. Feed storage should ensure indoor ventilation, protection from light, drying, rodent control and pollution prevention. The bagged feed must be separated from the wall by stacking, and it is best to use a wooden frame to take more than 20 centimeters from the ground. The feed should not be piled too high and overly heavy.
5, the selection of suitable feed additives in the selection of feed additives should pay attention to the full variety, dose standards. Amino acids, vitamins, minerals, trace elements, drug additives, and enzyme preparations are indispensable additives for chickens. Different additives and different proportions are selected according to the breed, growth stage, production purpose, and production level of the chicken. Must be added according to the product instructions to avoid waste and poisoning, especially drug additives must control the amount of use and use time to prevent poisoning. Add enzyme preparations or compound enzyme preparations to improve feed quality, increase digestion and absorption rate, improve production performance, reduce the occurrence of diseases, reduce feed costs, and increase the economic efficiency of raising chickens.
6, limit the crude fiber content of chickens without teeth, feed into the esophagus without chewing to reach the crop, after a short period of time in the crop, soaked into the muscle stomach, glandular stomach, rely on muscle contraction of the stomach to make food and sand grinding alternative to the chew of the teeth effect. The digestive characteristics of chickens determine the need to limit the amount of crude fiber in the feed formulation. In particular, chicks have poor digestion of crude fiber, so the content of crude fiber in the diet is not more than 3% for chicks, 4% for broilers, and 7% for broilers and layer chickens.
7, mixing should be uniform in the feed processing should pay attention to mixing. Doing a good job in feed processing is one of the key measures to improve feed utilization. Most of the ingredients are powdered, corn, soybean meal and many other raw materials to be crushed, and its particle size is generally 1.5-2 mm. During processing, all raw materials must be accurately weighed according to the formula proportion, and the mixing time should be well controlled to prevent uneven mixing or feed grading. It should be reminded in particular that additives with additive content of less than 1% should use multiple stages of premixing, ie mixing with a small amount of auxiliary materials and additives first, then mixing with more auxiliary materials, and mixing with the entire diet. Uniform, otherwise nutrient deficiencies or poisoning may occur due to uneven feeding.
8. Maintain the stability of the diet and timely adjust the relative stability of the rations during feeding. Chicks and laying hens are sensitive to the changes in the diet. The diet formula should not be changed frequently. The rations in different stages should be changed. Pay attention to the gradual transition, avoid sudden changes, resulting in a decline in feed intake, food refusal or indigestion, affecting the production level. At the same time, according to different seasons, different production stages, different production levels and changes in the price of feed ingredients, appropriate adjustments to the formula of the ration, such as summer heat, the chicken's feed intake decreased, need to increase the protein content of feed about 10%; winter cold, Chickens are used to maintain the increase in body temperature energy consumption, and the energy in the feed should be appropriately increased. In order to prevent feed wastage, cost increase, and the occurrence of metabolic diseases, it is necessary to timely adjust the diet formula according to changes in actual conditions.
