what should be paid attention to when farmers make chicken feed themselves

What should be paid attention to by chicken farmers when they are equipped with chicken feed? Follow us and give you tips in the following:

1. Suitable breeding standards.

The nutritional standards required for different breeds of chicken are not the same, even the nutritional standards of the same breed of chicken at different stages of growth are not the same. Breeders, laying hens, and broilers also use different nutritional standards. Before formulating the feed, according to the breeds, age, growth and development stage, production purpose and production level of the chickens to be fed, the appropriate breeding standards should be selected to determine the nutrient requirements of the chickens, and then combined with the feed supply. To meet the production needs of chickens, to improve the conversion rate of feed and feed compensation, to maximize the performance of chicken production.

2. The formula should be reasonable.

General farmers can refer to the recommended formula of the feed manufacturer, professionals can design the formula according to the raw materials they own. The formula should be scientific and reasonable, and the variety of raw materials should be diversified. Because the stomach volume of the chicken is small, the digestive tract is short, and the feed stays in the digestive tract for a short period of time. In the formulation, the nutrient level of the feed should be considered, and the palatability, bulk density, digestibility and nutrients of the feed should be considered. Balance. To ensure that chickens can not only eat, but also meet the nutritional needs, especially egg and broiler chickens should use high-energy, high-protein raw materials. At the same time, in order to ensure a comprehensive balance of feed nutrition, it is necessary to use several raw materials. In order to give full play to the nutritional complementarity between various raw materials, the purpose of improving feed utilization can be achieved.

3. Use local feed resources.

When selecting raw materials, it is necessary to adapt to local conditions and make full use of the existing local feed ingredients, which not only saves a lot of freight. Reduce costs, while also promoting the local digestion of local raw materials, so that the local industry cycle is healthy – for example, when corn prices are higher than wheat. The formula can be adjusted to add a complex enzyme. Use wheat instead of corn.

4. Strictly shut the chicken feed ingredients.

The quality of chicken feed ingredients is directly related to the effect of feed preparation. When purchasing feed ingredients, strict attention should be paid to the quality of raw materials. Fresh raw materials should be used. It is strictly forbidden to use moldy and deteriorated raw materials; Doping materials that make false and unstable quality; use materials containing toxins and harmful substances with caution. For example, cotton cakes contain gossypol. The dosage should be strictly controlled and should not exceed 5% of the diet. For unconventional vegetable protein feeds such as castor cake. Due to the low digestion efficiency, the general addition amount is not more than 3%, and it is best not to use it. As an energy feed, the amount of corn must be controlled within 14%.

5. Suitable feed additives.

When selecting feed additives, it is necessary to pay attention to the comprehensive and effective variety, economic stability, and safety. Amino acids, vitamins, mineral elements, pharmaceutical additives, enzyme preparations, etc. are indispensable additives for chickens. They should be added according to the product variety, growth stage, production purpose and production level according to the product instructions to avoid waste and cause chicken poisoning. In particular, pharmaceutical additives must control the amount of use and time of use. Add phytase or complex enzyme preparation to improve the quality of feed and reduce feed cost. In the summer heat, garlicin can be added to prevent bacterial diseases and improve the palatability of feed; adding betaine can relieve heat stress. When a large number of new corns are marketed in the fall, proper addition of phospholipids can make up for the lack of energy levels. In addition, all additives must be selected from reputable manufacturers, and the same manufacturer’s products should be used as much as possible so that the feed quality will be better.

6. To limit the crude fiber content.

Due to the digestive characteristics of the chicken, attention should be paid to limiting the content of crude fiber in the preparation of the feed. The chicken has no teeth, and the feed that feeds enters the esophagus without chewing and reaches the sac. After soaking in the sac for a short time, it enters the stomach and stomach. All foods only rely on the contraction of the muscles to grind the feed instead of the chewing of the teeth. Therefore, chickens, especially chicks, have poor digestion ability for crude fiber. Therefore, the content of crude fiber in the feed should not exceed 3% for chicks, 4% for broilers, and 7% for broiler chickens and laying hens.

7. Mix well.

Pay attention to the mixing uniformity when processing the feed. Do not extend or shorten the mixing time as required by the mixer. Because good mixing uniformity is one of the keys to improving feed utilization. Since the full-price materials are mostly powdered (the farmers generally do not granulate themselves), many raw materials such as corn and soybean meal should be pulverized, and the particle size is generally 1.5 to 2 mm. In the processing process, all kinds of raw materials should be accurately weighed according to the proportion of the formula, and the mixing time should be controlled to prevent uneven mixing or feed classification. For the addition amount of less than 1%, such as multi-dimensional, multi-mine, etc., it can be pre-mixed before being added, and mixed with an equal amount of bran (carrier) to ensure uniformity. It should be noted that choline cannot be directly mixed with multivitamins because choline has hygroscopicity and strong oxidative properties, which lowers the potency of vitamins.

8. Maintain the stability of the diet and adjust it in a timely manner.

Pay attention to the relative stability of the diet when adopting the stage. Chicks and laying hens are very sensitive to changes in the diet, and the diet formula should not be changed frequently. Diet changes at different stages should pay attention to the gradual transition, avoid mutations, so as not to cause the loss of chicken feed intake, food refusal or indigestion. At the same time, according to different seasons, different production stages, different production levels and feedstock price changes, the diet formula should be adjusted appropriately. If the summer heat is hot, the feed intake of the chicken is reduced, and the protein content in the feed needs to be increased by about 10%; The energy consumption of the chicken to maintain body temperature is increased, and the energy in the feed should be appropriately increased.

9. Scientific storage of feed.

The preparation of full-price feed should follow the principle of “current use”, generally with the amount of “7 to 10 days of diet. The feed storage time should be short in summer high temperature, generally 3 days is appropriate; winter can be relative storage time Longer, but not more than 2 weeks. Because the mixed feed has high humidity and poor air permeability, the long time after crushing and mixing will cause loss of nutrients such as fat and vitamins. According to the data, the feed storage time is 1 month, and the vitamin effect The price will be greatly reduced. In addition, especially in summer, the environment of high temperature and high humidity can easily make the feed moldy and deteriorate. It is necessary to ensure that the storage room for storing feed is ventilated, protected from light, dry, anti-mouse and anti-pollution. The bagged feed should be off the ground. Stacked from the wall, it is best to use the wooden board to vacate the ground more than 20 cm, and do not pile too high and too heavy.
