For farms with a size of 300,000 laying hen, the goal of feed quality pursuit is a long peak egg production period, high egg production rate, good egg quality, and good feed digestion utilization rate, which can improve the breeding environment of the laying hen farm and improve the laying hen breeding economic and social benefits. How to ensure that the feed meets the above goals, based on years of technical formula service experience, Ruiqi summarized the feed ingredient process of the layer farm.
The process of the farmer's own ingredients of the layer farm generally includes crushing section and mixing section.
Crushing can increase the contact area between feed and digestive enzymes, which is conducive to the digestion and absorption of nutrients, but the crushing size is too coarse and too fine. Many raw materials such as corn and soybean meal (flakes) need to be crushed, and the grain size of the diet should be controlled according to different feeding stages.
The purpose of feed mixing is to ensure that each component can exist uniformly in different parts. The variation coefficient of the mixing uniformity of the compound feed mixer is required to be less than 7%. The equipment is fixed, and the factors affecting the mixing effect mainly include mixing time, fullness factor, feeding procedure, etc.
The mixing time should be suitable. Different mixing machines and methods have different mixing times. The optimal mixing time of the batching equipment of professional feed factories is generally within 2 minutes, while the mixing equipment purchased by farmers is generally 5-10 minutes. Wait. Because in the process of material mixing, the mixing effect quickly reaches the optimal mixing uniform state with the extension of the mixing time. However, when the materials have been fully mixed, if the mixing time is extended, the mixing uniformity will decrease instead. In short, the mixing time is too short to achieve full mixing, and too long will cause separation and also affect the mixing quality. Zhengchang Feed Technology can occasionally measure the mixing uniformity for customers to determine the best mixing time for customers.
In the order of feeding, generally 80% of the components with large proportions are first input into the mixer, then the materials with small proportions are input, and then the remaining 20% of the large components are input, so that the remaining large The components are covered on the micro components (premix), which can prevent the micro components from clumping into the dead corner or bottom of the mixer and other difficult to mix, and can avoid the flying loss of the micro components. If the mixer is equipped with a spray grease device, the liquid component should be added after mixing the powder for a period of time and mixed with the powder.(The fullness factor refers to the ratio of the volume of the material loaded into the mixer and the volume of the mixer, and its size affects the accuracy and speed of the mixer.)
The equipments required for feed ingredients of over 300,000 layers include:
1.Feed Hammer Mill(10-13T/H,110KW)
2.Animal Feed Mixing Machine(2000KG/BATCH,30KW)
