Concentrated feed is a kind of semi-finished feed which is scientifically and reasonably mixed with various protein raw materials (such as soybean meal, rapeseed meal, fish meal, etc.) and a certain proportion of minerals and additives according to the requirements of feeding standards. It is simple and convenient to use, as long as the reference formula on the label is used, and the self-produced corn flour and bran can be flexibly matched, but not directly Feed. Xiaobian found that some farmers, especially free range farmers in the selection of a lot of improper, this paper puts forward several aspects of small retail Pig concentrate selection need to pay attention to, for your reference
1. Distinguish type and stage, select material reasonably
The most prominent blind use of raw materials for small retail investors is to use Pig concentrate mixed with corn flour instead of pig pellet or Pig concentrate. The result is just the opposite. It does not save cost. On the contrary, it leads to more thinning of suckling pigs, malnutrition, slow growth, and even death of edema disease. Different kinds of livestock, different economic types and different growth stages have different requirements for various nutrients. There are many kinds of concentrated materials prepared according to their different nutritional requirements. Therefore, in order to achieve the feeding effect, we should carefully understand the applicable objects of the products, and choose the appropriate concentrate according to the number of livestock and poultry and the variety.
2. According to the reference proportion, reasonable ingredients
Concentrated feed is a kind of semi-finished feed, which should be made into full price feed according to different types and stages of livestock and poultry. However, at present, many farmers do not use concentrated materials at one time. Instead, they use a kettle cover or bowl to scoop up some concentrated materials and mix them with some corn flour and bran. It is not scientific to mix them in proportion. Therefore, in the preparation of the full price material, it should be prepared according to the reference proportion on the label, flexible application, and do not add too many other additives at will.
Concentrate feed and corn and other energy feed must be mixed evenly. For large-scale households, the materials are processed and mixed by machine, while for most free range households, the materials are mostly mixed by hand. The method of manual mixing is: first, mix part of the energy feed with the concentrated material, fully stir to achieve uniformity, and then add part of the energy feed, fully stir and mix evenly. In this way, after mixing and stirring for many times, a uniform and uniform full price feed is prepared. If the mixture is not uniform, it can cause malnutrition of livestock and poultry and affect the feeding effect.
4. Avoid heating the batch
The full price feed made from concentrated feed, mixed into hot cooked food, heated or fermented, will cause the loss of nutrients and seriously damage the nutritional balance, especially the loss of vitamins, which directly affects the performance of livestock and poultry production. When feeding, the raw material should be fed dry or mixed wet.
