The use of premix can improve the nutritional value of formulated feed. However, premix is an intermediate product in the production of formulated feed. The variety and requirements of feed vary greatly. It is difficult to completely match the production of all kinds of full price feed even though the premix is considered carefully. In order to make good use of live premix, the following two points should be paid attention to

1、正確選擇型號 預混料按照不同豬種及其不同生長發(fā)育階段的營養(yǎng)需要而科學設計的，因此用戶應根據(jù)豬的實際情況選擇不同階段的預混料品種。有的用戶為了貪圖一時便宜，用中豬料代替小豬料，豈不知“小豬差1斤，大豬差10斤”，小豬階段營養(yǎng)不足，影響了豬的后期發(fā)育，這種做法是得不償失的。

1. The correct type of premix is scientifically designed according to the nutritional needs of different pig breeds and their different growth and development stages. Therefore, users should select different premix varieties at different stages according to the actual situation of pigs. Some users, in order to seek temporary cheap, use medium pig feed instead of small pig feed. They don't know that "the difference between small pig and big pig is 1 jin, and that of big pig is 10 jin". The lack of nutrition in piglet stage affects the later development of pig. This practice is not worth the loss.

2、嚴格劑量配合飼料 很多飼養(yǎng)戶使用預混料時常常隨便改變配方，有的用戶為降低成本隨意降低預混料在配合料中的比例，造成各項營養(yǎng)指標不能滿足豬各個時期的生長需要，有的用戶則任意加大預混料的比例，這樣不但增加了成本，而且造成中毒現(xiàn)象。更有甚者將預混料當“味精”，在全價飼料中再添加小包裝，以破壞了飼料的“全價性”。

2. Strictly recommended dosage of compound feed Many breeders often change the recommended formula when using premix. Some users reduce the proportion of premix in the mixture to reduce the cost, which results in that the nutritional indicators can not meet the growth needs of pigs in different periods, and some users arbitrarily increase the proportion of premix, which not only increases the cost, but also causes poisoning. What's more, they regard premix as "monosodium glutamate" and add small packages to the full price feed, thus destroying the "full price" of feed.

如何評估豬用預混料的優(yōu)勢，重在實際使用效果，正確使用既能降低生產成本又能增加養(yǎng)殖收益，值得推廣和應用。

In addition, it is worth to evaluate the advantages of using heavy feed in pig production, and how to use it correctly.
