However, this feeding milk has the following disadvantages: the ingredients in the formula are complex, which brings a considerable workload to the preparation process
In addition, the feeding milk is sterilized by high pressure, and a large amount of essential nutrients such as protein, serum, and vitamins are lost during the sterilization process, resulting in growth retardation and low survival rate of suckling mice

Embodiment
[0023] According to the specific raw material composition in Tables 1, 2, and 3, artificial feeding milk for sterile rats was prepared, and the suckling rats were divided into 0-6 days, 7-15 days, and 16-21 days according to the birth age of the suckling rats to feed the sterile rats.
[0024] Table 10-6 days group
[0025]
[0026]
[0027] The above-mentioned examples 1, 2, and 3 are formulas routinely used for artificial lactation of suckling rats at birth age of 0-6 days. Example 1 is used for newborn suckling rats. Since the digestive ability of suckling rats is weak at birth, the artificial milk preparation is relatively dilute and easy to digest. According to the changes in the digestion conditions of suckling mice, the formulas of Example 2 and Example 3 can be gradually replaced.

Abstract
The invention relates to a milk product for artificial animal feeding, which aims at providing improved sterile artificial rat feeding milk, which is divided into three stages according to the growth and development requirements of suckling rats and respectively consists of rabbit milk, newborn calf serum, infant formula milk powder and water. During the preparation, the rabbit milk and the infant formula milk powder are transmitted into a sterile isolator after the radiation sterilization through cobalt 60, the water and the newborn calf serum are transmitted into the same sterile isolator after high-pressure sterilization, and the materials are uniformly and proportionally mixed. Because the recipe ingredients are simpler, only four preparation ingredients are adopted, the preparation operation is simpler, and in addition, the nutrition is overall. After the radiation sterilization, the nutrition loss is minimum, the newborn suckling rats have good digestive absorption, the gastic emptying is fast, the growth and the development are good, and in addition, the survival rate is higher. The sterile artificial rat feeding milk is economic and effective and is applicable to various suckling methods.
Description
technical field [0001] The invention relates to milk products for animal artificial feeding, in particular to an improved aseptic artificial feeding milk for rats. Background technique [0002] Sterile artificial milk refers to the artificial milk used for artificial feeding of newborn rat pups obtained by caesarean section under aseptic conditions. It is difficult to obtain a large amount of rat milk, and it needs to be sterilized to maintain a sterile state. In the past, the high-pressure steam sterilization used in the past caused a serious loss of milk nutrition, and a large amount of lost nutrients needed to be supplemented, which not only increased the cost, but also Affect the nutrient absorption and growth and development of suckling mice. [0003] The inventor of this application had previously applied for the Chinese invention patent CN1742608 (ZL200510060462.3) "artificial feeding of sterile rats". In its formula, the contents of rabbit milk and rat serum are ch...
