It is to be understood that the specific embodiments are not intended to limit the invention to the specific embodiments, but are to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the following description of the present invention, detailed description of known related arts will be omitted when it is determined that the gist of the present invention may be unnecessarily obscured.

In the following description, the same reference numerals are used for similar parts throughout the specification.

Mammal piglets are calibrated by milk component and flow rate (the amount of enemy) of sows and are closely related to wet feed of these sows.

In addition, weights of milk sows and feed sows should be different for each feeding rate and water supply level by the feeding stage. Unlike normal pigs, it is important to provide accurate feeds or supply appropriate number of feeds to each sows.

In the specification for describing the present invention, a sow sow is defined as a concept that includes both sowing money and sows feeding a young.

In the pregnancy phase, the feed intake should be reduced to prevent obesity, but in sows with labor or calves, milking should be given to the offspring so the feed intake should be increased.

Generally improved sows produce a flow rate of 12-15 liters / day.

Table 1 analyzes the components of breast milk and normal oil.

beestings(%) Normal oil (%) moisture 70.0 80.0 protein 20.0 5.5 Fat 7.0 9.0 Ash 0.5 0.5 Lactose 2.5 5.0

* whittmore, 1993

As shown in Table 1, the moisture content of colostrum is changed from 70% to 80%, and the protein is reduced to 20% in colostrum and 5.5% in normal oil.

In addition, Table 1 shows that there was a difference in the components of colostrum and normal oil immediately after delivery and that the sows maintained the average oil quality of the normal sows, And the food should be controlled.

For example, in case of normal sows breeding after delivery, it is preferable to gradually increase the first day from 2.0 kg to 6 kg on the first day, from 6 to 8 kg on the second, and from 8 to 9 kg on the third month .

Also, it is desirable to reduce the feed from 2 kg to 0.5 kg in order to induce comfortable labor before delivery and adjust to feed control in the first week.

For this purpose, the feed amount and the intake amount should be controlled for each sow, and the sow quantity should be adjusted individually for each sow.

In this way, adjusting the feed rate individually may increase the weight of the piglet for reasons of increased milking ability.

Considering that the moisture content of milk is 70 ~ 80%, the control of the sow sowing is as important as that of the sowing quantity management. Healthy piglets can be managed.
