preparation example Construction

[0045] According to one aspect of the present invention, a kind of preparation method of above-mentioned premixing agent, described preparation method comprises:

[0046] Mix fish oil, oatmeal, daylily flowers, quinoa, trichosanthin, and soybean fat phospholipid powder to obtain a premix.

[0047] In some preferred embodiments of the present invention, the preparation method of the premix further includes: firstly pretreating the raw materials, and then weighing and mixing the raw materials according to the dosage ratio of each raw material.

[0048] In a preferred embodiment of the present invention, the preparation method further includes the step of pretreating the raw materials.

[0049] In a preferred embodiment of the present invention, the pretreatment includes the step of drying and pulverizing the oatmeal.

[0050] Preferably, the oatmeal is dried and crushed until 99% passes through a 40-mesh sieve.

[0051] In the above-mentioned preferred embodiment, the pretreat...

Embodiment 1

[0062] Dried and pulverized oatmeal; dried and pulverized quinoa, dried and pulverized daylilies;

[0063]Then, according to 5 parts of fish oil, 10 parts of oatmeal, 5 parts of daylily flower, 8 parts of quinoa, 5 parts of trichosanthin, and 67 parts of soybean fat phospholipid powder, weigh appropriate amount of each raw material respectively;

[0064] Then, the above raw materials were mixed to obtain the premix of Example 1.

[0065] The premix obtained in Example 1 was added to the basic feed at a mass ratio of 4 wt%, to obtain the pig feed of Example 1.

Embodiment 2

[0067] Oatmeal, quinoa, and Hemerocallis flowers are processed according to the method of Example 1;

[0068] Then, according to 6 parts of fish oil, 15 parts of oatmeal, 6 parts of daylily flower, 12 parts of quinoa, 8 parts of trichosanthin, and 53 parts of soybean fat phospholipid powder, weigh appropriate amount of each raw material respectively;

[0069] Then, the above raw materials were mixed to obtain the premix of Example 2.

[0070] The premix obtained in Example 2 was added to the basic feed at a mass ratio of 3.5 wt%, to obtain the pig feed of Example 2.

Abstract

The invention provides a premix for shortening oestrus interval time of sows and a preparation method and application thereof, and relates to the technical field of feed additives. The premix for shortening the oestrus interval time of sows is used by combining the following raw materials: fish oil, oatmeal, hemerocallis fulva flowers, quinoa, trichosanthes roots and soybean fatty phospholipid, isused as a feed additive for weaned sows, and can effectively shorten the oestrus interval time of the sows and improve the reproductive performance of the sows.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a premix for shortening the estrus interval of sows, a preparation method and application thereof. Background technique [0002] Pork is the main source of meat in people's lives. As the demand for pork increases year by year, the production demand for live pigs is also gradually increasing. The level of reproductive performance of sows will directly affect the number of piglets provided by sows each year, which in turn will affect the supply of live pigs and pork. [0003] There are many indicators used to measure the reproductive performance of sows, among which the estrus interval (that is, the time interval between weaning and re-breeding of sows) is an important indicator of reproductive performance. Generally speaking, the average time from weaning to re-breeding of sows is within 10 days. According to the time of sows from weaning to re-breeding, pregnancy and lact...
