Embodiment 1

[0024] A feed additive for sows in early pregnancy, obtained by the following preparation method:

[0025] 1) Raw material processing: grind fresh immature Luo Han Guo and fallen Luo Han Guo to remove the fluff on the surface of Luo Han Guo, and then add 1 / 5 weight of fresh Luo Han Guo stems and leaves;

[0026] 2) Subcritical water extraction: crush the raw materials obtained in the previous step until the particle size is less than 0.5mm, add deionized water of equal weight, and perform subcritical water extraction. The extraction temperature is 120-160°C and the pressure is 5-8MPa. The extraction time is 10-15min. After the extraction is completed, release the pressure and collect the extract;

[0027] 3) Concentration: Concentrate the extract obtained in the previous step into a thick paste with a relative density of 1.10-1.15 at 70°C to obtain.

Embodiment 2

[0029] A feed additive for sows in early pregnancy, obtained by the following preparation method:

[0030] 1) Raw material processing: wipe fresh immature Luo Han Guo and fallen Luo Han Guo to remove the fluff on the surface of Luo Han Guo, and then add 1 / 4 weight of fresh Luo Han Guo stems and leaves;

[0031] 2) Subcritical water extraction: crush the raw materials obtained in the previous step until the particle size is less than 0.5mm, add deionized water of equal weight, and perform subcritical water extraction. The extraction temperature is 120-160°C and the pressure is 5-8MPa. The extraction time is 10-15min. After the extraction is completed, release the pressure and collect the extract;

[0032] 3) Concentration: Concentrate the extract obtained in the previous step into a thick paste with a relative density of 1.10-1.15 at 70°C to obtain.

Abstract

The invention discloses a feed additive for sows at an early pregnancy period. The feed additive is prepared by the preparation method comprising the following steps of (1) treating raw materials: removing fine hair on the surfaces of fresh immature fructus momordicae and falling fructus momordicae, then adding fresh fructus momordicae stems and leaves, of which the weight is one fifth to one fourth of that of the fructus momordicae without the fine hair to obtain materials; (2) performing subcritical water extraction: breaking the materials obtained in step (1), adding deionized water of which the weight is the same as that of the materials, performing subcritical water extraction, wherein the extraction temperature is 120-160 DEG C, the pressure is 5-8MPa, and the extraction time is 10-15min, ending the extraction, performing pressure relief, and collecting extract liquid; and (3) performing concentration: concentrating the extraction liquid obtained in the step (2) to thick paste ofwhich the relative density is 1.10-1.15 at 70 DEG C, so that the feed additive is obtained.

Description

technical field [0001] The invention belongs to the technical field of pig feed, in particular to a feed additive for sows in early pregnancy. Background technique [0002] With the continuous improvement of pig breeding technology, the pig breeding structure is rapidly developing towards a large-scale, intensive and professional farming model. Among them, litter size is an important indicator to measure the reproductive performance of sows, and increasing the litter size of the first litter of sows will help improve the lifelong reproductive performance of sows. [0003] The purpose of raising sows and improving the annual productivity of sows is that a sow can provide more healthy piglets a year. Usually, it mainly starts from the following three aspects: 1. Take effective measures to shorten the lactation period of sows and the interval between weaning and re-breeding of sows; 2. Increase the number of live litters of sows; 3. Improve the survival rate of piglets . [...
