Problems solved by technology

[0003] At present, when sows in pig farms are mating, due to reasons such as poor estrus of weaned sows or unreasonable mating methods, etc., the first mating or re-mating of multiparous sows is unsuccessful, and the proportion of sows that have been empty for a long time If the proportion is large, the feeding cost will increase, and there will be a large economic loss. In addition, due to the inability to breed in time, the pig farm's litter rate will be greatly affected, and it will be difficult to improve the economic benefits, which is not conducive to the development of the pig farm.

Embodiment 1

[0022] The aphrodisiac used by sows in the mating period is obtained by the following preparation method:

[0023] 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;

[0024] 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 120-150°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;

[0025] 3) Filtration: filter the extract obtained in the above step through 0.45 μm, seal and store, to obtain.

Embodiment 2

[0027] The aphrodisiac used by sows in the mating period is obtained by the following preparation method:

[0028] 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;

[0029] 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 120-150°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;

[0030] 3) Filtration: filter the extract obtained in the above step through 0.45 μm, seal and store, to obtain.

experiment example

[0038] The aphrodisiac used by sows in mating period of the present invention is carried out feeding test respectively in the pig farm of the company, feed (percentage by weight): 30% of corn, 25% of soybean meal, 25% of fish meal, 13% of bran, 4% of brown sugar, Vegetable oil 2%, multivitamin 1%.

[0039]

[0040] Conclusion: the aphrodisiac used for sows during mating period of the present invention can effectively increase the estrus rate of sows before mating, increase the average number of live piglets and the average birth weight of piglets, and at the same time, can effectively prevent vaginitis in pigs.

[0041] In the early stage of the present invention, a comparative experiment was done on the subcritical water extraction of immature Luo Han Guo. Using the temperature range of 130-140°C, there is still a gap in the effect compared with the temperature range of 120-150°C. The reason for the analysis is that the temperature range is wide. More substances come out, ...

Abstract

The invention discloses an aphrodisiac for sows in a breeding period. The aphrodisiac is obtained by a preparation method comprises the following steps: 1) raw material processing: taking fresh immature and fallen siraitia grosvenorii fruits, removing villi on surfaces of the siraitia grosvenorii fruits, adding 1 / 5-1 / 4 by weight of fresh siraitia grosvenorii stems and leaves; 2) subcritical waterextraction: crushing the raw materials obtained in the step 1, adding equivalent deionized water, extracting subcritical water at 120-150 DEG C under a pressure of 5-8 MPa for 10-15 min, finishing extraction, relieving pressure, and collecting extract; 3) filtration: filtering the extract obtained in the step 2 through 0.45 [mu]m, sealing and storing to obtain the aphrodisiac.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and in particular relates to an aphrodisiac for sows in the mating period. Background technique [0002] Sow mating, the goal of the mating room is to use healthy mating boars to mating sows in good condition to increase the conception rate, and the daily management of weaned sows should focus on estrus stimulation. After weaning, the breasts swell due to milk production, and when milk production and reabsorption are in balance, the lactation process gradually ceases. After 2-3 days of weaning, breast swelling decreases, cellulite begins to decompose, and FSH (follicle-stimulating hormone) stimulates oocytes to develop into follicles, and the ovarian follicle ligament will increase rapidly and begin to secrete estrogen in order to receive fertilized eggs for the uterus To prepare and stimulate the symptoms of estrus, estrogen will promote the secretion of LH (luteinizing hormone), which can...
