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 lar

Example Embodiment

[0024] Example 1:

[0025] A method of aphrodisiac for sows during the mating period, according to the following steps:

[0026] 1) Use 49-51℃ warm water to clean the body surface and vulva of the sow every morning from 9:00 to 10:00, dry it after washing, and use an insemination device to inject 30-40mL of sows into the sow's uterus every day. Aphrodisiac used;

[0027] 2) Feeding: small groups, feeding the early stages of pregnancy, feeding 1.6-1.8kg per head per day, feeding 3 times a day, feeding 1 / 2 of the total daily feed from 10:00-11:00, 17:00-18:00 feeding 1 / 3 of the total daily feed volume, 21:00-22:00 feeding 1 / 6 of the total daily feed volume;

[0028] The aphrodisiac used by sows during the mating period is obtained by the following preparation method:

[0029] (1) Raw material processing: the fresh immature mangosteen and the fallen mangosteen are polished to remove the fluff on the surface of the mangosteen;

[0030] (2) Subcritical water extraction: crush the raw materi...

Example Embodiment

[0046] Experimental example:

[0047] The aphrodisiac used by the sows in the mating period of the present invention was tested in the pig farm of our company. The feed (weight percentage): corn 30%, soybean meal 25%, fish meal 25%, bran 13%, brown sugar 4%, Vegetable oil 2%, multivitamin 1%.

[0048]

[0049]

[0050] Conclusion: Adopting the aphrodisiac used by sows during the mating period of the present invention can effectively increase the estrus rate of sows before mating, increase the average number of litters alive and the average birth weight of piglets, and at the same time, can effectively prevent vaginitis in pigs.

[0051] In the early stage of the present invention, a comparative experiment was conducted on the subcritical water extraction of immature Luo Han Guo. Using the temperature range of 130-140°C, the effect is still lower than that of the temperature range of 120-150°C. The analysis is because the temperature range is wide and the extraction More substances a...

Abstract

The invention discloses an estrualization method for a sow in a mating period. The estrualization method is performed according to the following steps: 1) cleaning the body surface and vagina of the sow by using 49-51 DEG C warm water at 9:00-10:00 in the morning every day, wiping the body surface and vagina of the sow after cleaning, and inputting 30-40mL of aphrodisiac used by the sow in the mating period into the uterus of the sow by using an inseminating syringe every day; and 2) feeding, namely carrying out small group captivity, feeding each sow with an early pregnancy material three times every day according to the feeding quantity of 1.6-1.8kg, wherein the material fed at 10:00-11:00 accounts for 1/2 of total feed amount per day, the material fed at 17:00-18:00 accounts for 1/3 oftotal feed amount per day, and the material fed at 21:00-22:00 accounts for 1/6 of total feed amount per day.

Description

technical field [0001] The invention belongs to the technical field of pig breeding, and in particular relates to a method for aphrodisiac of sows in 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), whic...
