Embodiment 1

[0018] In a 100ml spray bottle, add 3mg of androst-16-en-3-one, 69g of ethanol, and 30g of water, and mix for use. 142 sows weaned on the same day were selected and randomly divided into experimental group and control group according to gestational age and body fat. The experimental group used sow aphrodisiac preparations in the morning and afternoon, and the control group was used in the morning and afternoon. Use boars to induce estrus, so that the two groups of limit pens are separated by a certain distance without interfering with each other; a total of 50 days, 62 estrus in the experimental group, 87% estrus, and 58 estrus in the control group, 82% estrus. The estrus rate of the experimental group is higher; the estrus conception rate of artificial insemination after estrus, the conception rate of 62 in the experimental group is 97%, and the conception rate of 58 in the control group is 98%.

Embodiment 2

[0020] In a 100ml spray bottle, add 3mg of androst-16-en-3α-alcohol, 69g ethanol, 30g water, and mix for use. 148 sows weaned on the same day were selected and randomly divided into experimental group and control group according to gestational age and body fat. The experimental group used sow aphrodisiac preparations in the morning and afternoon, and the control group was used in the morning and afternoon. Using boars to induce estrus, so that the two groups of stalls are separated by a certain distance without interfering with each other; a total of 60 days, the result of the experimental group is 68 estrus, the estrus rate is 91%, and the control group is 70 estrus, the estrus rate is 93%. The estrus rate of the experimental group is higher; the estrus conception rate of artificial insemination after estrus, the conception rate of 68 animals in the experimental group is 88%, and the conception rate of 70 animals in the control group is 93%.

Embodiment 3

[0022] Add 2 mg of androst-16-en-3-one, 56 g of ethanol, 40 g of water, and 3 g of dimethyl sulfoxide to a 100 ml spray bottle, and mix for use.

Abstract

The invention relates to a hormone spray agent for sow aphrodisiac, which comprises the following components in percentage by weight: 0.001-0.006% of swine ectohormone, 0-5% of cosolvent and balance of a water solution containing 55-85% of ethanol, wherein the swine ectohormone is androst-16-ene-3 alpha-ol or androst-16-ene-3-one. The spray agent of the invention has simple manufacturing, can effectively improve the reproductive capacity of a sow, and promotes the development of livestock breeding.

Description

Technical field [0001] The invention relates to a sow aphrodisiac hormone spray, which is an aqueous solution containing 0.001-0.006% by weight of porcine exohormone, 0-5% by weight of cosolvent, and the rest is an aqueous solution containing 55-85% of ethanol. The spray is simple to make, safe and convenient to transport and use, and low in cost. It can effectively promote sows to estrus, improve the reproductive capacity of sows, and promote the development of the breeding industry. technical background [0002] In the past, the pig industry in my country relied to a large extent on the backward methods of farm households, which could easily lead to tight pork supply and price increases. Therefore, we need to establish intensive and large-scale pig breeding bases. The efficiency of intensive pig raising depends on the reproductive ability of the sow. That is, the number of litters per sow and the number of litters per litter. The annual number of litters per sow and the number...
