Problems solved by technology

At present, the annual productivity of sows in my country is far below the international advanced level, and the pig breeds are also imported from abroad. The actual number of weaned piglets produced by sows is also far behind that of the country of origin, which seriously restricts the development of my country's pig industry.

Embodiment 1

[0030] A method for improving the conception rate of first litter sows, comprising the following steps:

[0031] 1) Breed selection: choose 220-240 day-old sows as gilts, American sows 120-130kg, Danish sows 135-140kg;

[0032] 2) Promoting growth: feeding the gilts with Feed 1;

[0033] 3) Illumination: illuminate the gilts after eating Feed 1 each time;

[0034] 4) Aphrodisiac: After 10 days of feeding with Feed 1, drive the boars with strong sexual desire to the back-up pens to have direct contact with the back-up sows, accurately record the estrus information (estrus date, estrus performance, etc.) Gilts showing signs of heat are relocated;

[0035] 5) Insemination: Start one week before the expected estrous cycle again, place the young boars and gilts with strong sexual desire in the sports pen every day, and let the boars and gilts chase until the gilts show signs of estrus , redness and swelling of the genitals, mucus discharge from the vagina, sluggish expression, e...

Embodiment 2

[0050] A method for improving the conception rate of first litter sows, comprising the following steps:

[0051] 1) Breed selection: choose 220-240 day-old sows as gilts, American sows 120-130kg, Danish sows 135-140kg;

[0052] 2) Promoting growth: feeding the gilts with Feed 1;

[0053] 3) Illumination: illuminate the gilts after eating Feed 1 each time;

[0054] 4) Aphrodisiac: After 13 days of feeding with Feed 1, drive the boars with strong sexual desire to the back-up pens to have direct contact with the back-up sows, accurately record the estrus information (estrus date, estrus performance, etc.) Gilts showing signs of heat are relocated;

[0055] 5) Insemination: Start one week before the expected estrous cycle again, place the young boars and gilts with strong sexual desire in the sports pen every day, and let the boars and gilts chase until the gilts show signs of estrus , redness and swelling of the genitals, mucus discharge from the vagina, sluggish expression, ere...

Embodiment 3

[0070] A method for improving the conception rate of first litter sows, comprising the following steps:

[0071] 1) Breed selection: choose 220-240 day-old sows as gilts, American sows 120-130kg, Danish sows 135-140kg;

[0072] 2) Promoting growth: feeding the gilts with Feed 1;

[0073] 3) Illumination: illuminate the gilts after eating Feed 1 each time;

[0074] 4) Aphrodisiac: After 15 days of feeding with Feed 1, drive the boars with strong sexual desire to the back-up pens to have direct contact with the back-up sows, accurately record the estrus information (estrus date, estrus performance, etc.) Gilts showing signs of heat are relocated;

[0075] 5) Insemination: Start one week before the expected estrous cycle again, place the young boars and gilts with strong sexual desire in the sports pen every day, and let the boars and gilts chase until the gilts show signs of estrus , redness and swelling of the genitals, mucus discharge from the vagina, sluggish expression, e...

Abstract

The invention relates to the field of animal husbandry, in particular to a method of improving the pregnancy rate of a sow. In order to improve the pregnancy rate of the sow, before and after gestation, by adopting different formulas to feed the sow, the quality of the sow's egg cell is improved, therefore, the pregnancy rate of one fetuses of the sow is improved, the pregnancy rate is up to 94%.After gestation, feed 2 is fed to the sow, the nutrients have balanced collocation, the sow growth status is good, the body weight gain and the back fat thickness are increased, the embryo loss is reduced and the health of newborn piglets is improved, so that the number of live births is up to 12-13 head / fetus, and the weight of each newborn piglet is as high as 1.5-1.6 kg.

Description

technical field [0001] The invention relates to the field of animal husbandry, in particular to a method for increasing the conception rate of first-parity sows. Background technique [0002] The reproductive performance of sows determines the production efficiency of the pig industry, and increasing the number of weaned piglets produced by sows can effectively improve the efficiency of pig farming. At present, the annual productivity of sows in my country is far below the international advanced level, and the pig breeds are also imported from abroad. The actual number of weaned piglets produced by sows is also far behind that of the country of origin, which seriously restricts the development of my country's pig industry. The main reasons for the low level of sow productivity in my country include: low level of sow feeding and management, unreasonable nutrient supply at each stage, poor feeding environment and more stress, etc., which directly affect the effective play of s...
