Embodiment approach

[0053] 1. The ewes injected with twin seedlings must be healthy and disease-free, have normal reproductive ability, have a large physique, and have a medium-to-medium body condition. It is best to be multiparous ewes, and the best age is 3 to 5 years old.

[0054] 2. Male and ewe sheep should be reared separately one month before and during the use of twin seedlings.

[0055] 3. The storage temperature of twin seedlings should be kept between 0°C and 8°C, the transportation time should be as short as possible, the temperature should not exceed 30°C, and it is best to store them in a refrigerator at 4°C, and the shelf life is two years.

[0056] 4. The injection site is subcutaneous in the neck. A total of two immunization injections, 1ml each time, the first injection 42 days before breeding, the second injection after 21 days, and the breeding can be done after another 21 days, either by hand or artificial insemination. The mating period can be 2 months.

Abstract

The invention discloses a production process of a sheep and goat steroid hormone antigen twins vaccine, and the production process comprises the following steps of; (1) synthesizing carboxymethyl hydroxylamine hydrochloride; (2) synthesizing a testosterone antigen; and (3) adding an adjuvant. The production process disclosed by the invention can be used for obviously enhancing the lambing rate of sheep within 30% generally by about 20% averagely, can induce the twinning by starting the in-vivo intrinsic breeding potential of an ewe through immunity effect, is coordinated with the normal breeding physiological function of gestation and lambing in a natural state without causing adverse effect on the later production property of the ewe and is easy and convenient to apply and easy to operate in production; and according to the invention, a farmer and herdsmen technicist can complete the operation by only needing an injector without a specialized technicist or specific equipment appliance.

Description

technical field [0001] The invention belongs to the technical field of breeding and immunization of animal husbandry, and relates to a production process of twin seedlings of sheep and goat steroid hormone antigens. Background technique [0002] The number of sheep and goats in my country has exceeded 300 million, ranking first in the world in terms of quantity, but only 0.2 per capita. The slaughter rate of sheep in my country has reached more than 50%, which is basically close to the developed countries of animal husbandry. However, because the absolute amount per capita is too low, the per capita mutton consumption is also lower than the world average, with an average of less than 3 kg per person. With the rapid development of our country's economy, the national income has risen sharply, and people's consumption demand has also increased day by day, changing from food and clothing in the past to the pursuit of nutrition. Because lamb meat has the advantages of tenderness...
