For the current Ovsynch / TAI technology, it mainly focuses on how to synchronize estrus and ovulation, but it cannot control the actual problems of the quality of eggs and embryos formed and the function of the corpus luteum. It provides a method that can improve the conception rate of cows and buffaloes. or method of fecundity

Embodiment 1
[0020] The preparation of inhibin recombinant fusion protein oil emulsion vaccine was prepared according to the method disclosed in Example 1 of patent CN201010618516.4, and the concentration of porcine inhibin recombinant fusion protein in the vaccine was 1-2 mg / mL.
Embodiment 2
[0022] For the immunization and TAI treatment of cows with normal production performance, 89 cows in good body condition were selected and divided into two groups, including 61 cows in the experimental group and 28 cows in the control group.
[0023] Experimental method: On the first day, intramuscular injection of inhibin recombinant fusion protein oil emulsion vaccine to the experimental group, 1ml / head, injection of normal saline, 1ml / head to the control group, and 100μg GnRH injection to all cows at the same time; Cows were injected with 0.3 mg cloprostenol; on the ninth day, all cows were injected with 100 μg GnRH; on the 10th to 11th day, all cows were identified for estrus and artificially inseminated.
[0024] Experimental results: On the 42nd day, the pregnant cows of the experimental group and the control group were diagnosed, and the diagnostic results are shown in Table 1:

Embodiment 3
[0032] The immunization and TAI of female buffaloes were divided into two groups: in summer and autumn, respectively.
[0033] Preparation of female buffaloes: In summer, select 24 Mora-Swamp hybrid female buffaloes aged 5-7 years old and in good condition. Divide the female buffaloes into two groups, 11 in the experimental group and 13 in the control group. head.
[0034] Experimental method: On the first day, the experimental group was injected intramuscularly with statin recombinant fusion protein oil emulsion vaccine 2ml / head, and the control group was injected with normal saline, 2ml / head, and at the same time, all buffaloes were injected with 100μg GnRH; on the seventh day, all buffaloes were injected with 0.3 mg cloprostenol; on the ninth day, all buffaloes were injected with 100 μg GnRH; on the 10th to 11th day, all buffaloes were identified for estrus and artificially inseminated, and on the 42nd day, pregnancy diagnosis was performed;

Abstract
The invention discloses a method for promoting oestrus of cattle and increasing the hybridization conception rate of the cattle. The Ovsynch / TAI technology is adopted in the method. The method is characterized in that a statin recombinant fusion protein oil emulsion vaccine is injected according to the dosage of 1 ml per cattle within five days before or after Ovsynch treatment is carried out on the cattle for the first time. According to the method, statin recombinant fusion protein oil emulsion vaccine immunity and the traditional regular oestrus and regular ovulation technology are combined, so that cows generate statin antibodies, the hypophysis is promoted to secrete FSHs to promote growth of follicles, the ovary is promoted to secrete more activins to promote growth of the follicles and maturity of ova, oestrus of the cows and buffaloes is greatly improved, the hybridization conception rate of the cows and the buffaloes is greatly increased, the frequency of hybridization for pregnancy of the cows is lowered, consumption of manpower and material resources is greatly reduced, the production cost is lowered, the high mortality, caused by reduction of fecundity, of the cows and the buffaloes is decreased, and good economic and social benefits can be achieved.
Description
technical field [0001] The invention relates to the field of animal reproduction, in particular to a method for promoting estrus and ovulation of cattle and improving the conception rate of mating. Background technique [0002] Both dairy cows and buffaloes are important economic species, which are of great significance to the revitalization of my country's dairy industry, agriculture and rural economy. The low fecundity of dairy cows and buffaloes compared to other domestic animals seriously affects the economics of dairy cow and buffalo production. The low fecundity of dairy cows is mainly manifested in the continuous reduction of the breeding conception rate of high-yielding dairy cows and the continuous increase of the number of breedings required for pregnancy. This problem is particularly serious in summer due to high temperature and heat stress. The low fecundity of buffaloes is mainly manifested in late sexual maturity, long parity interval, insignificant estrus per...
