Problems solved by technology

The Ovsynch-TAI estrus synchronization program has been widely used in livestock breeding, but the effect of estrus synchronization in summer is not ideal. It is manifested in a significant decrease in the conception rate during the summer estrus period and an increase in early embryo mortality, mainly due to heat stress. Blood circulates on the body surface, resulting in insufficient blood supply to the digestive, reproductive, and lactation systems, which in turn affects digestion, reproduction, and lactation, and greatly reduces milk production. How to effectively improve the reproductive rate of dairy cows in summer and milk production and quality is an urgent need to solve technical issues

Embodiment 1

[0034] In this experiment, by adding 1-4 mg capsaicin per kilogram of TMR to postpartum dairy cows, the effect of capsaicin on follicle development, estrus rate and conception rate, lactation and blood biochemical indexes of dairy cows was studied, so as to improve the pregnancy rate of dairy cattle in summer breeding, and at the same time improve dairy cows. milk production. Select 101 healthy pre-perinatal dairy cows in good body condition, select cows on the 20th day after giving birth (the day of delivery is recorded as 0 days), and divide them into 4 groups (pay attention to indicators such as weight, age, parity, milk production, etc. in each group). balanced distribution), and were fed diets supplemented with 0, 2, 4, and 6 mg of capsaicin per kg of TMR for one month (30 days). Experiment group I started from 20 days postpartum, adding 2 mg capsaicin per kilogram of TMR, and fed continuously for 30 days from postpartum 20 days to postpartum 50 days; group II started fro...

Embodiment 2

[0066] A treatment method for adding capsaicin into the diet to improve the reproductive rate, milk production and quality of dairy cows in summer. To select healthy dairy cows without reproductive tract diseases, the process can be as follows: figure 1 The specific scheme is as follows:

[0067] The cows on the 20th day after parturition (day 0 of parturition) were selected, and 1-4 mg capsaicin was added to the diet per kilogram of TMR, and they were fed for one month (30 days).

[0068] Day 0: On postpartum day 50 (week 1), the first intramuscular injection of GnRH at a dose of 200 μg / head on Monday at 15:00 pm to one or more healthy cows in the estrus cycle to induce estrus .

[0069] Day 6: On the 56th day postpartum, B-ultrasound examination was performed from the 6th day of estrus (the day before PGF2ɑ injection) to the 12th day of ovulation (that is, 72h after GnRH injection), and the follicle development, estrus and ovulation status were recorded.

[0070] Day 7: On...

Abstract

The present invention provides a treatment method for improving the reproductive rate and milk yield of dairy cows in summer by using capsaicin, which comprises the following steps: S1, selecting the dairy cows on the 20th day after delivery, adding capsaicin to the diet, and feeding them continuously for one month; S2. The 50th day after the cows were recorded as the 0th day of simultaneous estrus treatment of dairy cows, and gonadotropin-releasing hormone was injected intramuscularly into healthy dairy cows in the estrus cycle; S3, on the seventh day, PGF2ɑ was injected intramuscularly; S4, on the ninth day, the first day Second injection of gonadotropin-releasing hormone and mifepristone to promote ovulation; S5, artificial insemination on the 10th day; S6, 15th day, intramuscular injection of human chorionic chorionic stimulation on the 5th day after artificial insemination gonadal hormones. The invention can effectively improve the estrus rate, mating rate and conception rate of postpartum dairy cows at the same time, increase the milk production of dairy cows, and improve milk components; there is no need for estrus detection, timing insemination, and convenient operation.

Description

technical field [0001] The invention belongs to the technical field of reproduction of dairy cows in animal husbandry, and particularly relates to a treatment method for using capsaicin to improve the reproduction rate and milk production of dairy cows in summer. Background technique [0002] Although dairy cows are domestic animals in heat all year round, their reproductive performance is easily affected by factors such as environment and climate. Summer heat stress can lead to decreased feed intake, decreased appetite, and imbalance of energy supply and demand, affecting reproductive performance. Dairy cows, especially high-yielding dairy cows, encounter heat stress during the peak postpartum lactation period, which can easily lead to increased incidence of reproductive disorders, such as abnormal estrus, quiet estrus, delayed ovulation, and reproductive tract inflammation, and will lead to increased early embryo mortality. , the proportion of repeatedly mated infertile c...
