Description
Technical Field
The invention relates to a method for promoting a donkey to enter an estrus in advance, in particular to a method for promoting the donkey to enter the estrus in advance by combining illumination and medicaments. Belongs to the technical field of donkey propagation.
Background
The donkey has the characteristics of cold resistance, heat resistance, coarse feeding resistance, strong disease resistance and the like, has wide adaptability, and can normally survive in mountainous areas, plains, plateaus or grasslands. The donkey meat is tender and delicious, has high nutritive value, and is a beautiful name of Tianshanglong meat and overground donkey meat. In the last decade, donkey meat has been sold in markets all over the world, and the price is steadily increasing, which is higher than that of pig, cattle, sheep, horse and chicken. If the processed food is processed into canned donkey meat, sauced donkey meat, steamed donkey meat dumpling, etc., the value can be increased by 2-3 times. The black donkey not only has less feed than other livestock and does not have epidemic diseases, but also has donkey skin which is a raw material for preparing rare medicinal material donkey-hide gelatin, has extremely high economic value and nutritive value, and is very suitable for farmer culture. With the increase of the market demand of donkey-hide gelatin by 30% per year, the domestic donkey stock keeping quantity is decreased by 3.5% per year, and the donkey stock keeping quantity is decreased year by year while the donkey skin gap is larger and larger.
The reason why farmers do not want to raise donkeys is simple, the breeding period of donkeys is longer than that of cattle, and the donkeys can grow at the same speed as sheep. The gestational period of the female donkey is 348-377 days, the average period is about 360 days, most donkey farmers can breed the female donkey after the female donkey has obvious oestrus signs, and the time is at least about half a year. In case of no accident, it takes at least one and a half year to breed one donkey colt. In addition, the donkey colt can grow only in half a year, and donkey farmers can see benefits only in three years. The female donkey is similar to the female horse, so the female donkey can estrate and breed within days after foals are produced, and is easy to be born. The first breeding within half a month after delivery of the donkey is called a blood foal or a heat foal, and the breeding mode can shorten the breeding cycle of the donkey to a certain extent. Although the 'foal' can shorten the donkey breeding cycle, the 'foal' can not be continuously used for a year, otherwise, the available life of the female donkey can be greatly reduced.
The method of the invention adopts illumination and medicine to promote the donkey to enter the estrus in advance, can shorten the breeding cycle of the donkey, does not reduce the utilization period of the donkey, can improve the benefit of donkey farmers and stabilize the market.
