Preparation for controlling ovulation of equus animals and method for controlling ovulation

Abstract

The invention provides a preparation for controlling ovulation of equus animals and a method for controlling ovulation. The preparation comprises a gonadotropin-releasing hormone analogue and a slow release carrier being degradable in bodies of animals. Gonadotropin-releasing hormones are prepared into a slow release preparation, so that the half-life period in bodies can be effectively prolonged,and the preparation can exert the effect of promoting ovulation efficiently and stably for a long time. The preparation disclosed by the invention is injected, 96% or above of female horses and female donkeys can ovulate within 48 hours, and the ovulation time of 96% or above of the animals can be controlled to be within 8 hours, so that efficient ovulation control of the equus animals can be realized, and the breeding pregnancy rate of the equus animals can be notably increased. The ovulation control method is simple to operate, low in cost and notable in control effects, does not cause anyadverse effects on animals and products thereof, can be widely applied to natural mating breeding, artificial insemination, embryo transplanting and timing insemination of the equus animals, and has broad market prospects.

Description

technical field [0001] The invention relates to the field of animal reproduction, in particular to a preparation for controlling ovulation of equine animals and a method for controlling ovulation. Background technique [0002] With the development of the national economy and the improvement of people's living standards, industries such as horse breeding, training, competition and leisure and entertainment have developed rapidly, and the market potential is huge. In recent years, its output value has shown a linear upward trend. It is estimated that by 2030, China's horse industry The total output value will reach trillions. At present, there are about 6 million horses in stock in China, but the quality is uneven, and there is a lack of special speed, endurance performance, equestrian and leisure riding breeds, which cannot meet the current market demand. Therefore, the breeding of characteristic thoroughbred horses is one of the problems to be solved urgently at present. A...

Problems solved by technology

At present, the demand for live donkeys is increasing day by day. The donkey-hide gelatin market alone currently needs 4 million donkey skins per year, while the total stock of donkeys in China is less than 5 million. The supply is in short supply, and we have to rely on foreign imports, resulting in skyrocketing international donkey skin prices.

At present, there are few studies on ovulation control of female donkeys at home and abroad, and the ovulation control methods used for female horses are difficult to apply to female donkeys.
