Abstract

The invention discloses a method for synchronizing oestrus of Nubian goats, which comprises the following steps of manufacturing artificial corpus luteum, combining the artificial corpus luteum with corpus luteum in vivo to inhibit the follicular development of an ewe, eliminating the artificial corpus luteum by removing a suppository, and injecting the cloprostenol with a specific dosage to dissolve the corpus luteum in vivo to promote the development, maturation and ovulation of the follicle. According to the method for synchronizing oestrus of the Nubian goats, the estrus, mating, pregnancyand delivery of the animal population are adjusted to be carried out simultaneously within a certain time, the industrialized and assembly line management cultivation of the lactation period, the reserve period and the fattening period is unified, and the scientific feeding management of the descendants is well carried out. The method for synchronizing oestrus of the Nubian goats aims to fill inthe blank in the prior art for treating the synchronous oestrus of the Nubian goats, and provides a set of concrete implementation method, medicament and dosage of the technology for treating the synchronous oestrus of the Nubian goats.

Description

technical field [0001] The invention relates to the technical field of animal husbandry, in particular to a method for simultaneous estrus of Nubian goats. Background technique [0002] Simultaneous estrus, also known as synchronous estrus, is to use certain hormone preparations to artificially control and adjust the process of a group of female animals' estrus cycle, so that they can concentrate on estrus within a predetermined time. Its principle is: in one estrous cycle of female animals, the luteal phase accounts for about 70% of the length of the entire estrous cycle (such as the luteal phase of sheep is 15 days), and the progesterone secreted by the corpus luteum has a strong inhibitory effect on the development and maturation of follicles. After the corpus luteum subsides, the progesterone hormone content decreases, and the follicles can develop and mature until ovulation, and the female animal can express estrus. Therefore, controlling the growth and decline of the ...
