Abstract

The invention discloses a method for inducing estrus and ovulation of a female cat, and belongs to the technical field of animal artificial propagation. The invention provides the method for inducingestrus synchronization and superovulation of the female cat in order to solve the problem that estrus and ovulation are difficult to synchronize in artificial propagation of the female cat. The methodspecifically comprises the following steps: continuously feeding adult healthy female cats with altrenogest with a dosage of 0.01-20mg / cat / day for 10-20 days, stopping feeding the altrenogest for 2 to 3 days, injecting 10-1000IU of pregnant mare serum hormone into the muscle of the female cat, and intramuscularly injecting 10-1000 IU of human chorionic gonadotropin after 72-96 hours, so that thefemale cat can perform estrus synchronization and superovulation within a preset time. The key technical difficulty of artificial breeding of the domestic cat or the feline is solved.

Description

technical field

[0001] The invention relates to the fields of animal estrus induction, superovulation, artificial insemination and in vitro fertilization, specifically belongs to the field of assisted reproductive technology (ART), and relates to a treatment method for inducing estrus synchronism and superovulation in domestic cats. Background technique

[0002] The estrus synchronization technology uses exogenous hormones to stimulate the ovaries of animals to make a group of animals concentrate on estrus within a certain period of time (24-48 hours).

[0003] From the perspective of ovarian function and morphological changes, the estrous cycle of female animals can be divided into two stages: the follicular phase and the luteal phase. The follicular phase is the stage after periodic corpus luteum degeneration followed by a decrease in the level of progesterone (P4) in the blood. At this time, the follicles rapidly develop and mature in the ovary and finally ovulate. Someti...
