The invention relates to the technical field of livestock breeding, and discloses a breeding system capable of accurately managing the breeding cycle of sows, which comprises an active piezoelectric platform module, a quasi-static fringe electric field detection array and a multi-mode signal processing unit. The active piezoelectric platform module is located at the bottom of the limiting fence, provides vertical mechanical excitation for the sow and monitors the body weight; the quasi-static fringe electric field detection array is located on the side wall, and a deep penetration non-contact detection electric field is constructed by using an active shielding technology. And the multi-mode signal processing unit cooperatively drives the mechanical excitation signal and the electromagnetic carrier signal, and extracts an intermodulation component synchronous with the mechanical frequency from the feedback of the quasi-static fringe field detection array. And the multi-mode signal processing unit calculates a weighted reproductive response index according to a demodulation result, and judges the reproductive cycle state of the sow by using a double-threshold logic tree. On the basis of the mechanical dielectric intermodulation principle, non-intrusive high signal-to-noise ratio monitoring of the oestrus state of the sow is realized by detecting the mechanical compliance change of biological tissues.

The invention discloses a method for measuring the content of progesterone and testosterone in animal waste. The method comprises the following steps: extracting fresh animal excrement by adopting an ethyl acetate-methyl tert-butyl ether solution, carrying out liquid nitrogen blowing and drying on the extracted animal excrement, adding methanol for dissolving, adding water, and uniformly mixing, so as to obtain a sample extracting solution; carrying out enrichment purification treatment on the sample extracting solution by adopting a combined column strategy of a C18 SPE column and an amino SPE column to obtain a solution to be detected; and detecting the contents of the testosterone and the progesterone in the liquid to be detected by adopting an LC-MS method to obtain the contents of the progesterone and the testosterone in the animal waste. According to the method disclosed by the invention, the solid-phase extraction columns are combined for use, so that effective enrichment and purification of testosterone and progesterone in the excrement sample can be realized, interference matrixes in the excrement sample are efficiently removed, the requirements of an LC-MS method on accurate detection of testosterone and progesterone are met, the result is accurate and reliable, and the method is suitable for large-scale popularization and application. The method has very important practical significance for mastering the reproductive cycle of animals, preventing and treating diseases or managing breeding.

The invention relates to the technical field of aquaculture, and discloses a procambarus clarkii parent feed and a preparation method thereof. According to the procambarus clarkii parent feed provided by the invention, by systematically optimizing the amino acid composition mode of the feed and reconstructing the proportion of key functional amino acids such as methionine, lysine and the like, the precise regulation and control and human intervention on the parent gonad development process are realized, the parent gonad development tends to be synchronous, the parent mature period is concentrated, and the procambarus clarkii parent feed can be used for breeding procambarus clarkii. The technical problems that in a traditional breeding mode, individual development is not synchronous, and the breeding cycle is scattered are effectively solved. After the female juvenile shrimps are fed with the feed for 80 days, the gonad development synchronism is remarkably improved, the follicle proportion, the maturation coefficient and the gonad weight in the maturation period are remarkably increased, the egg carrying rate can reach 95% or above, the single-tail seedling emergence amount exceeds 330, the parent reproductive performance is remarkably improved, and the survival rate of the female juvenile shrimps is remarkably increased. And a stable and high-quality parent guarantee is provided for facility, factory and large-scale artificial breeding of the procambarus clarkii water spray seedlings.

The present application relates to the technical field of livestock breeding regulation, and discloses a natural inducer for promoting the estrus synchronization of cows, a preparation method and application, comprising the following steps: first, collecting natural musk of adult male forest musk deer and uniformly mixing the same to obtain musk raw materials; then, adding the musk raw materials into a solvent to obtain a solid-liquid mixture; then, placing the solid-liquid mixture in an ultrasonic device for ultrasonic extraction, so that the active ingredients in the musk raw materials are dissolved; finally, removing the precipitate and collecting the supernatant to obtain the natural inducer. The chemical signal is transmitted to the hypothalamus through the olfactory pathway, avoiding the pain stress and the risk of inflammation at the injection site caused by muscle injection; at the same time, the reproductive cycle is regulated by activating the neuroendocrine system of the cow itself, rather than directly supplementing exogenous hormones, thereby fundamentally eliminating the hidden danger of exogenous hormone residues in cow's milk or beef, meeting the requirements of modern livestock farming for green and healthy breeding.

This invention discloses an antibody for prolonging ovarian function, a culture medium, a method for inhibiting primordial follicle activation, and its application. The antibody is a CD138 antibody. In the technical solution provided by this invention, the CD138 antibody can precisely regulate the transition rhythm of primordial follicles from a quiescent state to a developing state by targeting and inhibiting the primordial follicle activation signaling pathway. This regulatory mechanism can reduce the ineffective activation and loss of follicles in early reproductive years, allowing more primordial follicles to remain dormant, thereby prolonging the physiological lifespan of the follicle pool. This provides biological protection for the even distribution of reproductive cell resources throughout the reproductive cycle in female individuals, effectively avoiding the risk of infertility or premature ovarian failure caused by premature follicle depletion.
