Goat prolificacy regulation method

Abstract

The invention discloses a goat prolificacy regulation method. The method is characterized by selecting female goats to be put in PG vaginal suppository, injecting 50IU-70IU FSH (Follicle-Stimulating Hormone) in gradient by four times for (50IU: 20IU, 10IU, 10IU, 10IU; 70IU: 30IU; 15IU, 15IU, 10IU) from the 9th day to the 11th day after the suppository is putted in, then injecting FSH once every 12hours, injecting 10IU LH (luteinizing hormone) after the last suppository is removed, testing estrus once every 12 hours, injecting 50IU-80IU LH to each female goat after estrus, and performing breeding by increasing the amount of insemination by 3-4 times in case of artificial Insemination. The method has the advantages that dosage of FSH is controlled based on the technology of goat superovulation, and the number of follicle development is controlled so as to realize goat prolificacy; by the aid of the method, each female goat can have 2-4 kids, goat reproductive capacity is improved rapidly, and breeding process is shortened.

Description

Technical field: [0001] The invention relates to the technical field of animal husbandry reproduction, in particular to a method for regulating goat multiple lambs. Background technique: [0002] Goats are single-born animals, and very few goat breeds have multiple births. However, reproduction is the main economic trait that determines the output of large-scale breeding, especially in singleton animals with few litters, ewe reproductive benefits account for a larger proportion of the total benefits. However, low heritability of reproductive traits, long cycle, slow progress in breeding, and complex relationship with growth traits are the main reasons restricting the economic benefits of raising goats. Therefore, the development of new technologies to improve fecundity has important theoretical and practical significance for the rapid improvement and improvement of goat reproductive performance. [0003] Superovulation technology and embryo transfer technology are more com...

Problems solved by technology

First of all, embryos are easily lost in the process of embryo punching in this technology, which has high requirements for the proficiency of the operator; moreover, the embryos punched out need to be picked out under a microscope and high-quality embryos are selected, which is also likely to cause embryo loss Or artificially miss high-quality embryos; finally, the liquid during the transfer process can easily cause embryo loss, or the transfer is not in place, resulting in transfer failure and failure to conceive

In addition, this technology requires a large number of recipient sheep, and the workload is extremely high, and it is extremely demanding to master the technology of estrus synchronization in sheep
