Method for improving female lamb rate of offspring of milk goats
The method comprises the following steps: firstly, determining specifically expressed protein DPY30 in Y sperms of the milk goats, then packaging goat DPY30 gene interference lentivirus, injecting the goat DPY30 gene interference lentivirus into testis of a stud ram, collecting semen of the stud ram...

| description | The method comprises the following steps: firstly, determining specifically expressed protein DPY30 in Y sperms of the milk goats, then packaging goat DPY30 gene interference lentivirus, injecting the goat DPY30 gene interference lentivirus into testis of a stud ram, collecting semen of the stud ram after 47d, identifying the semen quality and the proportion of the X sperms and the Y sperms in upstream sperms, and determining the female lamb rate of the offspring of the milk goats according to the semen quality and the proportion of the X sperms and the Y sperms. After artificial insemination with the semen of the breeding ram injected with the DPY30 gene interference lentivirus, the female lamb rate reaches 58.20% and is increased by 22.08%, and the number of born female lambs is remarkably increased. The interference lentivirus is adopted to regulate and control expression of the gene DPY30 of the specific expression protein in the Y sperm of the coded milk goat in the goat testis, the female lambing rate o |
