The invention discloses an application, primer pair and kit of a main effect gene of Guizhou black goat multi-lamb. The main effect gene of Guizhou black goat lambing comprises: up-regulated genes AMH, CYP19A1, FOXL2, FSHR, GATA4, INHBA, LHB, LHX9, ZP3, down-regulated genes CNOT1, DMRTA1, GHRHR, Hox-All, Oviductin, PCYT1B, SLC34A2, WDR19, Wnt-7A; the up-regulated genes and down-regulated genes were up-regulated and down-regulated in Guizhou black goats with multiple lambs, respectively. down. Mastering the main genes responsible for lambing performance of Guizhou black goats, and gradually eliminating genetic individuals with single-lamb performance and selecting genetic individuals with multiple lamb performance in the generational breeding process, is of great help in building a new breed of Guizhou black goat specialization with multiple lambs. important scientific basis. The invention has important value for studying the multiple litter traits of Guizhou black goat, and has important significance for improving the production performance, seed supply ability, economic benefit and social benefit of Guizhou local breed sheep. |
