Effect of GnRH-II on reproductive efficiency and productivity of first parity sows
March 17, 2014By Brett White
Although never investigated, gonadotropin-releasing hormone II (GnRH-II) may be associated with the interaction between nutritional status and reproduction in swine. Therefore, we examined the role...
