“…The meat-type goat breed has the excellent characteristics of heat resistance (Wang et al, 2014a), in recent years, with the increase in farm size and the number of goats bred, the low farrowing rate and milkability have exerted increasing influence on the scale of Hainan black goat. There were a few reports on the genetic diversity (Zhou et al, 2012), inflammasome components (Zhang et al, 2017) and nutrition regulation methods (Wang et al, 2014b;Wang et al, 2017;Wang et al, 2015b) of Hainan black goat, however, so far, there still no report on the reproductive law of this specific goat species, the study was the first research on the reproduction characteristics of Hainan black goat, we aimed to improve the fertility of this species through uncovering the internal rule of the changing of serum proteins during the whole reproductive cycle.…”
