The following terms and definitions apply to this standard:
Estimated breeding value is estimated breeding value, which is a calculation of breeding supply. Indicates the breeding value of the individual as a parent. EHV is a selection tool. For a given trait, there are good breeding partners whose offspring have the most commercial value for that trait, because only half of an individual's EBV will be passed on to its offspring, and a parent has half of its EBV for the quality of its offspring. V is used to estimate the 4 breed characteristics of the species.
The No. 1 white pig is mainly white in color, and is allowed to be small in size; the head size is medium, medium in length, and full in length.
