Abstract

The invention belongs to the technical field of cross breeding, and particularly relates to a breeding method for high-quality Luchuan pigs. South Yunnan small-ear boars and local Luchuan pigs are selected to be mated so that F1 generation breeding boars can be generated, large white sows and local Luchuan pigs are selected to be mated so that F1 generation breeding sows can be generated, the F1 generation breeding boars and the F1 generation breeding sows are matched, and produced and bred F2 generation piglets are the high-quality Luchuan pigs. The bred high-quality Luchuan pigs overcome thedefects that the local Luchuan pigs are short and small in body, excessively concaved in back and waist, slow in growth speed, low in dressing percentage, lean meat percentage, feed conversion ratioand number of broods of piglets produced by the sows and the like; the high-quality Luchuan pigs are resistant to temperature and more suitable for being bred in the Guangxi region; specially-made feedstuff is used for breeding the F1 generation breeding boars, the F1 generation breeding sows and the F2 generation piglets, can supply sufficient nutrient substances for the F1 generation breeding boars, the F1 generation breeding sows and the F2 generation piglets, and can also increase the survival rate of the piglets.
