| Abstract: | The experiment of the three- or four-breed crossing for the Wannan Spotted pigs has been studied. It was found that the average daily gain of the Hampshire (medi. Yorkshire-WS), USSR-large white (Landrace(large Yorkshire-WS)), large Y. (Landrace (m. Y. -WS)) and Duroc (1. Y. WS) are 783.1, 750.4, 735.0 and 710.6g, resp., Feed/gain below 3.5 and lean rate above 50%. Especially, the Duroc (I.Y. -WS), lean rate is 59.32% |
