0
()
摘要:
在二元杂交研究基础上,选择其中较好组合大约克×皖南花(大花)和中约克×皖南花猪(中花)杂交一代母猪进一步和汉普夏、苏长(苏白×长白猪)、大长(大约克×长白猪)、杜洛克公猪作多元杂交试验研究,研究结果:体重20~90千克,平均日增重:汉、中花783.10克,苏长、大花750.46克,大长、中花734.98克,杜、大花710.62克;饲料转化效率全都在3.5以内;瘦肉率在50%以上;其中杜大花胴体瘦肉率达到59.32%,且肉色和大理石纹均优。

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%
Key words:  Wannan spotted pigs, Four-breed crossing.
