摘要
对59头后备藏猪进行生长发育性能测定,结果表明:公、母全程日增重分别为160.63,192.15 g;全程料肉比分别为3.59、3.32。藏猪与梅山猪杂交后,可明显改善其生长发育性能,其6月龄体重分别较藏公猪、藏母猪提高91%与65%,日增重分别提高107%与73%。本次测定基本探明了藏猪的初配年龄和适宜体重:公猪5月龄、母猪6月龄,体重为30 kg左右。
The growth and development performance of 59 Tibetan reserve swine were tested and results showed that boar average daily weight gain of the boar and sow in whole period was 160.63 g and 192.5 g, and the feed conversion ratio of the bear and sow in whole period was 3.59 and 3.32 ,respectively. The Tibetan -Meishan crossbreed had better growth performance compared with the pure Tibetan pig,their body weight at age of 6 month was 91% and 65 % higher than the Tibetan boar and sow, and the average daily weight gain was 107 % and 73 % higher than the Tibetan boar and sow. This results suggested that the first-mating age of the Tibetan pig was 5-month age for boar and 6- month age for sow, and the suitable mating-weight was 30 kg around.
