| 摘 要： | 岔路猪在气候条件较差的冬季和夏季，其生理指标(体温、呼吸次数、脉搏)均为正常值；6月龄体重57.23±4.5kg、第2～3次发情期持续时间为50.88±7.97h。大杜岔和杜岔杂交组合产仔数分别为14.88和14.25头，与岔路猪相近(p>0.05)，60日龄窝重表现了明显的杂种优势。大杜岔杂交组合日增重(708.3g)、料重比(2.72)和瘦肉率(57.85%)均明显高于杜岔杂交组合，有推广价值。

Study on the Adaptability and the Pattens of Crossbreeding in the Ca Lu Pigs |
| |
| Abstract: | The physilogical index (body temperature, respiration rate, pulse) was normal under the poor climate conditions in winter and summer; body weight at 6 month old is 57.23±4.5 kg, and the estrous duration fram first estrous to the third was 50.88±7.97 hours. Litter size in Large Yorkshire×Duroc×Ca Lu pig (L×D×C) and Duroc×Ca Lu pig (D×C) were 14.88 and 14.25 respectively, and those were near the size of Ca Lu pig. Litter weight at 60 days old showed a significant crossbreeding superiority. Daily gain (708.3 grams), ratio of feed intake/weight gain (2.72) and the rate of lean (57.85%) in L×D×C were obviously higher than those in D×C, which was of value and should be popularized. |
