实验用五指山小型猪生长发育测定

目的 对初生至12月龄的实验用五指山小型猪的生长发育进行测定和分析.方法 按常规育种要求的方法,测定普通级实验用五指山小型猪生长发育相关的表型特征,并通过SAS软件进行统计分析.结果 五指山小型猪生长缓慢,体重轻,体型矮小,6月龄体重、体高、体长、胸围、腹围、臀长、管围、胸深、胸宽、臀宽、头长、额宽、颌距、尾长和尾围分别为：12.11±2.99kg、50.93±5.02 cm、32.64±3.81 cm、52.13±5.43 cm、50.64±5.77 cm、58.30±5.88 cm、18.77±2.29 cm、8.51±0.74 cm、16.80±2.09 cm、13.95±1.61 cm、11.95±1.31 cm、17.75±1.47 cm、7.93±0.54 cm、9.74±0.90 cm、14.90±2.40 cm和5.10±0.68 cm.结论 五指山小型猪生长发育稳定,对不同的气候条件有较大的适应性,适合在华南乃至我国广大地区饲养繁育.

Determination of Growth and Development of Outbred Wuzhishan Minipigs

Objective To determine growth and development parameters of outbred Wuzhishan Minipigs （WZSP） from birth to 12 months old. Methods All growth and development parameters were determined according to national and industry standards and statistically analyzed by the SAS soft. Results The growth and development parameters were body weight, body height, body length, chest circumference, abdominal circumference, crown-rump length, ankle circumference, chest depth, chest width, hip width, head length, forehead width, jaw distance, tail length and tail circumference. Results showed that the above parameters of six months old WZSP were 12.11±2.99 kg, 50.93±5.02 cm, 32.64±3.81 cm, 52.13±5.43 cm, 50.64±5.77 cm, 58.30±5.88 cm,18.77±2.29 cm, 8.51±0.74 cm, 16.80±2.09 cm, 13.95±1.61 cm, 1.95±1.31 cm, 17.75±1.47 cm, 7.93±0.54 cm, 9.74±0.90 cm, 14.90±2.40 cm and 5.10±0.68cm respectively. Conclusion The growth and development parameters of WZSP were stable. The WZSP had a greater adaptability on climatic conditions of Guangdong and would be suitable for breeding in Guangzhou as well as southern China region.
