合作猪在舍饲条件下的行为特征观察

Study on Behaviour Characteristics of Hezuo Pig under Condition of Barn Feeding

观察舍饲条件下合作猪的行为特征，表明：在1d内，公猪走动时间占30％～40％，卧息时间占60％～70％，母猪走动时间占15％～25％，卧息时间占75％～85％，1d内采食时间占4％左右，排粪5～6次。合作母猪性成熟早，发情特征明显。青年公猪40～55日龄出现爬跨行为，80日龄可参加配种。母猪产前18h开始闹圈，产仔持续时间1．5～4．5h。母猪哺乳能力强。合作猪经调圈或合群后产生咬斗行为，以便建立新的位次序列。合作猪抗逆性强，耐粗饲，对高原环境有独特的适应能力。

Behaviour characteristics of Hezuo Pig under condition of barn feeding were studied and observed. The results showed that in a day, the boars＇ walking time accounted for 30%-40%, their rest time accounted for 60%-70%; foraging time accounted for 4% approximately, the pigs defecated for 5-6times in one day. The sows sex maturity period was earlier and their oestrus symptom was obvious. Youth boar appeared sexal action in 40-55 days old and mated at the age of 80 days old. The sows appeared serious boring--earlier stage action before 18 hours. The bearing period asted for 1.5-4.5 hours. The sows had high nursing performance. In order to establish new order relationship, Hezuo Pig usually fought within herd after being adjusted to new pigsty. Coarse food grain is palatable for Hezuo Pig. The pigs adapted to plateau condition.
