摘要
为了比较广东大花白猪和蓝塘猪与大白、长白猪的哺乳期行为差异，分别选产后5-15d、带仔数为8～11头的5头土母猪与5头洋母猪，连续5d观察其在产仔限位栏内的行为表现。着重观察了母猪哺乳行为的引起、哺乳过程特征、母性行为、规癖行为和采食行为；研究结果表明，土母猪母性行为强、哺乳次数多4—5次、护仔性强，采食力不如洋母猪，小猪寄养换窝干扰母猪正常母性行为和哺乳。在此基础上讨论了土母猪和洋母猪对周围环境变化反应的敏感性。
The study focused on identifying the behavior difference between Guangdong Dahuabai, Langtang pig and Largewhite and Landrace. Each five lactating sows from four species, with nursing 8-11 piglets aged 5-15 days per sow, were appointed for the observation in their locations. Continued 5 days, the observation covered the reasons leading nursing, the whole nursing process, maternal behavior, intaking behavior and stereotype of the above four species respectively. The results showed that the maternal behavior of the indigcnous sows was better than that of exotics, dominated by increasing 4-5 suckling per day and a strong intention to protect piglets. However, compared with that of exotic lactating sows, the appetite of the indigenous sows was poor. It was also indicated that redistribution of piglet highly influenced sows＇ maternal behavior and nursing. The difference of sensibility of both sows response to environmental changes was finally discussed.
