季节对犊牛行为的影响研究

Study on the Behavior of Qinchuan Calves in Different Seasons

为了研究秦川牛犊牛舒适的生活环境,提高犊牛饲养管理技术,本试验通过研究不同季节情况下,秦川牛犊牛的体表温度、呼吸频率、采食行为、反刍行为、排泄行为及运动行为等生理参数的变化,拟为犊牛的健康养殖提供数据支撑。结果表明:夏季犊牛的体表温度最高为37.24℃,与其它三季相比差异显著(P<0.05);夏季犊牛呼吸频率最高为53.30次/min,与其它三季相比差异显著(P<0.05);夏季犊牛的采食时间最低为43.35s,与其它三季相比差异显著(P<0.05);夏季犊牛反刍咀嚼时间最低为31.87s,与其它三季相比差异显著(P<0.05);夏季犊牛排粪次数为3.43次、排尿次数为6次、饮水次数为5次都最高,与其它三季的排泄行为差异显著(P<0.05);夏季犊牛卧息时间最长为311.00 min,与冬季相比差异显著(P<0.05)。研究结果表明,高温对秦川牛犊牛的行为影响最大。

In order to study comfortable living environment of Qinchuan calves and improve the feeding and management techniques,this experiment studied the variation of different physiological parameters of Qinchuan calves such as skin temperature,respiratory rate,feeding behavior,rumination behavior,excretion behavior and sports behavior in different seasons in order to provide data support for healthy calf breeding.The results showed that the maximum skin temperature of calves in summer was 37.24 ℃,which was significantly different from that of other three seasons(P<0.05).The respiratory frequency in summer was 53.30 times/min,significantly different from that of other three seasons(P<0.05).The minimum chewing time of calves in summer was 31.87 s,which was significantly different from that of other three seasons(P<0.05).The number of defecation was 3.43 times,the frequency of urination was6 times and the number of drinking water was 5 times,which were all significantly different from that of other three seasons(P<0.05).The maximum time for resting in recumbency position in summer was311.00 min,which was significantly different from that of winter(P<0.05).It indicates that high temperature has the greatest impact on the Qinchuan calves.
