Abstract

ABSTRACT The daily pattern of total locomotor activity (TLA) of cattle kept in different housing conditions was investigated in order to evaluate whether TLA could be used as a useful index of animal welfare. Twenty Modicana cattle were divided into two equal groups: Group A, housed in a grazing area of 5 hectare, and Group B, housed in a paddock of 200 m2. Animals were equipped with activity-monitoring data loggers (Actiwatch-Mini®) to record the daily TLA for 7 days. The trigonometric statistical model, used to describe the rhythmic parameters (mesor, amplitude, acrophase and robustness of rhythm), indicated a diurnal rhythm of TLA in cattle. Animals belonging to Group B showed lower TLA, an anticipation of acrophase (time of activity peak) of TLA, and lower values of Mesor, amplitude and robustness of rhythm compared to Group A (p < 0.05). These results suggest that cattle in the paddock condition showed disturbed physiological characteristics of TLA displaying a flattening in its daily pattern compared to animals kept in the grazing area. This aspect should be taken into consideration of farming management in the planning of housing conditions, which should respect the requirement of locomotor activity and related physiological behaviors of cattle in order to guarantee the animal welfare.

奶牛舍系统影响奶牛每日总运动活动(TLA)

摘要研究了不同圈养条件下牛的每日总运动活动(total locomotor activity, TLA)模式，以评价TLA是否可以作为动物福利的有用指标。20头莫迪卡纳牛被分为两组:A组饲养在5公顷的放牧区内，B组饲养在200平方米的围场内。动物配备活动监测数据记录仪(Actiwatch-Mini®)记录7天的每日TLA。利用三角统计模型描述节律参数(节律的中频、振幅、端相和鲁棒性)，揭示了牛TLA的昼夜节律。与A组相比，B组动物的TLA较低，TLA的峰期(活动高峰时间)预期较低，节律的Mesor值、振幅值和稳健性较低(p < 0.05)。这些结果表明，与放牧区相比，围场条件下的牛的TLA生理特征受到干扰，其日常模式趋于平坦。畜舍条件的规划应考虑到这一点，畜舍条件的规划应尊重牛的运动活动和相关生理行为的要求，以保证动物福利。

期刊介绍： The principal aim of Biological Rhythm Research is to cover any aspect of research into the broad topic of biological rhythms. The area covered can range from studies at the genetic or molecular level to those of behavioural or clinical topics. It can also include ultradian, circadian, infradian or annual rhythms. In this way, the Editorial Board tries to stimulate interdisciplinary rhythm research. Such an aim reflects not only the similarity of the methods used in different fields of chronobiology, but also the fact that many influences that exert controlling or masking effects are common. Amongst the controlling factors, attention is paid to the effects of climate change on living organisms. So, papers dealing with biometeorological aspects can also be submitted. The Journal publishes original scientific research papers, review papers, short notes on research in progress, book reviews and summaries of activities, symposia and congresses of national and international organizations dealing with rhythmic phenomena.
