A comparison of daily total locomotor activity between the lactation and the dry period in dairy cattle

The objective of this study was to investigate the influence of farming management on the total locomotor activity (TLA) behaviour in dairy cattle. We recorded 24 h/day TLA in five not pregnant Holstein Friesian cows during parts of the lactation and dry periods, by means of an activity monitoring system (Actiwatch mini®) for seven days […]

The effect of photic entrainment and restricted feeding on food anticipatory activity in Ovis aries

The aim of this study was to investigate the influence of light/dark (L/D) cycle, associated with restricted feeding, on total daily locomotor activity in sheep. Eight clinically healthy Comisana ewes were housed individually in a soundproof box and subjected to three different light and feeding periods. During period 1 (light on 8:00; light off 20:00) […]

Circadian rhythms of redox states and total locomotor activity in dairy cattle

We want to study the circadian rhythm of dROMs and anti-oxidative power in dairy cattle during dry period and the possible involvement of the circadian organization of rest/activity cycles in the fluctuation of redox state. For this purpose we recorded TLA in five clinically healthy Bruna Italian dairy cattle by means of an actigraphy-based data […]

Photic and non‐photic entrainment on daily rhythm of locomotor activity in goats

We studied the photic (L/D cycle) and non‐photic (restricted feeding) entrainment on the patterns of daily rhythm of total locomotor activity in goats. Six female Maltese goats were subjected to three different artificial L/D cycles: 12/12 L/D, 12/12 D/L and constant light. During the 12/12 L/D and 12/12 D/L, food and water were available ad […]

Evaluation of total locomotor activity and oxidative markers daily rhythms in sheep

For our study, five clinically healthy Comisana sheep, housed individually in a soundproof light-tight box, were exposed to artificial photoperiod (12/12 light/dark). Locomotor activity was continuously recorded and blood samples were collected every 3 h over a 24 h period. On blood samples, reactive oxygen metabolites (dRoms), antioxidant barrier (Oxy-ads) and thiol-antioxydant barrier (SHp) were […]

Daily locomotor activity in five domestic animals

The aim of this study was to compare locomotor activity in five domestic animals. Five female Comisana sheep, five female Maltese goats, five female Bruna cows, and five female Thoroughbred horses were housed separately in a soundproof box equipped with an airflow system and five female Blue Vienna rabbits were individually housed in metallic cages. […]

Daily rhythms of 25 physiological variables in Bos taurus maintained under natural conditions

To further understanding of the multiple temporal relationships of the physiological process, we monitored simultaneously 25 different variables in individual cows. We used 6 Bruna Italiana non – pregnant and non – lactating cows from the same farm. The animals were housed individually in a 12 m2 box under natural 14/10 light/dark cycle. They were […]

Effects of weight loss on heart rate normalization and increase in spontaneous activity in moderately exercised overweight dogs

The objective of this study was to evaluate the impact of weight loss on heart rate normalization at rest and during moderate exercise in overweight dogs. Spontaneous physical activity level evolution in relation with weight loss was also assessed. A group of 15 overweight dogs (average body condition score, BCS=7 on a 9-point scale) were […]

Seasonal change of daily motor activity rhythms in Capra hircus

To evaluate if seasonal changes in photoperiod and temperature were associated with changes in total daily motor activity we recorded the total daily motor activity of five clinically healthy goats at four different times of the year (vernal equinox, summer solstice, autumn equinox and winter solstice). Goats were housed under natural photoperiod and natural ambient […]

Circadian activity rhythm in sheep and goats housed in stable conditions

The aim of this study was to establish the circadian rhythm of total activity in sheep and goats kept in housed conditions. For our study five Comisana breed sheep and five Maltese breed goats were kept in an individual box of 12 m2 under artificial 12/12 light/dark cycle for 14 days. We equipped the animals […]

Locomotor activity and serum tryptophan and serotonin in goats: daily rhythm

The goal of the present study was to investigate the daily amount of motor activity and the daily rhythm of tryptophan and serotonin in goats housed in individual boxes under a 12/12 light/dark cycle. We equipped six Girgentana breed goats with Actiwatch-Mini® (Cambridge Neurotechnology Ltd., UK), actigraphy-based data loggers that record a digitally integrated measure […]

Seasonal variations in daily rhythms of activity in athletic horses

Circadian rhythms reflect extensive programming of biological activity that meets and exploits the challenges and opportunities offered by the periodic nature of the environment. In the present investigation, we recorded the total activity of athletic horses kept at four different times of the year (vernal equinox, summer solstice, autumn equinox and winter solstice), to evaluate […]

Daily rhythms of activity in horses housed in different stabling conditions

Total locomotor activity was studied in 10 Thoroughbreds housed under a natural 12/12 light/dark cycle. Five horses were housed in individual boxes, and five were housed in individual boxes with a paddock. In order to record locomotor activity, on each horse was placed an Actiwatch-Mini® (Cambridge Neurotechnology Ltd, UK), actigraphy-based data loggers that record a […]

Exercise Heart Rate and Blood Lactate Responses as Indicators of Aerobic Capacity in Dogs

The objective of this study was to quantify the intensity of different types of exercise by measuring heart rate and blood lactate level in sled dogs to better understand their aerobic capacities. Fourteen Alaskan huskies (seven males, seven females; age: 2.4 ± 0.4 years old; weight: 21.9 ± 0.9 kg) were involved in mild (45-minute […]

Effects of restricted feeding on circadian activity rhythms of sheep—A brief report

The purpose of the present experiment was to investigate the impact of timed restricted feeding on the behavioural circadian organization of sheep. For this purpose, total activities of sheep subjected both to 12-h light:12-h dark (12:12 LD) cycle and to periodic food-availability during the dark phase were recorded. When food was available ad libitum, sheep […]

A novel method for activity monitoring in small non-human primates

Patterns of spontaneous activity are valuable reflections of well-being in animals and humans and, because of this, investigations have frequently incorporated some form of activity monitoring into their studies. It is widely believed that activity monitoring, alongside assessments of general behaviour, should be included in initial CNS safety pharmacology screening. As the number of marmoset […]
