Title (up) Common Feeding Practices Pose A Risk to the Welfare of Horses When Kept on Non-Edible Bedding Type Journal Article
Year 2020 Publication Animals Abbreviated Journal Animals
Volume 10 Issue Pages 441
Keywords horse behaviour; feed intake pause; bedding; welfare indicator; feeding practices; roughage; horse welfare; individual housing system
Abstract During the evolution of the horse, an extended period of feed intake, spread over the entire 24-h period, determined the horses� behaviour and physiology. Horses will not interrupt their feed intake for more than 4 h, if they have a choice. The aim of the present study was to investigate in what way restrictive feeding practices (non ad libitum) affect the horses� natural feed intake behaviour. We observed the feed intake behaviour of 104 horses on edible (n = 30) and non-edible bedding (n = 74) on ten different farms. We assessed the duration of the forced nocturnal feed intake interruption of horses housed on shavings when no additional roughage was available. Furthermore, we comparatively examined the feed intake behaviour of horses housed on edible versus non-edible bedding. The daily restrictive feeding of roughage (2 times a day: n = 8; 3 times a day: n = 2), as it is common in individual housing systems, resulted in a nocturnal feed intake interruption of more than 4 hours for the majority (74.32%, 55/74) of the horses on shavings (8:50 ± 1:25 h, median: 8:45 h, minimum: 6:45 h, maximum: 13:23 h). In comparison to horses on straw, horses on shavings paused their feed intake less frequently and at a later latency. Furthermore, they spent less time on consuming the evening meal than horses on straw. Our results of the comparison of the feed-intake behaviour of horses on edible and non-edible bedding show that the horses� ethological feeding needs are not satisfied on non-edible bedding. If the horses accelerate their feed intake (also defined as �rebound effect�), this might indicate that the horses� welfare is compromised. We conclude that in addition to the body condition score, the longest duration of feed intake interruption (usually in the night) is an important welfare indicator of horses that have limited access to roughage.

Title (up) Development and validation of a sensitive ELISA for quantification of secretory IgA in rat saliva and faeces Type Journal Article
Year 2001 Publication Laboratory Animals Abbreviated Journal
Volume 35 Issue 4 Pages 301-306
Keywords
Abstract Non-invasive measures of immunological markers are an attractive means of stress assessment in laboratory animals. Salivary IgA has been used successfully as a stress marker in the human, and several reports indicate the potential of secretory IgA as a non-invasive measure of stress in animals. The present paper describes the development of an ELISA using commercially available components for the quantification of rat IgA and validation of this assay for the quantification of rat secretory IgA in saliva and faeces. The concentration of IgA in rat saliva varied significantly between duplicate samples obtained from individual rats, and the viscosity and small total volume of rat saliva gave unsatisfactory results for IgA. Faecal IgA was present in high concentrations, and duplicate samples varied by only 2-3%. However, faecal IgA seemed less stable than IgA in other biological compartments, and this finding must be taken into consideration when using quantitative measurements of IgA as a marker of mucous humoral immune status.

Title (up) Effect of oestrous-cycle stage on the response of mares in a novel object test and isolation test Type Journal Article
Year 2005 Publication Reproduction in Domestic Animals = Zuchthygiene Abbreviated Journal Reprod Domest Anim
Volume 40 Issue 5 Pages 480-488
Keywords Animals; Behavior, Animal/*physiology; Cross-Over Studies; Diestrus/*physiology; Estrus/*physiology; Female; Heart Rate/*physiology; Horses/*physiology; Questionnaires
Abstract In various species, sex, hormonal treatments and oestrous-cycle stage have been shown to affect the animal's response in behavioural tests. Few such studies have been performed in the horse. The main aim of the present study was to investigate whether oestrous-cycle stage affects mares' response to a novel object test and isolation test and, in part, to study whether mares, assumed to suffer from oestrous-related behavioural problems, respond differently in these tests when compared with controls. Twelve mares were tested twice, in oestrus and dioestrus, in a crossover design. Seven behavioural and two heart rate variables were measured for the novel object test and two heart rate variables for the isolation test. Oestrous-cycle stage and whether a mare was classified as a 'problem' mare did not affect the mare's response. However, test order, i.e. the cycle stage a mare was tested in first, affected its reaction. This effect could partly be explained by significant differences between test occasions 1 and 2 in three behavioural variables and one heart rate variable (p < 0.05) in the novel object test. The mares explored the novel object more and had a higher mean heart rate in the first test. Exploring the novel object more could largely be attributed to those mares tested in dioestrus first, perhaps indicating that the mares in oestrus were less receptive to the novel object. The reason for the differences between test occasions could be an effect of learning or habituation.
