Behavioural response of pure Ankole and crossbred (Ankole * Holstein) cows to seasonal pasture variations in south-western Uganda
Contributor(s):: Idibu, J., Kabi, F., Mpairwe, D.
This study evaluated the effects of season and pasture species on variations in sward composition, pasture quantity (plant-height and biomass) and quality [crude protein (CP), neutral detergent fibre (NDF) and in vitro organic matter digestibility (IVOMD)]. Behavioural responses of a group of 10...
Slow and steady wins the race? No signs of reduced welfare in smaller broiler breeder hens at four weeks of age
Contributor(s):: Lindholm, C., Calais, A., Jonsson, J., Yngwe, N., Berndtson, E., Hult, E., Altimiras, J.
Broiler breeder chickens are commonly reared under strict feed-restriction regimes to reduce obesity-induced health and fertility problems during adult life, and are assumed to experience a reduced welfare due to the resulting hunger. In these conditions, feed competition could influence the...
The anthropozoology of domestication for milk productionAnthropozoologie de la domestication laitiere
Contributor(s):: Poplin, F.
Milk draws its substance from a living being of flesh and blood and from plant matter full of scents, through a two-cycle digestive system and fermentation in vivo, that of ruminants, which are also animals that provide meat ("you drink my milk, you eat my meat"). The pig, the "outlaw" of...
Gut microbiota of humans, dogs and cats: current knowledge and future opportunities and challenges
Contributor(s):: Deng, P., Swanson, K. S.
High-throughput DNA sequencing techniques allow for the identification and characterisation of microbes and their genes (microbiome). Using these new techniques, microbial populations in several niches of the human body, including the oral and nasal cavities, skin, urogenital tract and...
Nutritional and behavioral effects of gorge and fast feeding in captive lions
Contributor(s):: Altman, J. D., Gross, K. L., Lowry, S. R.
Nonhuman animals in captivity manifest behaviors and physiological conditions that are not common in the wild. Lions in captivity face problems of obesity, inactivity, and stereotypy. To mediate common problems of captive lions, this study implemented a gorge and fast feeding schedule that better...
Periods of early development and the effects of stimulation and social experiences in the canine
Contributor(s):: Battaglia, C. L.
It is not capacity that explains the differences that exist between individuals, because most seem to have far more capacity than they will ever use. The differences that exist between individuals seem to be related to something else. Researchers have studied these phenomena and have looked for...
What is the relationship between level of infection and 'sickness behaviour' in cattle?

Fish oil and barley supplementation in diets for adult dogs: effects on lipid and protein metabolism, nutrient digestibility, fecal quality. and postprandial glycemia
Contributor(s):: Maria Regina Cattai de Godoy, David L. Harmon (adviser)
Obesity is the most prevalent nutritional disorder encountered in small animal medicine. Problems related with obesity are the higher incidence of morbidity and mortality. Nutritional and physical activity interventions have been common strategies employed; however, they have shown low compliance...
The use of dosed and herbage n-alkanes as markers for the determination of digestive strategies of captive giraffes (Giraffa camelopardalis)

Cross-sucking and gradual weaning of dairy calves
| Contributor(s):: Passille, A. M. de, Sweeney, B., Rushen, J.
To examine the effect of gradually weaning calves off milk on cross-sucking, and the relationship between cross-sucking and energy intake, 32 Holstein calves were housed in groups of four and allowed 12 L/d of milk until the process of weaning began. The process of weaning was either abrupt at 41...
Discriminating among novel foods: effects of energy provision on preferences of lambs for poor-quality foods
| Contributor(s):: Villalba, J. J., Provenza, F. D.
A study was conducted to better understand how lambs discriminate among novel foods based on flavour and post-ingestive effects. The manner in which temporal sequence of food ingestion and post-ingestive feedback affected preference when lambs were fed flavoured wheat straw (a poorly nutritious...
Effects of space allowance on the grazing behaviour and spacing of sheep
| Contributor(s):: Sibbald, A. M., Shellard, L. J. F., Smart, T. S.
In each of two experiments, four groups of 10 female Scottish Blackface sheep grazed for 2 weeks at each of four space allowances, according to a Greco-Latin Square design. Space allowances were 80, 100, 133 or 200 m2 per head in experiment 1 and 50, 67, 100 or 200 m2 per head in experiment 2....
Estimating the diet of urban birds: the problems of anthropogenic food and food digestibility
| Contributor(s):: Ottoni, I., Oliveira, F. F. R. de, Young, R. J.
A variety of methods exist for assessing the diets of wild birds, each of which has its strengths and weaknesses. The objective of this study was to compare diet data collected in parallel by behavioural observations and faecal analysis from an urban population of Penelope superciliaris...
Feeding behaviour of sheep on shrubs in response to contrasting herbaceous cover in rangelands dominated by Cytisus scoparius L
| Contributor(s):: Pontes, L. da S., Agreil, C., Magda, D., Gleizes, B., Fritz, H.
The foraging responses of ewes faced with a diversity of feed items and their effects on broom (Cytisus scoparius L.) consumption were examined. The experiment was conducted on a farm in the autumn with ewes (n=33) grazing three small paddocks (0.44 ha on average, for at least 10 days each)...
Ingestive behaviour of heifers grazing monocultures of ryegrass or white clover
| Contributor(s):: Rutter, S. M., Orr, R. J., Penning, P. D., Yarrow, N. H., Champion, R. A.
The ingestive behaviour of dairy heifers grazing monocultures of either perennial ryegrass or white clover was characterized. Two different types of jaw movements were characterized: bites (i.e. when herbage was gathered in the mouth and then severed) and chews (i.e. when herbage severed by a...
Lambs fed protein or energy imbalanced diets forage in locations and on foods that rectify imbalances
| Contributor(s):: Scott, L. L., Provenza, F. D.
Ruminants eat a variety of foods from different locations in the environment. While water, cover, social interactions, and predators are all likely to influence choice of foraging location, differences in macronutrient content among forages may also cause ruminants to forage in different...
Oxytocin facilitates behavioural, metabolic and physiological adaptations during lactation
| Contributor(s):: Uvnas-Moberg, K., Johansson, B., Lupoli, B., Svennersten-Sjaunja, K.
This article aims to propose that oxytocin not only stimulates milk letdown, but also adapts behaviour and physiology to facilitate lactation in mammals, including dairy cattle. Circulating oxytocin as well as neurogenic oxytocin participates in these regulatory processes. In short, oxytocin...
Reduction in grass eating behaviours in the domestic dog, Canis familiaris , in response to a mild gastrointestinal disturbance
| Contributor(s):: McKenzie, S. J., Brown, W. Y., Price, I. R.
Grass eating behaviour in the domestic dog may be related to gastrointestinal distress. To explore this theory, the current study observed grass eating behaviours in dogs fed a standard diet with and without supplementation of a fructo-oligosaccharide (FOS). The FOS diet temporarily induced...
Does sward height affect feeding patch choice and voluntary intake in horses?
| Contributor(s):: Edouard, N., Fleurance, G., Dumont, B., Baumont, R., Duncan, P.
The numbers of horses grazing at pasture are increasing in developed countries, so a proper understanding of their feeding selectivity and of the tactics they use for extracting nutrients from swards is essential for the management of horses and grasslands. Resource acquisition in herbivores can...
