Ability of owners to identify resource guarding behaviour in the domestic dog
Contributor(s):: Jacobs, Jacquelyn A., Pearl, David L., Coe, Jason B., Widowski, Tina M., Niel, Lee
Canine resource guarding (RG) describes the behaviour used by a dog to achieve or maintain control over an item of perceived value. Three distinct behavioural patterns of RG have been proposed; rapid ingestion (i.e., rapid consumption of an edible item), avoidance (i.e., positioning of the head...
Feed resource selection of Criollo goats is the result of an interaction between plant resources, condensed tannins and Haemonchus contortus infection
Contributor(s):: Torres-Fajardo, Rafael Arturo, González-Pech, Pedro Geraldo, Ventura-Cordero, Javier, Ortíz-Ocampo, Guadalupe Isabel, Sandoval-Castro, Carlos Alfredo, Torres-Acosta, Juan Felipe Jesús
The tropical deciduous forest (TDF) is an ecosystem with a heterogeneous array of plant species containing different condensed tannin (CT) content. Recent studies explored the effect of polyethylene glycol (PEG) or Haemonchus contortus infection on the intake and feed resource selection of goats....
Quantitative assessment of human and pet exposure to Salmonella associated with dry pet foods
Contributor(s):: Lambertini, E., Buchanan, R. L., Narrod, C., Ford, R. M., Baker, R. C., Pradhan, A. K.
Recent Salmonella outbreaks associated with dry pet foods and treats highlight the importance of these foods as previously overlooked exposure vehicles for both pets and humans. In the last decade efforts have been made to raise the safety of this class of products, for instance by upgrading...
Conservation implications of dietary dilution from debris ingestion: sublethal effects in post-hatchling loggerhead sea turtles
Contributor(s):: Shannon J. McCauley, Karen A. Bjomdal
Ingestion of anthropogenic debris by marine species has been documented extensively; fewer studies have attempted to quantify the sublethal effects caused by debris ingestion. One potential sublethal effect is reduced nutrient gains from diets diluted by consumption of debris. Post-hatchling and...

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...

Combining an active transponder system with sprayed n -alkanes to quantify investigative and ingestive grazing behaviour of dairy cattle in pastures treated with slurry
| Contributor(s):: Swain, D. L., Friend, M. A., Mayes, R. W., Wilson, L. A., Hutchings, M. R.
This paper explores the interaction of grazing pregnant dairy cattle (lactating and non-lactating) with contaminated pasture. Behavioural responses were divided into investigative and ingestive grazing events. Patches of sward were artificially contaminated with slurry (containing faeces and...
Development of ingestive behaviour and the relationship to belly nosing in early-weaned piglets. (Special Issue: Early Weaning.)
| Contributor(s):: Widowski, T. M., Torrey, S., Bench, C. J., Gonyou, H. W.
Over the last 30 years, improvements in diet formulations have resulted in a steady decline in weaning age while still meeting the nutritional needs of the piglets. However, even with their dietary requirements met, many piglets still experience a number of difficulties at weaning. Piglets weaned...
Feeding behaviour and caecotrophy in the young rabbit before weaning: an approach by analysing the digestive contents
| Contributor(s):: Orengo, J., Gidenne, T.
Young rabbits consume milk, feed and soft faeces during the preweaning period, but the biological rhythm of intake were scarcely described. This work aimed to analyse the behaviour of ingestion and caecotrophy by analysing the stomach and rectal contents of young rabbits. Chronological samplings...
An analysis of regurgitation and reingestion in captive chimpanzees
| Contributor(s):: Baker, K. C., Easley, S. P.
Regurgitation and reingestion (R/R) is a potentially self-injurious behaviour in nonhuman primates and is a common problem among captive primates. The temporal and contextual distribution of R/R and its relationship to diet were assessed in 13 indoor-housed chimpanzees living in pairs and trios....
Feeding behaviour and diet selection of finishing Limousin bulls under intensive rearing system
| Contributor(s):: Cozzi, G., Gottardo, F.
Twenty Limousin finishing bulls (initial body weight=425.9+or-22.0 kg) were assigned to four balanced groups reared in separate pens with a space allowance of 3.6 m2 per head and a manger space of 95 cm per head. The finishing period lasted 138 days during which the animals received the same diet...
Multiple releases of stable flies ( Stomoxys calcitrans L.) and behaviour of grazing beef cattle
| Contributor(s):: Dougherty, C. T., Knapp, F. W., Burrus, P. B., Willis, D. C., Cornelius, P. L., Bradley, N. W.
A change-over statistical design with complete balance of first residual effects was used with a tethered grazing technique to evaluate the effects of arthropod ectoparasites on the behaviour of adult Angus beef cows (Bos taurus; body weight (BW), 465+or-30 kg) grazing vegetative tall fescue...
