Farrowing Behaviour And Stillbirth In Two Environments: An Evaluation Of The Restraint-Stillbirth Hypothesis, D. Fraser, P. A. Phillips, B. K. Thompson
Reproductive Behavior Collection
A total of 59 farrowings were studied in either a conventional, narrow farrowing crate (0.43 m wide) or a much wider alternative design with sides spaced 1.2 m apart at the sow’s standing height but narrowing near the floor to limit the sow’s lying area. Using video recording, we monitored each “birth interval” (i.e. the period between two successive births) and noted the interval’s length, the sow’s posture and postural changes during the interval, and whether the interval ended with a live-born or stillborn piglet. The wide and conventional crates did not differ significantly in median interval between piglets (15.9 …
Weapon Size Versus Body Size As A Predictor Of Winning In Fights Between Shore Crabs, Carcinus Maenas (L.), Lynne U. Sneddon, Felicity A. Huntingford, Alan C. Taylor
Weapon Size Versus Body Size As A Predictor Of Winning In Fights Between Shore Crabs, Carcinus Maenas (L.), Lynne U. Sneddon, Felicity A. Huntingford, Alan C. Taylor
Veterinary Science and Medicine Collection
Relative body size (carapace width) and weapon size (chela length) were used as indicators of resource holding potential (RHP) in the agonistic behaviour of male shore crabs, Carcinus maenas (L.). Weapon size was found to be a more reliable predictor of the outcome of pairwise fights than body size. Crabs with longer chelae than their opponents were more likely to win fights than crabs with relatively larger bodies. Body size had less influence on the outcome of fights. Relative body and weapon size did not influence initiation of contests but did affect the likelihood of winning; however, this was significant …

The Scientific Validity Of Subjective Concepts In Models Of Animal Welfare, Françoise Wemelsfelder
The Scientific Validity Of Subjective Concepts In Models Of Animal Welfare, Françoise Wemelsfelder
Animal Welfare Collection
This paper takes a closer look at the subjectivity/objectivity relationship, as it plays a role in the science of animal welfare. It argues that subjective, experiential states in animals such as well-being and suffering are, contrary to what is often assumed, open to empirical observation and scientific assessment. The presumably purely private, inaccessible nature of such states is not an inherent property of these states, but derives from their misguided conception as ‘causal objects’ in mechanistic models of behaviour. This inevitably endows subjective experience with a ‘hidden’ status. However, subjective experience should be approached on its own conceptual grounds, i.e. …
