Consumption Of Solid Food By Suckling Pigs: Individual Variation And Relation To Weight Gain, Edmond A. Pajor, David Fraser, Donald L. Kramer
Consumption Of Solid Food By Suckling Pigs: Individual Variation And Relation To Weight Gain, Edmond A. Pajor, David Fraser, Donald L. Kramer
Feeding Behavior Collection
Individual daily consumption of supplementary solid food ('creep feed') was measured from Day 10 to weaning at Day 28 for 39 piglets in four litters, and its relationship to body weight and weight gain up to Day 42 was investigated. Individual consumption was measured by combining the weight of the feed removed from the dispensers (monitored electronically) and a video image of piglet activity at the feeder. Creep feed consumption varied greatly, both between and within litters. On average, pigs began feeding on Day 12 (range Day 10-28), intake was relatively low (usually < 5 g day ‒1) until Day 20 but increased …
Enhanced Attraction To Blood By Pigs With Inadequate Dietary Protein Supplementation, David Fraser, D. E. Bernon, R. O. Ball
Enhanced Attraction To Blood By Pigs With Inadequate Dietary Protein Supplementation, David Fraser, D. E. Bernon, R. O. Ball
Nutrition Collection
In two experiments, 60 individually penned growing pigs were exposed daily to two sections of cotton cord, one of which had been soaked with pigs' blood and subsequently dried, while the other was plain. The animals' preference for chewing-on the blood-impregnated cord was quantified by direct observation. When fed a standard "control" diet of corn, barley, and soybean meal with mineral and vitamin supplements, the pigs had a clear but modest preference for chewing the blood-impregnated cord. Omission of the protein supplement (soybean meal) from the diet for 4 wk led to a major increase in attraction to blood and …

Kin Recognition In Vertebrates: What Do We Really Know About Adaptive Value?, Andrew R. Blaustein, Marc Bekoff, John A. Byers, Thomas J. Daniels
Kin Recognition In Vertebrates: What Do We Really Know About Adaptive Value?, Andrew R. Blaustein, Marc Bekoff, John A. Byers, Thomas J. Daniels
Sentience Collection
The ability of an animal to discriminate between kin and non-kin (kin recognition) has been the subject of numerous recent investigations. Grafen (Anim. Behav., 1990, 39, 42-54) recently reported that the evidence in support of kin recognition is weak and the data illustrating a preference for kin to associate in the laboratory may be more consistently explained as species recognition. It is suggested here, however, that in many cases it may be impossible to distinguish between species recognition and kin recognition, but in some cases, kin recognition seems apparent. It is also emphasized that very little is known about the …
Effect Of Straw On The Behaviour Of Growing Pigs, David Fraser, P. A. Phillips, B. K. Thompson, T. Tennessen
Effect Of Straw On The Behaviour Of Growing Pigs, David Fraser, P. A. Phillips, B. K. Thompson, T. Tennessen
Social Behavior Collection
The effects of straw on the behaviour of young growing pigs were studied in two experiments. In Experiment 1, group of three pigs, aged about 7 weeks, were housed in raised decks with or without straw bedding. Time-lapse video recording showed no major differences between treatments in the amount or daily pattern of overall activity and feeding. Detailed observations showed that bedding reduced the incidence of rooting and chewing on pen-mates, but had little effect on other social activities such as mounting and aggressive biting. Experiment 2 compared groups of eight growing pigs aged about 10 weeks, housed in floor …
Puppy Mills Exposed
Close Up Reports
Thousands of dogs, unloved, starving, ill-housed; thousands of puppies, shipped like so much merchandise at too young an age; thousands of consumers, unknowingly buying sick dogs: these are the grim truths of the puppy-mill trade.
Animals In Biomedical Research: The Undermining Effect Of The Rhetoric Of The Besieged, John P. Gluck, Steven R. Kubacki
Animals In Biomedical Research: The Undermining Effect Of The Rhetoric Of The Besieged, John P. Gluck, Steven R. Kubacki
Experimentation Collection
It is correctly asserted that the intensity of the current debate over the use of animals in biomedical research is unprecedented. The extent of expressed animosity and distrust has stunned many researchers. In response, researchers have tended to take a strategic defensive posture, which involves the assertation of several abstract positions that serve to obstruct resolution of the debate. Those abstractions include the notions that the animal protection movement is trivial and purely anti-intellectual in scope, that all science is good (and some especially so), and the belief that an ethical consensus can never really be reached between the parties.
Reflective Ethology, Applied Philosophy, And The Moral Status Of Animals, Marc Bekoff, Dale Jamieson
Reflective Ethology, Applied Philosophy, And The Moral Status Of Animals, Marc Bekoff, Dale Jamieson
Experimental Research and Animal Welfare Collection
Currently there is an unprecedented interest in ethological studies of nonhuman animals. Much of this interest is motivated by a desire to learn more about animals themselves. For scientists assuming this stance, a secondary goal is to use this knowledge to assess the place of humans in the natural order of things, stressing continuity or discontinuity depending on one's views. Others, however, study animals primarily to apply this knowledge to human behavior. We argue that behavioral research demands the rigorous application of methods that are minimally harmful to the animals being studied. We argue for a moderate, but rigorous and …
