Comprehension Of "Absence" By An African Grey Parrot: Learning With Respect To Questions Of Same/Different, Irene M. Pepperberg

Sentience Collection

An African Grey parrot, Alex, learned to report on the absence or presence of similarity and difference between two objects. Alex was shown pairs of objects that were (a) totally dissimilar, (b) identical, or (c) similar or different with respect to one of three attributes (color, shape, or material). In the first two cases, he responded to the respective queries of "What's same?" or "What's different?" with the vocalization "none," and in the third case he responded with the appropriate category label ("color," "shape," or "mah-mah" [matter]). His accuracy was 80.9% to 83.9% for pairs of familiar objects not used …

Variation In Piglet Weights: Weight Gains In The First Days After Birth And Their Relationship With Later Performance, B. K. Thompson, D. Fraser

Ontogeny Collection

Piglets from 42 litters of Yorkshire sows were weighed 0, 1, 2, 3, 4, 5, 7, 10, and 14 d after farrowing in order to explore the highly variable weight gains during the first 2 wk after birth. All litters were adjusted to 10-12 piglets by fostering. Litters differed greatly in average gain per piglet during the first 3 d after farrowing, with litter means ranging from 5 to 227 g d‒1 per piglet for the 3-d period. Gains during days 0-3 tended to be somewhat lower if the sow had a high body temperature during these days, but the …

Use Of Water By Piglets In The First Days After Birth, David Fraser, P. A. Phillips, B. K. Thompson, W. B. Peeters

Ontogeny Collection

Use of drinking water was determined for 51 litters of piglets by weighing and refilling a water dispenser each day for the first 4 d after farrowing. Measures of spillage, evaporation, and piglet drinking behavior indicated that most disappearance of water represented actual drinking by the piglets. Water use varied greatly among litters with an average of 46 g d^‒1 per piglet over the 4 d, and a range of negligible use to about 200 g d^‒1. Water use, especially on day 2, was correlated negatively with the average weight gain of the litter during the first …

Histology Of The Ovaries And Fat Bodies Of Chthonerpeton Indistinctum, Rafael O. De Sá, Nibia Berois

Biology Faculty Publications

Histological analysis revealed three different stages in the development of ovarian follicles of Chthonerpeton indistinctum. These stages are identified by (1) location of the oocyte in the ovary wall, (2) oocyte morphology and staining characteristics, (3) development of the zona pellucida, and (4) organization of the follicular layer. Atretic follicles and corpora lutea also were found. Fat bodies are composed of well-developed adipose tissue.

Eavesdropping By Bats: The Influence Of Echolocation Call Design And Foraging Strategy, Jonathan Balcombe, M. Brock Fenton

Sentience Collection

We used playback presentations to free-flying bats of 3 species to assess the influence of echolocation call design and foraging strategy on the role of echolocation calls in communication. Near feeding sites over water, Myotis lucifugus and M. yumanensis responded positively only to echolocation calls of conspecifics. Near roosts, these bats did not respond before young of the year became volant, and after this responded to presentations of echolocation calls of similar and dissimilar design. At feeding sites Lasiurus borealis responded only to echolocation calls of conspecifics and particularly to "feeding buzzes". While Myotis, particularly subadults, appear to use the …

Contingency Analysis Of The Agonistic Behavioral Sequence In Sceloporus Undulatus Hyacinthinus, Deborah Allison

Masters Theses & Specialist Projects

A contingency analysis of the sequence of actions associated with agonistic behavior of resident and introduced male Sceloporus undulatus nya irthirus was carried out to determine the degree of stereotypy. During the time period April to June 1984 and 1985, caged pairs of adult male and juvenile female lizards were filmed on three occasions in order to gather data on resident males not involved in aggressive interactions. During the same threemonth time period, a different nonresident male was introduced singly into a given resident's cage on three occasions and the interactions filmed. The films were analyzed to determine which actions …

Cardiac Correlates Of Individual Recognition In The Chimpanzee (Pan Troglodytes), Sarah T. Boysen, Gary G. Berntson

Sentience Collection

The ability of a chimpanzee to recognize individuals depicted in photographs was evaluated through the use of heart rate measures. Heart rate was recorded before and during photographic projections of human caregivers, familiar individuals, strangers, and blank control slides. In the absence of explicit training or reinforcement, the chimpanzee displayed a differential pattern of heart rate response to the stimulus categories. Although heart rate responses to all stimuli were predominantly deceleratory, the photographs of caregivers yielded consistently larger responses than other stimuli. Results indicate that the chimpanzee is able to recognize individual humans from novel photographic representations and that heart …

Study Of A Small Mammal Population In Bowling Green, Kentucky, Richard Cambron

Masters Theses & Specialist Projects

The small mammal population of a restricted study area was live-trapped on the University farm at Western Kentucky University from November 1984 through November 1985. A total of 1800 trap-nights yielded 81 different individuals representing five species. Members of the genera Peromyscus and Microtus were the dominant individuals representing over 90% of the total. Also caught were Mus musculus and Blarina brevicauda. The members of the two major genera were examined for population size and dynamics. In addition, a statistical analysis was carried out on the randomness of the location of the home ranges. This analysis gave evidence that …

Variation In Piglet Weights: Development Of Within-Litter Variation Over A 5-Week Lactation And Effect Of Farrowing Crate Design, B. K. Thompson, D. Fraser

Ontogeny Collection

Piglets from 51 litters were weighed weekly over a 5-wk lactation in an experiment that studied the effects of farrowing crate design and other factors on variation in piglet weight. Of two farrowing crates used, one had low horizontal bars that tended to impede access to the upper row of teats, while the other had angled vertical bars which permitted freer access. Fourteen-day weights were more uniform in the vertical-bar crates than in the horizontal-bar crates (P < 0.025), but the difference waned by day 35 (P > 0.05). There were no significant differences in mean body weight owing to crate type (P < 0.05) for any of the weekly measurements but, by day 14, there was a significant linear trend (P < 0.05) at decreasing main body weight with increasing litter size. The interaction between crate type and litter size was significant at the later ages (P < 0.01 at day 35) because the linear trend was more pronounced for horizontal-bar crates than for vertical. Litters differed greatly in the uniformity of their body weights. Much of the variation became established in the first and, to a lesser extent, the second week after birth. In those weeks, weight gains were highly variable and were not closely related to weight at the beginning of the week. Thereafter, the established differences tended to be perpetuated to 35 d, because weight gains were largely proportional to body weight. Within-litter competition appeared to influence weight gain considerably.

Survey Of Parasite Control Practices In Sheep And Cattle, J R. Edwards, R V R Gwynn, R A. Love, Richard Thomas Norris, G Dalton-Morgan, Brown Besier

Technical Bulletins

Farms in the Albany, Esperance, Jerramungup and Katanning districts were surveyed to determine parasite control strategies currently used, to evaluate the adoption of recommended control practices and to detect areas of ineffective parasite control. For cattle, the number of drenches given in the low rainfall zone was higher than the number given in the high rainfall zone.

Variation In Piglet Weights: Relationship To Suckling Behavior, Parity Number And Farrowing Crate Design, David Fraser, B. K. Thompson

Ontogeny Collection

Suckling behavior and weight change of piglets were studied during the first 2 wk after birth. Thirty-six litters comprised a balanced comparison of parity number (first or second), litter size (8, 10 or 12), and two farrowing crate designs, one of which had a low horizontal bar that tended to impede the piglets' access to the udder. Piglets showed the expected preference for the anterior teats although the preference was more apparent in the second parity than in the first. Teat fidelity was most pronounced at the two ends of the udder; piglets occupying the middle positions did more fighting …

Atrophic Rhinitis In Pigs, A R. Mercy

Journal of the Department of Agriculture, Western Australia, Series 4

Severe atrophic rhinitis in pigs recurred recently in Australia after an apparent absence of some 20 years. The first of these recent cases occurred in a Westerm Australian herd in late 1984 and since then six other local herds have reported the disease. Severe atrophic rhinitis has also been seen recently in South Australia.

Atrophic rhinitis is a complex disease which causes degeneration of the nasal cavity, twisting of the snout and sometimes occasional bleeding from the nose.

It occurs only in pigs and severely affected animals may have a slower growth rate.

Animal Pain, Bernard E. Rollin

Experimentation Collection

Some time ago, I received a telephone call from an eminent primatologist asking me to give the keynote address at a scientific seminar on animal pain. My first response was to express surprise that they were inviting a philosopher. His reply was remarkable, if only for its rarity among scientists: "The truly interesting and important issues concerning pain in animals are not scientific ones," he said. "They are moral, philosophical, and conceptual ones. And the total failure of science to engage or even acknowledge these issues discredits biomedical science and weakens its conceptual base." I hope to show you that …

Recognition And Alleviation Of Pain In Animals, P. A. Flecknell

Animal Welfare Collection

The pain and distress which animals experience as a consequence of their use by man figures prominently in discussions of animal welfare. Some improvements have been made in animal housing and husbandry practices and it is likely that further progress will be made in this field. In comparison, relatively little attention has been given to the problem of minimizing the pain and distress caused to animals by the various procedures to which they are subjected. The most publicized of these are the wide range of experimental techniques which are undertaken using laboratory animals, but also includes procedures such as castration …

T-61 Use In The Euthanasia Of Domestic Animals: A Survey, Andrew N. Rowan

Veterinary Science and Medicine Collection

A variety of techniques have been proposed and employed for the killing of domestic animals but relatively few have survived as suitable agents for euthanasia-namely, the induction of painless, suffering-free death. Some agents, such as strychnine, curariform agents, or potassium salts cause suffering while others have other disadvantages. 'lbday, dogs and cats are commonly euthanatized with sodium pentobarbital or with T-61 which is a mixture of a central nervous system narcotic, a paralytic agent, and a local anesthetic. The use of T-61 was first reported in the United States in 1963 (Quin 1963). The substance gradually became more popular because …

Applications Of Laboratory Technology In The Evaluation Of The Risk Of Rabies Transmissions By Biting Dogs And Cats, Donald C. Blenden, Manuel J. Torres-Anjel, F. T. Satalowich

Veterinary Science and Medicine Collection

While rabies is not a common disease in domestic animal species of the United States, potential exposures to rabies in the form of bites are very common and increasing. A nationwide study conducted among general hospitals shows that 1 percent of emergency room visits are for animal bites, of which 80-90 percent are inflicted by the dog (Callaham 1980). This figure is conservative, as the study did not include pediatric hospitals, the bite of victims that progress only to a physician's office, or those that receive no medical care at all. In Missouri alone, this study would infer about 1500 …

Isolation Of Lactoferrin And Its Concentration In Sows’ Colostrum And Milk During A 21-Day Lactation, J. I. Elliot, B. Senft, G. Ernhardt, D. Fraser

Nutrition Collection

Levels of lactoferrin, an Fe-binding protein with bacteriostatic properties, were determined in the colostrum and milk of Yorkshire sows during a 21-d lactation. Lactoferrin levels averaged 1,100 to 1,300 μg/ml near the time of farrowing, then declined sharply during the first week of lactation. Concentration of lactoferrin showed considerable variation among sows, but not among teat positions (anterior to posterior). A method for isolating high purity swine lactoferrin is described.
