Title Feed preferences of ponies Type Journal Article
Year 1985 Publication (down) Equine Veterinary Journal Abbreviated Journal Equine Vet J
Volume 17 Issue 1 Pages 20-22
Keywords *Animal Feed; Animals; Feeding Behavior/physiology; Female; *Food Preferences; Horses/*physiology; Male
Abstract Preference trials were conducted with mature ponies. In Trial 1, oats were compared with oats plus sucrose. Four of six pony geldings selected oats plus sucrose, but one pony demonstrated a dislike for sucrose and one selected from the bucket on the right side regardless of content. Oats, maize, barley, rye and wheat were compared in Trial 2 using six mature pony mares. Oats were the preferred grain, with maize and barley ranking second and third respectively. Wheat and rye were the least preferred. Even though the ponies demonstrated preference, the total intake at a given meal was not greatly depressed when only the less palatable grains were fed. In Trial 3, pony mares selected a diet containing 20 per cent dried distillers' grain and 80 per cent of a basal mixed diet of maize, oats, wheat bran, soybean meal, limestone and molasses over 100 per cent basal mixed diet, but selected the basal diet over diets containing 20 per cent blood meal, beet pulp or meat and bone meal and 80 per cent basal diet. They did not differentiate against diets containing 20 per cent alfalfa meal or 10 or 5 per cent meat and bone meal when the diets were compared to the basal mixed diet.

Title Self-control revisited: Some factors that affect autoshaped responding Type Journal Article
Year 1985 Publication (down) Behavioural Processes Abbreviated Journal Behav. Process.
Volume 10 Issue 1-2 Pages 77-85
Keywords
Abstract Pigeons were exposed to autoshaping procedures under which 50% of red key illuminations were followed by 9-sec food deliveries, and 50% of blue key illuminations were followed by 3-sec food deliveries. When all key illuminations were 6 sec, pigeons preferred the red stimulus. Subsequent manipulations demonstrated that preference could be shifted to the blue stimulus by either increasing the duration of the red stimulus or imposing a delay interval between the offset of that stimulus and food delivery. A final experiment demonstrated that, in two of three subjects, preference for key illuminations associated with longer, but delayed, food deliveries generally increased as the duration of all key illuminations was lengthened. These results, obtained under conditions where keypecking had no programmed consequences, are similar to those previously observed under procedures involving a positive response-food dependency.

Title Grouped sequential exploitation of food patches in a flock feeder, the feral pigeon Type Journal Article
Year 1985 Publication (down) Behavioural Processes Abbreviated Journal Behav. Process.
Volume 11 Issue 1 Pages 39-52
Keywords
Abstract Feral and laboratory flocks of rock doves ( ) show a pattern of grouped sequential exploitation when simultaneously presented with two dispersed, depleting patches of seed. This behavior contrasts with the ideal free distribution pattern shown when patches are small and concentrated. Grouped sequential exploitation consists of two phases: all pigeons first land together and feed at one patch, then leave one by one for the other patch. Departure times of individuals for the second patch are correlated with feeding rate at patch 1, which is in turn correlated with position in the dominance hierarchy. The decision to switch from patch 1 to patch 2 improves individual feeding rates in all cases, but is done slightly later than it should according to optimal foraging theory.

Title Nursing behaviour and maternal aggression among Welsh ponies (Equus caballus) Type Journal Article
Year 1985 Publication (down) Applied Animal Behaviour Science Abbreviated Journal Appl Anim Behav Sci
Volume 14 Issue 1 Pages 11-25
Keywords
Abstract Nursing behaviour and related aggression of mare-foal pairs was studied from birth (n = 21) to 24 weeks of age (n = 15) of the foal. Foals exhibited a decreasing length and frequency of nursing as they grew older. Mares rarely aggressed against their foals during nursing in the foal's first 4 weeks of life, but did so increasingly through Weeks 13-16, after which the rate of aggression during nursing decreased. Mares terminated nursing primarily by moving away, and were most likely to do so during the foal's first 4 weeks of life. They became gradually less likely to do so as the foal grew older. It was concluded that mares sometimes flex their hind limb on the side opposite the foal during nursing in order to conserve energy in a situation in which they would be remaining still anyway. There was no difference between colts and fillies in the frequency or duration of nursing or in the frequency with which their mothers aggressed against them or terminated nursing.

Title Sustenance and Symbol: Anthropological Studies of Domesticated Animals Type Journal Article
Year 1985 Publication (down) Annual Review of Anthropology Abbreviated Journal
Volume 14 Issue Pages 375-403
Keywords
Abstract INTRODUCTION Thinking about Animals For nearly as long as anything can be inferred about human cognition, paleoanthropologists and archaeologists believe humans have thought carefully about animals, about the “predominant characteristic” of each animal, and about those “contradictory elements” that make up humankind. This careful thought has had many outcomes, some scientific, others not. Among the scientific outcomes in the 19th century was evolutionary thinking about the causes and consequences of domestication, including Charles Darwin's study (32) of the mechanics of human (artificial) selection of domesticated animal and plant population characteristics. In the 20th century, theoretical refinements and the painstaking collection of empirical data have led to studies of such disparate phenomena as the physical consequences of keeping pets (12); the spread of antibiotic-resistant bacteria as a result of feeding antibiotics to livestock (117); and the evolutionary consequences of milkdrinking (99). Speculation about the origins of human-animal interaction is not the exclusive province of scientists: religions and storytellers alike customarily try to account for the beginnings of human-animal interaction. Genesis does so
