  Title Ingestive behavior Type Journal Article
  Year 1990 Publication The Veterinary clinics of North America. Equine practice Abbreviated Journal Vet Clin North Am Equine Pract  
  Volume 6 Issue 2 Pages 319-337  
  Keywords Animals; Eating/*physiology; Feeding Behavior/*physiology; Horses/*physiology  
  Abstract In summary, horses spend 60% or more of their time eating when grazing or when feed is available free choice. Grasses are their preferred food, but they supplement the grass with herbs and woody plants. Sweetened mixtures of oats and corn are the most preferred concentrate. Horses can increase or decrease the time spent eating and amount eaten to maintain caloric intake. Their intake is stimulated by drugs such as diazepam and by the presence of other horses. Horses stop eating when gastric osmolality increases; increases in plasma osmolality, protein, and glucose accompany digestion. Foals eat several times an hour and begin sampling solid food at the same time that their dam is eating. Several areas of particular importance to the equine industry have not been investigated. These areas include the effect of exercise on short- and long-term food intake and the influence of reproductive state on the feeding of mares.

  Title The representation of social relations by monkeys Type Journal Article
  Year 1990 Publication Cognition Abbreviated Journal Cognition  
  Volume 37 Issue 1-2 Pages 167-196  
  Keywords Animals; Cercopithecus aethiops/*psychology; Concept Formation; *Dominance-Subordination; Female; Macaca fascicularis/*psychology; Male; *Social Behavior; *Social Environment  
  Abstract Monkeys recognize the social relations that exist among others in their group. They know who associates with whom, for example, and other animals' relative dominance ranks. In addition, monkeys appear to compare types of social relations and make same/different judgments about them. In captivity, longtailed macaques (Macaca fascicularis) trained to recognize the relation between one adult female and her offspring can identify the same relation among other mother-offspring pairs, and distinguish this relation from bonds between individuals who are related in a different way. In the wild, if a vervet monkey (Cercopithecus aethiops) has seen a fight between a member of its own family and a member of Family X, this increases the likelihood that it will act aggressively toward another member of Family X. Vervets act as if they recognize some similarity between their own close associates and the close associates of others. To make such comparisons the monkeys must have some way of representing the properties of social relationships. We discuss the adaptive value of such representations, the information they contain, their structure, and their limitations.

  Title Effect of indoor residual spraying of DDT and bendiocarb on the feeding patterns of Anopheles pseudopunctipennis in Mexico Type Journal Article
  Year 1990 Publication Journal of the American Mosquito Control Association Abbreviated Journal J Am Mosq Control Assoc  
  Volume 6 Issue 4 Pages 635-640  
  Keywords Animals; Anopheles/*physiology; *Carbamates; Cattle; *Ddt; Ecology; Enzyme-Linked Immunosorbent Assay; Feeding Behavior/*drug effects; Horses; Humans; Insect Vectors; Insecticide Resistance; *Insecticides; Mexico; *Phenylcarbamates; Seasons  
  Abstract Intense and persistent use of DDT for malaria control has increased resistance and induced exophilic behavior of Anopheles pseudopunctipennis. An evaluation of bendiocarb and DDT to control this species in Sinaloa, Mexico, showed that, in spite of DDT-resistance, both insecticides produced similar effects. Feeding patterns were analyzed to explain these results. Resting mosquitoes were collected over the dry and wet seasons. Anophelines were tested in an ELISA to determine the source of the meals. The human blood index (HBI) ranged from 3.3 to 6.8% in DDT- and from 12.7 to 26.9% in bendiocarb-sprayed houses. Irritability and repellency in DDT-sprayed houses could explain the reduced HBI. In contrast, bendiocarb produced higher mortality. These effects could have affected different components of the vectorial capacity and similarly reduced malaria.

  Title Variation in conformation of Swedish warmblood horses and conformational characteristics of elite sport horses Type Journal Article
  Year 1990 Publication Equine Veterinary Journal Abbreviated Journal Equine Vet J  
  Volume 22 Issue 3 Pages 186-193  
  Keywords Age Factors; Analysis of Variance; Animals; *Breeding; Female; Forelimb/anatomy & histology; Hindlimb/anatomy & histology; Horses/*anatomy & histology/physiology; Least-Squares Analysis; Male; Physical Conditioning, Animal; Regression Analysis; Sex Characteristics  
  Abstract The variation in conformation of 356 Swedish Warmblood horses is described, using a quantitative method of measuring horses. Thirty-three of the horses were elite dressage horses, 28 were elite showjumpers, 100 were riding school horses and 195 were unselected four-year-olds. Most horses had a long body form. The average height at the withers was 163.4 cm. Sixty per cent of the horses had a bench knee conformation, 50 per cent had a toe-in conformation of the forelimbs and 80 per cent had outwardly rotated hind limbs. The majority of these deviations were mild or moderate. Conformation was influenced by sex and age. Mares were smaller and had longer bodies and shorter limbs. The elite dressage horses and showjumpers had larger hock angles and more sloping scapulas than other horses. The showjumpers also had smaller fetlock angles in the front limbs. It is suggested that the larger hock angles among the elite horses may be because hocks with small angles are more prone to injury, and because small hock angles may negatively influence the ability to attain the degree of collection necessary for good performance in advanced classes.
