  • Proximate Factors Influencing Cat Behavior, Cognition, and The Human-Cat Bond

    Creator:
    Vitale, Kristyn R.
    Abstract:
    The domestic cat is one of the world’s most popular companion animals. However, to date much remains to be learned about cat behavior and the cat-human relationship. To examine the influence of proximate factors on cat behavior and the human-cat bond, three studies were undertaken. Study 1 directly measured the...

  • The Effects of Animal Interactions on Zookeeper Attachment and Possible Implications for Animal Welfare

    Creator:
    Koktas, Cemal
    Abstract:
    Human-animal relationships, emerging as an aftermath of human-animal interactions, have been increasingly investigated in recent years. It is possible to see the results of the effects of these relationships on both human and animal welfare. This study predicted that caretakers with hands-on contact with their zoo animals would have significantly...

  • The effect of rubberized flooring on Asian elephant behavior in captivity

    Creator:
    Meller, Camie L.
    Abstract:
    An experiment was designed to determine the effects of a poured rubber flooring substrate on the behavior of captive Asian elephants. Additionally, room utilization was evaluated in a series of seven rooms used for indoor housing. These seven rooms were divided into two observation areas, the Front observation area which...

  • Effect of prepartum anionic supplementation on periparturient feed intake and behavior, health and milk production

    Creator:
    DeGroot, Michael Alan
    Abstract:
    Our objectives were to determine if dietary cation-anion difference (DCAD) and source of anions influence periparturient feed intake and milk production, and to characterize feeding behavior of dairy cattle during the transition period. Diets differed in DCAD (cationic or anionic) and anionic supplement (BioChlor®, Fermenten®, or anionic salts), and were...

  • Factors affecting prolactin secretion in the African elephant

    Creator:
    Bechert, Ursula S.
    Abstract:
    Prolactin (PRL) is a peptide hormone that is involved in a number of diverse physiologic roles, particularly with respect to reproduction, including: influencing sexual and parental behaviors, onset of puberty, regulation of seasonal reproduction, follicular maturation, ovulation, luteinization and corpus luteum (CL) function, steroidogenesis, mammary gland development and lactation, testicular...

  • Factors influencing diet composition of beef cattle grazing mixed conifer mountain riparian areas

    Creator:
    Darambazar, Enkhjargal
    Abstract:
    Two trials were conducted to evaluate changes in the quantity, quality, and moisture of available forage in the pasture, and shrub utilization by cattle during a 30-d late summer grazing period (Trial 1) and the effect of cow age (experience) on grazing distribution and diet composition (Trial 2) in mountain...

  • Effect of nutrition on reproductive performance of young female mink

    Creator:
    Polonen, Ilpo Juhani
    Abstract:
    Two distinct experiments were conducted. Experiment 1 was conducted to investigate the effects of nutritional conditioning and flushing as a means of improving reproductive performance of female mink. In Exp. 2, vegetable oil and corn syrup were fed during lactation to ascertain whether this nutritional regimen would improve growth of...

  • The relationship of estradiol to embryo-maternal interactions in the llama

    Creator:
    Powell, Susan A.
    Abstract:
    In the first experiment, estradiol production was measured in cultured embryos collected on Days 7, 9, 11, 13 and 15 post-mating. Estradiol was detected in Day 7 embryos and production increased approximately 50-fold (P<0.05) in medium recovered from Day 13 compared to Day 11 embryos and was greatest (P<0.05) from...

  • Genetic and environmental variation in production components of purebred and crossbred ewes

    Creator:
    Nawaz, Mohammad, 1957-
    Abstract:
    Coopworth sheep, a newly available genotype, were compared with other genotypes in two trials to assess cumulative lamb and wool production and contributing components related to survival, reproduction and growth, and for the effects of ewe body weight on reproductive traits. In a third trial, various genotypes generated in the...

  • Role of post-translational modifications to lens proteins in cataract formation

    Creator:
    Kim, Yung Hae
    Abstract:
    Cataract is a leading cause of blindness throughout the world, yet the fundamental biochemical causes are unknown. A rodent model of the biochemical processes is selenite cataract. This cataract shows some of the features of human cataracts such as increased lens calcium, proteolysis of proteins, and insolubilization leading to lens...
