Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan Lichtenwalter
Impact Of Teat Order On Feed Consumption In Swine From Birth To Nursery, Callan Lichtenwalter
Animal Science Undergraduate Honors Theses
A relationship between teat order and feed consumption has been assumed in pigs, but no study has looked at this exact relationship. Pigs were observed shortly after birth to be in either a cranial, middle, or caudal teat positon. Growth performance data and active and total plasma ghrelin concentrations were analyzed at birth, weaning, and at the end of the nursery stage of production to see if a relationship with teat order was present. Further growth performance data were analyzed during different phases of the nursery stage. Overall, no effect of teat order was found on average daily gain, average …
Personality In California Sea Lions (Zalophus Californianus) And Harbor Seals (Phoca Vitulina): Methodological Convergence And Species-Specific Emotional Repertoires, Amber De Vere
Dissertations
Despite the wide acceptance of animal personality as a valid area of study, research on marine mammal personality remains remarkably scarce. What literature does exist predominantly focuses on bottlenose dolphins (Frick, 2016; Highfill & Kuczaj, 2007; Kuczaj, Highfill & Byerly, 2012; Lilley, de Vere, Yeatre & Kuczaj, 2018; Moreno, Highfill & Kuczaj, 2017). There is also strong evidence for individual differences in grey seals (Robinson et al., 2015; Twiss & Franklin, 2010; Twiss, Culloch & Pomeroy, 2011; Twiss, Cairns, Culloch, Richards & Pomeroy, 2012), and preliminary research has provided evidence of broad personality factors in pinniped species using behavioral coding …
The Effects Of Super-Dosing Phytase On Nursery And Grower Pigs, Joshua Paul Knapp
The Effects Of Super-Dosing Phytase On Nursery And Grower Pigs, Joshua Paul Knapp
Graduate Theses and Dissertations
To determine the effects of super-dosing on pigs fed phosphorous and calcium adequate or deficient diets (Experiment 1); the optimum level of corn express phytase (CEP, Experiment 2); and the effects of xylanase/phytase on growth performance (Experiment 3) in pigs fed reduce nutrient diets, weaned pigs were blocked with initial body weight (BW) and allotted to dietary treatments. Treatments were: Positive control (PC), P/Ca adequate diets (NRC 2012); Negative Control (NC), low P (-0.15%) and Ca (-0.12%), +0, 1000, and 4000 FTU/kg of CEP in both PC and NC (Experiment 1); PC, P/Ca adequate diets; NC, decreased P (0.15%) and …
Response Of Three Species Of Monkeys To Caregiver Use Of Species-Typical Behavior, Lillian Anna Stolar
Response Of Three Species Of Monkeys To Caregiver Use Of Species-Typical Behavior, Lillian Anna Stolar
All Master's Theses
Caregivers are a primary part of captive monkey environments. When addressing psychological well-being of captive nonhuman primates, social environment should be considered. Chimpanzees, gorillas, New World monkeys, and Old World monkeys responded positively to interactions with caregivers. Some species showed increased affiliative behaviors and decreased abnormal or self-directed behaviors after interactions. These studies showed that caregivers can affect the behavior of nonhuman primates. Caregivers are underutilized as a source of social interaction for captive nonhuman primates. Utilizing species-typical behaviors during interactions, caregivers and nonhuman primates can communicate and interact in different ways that may be beneficial to both caregiver and …
