Effects Of Management And Environmental Conditions On Antibiotic Resistance In Bacteria Associated With Swine, Patricia Cullen

Masters Theses

Weaned pigs (n=58) were challenged with nalidixic resistant Salmonella enterica serotype Typhimurium and separated into eight treatments to determine the effects of various environmental and management conditions on the development of antibiotic resistance among pathogenic and commensal bacteria. Apramycin sulfate was administered in the feed (150g/ton) two days postchallenge for a period of 14 days with the exception of one control group. Treatments included: control without apramycin (control-1); control with apramycin (control-2); and apramycin plus either cold stress, heat stress, overcrowding, intermingling, poor sanitation, and intervention with oxytetracycline (100 ug / ton). Treatments were applied 5 days post initial antibiotic …

The Effect Of Littermate Weight On Survival, Weight Gain, And Suckling Behavior Of Low-Birth-Weight Piglets In Cross-Fostered Litters, Barry N. Milligan, David Fraser, Donald L. Kramer

Ontogeny Collection

Objective: To determine whether low-birth-weight piglets show better survival, weight gain, and suckling behavior when grouped with other small piglets by cross-fostering.

Methods: We manipulated the number and size of foster littermates for low-birth-weight piglets in 31 small (eight or nine piglets) and 22 large (11 or 12 piglets) litters. Experimental litters were composed of four to six piglets of lowest birth weight and either four to six slightly heavier or four to six much heavier piglets from two combined litters.

Results: Low-birth-weight piglets raised with much heavier littermates had somewhat lower survival rates, but showed no tendency towards lower …
