Effects Of Toxic Fescue Exposure On Vaginal Microbial Communities Of Crossbred Beef Cows, Abby Ratton
Effects Of Toxic Fescue Exposure On Vaginal Microbial Communities Of Crossbred Beef Cows, Abby Ratton
Animal Science Undergraduate Honors Theses
The consumption of toxic fescue by beef cattle results in several adverse physiological effects such as reduced reproductive success, severe vasoconstriction resulting in hoof sloughing, low body condition scores, hyperthermia, decreased prolactin levels, and reduced hair shedding. The purpose of this study is to characterize bacterial community of the reproductive tract as a potential predictor for toxin exposure. One-hundred fall-calving crossbred cows were allocated to graze Toxic (Toxic: n=50) or Novel (Novel: n= 50) fescue pastures for five months (March-August). Treatments were blocked by sire breed (Charolais or Hereford) and by parity (first, second, third). Animals rotated pastures biweekly and …
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 …
