All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah's cattle feeding industry was described by using both secondary and primary data. The primary data were collected through use of a personal interview survey.

Primary data were also collected in Idaho, while secondary data were used for Arizona, California and Colorado.

Intrastate analysis of feeding costs showed definite cost savings were achieved in all states through economies of size.

Interstate analysis of feeding costs showed Utah's larger capacity feedlots to be very competitive with larger capacity lots in other states.

1968 prices for both slaughter and feeder cattle were computed for each state. Prices in Utah were slightly lower …

Growth Of Eimeria Alabamensis From Cattle In Vitro And The Changes In Fine Structure Associated With Schizogony, J. Robert Sampson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Monolayer primary cultures of cells from bovine embryonic intestine (BEint), kidney (BEK), spleen (BES), and thyroid (BET) and cell line cultures of embryonic bovine trachea ( EBTr) and synovium (BESy)as well as established cell line cultures of Madin-Darby bovine kidney (MDBK), human intestine (Int 407), and Syrian hamster kidney (BHK-21) were inoculated with freshly excysted sporozoites of Eimeria alabamensis and observed for 4 days. Sporozoites penetrated all cell types during the first 24 hours in culture. Numerous intracellular sporozoites, trophozoites, and binucleate schizonts were seen in all cell cultures except Int 407. The best development occurred in BES and MDBK …
