An Analysis Of Dairy Farm Financial Efficiency And Price Expectations In Seedstock Bull Markets, Seth H. Ingram
An Analysis Of Dairy Farm Financial Efficiency And Price Expectations In Seedstock Bull Markets, Seth H. Ingram
Masters Theses
The first thesis chapter employs two single-stage data envelopment analysis (DEA) models under varying returns to scale assumptions to provide technical efficiency estimates for 26 dairy farms in Tennessee, Kentucky, and North Carolina participating in the UT Dairy Gauge program. These analyses reveal how efficiently farms utilize inputs (cows, feed, labor, forage) to generate farm income relative to other sample farms. Under the assumption of constant returns to scale (CRS) 7 farms are estimated to be technically efficient, while 13 farms display comparative efficiency under an assumption of variable returns to scale (VRS). No …

Tall fescue (Lolium arundinaceum Schreb) is the most prevalent forage in the Mid-south United States due to its observed hearty nature and ability to withstand heavy grazing. This is due to a symbiotic relationship with an endophytic fungus (Neotyphodium coenophialum). This fungus produces ergot alkaloids, which can bind to many adrenergic, serotonergic, and dopaminergic receptors. One of the primary functions of dopamine is to inhibit prolactin response. Decreased growth, reproduction, lactation, and depressed serum prolactin concentrations are commonly observed in beef cattle grazing endophyte-infected tall fescue. These symptoms are collectively referred to as fescue toxicosis, and …
