Time Series Forecast Analysis In Wholesale Broiler Markets, Christopher R. Sims

Theses and Dissertations

In 2016 the chicken industry provided nearly 1.2 million jobs, 68 billion dollars in wages, 313 billion dollars in economic activity and 24 billion dollars in government revenue (John Dunham & Associates, Inc., 2016). Broiler production has changed dramatically from the early 90’s to the turn of the 21st century. Technological advancements, continuous improvements, production efficiencies and industry changes have made the industry the global market it is today. The poultry industry is an extremely volatile market with prices constantly fluctuating in response to input price volatility and demand and supply changes. These changes are often driven by world economic conditions which impacts the roughly 20% of U.S. production that is exported. Due to these variations, accurate forecasting of poultry prices is difficult. Economic modeling is complex at best; this paper examines a comparison between vector autoregression (VAR) and autoregressive (AR) techniques. Urner Barry average monthly northeast wholesale poultry parts price data was used for this research. Parts analyzed are; drumstick (DRUM), jumbo boneless skinless breast tender out (BSBTO), leg quarter (LQ), thigh (THIGH), small wing (SMWING), jumbo wing (JMWING), tender (TENDER) and whole bird without giblets weighing 2 ¼ lbs. (WOG). This modeling will focus on the ...


Productivity Measures In Beef Cows And Calves Following A Single Subcutaneous Injection Of Extended-Release Eprinomectin, Claire Andresen Jan 2017

Productivity Measures In Beef Cows And Calves Following A Single Subcutaneous Injection Of Extended-Release Eprinomectin, Claire Andresen

Graduate Theses and Dissertations

The effect of a single subcutaneous injection of extended-release eprinomectin for parasite control on cow/calf performance was evaluated in a pair of studies. In the first study, a fall-calving Angus herd was utilized. Mature cows were treated with either extended-release eprinomectin (EPR) or a conventional injectable anthelmintic (CONV). Cows treated with EPR had better maintenance of BCS through calving and into breeding. Subsequent pregnancy rates were greater for EPR than CONV cows. Furthermore, calves from EPR dams were younger at weaning, but had greater weaning weights than calves from CONV dams. From the same fall-calving Angus herd, replacement heifers ...
