Development Of Arkansas Net Energy Equation, Katie Hilton
Development Of Arkansas Net Energy Equation, Katie Hilton
Graduate Theses and Dissertations
The modern broiler is growing at a rapid rate generating tremendous amounts of heat. A sensitive Net Energy (NE) system is needed to measure body heat production (HP) generated primarily by daily maintenance and synthesis and degradation of myofibrillar and sarcoplasmic protein. The first two chapters present evaluation of the classic way to calculate NE versus a new methodology; the Arkansas NE (Ark NE) system, with birds from two genetic lines fed diets with different AA content or different ME content in two different environmental temperatures.
Utilizing together the Net Energy maintenance (NEm), determined from indirect calorimetry, and Net Energy …
Performance Of The Producer Accumulator In Corn And Soybean Commodity Markets, Chad Te Slaa
Performance Of The Producer Accumulator In Corn And Soybean Commodity Markets, Chad Te Slaa
Electronic Theses and Dissertations
This research quantifies risk reduction and performance of the producer accumulator contract in corn and soybean markets. To quantify performance, we use three alternative theoretical pricing models to estimate historical producer accumulator contract specifications in corn and soybean markets. We then compare the performance of the producer accumulator to eight alternative agricultural marketing strategy portfolios that are also used in new generation grain contracts. The performance measures we compare are: average bushel price that would be received by the producer, daily portfolio risk, and the Sharpe ratio. The period we examine performance was between 2008 and 2017. We investigate performance …
Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Evaluation Of Low-Tannin Grain Sorghum In Broiler Chicken Diets, Samantha Aniecia Shelton
Graduate Theses and Dissertations
Research trials were conducted to evaluate the effects of different levels of dietary grain sorghum on broiler live performance, carcass yield and shank (leg) and breast skin coloring. Iso-caloric diets were formulated where sorghum replaced corn at rates of 0% (control), 20, 40, 60, 80 and 100% for a total of 6 diets. For each of the two trials, 1500 Cobb 500 male broiler chicks were randomly allocated to 60 pens with 25 birds per pen (10 pens/diet) and grown to 46 days for the first research trial and 41 days for the second. There were no differences (P>.05) …
