Implanting Effects On Performance, Carcass Characteristics And Reproductive Parameters In Intact Beef Males, Shirley J. Gordon
Electronic Theses and Dissertations
The research presented herein was designed to determine the effects of post-weaning implanting on performance, carcass characteristics, hormonal profile and reproductive parameters.
Nutritional Factors Modifying Fatty Liver Hemorrhagic Syndrome In Caged Laying Hens, Chandi C. Rakshit
Nutritional Factors Modifying Fatty Liver Hemorrhagic Syndrome In Caged Laying Hens, Chandi C. Rakshit
Electronic Theses and Dissertations
Three experiments each with two phases were conducted to study the effect of different levels of distillers dried grain (DDG), fat, oats and a mixture of oats and DDG on Fatty Liver Hemorrhagic Syndrome (FLHS) in caged laying hens. The second phase of each experiment was conducted by force-feeding the same diets used in the first phase at 120% of their normal intakes. This produces FLHS and thereby permits studying the effect of diets. During the force-feeding period of the third experiment, serum estradiol levels of hens from each treatment and each type of feeding were measured to study the …
A Comparison Of High-Performance Short-Duration And Repeated-Seasonal Grazing Systems, Jerry David Volesky
A Comparison Of High-Performance Short-Duration And Repeated-Seasonal Grazing Systems, Jerry David Volesky
Electronic Theses and Dissertations
Six replications of l-herd 16-subunit High-Performance Short-Duration (HPSDG) and Repeated-Seasonal (RSG) (May-Sep.) grazing system treatments were compared during 1983 and 1984 at the Cottonwood Range and Livestock Research Station located in western South Dakota. Calves and lambs were allotted to the experimental pastures in sets approximately equal on an animal unit basis. Animal numbers were adjusted with put-and-take sets to attain planned forage levels for each cycle of rotation in HPSDG and comparable end of season forage use levels in both treatments. The HPSDG system was operated with four cycles of rotation that had 1, 2, 2 and 3 occupation …
Inhibition Of Psychrotrophic Bacterial Growth In Refrigerated Milk By Addition Of Carbon Dioxide, Robert Francis Roberts
Inhibition Of Psychrotrophic Bacterial Growth In Refrigerated Milk By Addition Of Carbon Dioxide, Robert Francis Roberts
Electronic Theses and Dissertations
The advent of on-farm refrigerated storage for raw milk in the late 1940's and its subsequent adoption by North American dairyman 'during the next 20 years essentially eliminated spoilage of milk by lactic acid bacteria. However, refrigeration does not prevent growth of all microorganisms present in raw milk (9, 33, 51, 52, 54, 55). Many microorganisms capable of growth at refrigeration temperatures, termed psychrotrophic bacteria, are present as normal contaminants in raw milk supplies. For purposes of clarity, psychrotrophic microorganisms have been defined as microorganisms capable of growth at 7°C or below regardless of their optimum growth temperature (9). Milk …
Lactational And Systemic Responses To The Supplementation Of Protected Methionine In Soybean Meal Diets, Daniel J. Illg
Lactational And Systemic Responses To The Supplementation Of Protected Methionine In Soybean Meal Diets, Daniel J. Illg
Electronic Theses and Dissertations
The high producing dairy cow requires a complex balance of protein and energy. Microbial protein provides a substantial amount of the amino acids absorbed by the small intestine. High production rates cannot be attained with microbial protein as .the sole source of amino acids. The ten classical essential amino acids are required for milk protein synthesis. Increasing the amount of available amino acids to the mammary gland has improved casein production, indicating substrate availability as a controlling factor to milk protein synthesis. A major portion of the nitrogen component of milk is derived from free plasma amino acids. Uptake by …
