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 …

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 …
