Evaluation Of Supplementing Brewer's Yeast To Lactating Dairy Cows, Taylor Christine Aubrey
Evaluation Of Supplementing Brewer's Yeast To Lactating Dairy Cows, Taylor Christine Aubrey
Electronic Theses and Dissertations
Probiotics have been used as effective, natural feed additives in the dairy industry to improve animal health and performance. Yeast product supplementation can be beneficial in the diet of lactating dairy cows by increasing feed efficiency, alleviating disease, and improving production performance under heat stress. Objectives of this study were to evaluate supplementing a concentrated brewer’s yeast in the ration of a lactating dairy cow by assessing milk yield and composition, blood metabolites, rumen fermentation, and feed intake and efficiency. We hypothesized that diets containing a concentrated brewer’s yeast supplement would increase milk and component yields, benefit rumen fermentation, and …
Response Of Dairy Cows To Dietary Starch Concentrations: Performance, Nutrient Digestion, And Gas Emissions, Juan Isidro Sanchez-Duarte
Response Of Dairy Cows To Dietary Starch Concentrations: Performance, Nutrient Digestion, And Gas Emissions, Juan Isidro Sanchez-Duarte
Electronic Theses and Dissertations
Three studies and a meta-analysis were conducted to determine the performance, nutrient digestion, and gas emissions of dairy cows fed diets with different starch concentrations (19 to 27% of DM). Study 1 evaluated the effects of reducing corn grain starch with non-forage fiber sources (NFFS, soybean hulls and beet pulp) in diets of soybean meal (SBM) or canola meal (CM). In study 1, reducing starch from 27 to 20% with soybean hulls and beet pulp had a negative effect on dry matter intake (DMI), milk yield and energy-corrected milk (ECM), regardless of the crude protein (CP) source. Those effects were …
The Effects Of A Blend Of Essential Oils On Rumen Efficiency Of Lactating Dairy Cows, Kali Linville
The Effects Of A Blend Of Essential Oils On Rumen Efficiency Of Lactating Dairy Cows, Kali Linville
Electronic Theses and Dissertations
The objective of this study was to evaluate the effects of SS a blend of commercially available essential oils (EO) on rumen microbial efficiency and kinetics, and consequently, effects on production parameters of dairy cows fed a low-starch diet and in vitro analysis of varying doses of SS on ruminal fermentation at different stages of lactation. The study consisted of two experiments, the in vivo Experiment 1, was conducted on a commercial robotic dairy in southwest Minnesota outfitted with two Lely Astronaut A4robotic milking units (Goter’s Clay & Dairy Equipment of MN, INC., Pipestone, MN). One hundred-seven Holstein cows were …
Effect Of Ultrasonication On Biofilm Forming Ability Of Common Dairy Sporeformers, Taghreed Almalki
Effect Of Ultrasonication On Biofilm Forming Ability Of Common Dairy Sporeformers, Taghreed Almalki
Electronic Theses and Dissertations
Sporeformers are common dairy contaminants, which are of a great concern to the dairy industry. Quality of dairy products is affected by these sporeformers such as Bacillus species, which are a significant cause of spoilage of dairy products. Thermal processes such as pasteurization have been used to inactivate pathogens, but some of the sporeformers and their endospores are resistant to such heat treatments. Beside thermal treatments, various new approaches are being developed to improve the quality of dairy products. Amongst these, ultrasonication is a promising non-thermal technique for the inactivation of thermoduric sporeformers and their endospores. Current study was carried …
Biofilm Formation By Common Dairy Sporeformers On Native And Modified Stainless Steel Surfaces, Shivali Jindal
Biofilm Formation By Common Dairy Sporeformers On Native And Modified Stainless Steel Surfaces, Shivali Jindal
Electronic Theses and Dissertations
Aerobic sporeformers can be traced in a variety of dairy products such as milk powders, evaporated milk, and canned products, which demonstrates their capability of resisting high temperature treatments such as pasteurization and Ultra high temperatures. These bacilli also actively attach to the stainless steel surfaces, consequently resulting in the formation of biofilms. Product quality as well as its safety is undesirably affected by the growth of these sporeforming bacteria. Therefore, creating an ideal environment for the processing of dairy products is a critical challenge for the dairy industry. Hence, the objective of this research was to analyze various surface …
