The Influence Of Spore-Forming Microorganisms On The Quality And Functionality Of Cultured Dairy Products, Dipakkumar Mehta
The Influence Of Spore-Forming Microorganisms On The Quality And Functionality Of Cultured Dairy Products, Dipakkumar Mehta
Electronic Theses and Dissertations
Spore formers are observed as the common spoilage-causing microflora in milk and dairy products. Their spore-forming ability increases their survivability during heat treatment which leads to their presence in a final product. Spore-forming bacteria have ability to produce many types of spoilage-causing enzymes which are potential to influence quality and functionality of the final product. Many researchers have studied the ability of spore formers to induce a spoilage in various dairy products but as per our knowledge, their spoilage-causing activities are not described in a detail for cultured dairy products. In our first objective, we have studied the ability of …
Effect Of Exogenous Amylase And Protease On Ruminal Metabolism, Nutrient Digestibility, Rumen Microbiome, And Lactation Performance Of Dairy Cows Fed Freshly Ensiled Corn Silage Based Diets, Lauren Kaye Shearer
Effect Of Exogenous Amylase And Protease On Ruminal Metabolism, Nutrient Digestibility, Rumen Microbiome, And Lactation Performance Of Dairy Cows Fed Freshly Ensiled Corn Silage Based Diets, Lauren Kaye Shearer
Electronic Theses and Dissertations
The objective of this study was to examine the effects of feeding exogenous amylolytic and proteolytic enzymes on lactation performance of dairy cows fed freshly ensiled corn silage-based diets. We hypothesized that the addition of these enzymes would improve nutrient utilization and consequently lactation performance. Thirty-six Holstein cows [15 multiparous and 15 primiparous; DIM = 132 ± 48 and 6 cannulated (3 multiparous and 3 primiparous; DIM = 164 ± 50] were blocked by milk yield, DIM, parity, and body weights and used in a 9 wk randomized complete block design study.. Treatments were a 40% (DM basis) corn silage …
Strategies To Improve Calf Performance: Improving Water Quality, Feeding Microbially-Enhanced Soy Protein, And Supplementing Condensed Whey Solubles, Nirosh Dias Senevirathne
Strategies To Improve Calf Performance: Improving Water Quality, Feeding Microbially-Enhanced Soy Protein, And Supplementing Condensed Whey Solubles, Nirosh Dias Senevirathne
Electronic Theses and Dissertations
Six experiments were conducted for this dissertation research to evaluate strategies to improve growth performance and health of calves. Growth performance, nutrient utilization, and health effects were evaluated when calves were offered water treated with reverse osmosis system (RW), fed starter pellets supplemented with microbially-enhanced soy protein (MSP) or supplemented condensed whey solubles (CWS). The first two experiments were conducted to determine drinking preference, growth performance, and health of dairy calves offered RW or by a municipal water treatment plant (MW), compared with local untreated well water (WW). First a sequential elimination study was conducted to observed drinking preference of …
Evaluation Of Carinata Meal In Dairy Heifer Feeding Programs, Karla Rodriguez-Hernandez
Evaluation Of Carinata Meal In Dairy Heifer Feeding Programs, Karla Rodriguez-Hernandez
Electronic Theses and Dissertations
The main purpose of this body of research was to evaluate carinata meal as a feedstuff for dairy heifers and lay the foundations for its future evaluation in lactating dairy cow diets. This research focused on evaluating the taste preference of carinata meal compared with other oilseeds meals and distillers dried grains with solubles (DDGS). Despite containing glucosinolates, carinata meal was preferred similarly to canola meal, had greater preference compared to camelina meal, and less preference compared to the other meals. Next, we used a limit-feeding strategy in two different feeding studies, to determine the effect of feeding carinata meal …
Evaluation Of Dietary Phytochemicals As Rumen Modifiers In Lactating Dairy Cows, Sonia Rodriguez Jimenez
Evaluation Of Dietary Phytochemicals As Rumen Modifiers In Lactating Dairy Cows, Sonia Rodriguez Jimenez
Electronic Theses and Dissertations
Phytochemicals such as tannins included in dairy cow nutritional programs, as a natural feed additive, promise to improve rumen bypass protein and consequently reduce the feeding cost by decreasing the amount of CP needed in the ration. Additionally, if tannins are fed along with high quality protein sources, this could improve the AA profile reaching the small intestine and potentially improving health and performance of dairy cows. The black pepper, specifically its alkaloid piperine, is a nontoxic, natural dietary compound with a broad range of physiological activity. Lactating dairy cows ingesting these phytochemicals (tannin extracts and black pepper) will potentially …
