Improving Nutritional Properties And Extractability Of Pea Proteins For Human Consumption Via Fungal Bioprocessing, Camille Massmann
Improving Nutritional Properties And Extractability Of Pea Proteins For Human Consumption Via Fungal Bioprocessing, Camille Massmann
Electronic Theses and Dissertations
Yellow peas are a rich source of protein and phytochemicals. Peas are compatible with many diets restricted by sensitivities, allergies, or personal choice. As a result, peas are gaining popularity in food markets, despite the challenges they present. The biggest challenges for pea proteins in food markets are high content of fiber, starch, and saponins. These components cause processing challenges and create undesirable textures and bitter flavors. Pea proteins are typically extracted with alkaline extraction or air classification methods which result in 80% and 50% protein products respectively. With low protein purity, these products are not competitive with other, more …
Biodegradable Cellulose Films As Alternatives To Plastics, Cecilia Wambui Wanjuu
Biodegradable Cellulose Films As Alternatives To Plastics, Cecilia Wambui Wanjuu
Electronic Theses and Dissertations
Plastics are versatile and have desirable packaging characteristics such as flexibility, durability, and affordability. The production of plastics has increased over the years resulting in concerns about their single-usage and disposal. Since plastics are nonbiodegradable, they have been associated with detrimental health impacts due to the leaching chemicals from the landfills and their accumulation in the natural and marine environment. Cellulose obtained from agricultural residues is a viable substitute because of its low density, biocompatibility, biodegradability, low toxicity, and a strong and stiff structure. However, the extraction of cellulose has been less exploited because of its insolubility in water and …
Identification And Genomic Characterization Of Candidate Starch And Lactate Utilizing Bacteria From The Rumen Of Beef Cattle, Venkata Bandarupalli
Identification And Genomic Characterization Of Candidate Starch And Lactate Utilizing Bacteria From The Rumen Of Beef Cattle, Venkata Bandarupalli
Electronic Theses and Dissertations
The rumen functions as an anaerobic fermentation chamber where microbial communities ferment feedstuffs into SCFAs. These SCFAs are critical to the ruminant host since they fulfill 70% of its energy requirements. In intensive management systems, ruminants are fed with grain-rich diets, which contain high levels of starch that help meet the energy demands of high producing animals. When grain-based diets are fed to ruminants, ruminal amylolytic and lactate metabolizing bacteria predominate. Grain overload can cause rapid production and accumulation of lactate, resulting in proliferation of amylolytic bacteria and death of lactate metabolizing bacteria. Consequently, high lactate levels result in a …
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 …
Effects Of Small Intestinal Starch Digestion And Dietary Lipid On Efficiency Of Nitrogen Use In Cattle, Ethan J. Blom
Effects Of Small Intestinal Starch Digestion And Dietary Lipid On Efficiency Of Nitrogen Use In Cattle, Ethan J. Blom
Electronic Theses and Dissertations
The objective of this research was to determine the effects of increases in energy available for gain from increased small intestinal starch digestion (SISD) and dietary lipid source and amount on the efficiency of N use in cattle. Five ruminally, duodenally, and ileally cannulated steers were placed in a 5 × 5 Latin square. Each received duodenal infusion of 1.5 ± 0.08 kg/d raw cornstarch and either 0, 30.9 ± 0.59, 62.4 ± 1.16, or 120.4 ± 3.39 g/d Glu, or 387.9 ± 17.47 g/d casein. Casein increased (P = 0.05) SISD. Similarly, greater duodenal Glu linearly (P = 0.02) …
Analysis Of Starch Branching Enzyme 1 (Sbe1) Gene In Maize, Abiskar Gyawali
Analysis Of Starch Branching Enzyme 1 (Sbe1) Gene In Maize, Abiskar Gyawali
Electronic Theses and Dissertations
A previous study revealed a quantitative trait locus (QTL) in maize on the short arm of chromosome 5 (5S) for endosperm amylose content. In that original study, both low and high amylose parental lines, H99ae and GEMS-0067 respectively, were homozygous recessive for amylose extender 1 (ae1) and the polymorphism responsible for this QTL was additive (semi-dominant). Located within the QTL interval is starch branching enzyme 1 (sbe1), which makes it a candidate gene. In order to test whether a polymorphism in sbe1 is the source of this QTL, we crossed a plant homozygous for ae1 and sbe1-Mu onto a …
Study Of The Effect Of Feeding Highly Digestible Corn Based Calf Starter On The Growth Performance Of Calves, Shruti Srivastava
Study Of The Effect Of Feeding Highly Digestible Corn Based Calf Starter On The Growth Performance Of Calves, Shruti Srivastava
Electronic Theses and Dissertations
New corn hybrids have been developed by Masters Choice (MC) that vary in energy density and starch digestibility. These MC hybrids have lower starch densities due to an altered starch structure, which allows for greater ruminal and intestinal starch digestion. The altered starch structure of these new hybrids results in reduced feed manufacturing costs (i.e., grinding). Thirty (30) 1 to 3 d old (40.6 ± 1.72 kg) Holstein heifer calves were randomly assigned to 1 of 2 calf starters to measure growth performance of Holstein heifer calves through 8 weeks of age. Treatments were: 1) Hard starch (HS) corn calf …
