A Comparative Analysis Of The Nutrient Composition And Digestibility Of California Perennial And Annual Grasses At Four Stages Of Growth, Elaina Cromer

Master's Theses and Project Reports

Beef products represent the fourth largest agricultural commodity in the state of California, valuing more than $3 billion from 2013 to 2015 (CDFA, 2016) and procure 90% of the income for the range livestock industry (FRAP, 2003). Forages found on California’s coastal, desert, foothill, and mountain ranges are the basis of the state’s beef cattle industry. Understanding their nutritional quality of these forages is important for their effective use (George et al., 2001a; Waterman et al., 2014). The objectives of this research were to investigate the nutritional characteristics, and in situ digestbilities in Angus beef cattle, of common ...

Cost Of Feed Per Pound Of Gain In Cal Poly's Dairy Calves, Kayle Anna Phelan

Agricultural Education and Communication

California is ranked one of the top five states in the United States for dairy production. It produces approximately 40 billion pounds of milk per year for US production. California’s dairy industry is not only the largest milk producer in the nation, but it is also the most financially prominent in the agricultural industry. This industry lead is purely because of its careful management practices. The way calves are raised depend on the resources used, the natural environment present, and the operation of the dairy farm. Essentially, there are numerous ways to care for a cow and calf. However ...


The Recovery Of Protein From Egg Yolk Protein Extraction Granule Byproduct, Irene Jennifer Kaufman Jun 2017

The Recovery Of Protein From Egg Yolk Protein Extraction Granule Byproduct, Irene Jennifer Kaufman

Master's Theses and Project Reports

In addition to proving an excellent source of nutrients, eggs are used in the food, cosmetic, and biotechnology industries for their rheological and bioactive properties. Much of the potential for the added value is in individual components of the egg, rather than the whole egg. At low speed centrifugation, yolk separates into two distinct fractions—granules and plasma. It is becoming increasingly popular in the industry to remove the plasma fraction of the egg yolk to use for its livetins, particularly immunoglobulin Y, leaving behind a granule by-product (“yellow cake”). Previous research has shown potential added-value from the granule fraction ...
