Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
Influence Of "Added" Whey Protein Isolate On Probiotic Properties Of Yogurt Culture Bacteria And Yogurt Characteristics, Luis Alfonso Vargas Lopez
LSU Master's Theses
Consumers are becoming conscious of their diet, increasing protein intake and avoiding carbohydrates and fats. Whey proteins have branch chain amino acids responsible for muscle building. Whey protein isolate (WPI) contains more than 90% protein. The effect of incremental addition of WPI on probiotic characteristics of pure cultures and cultures in yogurt and yogurt characteristics are not known. The hypothesis was that “added” WPI will influence the characteristics of yogurt culture bacteria in pure form and in yogurt. The objectives were: to determine the influence of added WPI on (1) acid and bile tolerance, growth and protease activity of pure …
Effects Of Probiotics And Yeast Culture On Rumen Development And Growth Of Dairy Calves, Jennifer Marie Laborde
Effects Of Probiotics And Yeast Culture On Rumen Development And Growth Of Dairy Calves, Jennifer Marie Laborde
LSU Master's Theses
Forty-eight calves (heifers n=20, bulls n=28) were randomly assigned one of four dietary treatments which included no additive (C); the yeast culture Saccharomyces cerevisiae (YC); the probiotics Bacillus lichenformis and Bacillus subtilis (P); and both yeast culture and probiotics (YCP). Calves were administered treatments from day 2 to 56 in starter and from day 57 to 84 in grower diets. Body weights were measured at birth and weekly thereafter until day 112 of age. Wither and hip heights were measured weekly. Feed intake, water intake, and fecal scores were recorded twice daily until day 56. Rumen fluid was collected on …
