Effect Of Processing On The Composition And Microstructure Of Buttermilk And Its Milk Fat Globule Membranes, Pierre Morin, Rafael Jiménez-Flores, Yves Pouliot
Effect Of Processing On The Composition And Microstructure Of Buttermilk And Its Milk Fat Globule Membranes, Pierre Morin, Rafael Jiménez-Flores, Yves Pouliot
Dairy Science
The effect of cream pasteurization on the composition and microstructure of buttermilk after pasteurization, evaporation and spray-drying was studied. The composition of milk fat globule membrane (MFGM) isolated from buttermilk samples was also characterized. Pasteurization of cream resulted in higher lipid recovery in the buttermilk. Spray-drying of buttermilk had a significant effect on phospholipid content and composition. After spray-drying, the phospholipid content decreased by 38.2% and 40.6%, respectively in buttermilk from raw or pasteurized cream when compared with initial buttermilks. Pasteurization of cream resulted in the highest increase in whey protein recovery in MFGM isolates compared with all other processing …

Influence Of Free-Stall Base On Tarsal Joint Lesions And Hygiene In Dairy Cows, W. K. Fulwider, T. Grandin, D. J. Garrick, T. E. Engle, W. D. Lamm, N. L. Dalsted, B. E. Rollin
Influence Of Free-Stall Base On Tarsal Joint Lesions And Hygiene In Dairy Cows, W. K. Fulwider, T. Grandin, D. J. Garrick, T. E. Engle, W. D. Lamm, N. L. Dalsted, B. E. Rollin
Housing and Confinement of Farm Animals Collection
The objective was to quantify the incidence of tarsal lesions and level of hygiene by stall bed type. Cows were scored on 100 dairies from Wisconsin, Minnesota, Indiana, Iowa, and New York in the fall and winter. Thirty-eight dairies used rubber-filled mattresses (RFM), 27 had sand beds, 29 had waterbeds, and 6 used compost packs (CPk). Stocking density, stall dimensions, bedding amount, bedding frequency, and type of bedding were recorded. One pen of early-lactation multiparous cows on each dairy was scored based on injury of the tarsal joints at the lateral and medial surfaces and tuber calcis at the dorsal, …
A Comparison Of Pyronin Y-Methyl Green Stain And Methylene Blue Stain For Somatic Cell Count In Sheep Milk, Emily Mirek, Stacey O’Donnell
A Comparison Of Pyronin Y-Methyl Green Stain And Methylene Blue Stain For Somatic Cell Count In Sheep Milk, Emily Mirek, Stacey O’Donnell
Senior Honors Projects
Somatic cell count is a key method used to evaluate the quality of milk in today’s growing dairy sheep industry. Somatic cells are body cells, primarily the white blood cells, found in a milk sample. If an infection such as mastitis is present, the number of somatic cells in the milk increases (Gonzalo, et al. 1992). Producers routinely perform somatic cell counts on cow and goat milk. For dairy cattle in the United States, the somatic cell count can not exceed 750,000 cells per milliliter, for commercial milk. For dairy goats the accepted limit is 1,000,000 cells per mL of …

Characterization Of Dairy Milk House Waste Water In Kentucky, Anshu Singh, Czarena L. Crofcheck, Gail M. Brion
Characterization Of Dairy Milk House Waste Water In Kentucky, Anshu Singh, Czarena L. Crofcheck, Gail M. Brion
Biosystems and Agricultural Engineering Faculty Publications
This study focuses on characterization of milk house waste water from eight different farms in Kentucky. The farms were separated into three groups based on the number of cows: small (20-30), medium (30-60), and large (over 60 cows). Samples were collected once a month from four farms and twice a month from the remainder. Samples were analyzed for chemical, biochemical, and microbiological characteristics. Results indicated a large and significant variation in the chemical and microbiological characteristics between the farms. Farm size had a significant effect on the nutrient content of the waste water. Though samples exhibited seasonal variation, there was …

Flavor Partition And Fat Reduction In Cheese By Supercritical Fluid Extraction: Processing Variables, Jessica L. Yee, Hany Khalil, Rafael Jiménez-Flores
Flavor Partition And Fat Reduction In Cheese By Supercritical Fluid Extraction: Processing Variables, Jessica L. Yee, Hany Khalil, Rafael Jiménez-Flores
Dairy Science
Developing low-fat cheese with flavor to match that of full-fat cheese has been a challenge in the dairy industry. The objective of this investigation was to develop lower fat Cheddar and Parmesan grated cheese using supercritical fluid extraction (SFE) and characterize its flavor profile comparative to a full-fat product. Specifically, enabling flavor compound partition between the matrices of cheese and extracted lipids. Carbon dioxide (CO2) was the supercritical fluid for fat extraction. Extraction took place in a 500 mL SFE vessel using 100 g of grated cheese. Fractional factorial design was utilized to investigate two levels of treatment …

Use Of Exogenous Fibrolytic Enzymes To Enhance In Vitro Fermentation Of Alfalfa Hay And Corn Silage, Jong-Su Eun, K. A. Beauchemin, H. Schulze
Use Of Exogenous Fibrolytic Enzymes To Enhance In Vitro Fermentation Of Alfalfa Hay And Corn Silage, Jong-Su Eun, K. A. Beauchemin, H. Schulze
Animal, Dairy, and Veterinary Science Faculty Publications
Two in vitro experiments were performed to identify promising exogenous fibrolytic enzyme products (EFE) and optimum dose rates (DR) for improving the degradation of alfalfa hay and corn silage. The relationship between enzymatic activity and fermentation responses was examined to identify optimum formulations. In experiment 1, 5 EFE containing mainly endoglucanase and xylanase activities, with different ratios between the 2 activities, were assessed at a DR of 0.7, 1.4, and 2.1 mg/g of DM forage. Milled alfalfa hay or corn silage was incubated in an in vitro batch culture with buffer, ruminal fluid, and EFE. Gas production (GP) was measured …
Enhancing In Vitro Degradation Of Alfalfa Hay And Corn Silage Using Feed Enzymes, Jong-Su Eun, K. A. Beauchemin
Enhancing In Vitro Degradation Of Alfalfa Hay And Corn Silage Using Feed Enzymes, Jong-Su Eun, K. A. Beauchemin
Animal, Dairy, and Veterinary Science Faculty Publications
A series of in vitro fermentation experiments was performed to assess the effects of 4 feed enzyme products (FE) that varied in enzymatic activities on the degradation of alfalfa hay and corn silage. The FE contained a range of endoglucanase, exoglucanase, xylanase, and protease activities, and a range of dose rates (DR) was used. The objective of the study was to identify effective formulations and optimum DR, and to establish if combining FE would further improve fiber degradation. For alfalfa hay, quadratic increases in gas production and degradation of dry matter (DM) and fiber were observed for all FE, with …
