Prediction Of Mozzarella Cheese Yield From Milk Composition, Hamzah M. Abu-Tarboush

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to develop and evaluate several formulas which predict Mozzarella cheese yield from fat and protein content of milk and moisture content of cheese. During a one month period, 107 samples of milk and cheese were collected at Olympia Cheese Company, Olympia, Washington. Milk samples were analyzed for fat and protein content. Cheese samples were analyzed for fat, protein and moisture content.

Three models were derived to predict the yield of Mozzarella cheese. The three models were statistically fitted to the data by applying the Gauss-Newton non-linear least squares method of iteration. The differences among the three …

The Effect Of Rain Leaching On Field Dried Alfalfa Hay Yield And Lamb Production From The Hay, John M. Kaykay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A 2 x 3 x 2 factorial arranged split plot experiment was used to determine the decrease of dry matter yield from field-dried alfalfa hay caused by the application of a measured quantity of artificial rain (sprinkling irrigation). The three hay treatment factors were (1) alfalfa hay was cut at late vegetative and early bloom stage of maturity and (2) leached by 0, 5 mm or 20 mm of artificial rain applied by sprinkling and (3) sprinkled in the swath, 24 or 48 hours after cutting.

Changes in dry matter yield were not significantly (P < .05) related to stage of maturity of forage, level of artificial rain applied or the time of application of artificial rain. There were no significant interactions for dry matter yield. The non-significant results were probably due to the variability of the alfalfa stand among the specific areas harvested for each treatment and insufficient replications to control the variability.

Forty-eight lambs were fed for …
