Predictive formulae for goat cheese yield based on milk composition
Prediction of the yield and quality of different types of cheeses that could be produced from a given type and/or amount of goat milk is of great economic benefit to goat milk producers and goat cheese manufacturers. Bulk tank goat milk was used for manufacturing hard, semi-hard and soft cheeses (N= 25, 25 and 24, respectively) to develop predictive formulae of cheese yield based on milk compos...
متن کاملMultiple Logistic Regression and Model Fit Multiple Logistic Regression Just as in OLS regression, logistic models
Multiple Logistic Regression Just as in OLS regression, logistic models can include more than one predictor. The analysis options are similar to regression. One can choose to select variables, as with a stepwise procedure, or one can enter the predictors simultaneously, or they can be entered in blocks. Variations of the likelihood ratio test can be conducted in which the chi-square test (G) is...
متن کاملEffect of pasture species on milk yield and milk composition
One IO-day experiment in autumn 1994 then four lo-day experiments throughout the 1994195 lactation in a complete Latin square investigated the effect of pasture species on yield, composition and total colour of milk from dairy cows. Treatments were Grasslands Kopu white clover (Trifolium repens L.), Yatsyn1 perennial ryegrass (L&urn perenne L.), Grasslands Kahu timothy (Phfeum pratense L.) and ...
متن کاملMilk Composition and Cheese Yield
When the Wisconsin dairy sheep industry got started in the mid 1990s, cheesemakers had to get accustomed to a whole new source of milk. All were familiar with cow milk and some were familiar with goat milk. However, sheep milk was much more concentrated with about twice as much fat and 40% more protein that cow or goat milk. They also found that sheep milk responded differently in the cheese ma...
متن کاملAn Optimum Regression Model to Estimate Economic Values for Milk Yield, Milk Yield Persistency and Calving Interval in Dairy Cattle
Emphasis on milk yield (MY) as well as milk yield persistency (MYP) and calving interval (CI) is necessary to achieve more sustainable productionin dairy cattle. Therefore the main objective of this study was to find an optimum regression model to estimate economic values for MY, MYP and CI.Using a deterministic bio-economic model, seventyfiveproduction states differing mainly in MY, MYPand CIw...
