Influence of pig substitution on milk yield, litter weights, and milk composition of machine milked sows.
This study was conducted to 1) determine milk yield of sows that were machine milked up to four times daily; 2) determine the effect of pig substitution on milk yield; 3) assess litter weight changes for sows that are milked; and 4) determine milk composition. Eight sows were milked four times daily to d 51 postpartum. Sows either maintained their own litter or had a week-old replacement litter...

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 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 ...
