متن کاملCASE STUDY: Performance of Lactating Jersey and Jersey- Holstein Crossbred Versus Holstein Cows in a Wisconsin Confinement Dairy Herd
The objective of this trial was to measure performance of paired pens of lactating Jersey and Jersey-Holstein crossbred (JX) vs. Holstein (H) cows over a year in a Wisconsin confinement dairy herd. Average daily milk yield of JX was 5.5 kg/ cow less than H, whereas average milk fat and true protein percentages were 0.61 (4.26 vs. 3.65%) and 0.19 (3.05 vs. 2.86%) percentage units, respectively, ...
