Growth, productive performance, and udder health of crossbred Holstein x Simmental cows and purebred Holstein cows

Comparison of performance of Holstein and Holstein * Fleckvieh dairy cows for production, fertility and health

Production, reproduction, health, and growth traits in backcross Holstein × Jersey cows and their Holstein contemporaries.

A total of 648 purebred Holstein and 319 backcross Holstein × Jersey dairy cattle were compared for production, reproduction, health, linear type, and growth traits. Animals were born between 2003 and 2009 and were housed in the University of Wisconsin-Madison Integrated Dairy Facility. All animals had Holstein dams; lactating dams were mated to unproven Holstein sires to produce purebred (cont...

Blood metabolic profiles in Uruguayan Holstein and Uruguayan Holstein x New Zealand Holstein-Friesian dairy cows

Blood metabolic profiles were determined from 40 days prepartum to 60 days postpartum in Uruguayan Holstein (UH) (n = 13) and UH x New Zealand Holstein-Friesian first cross (UH-NZHF) (n = 13) cows with seven in each group experiencing their second lactation (L2) and six experiencing their third lactation (L3). Non-esterified fatty acids increased around calving and tended to be greater in UH-L3...

CASE 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, ...
