Effect of Breed on the Level of the Nutritional and Health-Promoting Quality of Semimembranosus Muscle in Purebred and Crossbred Bulls

Animals, 2020
Meat from commercial breed cattle are very often used to crossbreed with dairy breeds. The effect of heterosis is most evident when crossbreeds are genetically different from each other.

Minimal Erythema Dose Determination in Holstein Friesian Cattle [PDF]

Frontiers in Veterinary Science, 2021
Cattle on pasture are continuously exposed to solar UV radiation, which has been associated with biological effects such as sunburn, photosensitization, squamous cell carcinoma, and cutaneous vitamin D3 production. The minimal erythema dose (MED) required to produce first-degree sunburn (erythema) is poorly researched in cattle.

A new Robertsonian translocation in Holstein-Friesian cattle [PDF]

Genetics Selection Evolution, 1997
Une nouvelle translocation robertsonienne dans la race Prim'Holstein. Une nouvelle translocation robertsonienne a ete mise en evidence chez une vache de race Holstein. La coloration en bandes GTG nous a permis d'identifier les chromosomes impliques dans la translocation. Il s'agit des chromosomes 19 et 21.

An evaluation of production efficiencies among lactating Holstein-Friesian, Jersey, and Jersey × Holstein-Friesian cows at pasture [PDF]

Journal of Dairy Science, 2009
The objectives of this study were 1) to investigate production and energetic efficiencies among lactating dairy Holstein-Friesian (HF), Jersey (J), and Jersey x Holstein-Friesian (F(1)) cows over a total lactation at pasture and 2) to measure the associations among efficiency variables and performance traits.
