Modern dairy industry is not focused on milk yield alone but also on qualitative traits such as milk content. In this respect, the composition of milk proteins is of considerable importance for further processing, in particular for the suitability of cheese production. The kappa-casein gene affects several quality traits of milk , such as clotting time, heat stability, taste and cheese yield. It became evident that the B variant is particularly advantageous for further processing.
The different gene variants can be determined by genetic testing.
In the case of multiples, the foetal placentas are interconnected via vascular anastomoses which lead to an exposition to masculinzing factors and subsequent impaired development of the reproductive tract in the female twin. The virilisation can vary considerably. This hampers identification of infertile females by physical examination alone. However, molecular genetic testing enables clear diagnosis of the XX / XY chimerism in the infertile female.
Please note: Freemartin testing requires the submission of blood samples.
* Performed by partner laboratory
Please note: The test does not detect any genetic disposition which may result in Scurs and is validated for Bos Taurus, only.
Based on scientific knowledge, at least nine different mutations in the bovine myostatin gene are currently distinguished, all of which lead to muscular hypertrophy in cattle. Not all known mutations are common in all breeds of cattle affected by muscle hypertrophy.
Six mutations declared as disruptive (C313Y, nt419, E226X, nt821, E291X and Q204x) lead to muscle hypertrophy, higher birth weight and, as a result, difficult births, but also to an improved tenderness of the meat. The so-called missense variants, on the other hand, increase the degree of musculature, but reduce external and intramuscular fat and have no influence on the birth weight.
GeneControl is currently offering the test for the disruptive variant nt821. This mutation, which is genetically fixed in the white-blue Belgians breed, also occurs in the Piedmontese, Angus and Limousin breeds and is a mostly undesirable trait here.
