Conservation of local Red cattle breeds by collaboration with a mainstream Red dairy cattle breed

Across breed multi-trait random regression genomic predictions in the Nordic Red dairy cattle.

The current study evaluates reliability of genomic predictions in selection candidates using multi-trait random regression model, which accounts for interactions between marker effects and breed of origin in the Nordic Red dairy cattle (RDC). The population structure of the RDC is admixed. Data consisted of individual animal breed proportions calculated from the full pedigree, deregressed proof...

Inbreeding in Danish dairy cattle breeds.

The purpose of this study was to monitor current and predict future rates of inbreeding in the Danish dairy breeds. Calves born from 1999 until 2003 and registered as Danish Holstein (1,883,983), Danish Jersey (336,966), or Danish Red (261,047) were reference populations. Average complete generation equivalent was approximately 7. For calves born in 2003, average inbreeding was 3.9, 3.4, and 1....

Kappa-casein Genotypic Frequencies in Russian Breeds Black and Red Pied Cattle

Casein is a family of milk proteins that exists in several molecular forms and is the main protein present inthe bovine milk. The B variant of bovine k-casein is reported to be favorable for quality and quantity of cheese derived from milk and considered to be included in breeding strategies of dairy cattle. Genotypes of72 Russian Black Pied and 80 Red Pied cows were determined for ...

The origin of Indonesian cattle and conservation genetics of the Bali cattle breed.

Both Bos indicus (zebu) and Bos javanicus (banteng) contribute to the Indonesian indigenous livestock, which is supposedly of a mixed species origin, not by direct breeding but by secondary cross-breeding. Here, the analysis of mitochondrial, Y-chromosomal and microsatellite DNA showed banteng introgression of 10-16% in Indonesian zebu breeds with East-Javanese Madura and Galekan cattle having ...
