DGAT1 K232A polymorphism in Brazilian cattle breeds.

Recent reports identified DGAT1 (EC 2.3.1.20) harboring a lysine to alanine substitution (K232A) as a candidate gene with a strong effect on milk production traits. Our objective was to estimate the frequency of the DGAT1 K232A polymorphism in the main Zebu and Taurine breeds in Brazil as well as in Zebu x Taurine crossbreds as a potential QTL for marker-assisted selection. Samples of 331 anima...

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....

Productivity and Efficiency of Cattle Breeds

The purpose of this report is to rank the most numerous beef cattle breeds which took pert in the National Beef Cattle Performance and Progeny Testing Scheme (PTS) for individual growth traits and some productivity and efficiency indices. Data from Progress Reports of the Scheme were re-analysed for this investigation. Some authors (Brown & Dinkel, 1982; McMorris & Wilton, 1986) hold the belief...
