Maternal Phylogenetics of Some Anatolian Cattle Breeds

Maternal Effects in Four Diverse Breeds of Cattle

Mitochondrial DNA variants of Podolian cattle breeds testify for a dual maternal origin

BACKGROUND Over the past 15 years, 300 out of 6000 breeds of all farm animal species identified by the Food and Agriculture Organization of the United Nations (FAO) have gone extinct. Among cattle, many Podolian breeds are seriously endangered in various European areas. Podolian cattle include a group of very ancient European breeds, phenotypically close to the aurochs ancestors (Bos primigeniu...

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...

Some preliminary observations on the susceptibility and resistance of different cattle breeds to Theileria parva infection.

Theileria parva-naïve Friesian (Bos taurus), Boran (Bos indicus) and Maasai Zebu steers (B. indicus) were infected with a T. parva sporozoite stabilate dose which had previously been shown to induce an estimated 50% mortality rate in Boran cattle. All the cattle developed patent infections with no significant differences in the length of the prepatent period to development of macroschizonts (P ...

Cattle Breeds: Extinction or Quasi-Extant?

Uniquely selected breeds bred over thousands of years of domestication in a wide range of environments have been declared extinct over the last century. Still more breeds are at risk of becoming extinct and the rate continues to accelerate. Assessing the current status and possible future dynamics of livestock breeds is therefore a critical step in the management of Animal Genetic Resources (An...
