In cow-calf operations the moment the heifer achieves her first pregnancy set up her future productivity. Although puberty itself is a yes-or-no condition, time to the event has a quantitative genetic basis and thus is suitable for genetic selection.

In bovine, there are significant differences among and within breeds in the time when bulls reach puberty. Reported data indicate that age at puberty has a strong genetic component and is a multigenic trait. However, despite significant advancements

Genetic markers have been used to assess the association of economically important traits with cattle under intensive feeding conditions; however, there is still the need to ascertain the usefulness of these markers under extensive production systems

Breed assignment has proved to be useful to control meat trade and protect the value of special productions. Meat-related frauds have been detected in China; therefore, 95 SNPs selected from the ISAG core panel were evaluated to develop an automated

Association of a region of bovine chromosome 1 (BTA1) with age at puberty in Angus bulls

Autor: Pilar Peral-García, M.E. Fernández, Juan Pedro Lirón, Alberto José Prando, A. Rogberg-Muñoz, Guillermo Giovambattista, Andrés Baldo

Publikováno v: Reproduction, fertility, and development.

Age at puberty is an important component of reproductive performance in cattle, so it is important to identify genes that contribute to the regulation of the onset of puberty and polymorphisms that explain differences between bulls. In a previous stu

Possible association of bovine chromosome 5 markers with growth and fat traits in Hereford cattle raised under extensive conditions

Bovine chromosome 5 has been widely studied because several QTLs have been detected there, in particular for growth and fat traits. Even though most of the beef is produced under pasture based conditions, only little research has focused on this kind

Since the 1990s several authors have envisaged the use of DNA to certify meat origin. Two major parameters must be assessed before a DNA based traceability protocol can be implemented in the food chain: (i) the information content of a DNA marker set

Animal markers assisted selection in South America: A point of view

Genetic identification has been continuously evolving during the last century. The recent development of whole-genome projects allowed the discovery and characterization of a large number of single nucleotide polymorphisms (SNP). A number of high-thr

Background: In bovines, there are significant differences within and among beef breeds in the time when bulls reach puberty. Although the timing of puberty is likely to be a multigenic trait, previous studies indicate that there may also be single ge
