Genetic diversity of bovine populations raised in Senegal [PDF]
This study revealed that the animals in Senegal's cattle breeding programmes show low genetic diversity. This is mainly explained by reproductive isolation and selection pressure. Abstract Background The Gobra zebu and N'dama taurine cattle breeds are important genetic animal resources for Senegal.

The contribution of a MOET nucleus scheme for the improvement of Guzerá (Bos indicus) cattle for milk traits in Brazil [PDF]
The Guzerá breed evolved from the introduction of breeds from India, mainly the Kankrej breed, into Brazilian livestock at the end of the 19th century. Guzerá adapted well to the climatic conditions of Brazil, where it is considered a dual-purpose breed ...

Genetic Diversity and Population Genetic Structure of a Guzerá (Bos indicus) Meta-Population [PDF]
The Brazilian Guzerá population originated from a few founders introduced from India. These animals adapted well to the harsh environments in Brazil, were selected for beef, milk, or dual-purpose (beef and milk), and were extensively used to produce ...

Qualidade da carne de bovinos superprecoces terminados em confinamento [PDF]
Avaliou-se a qualidade da carne de 10 bovinos F1 Guzerá-Nelore e 10 F2 Pardo Suíço-Guzerá-Nelore, inteiros, e abatidos precocemente. Na avaliação da carne, foi utilizado o músculo Longissimus dorsi. O delineamento experimental foi o inteiramente ao acaso.

Abstract Individual variation in milk fatty acid (FA) composition has been partially attributed to stearoyl‐CoA desaturase 1 (SCD1) gene polymorphisms in taurine breeds, but much less is known for Zebu breeds. This study investigated the phenotypic variation in milk FA composition, and the influence of SCD1 variants on this trait and on milk fat ...
