Signatures of positive selection in African Butana and Kenana dairy zebu cattle

PLoS ONE, 2018
Butana and Kenana are two types of zebu cattle found in Sudan. They are unique amongst African indigenous zebu cattle because of their high milk production.

Genetic diversity of BoLA-DRB3 in South American Zebu cattle populations

BMC Genetics, 2018
Bovine leukocyte antigens (BoLAs) are used extensively as markers of disease and immunological traits in cattle. However, until now, characterization of BoLA gene polymorphisms in Zebu breeds using high resolution typing methods has been poor.

Genetic variability of 10 microsatellite markers in the characterization of Brazilian Nellore cattle (Bos indicus)

Genetics and Molecular Biology, 2006
We assessed the polymorphism of 10 microsatellites in Brazilian Nellore cattle (Bos indicus) using a commercial multiplex system. Allele frequencies, polymorphism information content, heterozygosity and exclusion probability were calculated.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Parâmetros genéticos para a produção de leite de controles individuais de vacas da raça Gir estimados com modelos de repetibilidade e regressão aleatória Estimation of genetic parameters for test day milk records of first lactation Gyr cows using repeatability and random regression animal models

Revista Brasileira de Zootecnia, 2005
Registros individuais perfazendo 8.183 controles de produção de leite (PLC) de 1.273 primeiras lactações de vacas da raça Gir de rebanhos supervisionados pela ABCZ no período 1994/2000 foram utilizados para se estimar componentes de variância e ...

Production objectives, trait and breed preferences of farmers keeping N'Dama, Fulani Zebu and crossbred cattle and implications for breeding programs.

Animal, 2017
Many local livestock breeds in developing countries are being replaced by exotic breeds, leading to a loss of genetic resources. In southern Mali, for the past two decades, a trend towards increasing crossbreeding between the trypanotolerant N'Dama ...

Seasonality of fruiting phenology, hunting behaviour and taste preferences in Madagascar's Makira Protected Area

People and Nature, EarlyView.
Abstract For many people around the world, especially in Indigenous communities, seasonal changes affect the availability and desirability of different types of food. Assessing the relationship between seasonality, sociocultural preferences and hunting patterns is vital for understanding how these populations harness seasonal food production dynamics ...

Legacies of domestication, trade and herder mobility shape extant male zebu cattle diversity in South Asia and Africa

Scientific Reports, 2018
All tropically adapted humped cattle (Bos indicus or “zebu”), descend from a domestication process that took place >8,000 years ago in South Asia. Here we present an intercontinental survey of Y-chromosome diversity and a comprehensive reconstruction of ...

Embodied Narrations: Video Narrative Inquiry for Meaning‐Making of Learning Contexts

International Journal of Art &Design Education, EarlyView.
Abstract This text begins with the initial question of how we can narrate in a situated and meaningful way about the processes of teaching and learning, not to repeat what we imagine that we should say and already know, but to be truthful with respect to the issues that affect us and matter to us.
