Genetic and Phenotypic Correlations Among Growth, Disease Occurrence, and Reproductive Performance From Calf to Heifer in Girolando Dairy Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Girolando breed, a cross between Holstein (Bos taurus) and Gir (Bos indicus), is the primary choice for dairy production in Brazilian tropical regions, as it combines high productive potential with adaptation to the tropical environment.

A Transformation From Methane Concentration From Sniffers to Methane Production for Implementation in Breeding Programs and Comparison With Tier 2 Equation

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Reducing methane emissions from dairy cattle has gained considerable attention due to its dual benefits of improving feed efficiency and mitigating climate change. Consequently, phenotyping methane emissions in dairy populations has become increasingly important to enable direct genomic selection for lower methane emissions in breeding ...

Genome‐Wide Association Studies for Anogenital Distance and Linear Type Traits in Gir Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Although linear type traits have been under selection in the Dairy Gir cattle for the past three decades, there are few studies exploring genetic architecture for these traits. The aim of this study was to identify candidate genes for anogenital distance and linear type traits in the Gir breed. For this study, the body measures of rump length (

Between Autonomy and Dependency: The Territorialisation of Agroecology in the Colombian Peasant Reserve Zones

Journal of Agrarian Change, EarlyView.
ABSTRACT Peasant movements employ a spectrum of politico‐economic strategies for territorialising agroecology, ranging from autonomy to (inter)dependency. To substantiate this argument, I draw on qualitative fieldwork and historical analysis to examine the Colombian Peasant Reserve Zone movement's strategies for territorialising agroecology at both the
