Empirical prediction of organic matter digestibility in grasses, legumes and their mixtures from dairy farms in Atlantic Spain

Grassland Science, EarlyView.
Abstract This study characterized the chemical composition and organic matter digestibility (OMD) of herbage from commercial dairy farms in Galicia (NW Spain), a humid‐temperate Atlantic region, and developed empirical prediction equations for OMD based on routine wet‐chemistry traits.

Population Differentiation and Polygenic Selection in the Finnish Ayrshire Cows Selected on Genomic Information

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT The Finnish Ayrshire cattle belong to the Nordic Red breeds. The basis of selection in Nordic Red breeds shifted from traditional pedigree‐based breeding values to genomic breeding values between 2011 and 2014. Joint genetic evaluation and admixture among the Nordic Red breeds have led to the formation of a composite Nordic Red population ...

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.

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
