Supplementing beef cattle diets with brown seaweed affects coprophagous beetles' dung use

Agricultural and Forest Entomology, EarlyView.
Supplementing beef cattle diets with brown seaweed reduced the attractiveness of dung for a common dung beetle (Onthophagus nuchicornis). Dietary supplementation with brown seaweed appeared to reduce the proportion of major males in the F1 generation.

Environmentally adjusted productivity growth and shadow prices for dairy farms

Canadian Journal of Agricultural Economics/Revue canadienne d'agroeconomie, EarlyView.
Abstract We estimate the environmentally adjusted productivity growth and shadow price for Ontario dairy farms. We use an input‐oriented directional distance function and farm‐level data from 2000 to 2020. First, we find that while GHG emissions per cow increase with higher milk yields, emission intensity decreases as milk yield per cow increases.

The hole in the doughnut: Formalizing and testing a key model of degrowth

Contemporary Economic Policy, EarlyView.
Abstract Degrowth scholars often claim that capitalism generates social and ecological imbalances, as captured by Kate Raworth's leading doughnut model. We formalize this model using social and environmental indices and measure imbalances using their coefficient of variation.

Genetic Parameters of Methane Emission, Feed Efficiency, Feeding Behaviour, and Growth Traits in Beef Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Climate change has intensified the need to reduce greenhouse gas emissions, particularly methane (CH4) from enteric fermentation. Genetic selection has emerged as a promising mitigation strategy; however, studies on Bos taurus indicus , especially Nellore cattle, remain limited.

Genetic Relationships Between Residual Gain and Economically Important Traits in Nellore Cattle

Journal of Animal Breeding and Genetics, EarlyView.
ABSTRACT Sustainable beef production requires identifying animals with superior feed efficiency to reduce environmental impact and production costs. This study aimed to estimate heritability and genetic correlations between residual gain (RG) and growth, reproductive, carcass and feed efficiency traits in Nellore cattle.
