The Resilient Dairy Genome Project (RDGP) is an international large-scale applied research project that aims to generate genomic tools breed more resilient dairy cows. In this context, improving feed efficiency and reducing greenhouse gases from a high priority. inclusion of traits related (e.g., dry matter intake [DMI]) or methane emissions [CH
The lifetime production of 7,655 cows with known age at first calving and a total 27,118 parity records from 301 purebred Blonde d'Aquitaine herds were used to demonstrate the economic benefits 2 yr calving. Ages ranged 20 48 mo, divided into 5 groups, starting early 27 mo up late 40 mo. information was gathered data sets, one for only primiparous second all cows. traits analyzed in this study grouped as functional, linear type, traits. Functional interval, ease, number calvings. Skeletal,...
This study evaluates two potential scenarios for including methane (CH4 ) emissions in the breeding objectives of beef cattle, using Spanish population Blonde d'Aquitaine as a case study. First, CH4 were included cost shadow carbon price 1.22€/CH4 kg (0.044€/CO2 kg) (carbon tax scenario). In other scenario, quota was applied, optimizing per unit product. The current production system used benchmark scenario (Scenario 1). economic value calculated under all bioeconomic model that translated...
A bio-economic model was developed for estimating economic values use in improving profitability a large national beef cattle population from birth to slaughter. Results were divided into fattening costs, production costs and income. Economic derived 17 traits two regions, mature weight (-0.43 € -0.38 €/+1 kg of live weight), age at first calving (-0.13 -0.11 €/+1d), interval (-1.06 -1.02 last (0.03 0.03 mortality 0-48 h (-5.86 -5.63 €/1% calves per cow year), pre-weaning (-5.96 -5.73 €/+1%...
Livestock will face an important challenge within the next decade to cope with objective of cut by 30% methane emissions, as agreed in COP26. This study summarises latest genetic parameter estimates between methane, dry matter intake, microbiota composition, and production body traits Spanish dairy cattle. We evaluated expected progress after including into breeding goal under different scenarios. Under current trend cow population size, it is only possible achieve if included a large weight...
