If current food consumption patterns continue, the agriculture sector must provide significantly more food in the coming years from the available land area. Some livestock systems engage in feed–food competition as arable land is used for livestock

Effect of production quotas on economic and environmental values of growth rate and feed efficiency in sea cage fish farming.

Autor: M Besson, I J M de Boer, M Vandeputte, J A M van Arendonk, E Quillet, H Komen, J Aubin

Publikováno v: PLoS ONE, Vol 12, Iss 3, p e0173131 (2017)

In sea cage fish farming, production quotas aim to constrain the impact of fish farming on the surrounding ecosystem. It is unknown how these quotas affect economic profitability and environmental impact of genetic improvement. We combined bioeconomi

In fish farming, economic values (EV) of breeding goal traits are lacking, even though they are key parameters when defining selection objectives. The aim of this study was to develop a bioeconomic model to estimate EV of 2 traits representing produc

Prediction of ammonia emission from dairy barns using feed characteristics part 1: Relation between feed characteristics and urinary urea concentration

Autor: I J M, de Boer, M C J, Smits, H, Mollenhorst, G, van Duinkerken, G J, Monteny

Publikováno v: Journal of dairy science. 85(12)

Urinary urea concentration is an important predictor of NH3 emission from dairy barns. To reduce urinary urea concentration, accurate and precise prediction of urea concentration for different feeding regimes is a prerequisite. The objective of this
