The organizers and speakers have prepared this seminar with the hope that we can understand better the environmental impact of the dairy beef production and to debate how to improve it. Interpreting the data that measure the environmental impact is not as easy as we think, which are the critical points to have in mind when looking at those data ? Do studies support the hypothesis that beef produced from dairy beef has a lower impact compared with the beef produced from suckler cows? In the first part of the seminar, we hope to answer these questions.
In the second part we want to talk about strategies to reduce the environmental impact of dairy beef production as we are compromised to reduce it.

Researcher at IRTA's Sustainability in Biosystems Research Program since 2020. Martais an expert in the application of LCA to food products and agrosystems.
She is interested in quantifying and improving the environmental impact of agricultural and livestock management practices.
After finishing a degree in Environmental Sciences, Dr Ruiz obtained a Ph.D by the Department of Geography and Geology of University of Alcalá (“Influence of using cover crops in hillslope vineyards to control soil erosion”). Since then, she has gained extensive experience working both in university and consultancy, conducting research mostly related to agricultural and livestock sustainability. Currently, as a researcher at the Sustainability in Biosystems Group (IRTA), she is specializing in the application of Life Cycle Assessment (LCA) methodology, conducting LCA of different agricultural systems including different crops and animal products as well as LCA of different agricultural land management practices. She is interested in the environmental impact of agricultural practices, and the assessment of different management strategies for a more sustainable land use.

Mogens Vestergaard has 35 years of experience within cattle research at Aarhus University, formerly at the Danish Institue of Animal Science. He is currently holding a dual-position as senior scientist at Aarhus University in Foulum and as a chief scientist/advisor at SEGES in Aarhus. At Aarhus University he works in the Nutrition group in the Department of Animal Science with research within unweaned as well as transition calves, rearing of replacement heifers but most of all with any type of veal and beef production system. So, he has performed research with intensively-fed rosé veal calves, grazing young bulls, organically-reared beef x dairy cattle, and finish feeding of cull dairy cows. He studies nutrition-system interactions, animal performance, health-related aspects, carcass value and quality aspects. He has experience in use of sensors for assessing animal eating and ruminating behavior, automated milk-feeders and Insentec feed bins for recording individual feed intake. Besides that he teach and supervise PhD-, MSc- and BSc-students. At SEGES, he works in the team of Health and Production, and lead more applied projects which includes performing trials at private slaughter calf operations on subjects of immediate relevance for the veal and beef farmers. Recent projects included: Effects of extra water supply to calves; Effects of adjusting milk feeding level before and after shipping calves to beef producers; Effects of natural vitamin E in calf starter concentrates to assure vitamin E levels in blood post-weaning; Transition feed rations for rosé veal calves; Probiotics for unweaned and newly weaned calves; Improve colostrum feeding of calves
