Genome-wide association study for methane emission traits in Danish Holstein cattle
Manzanilla-Pech, C.I.V.; Difford, Gareth Frank; Sahana, G.; Romé, H.; Løvendahl, Peter; Lassen, J. (Peer reviewed; Journal article, 2022)Selecting for lower methane emitting cows requires insight into the most biologically relevant phenotypes for methane emission, which are close to the breeding goal. Several methane phenotypes have been suggested over the ... -
Multitrait genomic prediction of methane emissions in Danish Holstein cattle
Manzanilla-Pech, Coralia Ines V.; Gordo, D.; Difford, Gareth Frank; Løvendahl, Peter; Lassen, Jan (Peer reviewed; Journal article, 2020) -
Phenotypic modeling of residual feed intake using physical activity and methane production as energy sinks
Olijhoek, Dana W.; Difford, Gareth Frank; Lund, Peter; Løvendahl, Peter (Peer reviewed; Journal article, 2020)Residual feed intake (RFI) is a measure of feed efficiency in dairy cattle. This study modeled phenotypic RFI of first- and second-parity Holstein and Jersey dairy cows within 9 lactation segments (consecutive segments of ... -
Predictive ability of host genetics and rumen microbiome for subclinical ketosis
Gebreyesus, Grum; Difford, Gareth Frank; Buitenhuis, Bart; Lassen, Jan; Noel, Samantha Joan; Højberg, Ole; Plichta, Damian R.; Zhu, Zhigang; Poulsen, Nina A.; Sundekilde, Ulrik K.; Løvendahl, Peter; Sahana, Goutam (Peer reviewed; Journal article, 2020)Subclinical metabolic disorders such as ketosis cause substantial economic losses for dairy farmers in addition to the serious welfare issues they pose for dairy cows. Major hurdles in genetic improvement against metabolic ...
