Quantitative trait loci for organ weights and adipose fat composition in Jersey and Limousin back-cross cattle finished on pasture or feedlot
Summary A QTL study of live animal and carcass traits in beef cattle was carried out in New Zealand and Australia. Back‐cross calves (385 heifers and 398 steers) were generated, with Jersey and Limousin backgrounds. This paper reports on weights of eight organs (heart, liver, lungs, kidneys, spleen,...

A QTL study of live animal and carcass traits in beef cattle was carried out in New Zealand and Australia. Back‐cross calves (385 heifers and 398 steers) were generated, with Jersey and Limousin backgrounds. This paper reports on weights of eight organs (heart, liver, lungs, kidneys, spleen, gastro‐intestinal tract, fat, and rumen contents) and 12 fat composition traits (fatty acid (FA) percentages, saturated and monounsaturated FA subtotals, and fat melting point). The New Zealand cattle were reared and finished on pasture, whilst Australian cattle were reared on grass and finished on grain for at least 180 days.

A QTL study of live animal and carcass traits in beef cattle was carried out in New Zealand and Australia. Back‐cross calves (385 heifers and 398 steers) were generated, with Jersey and Limousin backgrounds. This paper reports on weights of eight organs (heart, liver, lungs, kidneys, spleen, gastro‐intestinal tract, fat, and rumen contents) and 12 fat composition traits (fatty acid (FA) percentages, saturated and monounsaturated FA subtotals, and fat melting point). The New Zealand cattle were reared and finished on pasture, whilst Australian cattle were reared on grass and finished on grain for at least 180 days. For organ weights and fat composition traits, 10 and 12 significant QTL locations (P < 0.05), respectively, were detected on a genome‐wide basis, in combined‐sire or within‐sire analyses. Seven QTL significant for organ weights were found at the proximal end of chromosome 2. This chromosome carries a variant myostatin allele (F94L), segregating from the Limousin ancestry, and this is a positional candidate for the QTL. Ten significant QTL for fat composition were found on chromosomes 19 and 26. Fatty acid synthase and stearoyl‐CoA desaturase (SCD1), respectively, are positional candidate genes for these QTL. Two FA QTL found to be common to sire groups in both populations were for percentages of C14:0 and C14:1 (relative to all FAs) on chromosome 26, near the SCD1 candidate gene.</description><identifier>ISSN: 0268-9146</identifier><identifier>EISSN: 1365-2052</identifier><identifier>DOI: 10.1111/j.1365-2052.2010.02058.x</identifier><identifier>PMID: 20477785</identifier><identifier>CODEN: ANGEE3</identifier><language>eng</language><publisher>Oxford, UK: Blackwell Publishing Ltd</publisher><subject>Adipose Tissue - chemistry ; Alleles ; Animals ; Australia ; Body Composition - genetics ; Cattle ; Cattle - genetics ; Chromosome Mapping - veterinary ; Chromosomes ; Crosses, Genetic ; fat composition ; Fatty Acid Synthases - genetics ; Fatty acids ; Fatty Acids - chemistry ; Female ; Genes ; Genomics ; Genotype ; Jersey ; Limousin ; Male ; Myostatin - genetics ; New Zealand ; organ ; Organ Size - genetics ; Phenotype ; QTL ; Quantitative Trait Loci - genetics ; Stearoyl-CoA Desaturase - genetics</subject><ispartof>Animal genetics, 2010-12, Vol.41 (6), p.589-596</ispartof><rights>2010 AgResearch Ltd, Animal Genetics © 2010 Stichting International Foundation for Animal Genetics</rights><rights>2010 AgResearch Ltd, Animal Genetics © 2010 Stichting International Foundation for Animal Genetics.</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c5328-c04a7bc22fe20ddc2c278d124f76b6fc2aae6913fbc0767042f0d4aebb564f453</citedby><cites>FETCH-LOGICAL-c5328-c04a7bc22fe20ddc2c278d124f76b6fc2aae6913fbc0767042f0d4aebb564f453</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fj.1365-2052.2010.02058.x$$EPDF$$P50$$Gwiley$$H</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fj.1365-2052.2010.02058.x$$EHTML$$P50$$Gwiley$$H</linktohtml><link.rule.ids>315,781,785,1418,27926,27927,45576,45577</link.rule.ids><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/20477785$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Morris, C.

A QTL study of live animal and carcass traits in beef cattle was carried out in New Zealand and Australia.
