All checked.converted LD 24/1 Subcutaneous adipose tissues were biopsied in purebred Jersey (n=17), purebred Limousin (n=17) and reciprocal F1 JerseyxLimousin crossbred (n=33) calves at the age of 9 to 10 months. Triacylglycerol fatty acids were extracted and analysed for sex and breed differences. Heterosis, additive and maternal variances were estimated. All calves were pasture-fed in a single management group and biopsied from the same anatomical site. Heifer calves had significantly higher proportions of palmitoleate, total mono-unsaturated fatty acids, desaturation index and lower stearate than steer calves. Significant breed differences were observed in that Limousin calves had the highest proportions of palmitate and total saturated fatty acids, whereas Jersey calves had the most palmitoleate and desaturation index. Dominance effects were evident in the proportions of palmitate, stearate, desaturation and elongation enzyme indices due to the observed highly significant heterosis effect. Myristate, palmitate and total saturated fatty acids were considered heritable due to the observed highly significant additive genetic effect. 2000-04-01 published Journal of Animal Physiology and Animal Nutrition 83 2 106-112 10.1046/j.1439-0396.2000.00257.x UNSPECIFIED TRUE 0931-2439 http://www.blackwell-synergy.com.ezproxy.utas.edu.au/doi/full/10.1046/j.1439-0396.2000.00257.x Cundiff, L.
