It has been established that the fat from fat-tailed breeds is different from that found in thin-tailed breeds, in that the body fat has a lower melting temperature, is soft and oily and a translucent yellow whilst the tail fat is white and hard (more similar to fat found in thin tailed breeds of sheep). When put to the test, fatty acid p rofiles were very similar between Damara, Merino and Dorper lambs, all aside from the branched-chain fatty acid content. Branched-chain fatty acids are considered to be ‘bio-active compounds’ as there is evidence that they can improve intestinal health, especially in newborns, and may play a role in reducing cancer risk. The branched-chain fats in the Damara tail totalled 8.8% of total fat, but of this, 77% consisted of uncommon structural isomers (known as mono- and di-methyl branched fatty acids). Analysis revealed that some of these unusual branched-chain fatty acids were also present in Damara muscle , suggesting that as the animal’s feed was restricted Damara lambs were mobilising and using fat from their tails – an interesting and unique metabolic trait.

[ Google Scholar] [ CrossRef] Fat-tailed sheep are a unique type, consisting of many different breeds, all of which are characterised by a despot of fat either on the rump or in the elongated tail. This unique feature is thought to be an adaptation to the harsh, arid environment that they originate from, allowing the sheep to mobilise fat from the tail when conditions are challenging. This results in a unique lipid metabolism and extremely lean meat. The storage of fat on the rump/tail is also distinctive, containing high levels of unusual branched-chain fatty acids that may be beneficial in human health. The fat from fat-tailed sheep is important in Middle Eastern cooking and our diverse range of cultures in the UK means that there is now a demand for this fat and therefore a market for the breed. Fat-tailed sheep are well adapted to arid environments which may render them unsuitable for farming in the UK. A potential solution is the careful crossbreeding with local breeds that are better adapted to the local environment – recently this has been done in Angelsey, North Wales where an EIP funded project has produced purebred Damara lambs using embryo transfer and crosses with Lleyn ewes using AI. The lambs have thrived in the Welsh climate and have left the project with the first purebred and cross lambs and ewes. The group will now work on getting these unique lambs to market and developing the Damara Môn brand.

The fat-tail sheep is a hardy and unique type characterised by substantial fatty deposits located on the rump or in the elongated tail. Feng H, Yousuf S, Liu T, Zhang X, Huang W, Li A, et al.

It is fat accumulated in baggy deposits in the hind parts of a sheep on both sides of its tail and on the first 3–5 vertebrae of the tail. The weight of this part of a sheep's anatomy (for example, the sheep of the Hissar breed) may be up to 60kg (130lb). [1] These hind parts are used to accumulate fat for subsequent use during dry seasons, similar to a camel's humps. [2] [3]
