7-OILS is the most complex and richest commercially available oil preparation for pigeons and ornamental birds. It contains six most valuable vegetable oils and cod liver oil. Unsaturated fatty acids in the preparation (omega-3, omega-6 and omega-9) strengthen blood vessels, clear veins, facilitate blood circulation and increase the strength of the heart muscle contraction. This is very important to pigeons, considering the effort required for long-distance flying. Moreover, OILS-7 improves calcium absorption, strengthens joints and makes them more flexible, and moisturises the skin and feathers. Given during the moulting period, it imparts flexibility and resilience to new feathers – the properties which are very important in flying. Unsaturated fatty acids as well as numerous vitamin E isomers are also very effective in reducing vulnerability to bacteria and allergens, purifying the organism and improving immunity.
