title: [Identification of the optimal requirement of growing animals for polyunsaturated fatty acids].
abstract: Data obtained from studying eight groups of animals of a growing age showed their food rations to ensure proper growth and development when they contain optimal amounts of all food ingredients, including polyunsaturated fatty acids. Therefore, the fatty component in the food rations of test animals should contain both animal and vegetable fats, the latter comprising quantitatively 15 to 25 per cent of diurnal fat allowance. Such an amount of vegetable oil fully provides the rattlings with polyunsaturated fatt acids in a proportion comprising 4.3-5.8 per cent of the diurnal calorific value of the ration. For this reason, in investigations involving animal tests, or experimental substantiation of various problems pertaining to baby alimentation the authors recommend to use in feeding rattlings rations balanced in all the ingredients, including also the fatty acids composition.
