METHODS OF BIOLOGICAL EVALUATION OF FEEDS FOR DOGS

Abstract

Veterinary experts at drawing up feed rations for dogs should choose food that is well eaten, and have the necessary caloriesin view of its workload. It is necessary to take into account the energy requirement depending on the dog›s weight, sex, age and constitution of the animal, the physiological state (intrafamilial, lactation), and other factors. 100 g of feed should contain from 300 to 350 kcal of metabolizable energy, 25-30 % of crude protein (for dogs aged two years) and 15-20 % of crude protein (for dogs over two years), 3.5 % of crude fat (sometimes to 10 %, with obligatory consideration linoleic acid content, based on ration). Quantity of crude fiber should not exceed 2.4 %, although its presence is necessary for digestion as ballast. Cellulose is not digested in the dog as well as starch and many other polysaccharides. Practical rations in 100 g must contain 280-300 kcal of metabolizable energy, 20-25 % of crude protein, crude of fat 5%, 4% of crude fiber. Quantity of such diet per day is determined from the rate of 3-5 % of the live weight of the animal.
