Feed and nutrition fat for raccoon dogs
In feed composition analysis, all substances that can be extracted with ether are collectively referred to as crude fat, which includes fat, glycerol and lipid compounds.
Fat is an essential component of the body. For example, the components of mitochondria and Golgi apparatus in germ cells are mainly phospholipids, there are a lot of lecithin and brain phospholipids in nerve tissue, and all kinds of fats in blood. The skin and coat contain a lot of neutral fat, phospholipids, cholesterol and wax.
Fat is not only the main source of heat energy for animals, but also the best form of energy storage. 1 gram of fat is completely oxidized in the body, which may produce about 39 kilojoules (9.3 kcal) of calories. It is 2.25 times higher than carbohydrates, and fat is also a good solvent for vitamin a, vitamin d, vitamin e, vitamin k and other good solvents. The absorption and transportation of these vitamins depend on fat.
Fatty acids are an important component of fat. It can be divided into two categories: saturated fatty acids and unsaturated fatty acids. The chemical properties of saturated fatty acids are stable, and the melting point of the fat is high and the iodization value is low. It is not easy to be oxidized and is in a solid state at room temperature. The higher the content of unsaturated fat is, the higher the chemical property and instability is, the higher the content of unsaturated fat is, the higher the melting point of unsaturated fat is, the easier it is to oxidize and deteriorate.
Necessary for the life activities of animals. However, if the extract can not be synthesized in large quantities, unsaturated fatty acids, called essential fatty acids, must be obtained from feed. Linolenic acid, linolenic acid and glycoletetraenoic acid are essential fatty acids in fur animal feed. Practice has proved that in the diet during the breeding period, not only protein should be paid attention to, but also fat should not be ignored. Fatty acids must be as important as essential amino acids.
Fat is very easy to oxidize and rancidity, and rancid fat does great harm to the body. Oxidative rancidity of fat is a chemical reaction during storage, which is characterized by obvious yellowing, bitterness and special odor of fat. Rancidity fat and decomposition products are very harmful to the health of raccoon dogs. Because they directly act on the mucous membrane of the digestive tract, causing inflammation of the whole small intestine, causing serious digestive disorders, rancid fat decomposition, destroying a variety of microorganisms in feed, and loss of appetite of young raccoon dogs. Slow growth or cessation, serious damage to skin health, abscess or rash. Reduce the quality of wool batches. Especially during pregnancy, raccoon dogs are more sensitive to rancidity fat, which will cause adverse consequences such as stillbirth, rotten fetus, weak litter and lack of milk of mother raccoon dog. Therefore, in the process of feed storage, special attention should be paid to prevent the oxidation and corruption of fat.

Feed formulation and blending of Meat Dogs
Meat dog feed is a reasonable combination of animal feed, plant feed and mineral feed. The nutrition standards in the feed are: protein 17% 25%, fat 3% 7%, fiber 3% 4.5%, carbohydrate 44% 49%, calcium 1.5% 1.8%, phosphorus 1.1% 1.2% and trace amounts of copper, chlorine, potassium, magnesium, manganese, cobalt, zinc, iodine and multivitamins. Feed formula: (1) artificial milk formula: 1 egg, 300 grams of concentrated bone and meat soup, 50 grams of baby cake powder, 2 fresh milk

Prevention and treatment of acute and chronic gastric perforation of raccoon dog
At present, the price of peel is on the rise, and some farmers are eager for quick success and quick profit and feeding blindly, resulting in an increasing incidence and mortality of gastric perforation. Here are some suggestions to share with the majority of colleagues and farmers. First, pay attention to observation, timely adjustment of feeding with the growth of raccoon dogs, around September most raccoon dogs have entered the body mature stage, at this time should be diligent to observe the eating status and fecal status. If there is always a small amount of food residue left at the bottom of each plate and the feces are slightly dilute, then
