Several commonly used feed a Muskrat, muskrat green fodder legumes with green feed, including grass, grasses, leafy and root feed, such as alfalfa, clover, ryegrass, sonchifolia, sweet potato vine, comfrey, S. Perfoliatum and weeds, leaves, etc. Second, roughage roughage including hay (grass family, legumes and other subjects hay) and straw (straw, soybean straw, corn stalks and other pod crustaceans) two. Which is characterized by low water content, high crude fiber content, less digestible substances, poor palatability, digestion rate, but the wide source, a large number of low price is one of the raw material feed Muskrat indispensable, usually in the diet proportional share of about 20%. Among them, because of the smell of hay aroma, palatability, and should be used as the main roughage musk rat; if feeding pod crustaceans, best after crushing and other fine material mixed into feed pellets. Third, concentrate feed concentrate feed includes energy feed and protein feed. Energy feed including corn, barley, wheat, rice and wheat bran. It features a rich starch content, palatability, digestion rate, less crude fiber content, protein content is not high, the phosphorus, sulfur more, less calcium, vitamin content is not comprehensive. Protein diet including vegetable protein feed and animal protein feed. Vegetable protein feed (such as soybeans, soybean meal, soybean meal, rapeseed and cottonseed meal, etc.) are characterized by protein-rich amino acid balance, nutrition is more comprehensive, there are a lot of fat, vitamin E and B, fragrance, palatability, general the proportion of the diet of 20-40% (rapeseed cake containing mustard seed factors, bitter and spicy mix ratio should generally be controlled at about 5%); animal protein feed (such as fish meal, pupa and flesh powder) is characterized by high protein content, there are more essential amino acids, especially lysine, methionine and tryptophan content rich, have more vitamins and inorganic salts, is commonly used to add protein feed. Fishmeal used to adjust and add some essential amino acids, but the price is higher, and there is a special fishy, ??poor palatability, mix proportions in the general control of about 9%. In addition, feed yeast is rich in protein, vitamins, fats and inorganic salts, its nutritional value is close to meal, the amount of the musk rat diets of 2-5%. Fourth, the inorganic salts feed feed mainly refers to salt, bone meal and powder, etc., the amount of the musk rat diets small, but significant role, is an essential component of musk rat diet. Table salt is sodium, an important source of chlorine, with musk rat enhance appetite and promote digestion and absorption of nutrients and maintain fluid balance and other effects, the amount of air-dried diet usually accounts for 1%. Salt can be dissolved in water mixed with concentrated feed or drinking for muskrats. Family musk rat bone meal can be made with the upcoming bones after eating livestock pressure cooking 1-1.5 hours to soften the bones, you can feed the musk rat after crushing dried. Feeding Amount can be accounted for 2-3% of the diet. Musk rat diet powder is the most affordable calcium feed. Shell powder is a cheap calcium supplement, calcium hydrogen phosphate calcium, phosphorus supplement. Five, feed additives feed additives can be divided into nutrition and non-nutrition categories. Common Muskrat amino acids with nutritional additives (mainly methionine, cystine and lysine), vitamins (vitamin A, vitamin D powder, vitamin E powder and multi-dimensional factors) and mineral supplements (salt, stone, shell powder and composite trace elements). Common Muskrat non-nutritional additives have growth-promoting agents and insecticide-care additives (such as Flavomycin, chlorobenzene guanidine hydrochloride, etc.), a flavoring agent (cream flavor, saccharin), plain flavor, preservatives (calcium propionate sodium propionate, etc.) and herbal additives (such as Gallus gallus, hawthorn, The Divine Comedy, Atractylodes, orange peel, Artemisia annua, leaves and malt, etc.) and enzyme preparations. Dai Nam musk rat breeding farming cooperatives have the qualification certificate, are special support industry model units, has been working on musk rat breeding techniques, varieties cultivation, promotion of large-scale breeding, farmers win-win cooperation. Dai Nam musk rat farming cooperatives have comprehensive standardized farming methods, technology applications covering musk rat nest build homes, feed formulation, disease prevention, foster pups, breeding and reproduction, musk extract a series of farming practices, has "kind of rat birth rate, the youngest son of a high survival rate; low incidence of the disease, the cost of occupancy is low, "the" two high and two low "technical advantages. Cooperatives adhering to the "letter to the Road to excellent for the win" business philosophy, always adhere to the "left farmers, factory hand," the whole industry chain cooperation.
