Fox fodder processing technology
Fur animal mink, fox's fangs are developed, the digestive tract is short, the stomach volume is small, there is no cecum, the food passes through the digestive tract faster, and the digestive gland secretes less amylase, more lipase, so its feed should be animal feed. In particular, animal protein feeds should account for a large proportion of the diet. Therefore, the feed processing and brewing methods for crickets and foxes have obvious characteristics. They are introduced as follows: 1. Feed types and utilization (a) Animal feed Various sea scads and freshwater fish are the main source of animal proteins of fleas and foxes. First, fresh sea miscellaneous fish contain more fat-soluble vitamins and can be fed whole. Some freshwater fish contain thiamine enzyme in the internal organs and viscera, can destroy thiamine in feed, cause VBI deficiency, appear loss of appetite, cause digestive dysfunction, and eventually die of gastroenteritis or gastric ulcer and other diseases, therefore, Freshwater fish should be fully cooked. However, puffer fish, horse dolphins, etc. contain toxins, easy to cause poisoning can not be eaten. Long-term single-feeding of mandarin fish (or an excessively large proportion) can cause lice, fox-deficiency anemia, and cotton wool as villus. Attention should be paid to iron supplementation, or to 10%-13% of livestock products or 20-25 grams of waste. / Only blood meal, Livestock and poultry meat is a full-price protein feed with high nutritional value. Fresh meat should be fed raw, but contaminated and stale meat should be cooked. Use of pox pork should be treated with high temperature and high pressure, and be properly matched with fish meal, rabbit head, rabbit skeleton, and pay attention to supplement of VE and yeast. It is best to remove the fat so as not to affect the lice, fox appetite and fertility. Rabbits and birds are susceptible to Pasteurella. Dogs are susceptible to canine dysentery and should be heated and cooked. Treated meat with estrogen cannot be used, otherwise it may cause deafness and follicle endocrine dysfunction, affect pregnancy rate, birth rate, or even infertility. Diseased meat and meat of unknown origin as well as suspected meats must be veterinary tested or treated with high-temperature harmless treatment. Fresh fish heads, fish skeletons, viscera, etc. can be fed raw, and it is better to mix with good quality sea miscellaneous fish or meat. The Liver of Livestock and Poultry has a laxative effect and the amount fed should not exceed 50 grams. The blood should be treated with high temperature and added in appropriate amount in October-November (accounting for 10%-15% of animal feed in the diet), which can improve the quality of plush. The stomach and lungs should be cooked and the thyroid glands on both sides of the trachea should be removed before the lungs are processed. Rabbit heads, rabbit skeletons and rabbit ears are used during the breeding period and the breeding period, and poultry by-products should be cooked. Dried fish, fish meal, blood meal, feather meal, etc. are dry animal feed. Dried fish has low fat content and can be used with liver, fresh meat, dairy eggs, and yeast. Fishmeal is widely used in cockroach and fox feed. If fishmeal has high salt content, it must be soaked with fresh water for more than 4-6 hours before use, changing water 2-3 times during soaking. Blood meal can be used with miscellaneous fish or meat, fish by-products. Feather powder is rich in sulfur-containing amino acids. Feeding 2-3 g/day in the spring-autumn moulting season is beneficial to the growth and development of plush, as well as the reduction of sputum, fox self-biting, and eating hair. Fresh milk should be used after heating at 70-80°C for 15 minutes. Use whole milk powder, should first stir in a small amount of warm water, and then diluted 7-8 times with boiling water, fed within 2 hours after preparation. In order to avoid spoilage. The feeding of eggs and foxes during the breeding period for eggs improves the quality of the semen of the common beast, promotes the development of mother embryos and the secretion of milk, and improves the survival rate of the beasts. Eggs must be cooked, otherwise the egg white contained in the raw eggs will destroy the biotin in the feed, causing dermatitis and follicles to have dermatitis, plush shedding and other diseases. "Mao eggs" must also be cooked. Pregnant females should avoid feeding 2-3 eggs, to prevent miscarriage and stillbirth. (b) Plant-based feedstuffs and grain feeds are the main source of carbohydrates in quail and fox diets and generally account for 10% to 15% of the total diets. Due to the low levels of enzyme secretion from pupa and fox, the digestibility of cereals is low. Therefore, feeding grain feeds after steaming can increase digestibility. Caterpillar feeds should also be fed after steaming, and the amount should not exceed 20% of the grain feed, otherwise it will cause indigestion and diarrhea. If cereals and cakes can be expanded and processed, the digestibility of animals can be greatly improved. Fruit and vegetable feeds generally account for 10% to 15% of the total diet. Spinach has a laxative effect and is usually mixed with Chinese cabbage. Unripe spoiled fruits or wild vegetables such as dandelion, bitter herbs, leeks, and mugwort can also be used instead of vegetables. Vegetables are strictly forbidden to accumulate in large amounts. When the temperature reaches 20-40°C, long-term accumulation will produce carcinogenic nitrite. Dishes that have been sprayed with pesticides must be removed before they can be fed. (C) feed additives vitamin A, Bl, C, E, etc. should be added, other vitamins are basically not missing. VA is derived from cod liver oil, marine animals and viscera of domestic animals; VD is mainly derived from cod liver oil, eggs and milk; VE is mainly found in green fodder, with rich wheat sprouts and lettuce; VB1: mainly from yeast; VC comes from fresh vegetables Female animals lack VC in their gestational diets, which can lead to newborn claws suffering from red claw disease. When fish is the main animal feed, phosphorus is often higher than calcium, and stone powder or shell powder may be added to the diet. For boneless meat or visceral diets, bone meal or calcium hydrogen phosphate should be added. Antibiotic additives have a certain role in preventing animal diseases and promoting the growth and development of juvenile animals and should be added in an appropriate amount. Second, feed processing modulation (a) the choice of meat feed to remove large chunks of fat, livestock and poultry should be removed gallbladder, thyroid gland, dry animal powder and grain flour to which the lump, impurities or foreign objects picked out , vegetables to go to the root and remove yellow leaves, rotten leaves. All feeds that have spoiled or come from infected areas must not be used. (2) Wash meat, fish, by-products of livestock and poultry, and feedstuffs for fruits and vegetables. Wash off dirt and silt with clean water before use. Mild loss or suspicious animal feed must first be disinfected with 0.05%-0.1% potassium permanganate for 5-10 minutes and then washed with water. (3) Soak fishmeal and bone meal with water for 4-6 hours (change water 2-3 times), soak dried fish for 12 hours (change water 2-3 times), and alkali dry fish for 1-2 days (every day Water 2-3 times), cocoon powder, blood meal and liver dregs powder as well as poor quality dried fish, dried stomach, etc., in addition to fully immersed, but also to cook. (d) Meat, fish, and viscera of poor cooking quality should be steamed and cooked after being disinfected with potassium permanganate; freshwater fish should be steamed for 2 hours; high temperature and high pressure must be applied after removing freshwater fish; grain flour Add water to make steamed bread and fully steamed. Each kilogram of flour can be cooked to make 1.8-2 kg of steamed bread. It can also be fried into noodles and then boiled with water to make it thick and porridge-like. Fresh beef and goat's milk should be burned and disinfected. The milk powder is diluted with boiling water; poultry eggs are cooked; blood meal should be boiled before feeding, and then mixed into the feed; spinach and bok choy washed in boiling water after boiling to remove bitter and astringent taste. All heat-treated feed must be cooled before mixing. (e) Weighing the type and amount of feeds specified in accordance with the feed-combination list and weighing them separately. (f) minced meat that will require processing. Separately use a meat grinder to mince the spare, bulky feed, knife can be cut into small pieces and then twisted. Hard feeds such as rabbit heads and rabbit skeletons should be crushed with a pulverizer and then twisted again. (7) The feedstuffs processed after the previous process has been processed are all concentrated in the feed tanks, and then the milk, water (or soymilk) and other supplemented feeds shall be added as required. Drug yeast or feed yeast can be added directly. Baker's yeast or brewer's yeast needs to add a small amount of water, heated to 70-80°C, and kept for 10-15 minutes. It can also be steamed together with cereal flour and bone powder can be added directly according to the amount. Feeds cannot be fed with yeast, VB1, etc.; drugs and vitamins should be put in last, and should be mixed evenly. The dilute consistency of the feed preparation should be appropriate, and the feed for the nursing mother and the weanling cubs can be slightly diluted. The feed room is often kept clean and hygienic. The processing equipment is often washed and regularly sterilized to prevent bacterial infection and spread the disease.
