Energy Feed: Common energy feeds include cereals, bran and fats. Corn: Rich in starch content, it is the highest energy content feed in cereals. Corn has good palatability, and yellow corn is rich in carotene and lutein, which can increase the yellowness of the skin. It can account for 50-78% in the yellow chicken feed formulation. Wheat: Energy is second only to corn. Its crude protein content is relatively high, and its amino acid content is also better than other cereals. It has good palatability and is easily digestible. However, its viscosity is large and the amount used is generally not more than 30%. Feeding with wheat-based grains, the chicken has poor yellow skin. In addition, wheat processing by-products such as sub-powder, bran, can also be used as feed, the amount of secondary powder should be controlled below 25%, and bran is generally not more than 15%. Brown rice: energy is similar to corn, protein content is about 7-9%, calcium content is small, phosphorus content is large, but the effective utilization rate of phosphorus is low, and the content in the diet is generally controlled at 20-40%. Grease: The commonly used animal fats are lard, butter and chicken fat; commonly used vegetable fats are soy oil, tea oil and palm oil. The amount of fat in the diet is generally between 1-5%. Protein feed: feed with crude protein content of more than 20% and crude fiber content of less than 18%, known as protein feed. Protein feed is divided into vegetable protein feed and animal protein feed. Vegetable protein feed: Mainly soybean cake, rapeseed cake, cottonseed cake and peanut cake. Soybean cake has higher protein and lysine content and is a good protein feed commonly used by chickens. Generally, the amount is below 35%. When animal protein is lacking or the price is too high, adding methionine to a corn gluten-based diet formula can easily balance various nutritional parameters of the diet formula, and the formula price is also more economical. The rapeseed cake contains mustard meal and the cottonseed cake contains gossypol. The dosage should be limited. The proportion in the diet should be less than 8%, and the latter should be less than 2.5%. Animal protein feed: fish meal, meat and bone meal, feather meal and blood meal. Fishmeal has a high protein content and amino acid composition, especially high levels of methionine and lysine, rich vitamin B family, calcium and phosphorus, and good absorption and utilization. It is an ideal animal protein feed for chickens. The quality of meat and bone meal is worse than that of fish meal, and the amount used is generally not more than 5%. Feather meal and blood meal protein content is higher, but amino acids are not balanced, and absorption and utilization are also inferior to fish meal. The dosage should not be too high. The content of fish meal in the diet generally does not exceed 8%. In addition, the protein content of yeast feed is as high as 45-60%, and the general addition amount is 2-5%. The protein content of corn gluten meal is as high as 40-65%, and contains more methionine and lutein, and the amount of dietary supplement is 2-8%. Mineral feed: Mainly refers to the feed that provides constant mineral elements such as calcium, phosphorus, sodium and chlorine, such as shell powder, stone powder, calcium hydrogen phosphate powder, bone powder, eggshell powder and salt. Shell powder contains high calcium and phosphorus content and is easily absorbed. Stone powder has high calcium content and is inexpensive. It is the main raw material for calcium supplementation. Dicalcium phosphate powder has high phosphorus content and is a raw material for phosphorus; salt is supplemental sodium and chlorine. The raw material, usually 0.3-0.4%, no fish meal diet can be higher, but to control. Excessive use of salt will cause the chicken to drastically increase drinking water and even poison. Vitamin feed: green feed is rich in carotene and vitamin B family, also contains certain trace elements, is the source of vitamins required by the chicken body, such as weeds, artificial cultivation of pasture, melon vines, vegetables, etc., for the production of high quality yellow Chicken has a certain value. Large-scale breeding of chickens, the main source of vitamins is dedicated vitamin additives. Additive feed: In order to balance and meet the nutritional needs of chickens and ensure the full price of the compound feed, you must add trace or small amounts of additives, such as amino acids, vitamins and trace elements, to the feed diet formula. Additives are divided into nutritional and non-nutritive categories. Nutrient additives include vitamins, trace elements, and amino acids; non-nutritive additives include antioxidants, mildew-proofing agents, anthelmintic drugs, health-care drugs, flavoring agents, and colorants. Fertilization method of traditional Chinese medicine: In summer use 23 grams of licorice, ginger powder, Wujiapi, 12 grams of dried chili, 7 grams of star anise and 12 grams of ferrous sulfate; 24 grams of ginger powder in winter, 50 grams of cinnamon, 9 grams of gallbladder, and star anise 8 grams and 9 grams of ferrous sulfate, in the fattening stage of yellow chicken, research into fine and mix in the diet, the average chicken fed 0.5-1 grams per day, fed once in two days, there is a significant effect of fattening. Add sodium sulfate: From the 10th day of age, add 0.3% sodium sulfate to the total weight of the feed. Long-term feeding has a long-lasting effect. Add chlorpromazine hydrochloride: This agent has a sedative and weight-gaining effect on yellow chickens. Each chicken is fed 3-5 mg daily. Even feeding 15 days can increase 15-20%. Adding fat chicken powder: Formula: 50% cinnamon, 20% dried ginger powder, 9% licorice powder, 7% fennel powder, 6% cooked soybean powder, 8% ferrous sulfate, 0.5-1 grams per chicken Feed the ingredients and feed them once in two days. After half a month, the average daily gain of each chicken can reach 25-50 grams. Adding multi-enzyme tablets: After the third day of the start of the chicks' feeding, add 0.04% multi-enzyme tablets to the diet (graining, mixing), and feed them for 2 weeks to increase the daily gain of chicks by 8-10%. The feed conversion rate increased by more than 4%. Add methionine: Add 4 grams of methionine and a small amount of multivitamins to every 5 kilograms of diet and feed for 6 weeks to make the yellow chicken weigh 1.5 kilograms. Adding soy bean oil: 1 week before slaughter of the yellow chicken, add a little soy oil to the diet, and add sublimed sulfur powder according to 2/10000 of the total amount of feed to make the yellow chicken tender. Adding fats and oils: In corn- and wheat-based diets, adding 2-8% of animal fat makes yellow chickens significantly heavier. Filled with cooked corn: 200 grams of cooked corn per bird per day, three meals a day and artificial feeding, appropriate feeding of vegetables, can make the yellow chicken immediately before slaughter weight gain. Adding sterile fly maggots: Using distiller's grains as a bait to produce sterile fly maggots, each feeding 500 grams of fresh quail, can make yellow chickens produce 0.9-1 kilograms of meat. Add feed 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 蚯蚓 å“ å“ Dry products contain 70% of crude protein, processed into powder or freshly fed, and can be mixed with 7.5% diet. Adding Ai powder: Adding 2% Ai powder to the chicken diet can increase the chicken's daily weight gain by 10-20% and feed consumption by 7-12%.
