How to make broiler feed formula? This question is not the same as "how to make chicken feed pellets for broilers". The first question is about the formula of broiler chicken feed, while the latter question is about the method of processing chicken feed in 10-20 ton per hour broiler chicken feed factory.
Broiler feed and chicken feed shall contain energy feed, protein feed, and mineral feed, vitamins, and additives. Richi Machinery is a professional china poultry feed production line factory. This article will tell you how to design a perfect chicken broiler feed formula, and how to allocate the proportion of each ingredient according to nutritional requirements.
According to the characteristics of the feed, the common feed for broilers can divide into energy feed, protein feed, vitamin feed, mineral feed, and special additives feed. Feed pellet machine is dispensable equipment to make animal feed pellets.
①Corn: It is one of the most important energy feeds for broilers. Rich in starch and crude fat. When formulating the diet, the amount of corn generally accounts for 40% to 70% of the diet.
②Broken rice: It is the broken grain rice screened in rice processing. The starch content is high, the crude fiber content is low, and it is easy to digest. Its nutritional value is similar to that of corn, and the dosage is about 30% to 50% of the diet.
③Wheat: High nutritional value, energy content close to corn, more protein content, amino acid than other cereals, vitamin B is also very rich, palatability is good, the amount of easier to stick chicken mouth and affect feeding. It can generally account for 10% to 25% of the diet.
④Barley: It contains 15% to 20% of the skin, the energy is about 75% of the corn, the crude fiber content is 3 times higher than the corn can account for 10% to 15% of the diet.
⑤Rice bran: It is a by-product of rice processing, mainly composed of skin and rice embryo. Its crude fat, crude protein, and crude fiber content are higher than rice, rich in vitamin B, often used as auxiliary materials, the amount should not be too much, generally accounting for 8% to 10% of the diet.
⑥Wheat bran: It is a by-product of wheat processing. It contains crude protein, vitamin B, and manganese, etc., has a laxative effect, the dosage should not be too large, the general broiler dosage does not exceed 8%.
Protein feed can divide into plant protein feed and animal protein feed. Plant protein feeds such as bean cake, peanut cake, cottonseed cake, rapeseed cake, and so on. Animal protein feed such as fish meal, blood meal, meat and bone meal, feather meal, silkworm cocoon, and other processing by-products.
① Bean cake: A by-product of soybean oil processing from soybean oil. Bean cake contains more than 40% protein, ranking first in plant protein feed, and is rich in lysine, with high nutritional value, generally accounting for 15% to 20% of the diet.
②Cottonseed cake: its protein content is second only to the bean cake, up to 30% to 35%, but it should not be used simply as a dietary plant protein feed, because of the lack of lysine. The amount can not exceed 10% of the diet, because the cottonseed cake contains gossypol, too much feeding can cause poisoning.
③Rapeseed cake: 25% to 30% crude protein, low lysine content, higher methionine content than bean cake, but the rapeseed cake contains mustard enzyme. Which can promote the decomposition of sinapinic acid into toxic substances, so the amount of feed should not be too much, generally less than 5%.
④Fish meal: It has high nutritional value and comprehensive amino acid content. The crude protein content of high-quality fishmeal is higher than 60%, the salt content is less than 2%, and the water content is below 12%. Fish meal can generally be used in an amount of 5% to 12% of the diet.
⑤Blood powder: It is a brown powder feed made by cooking, pressing and drying the blood of animals. The crude protein content is as high as 70%-80%, rich in lysine, but lacks methionine, cystine and isoleucine, and has low solubility. It is not easy to digest, and has poor palatability. It should be mixed with other protein feeds. Not more than 3% of the diet is appropriate.
Due to the high moisture content of fresh green and green feed, the dosage should not be too large, so as to avoid causing squatting and affecting fattening of broilers. Green leaves, grass leaves, etc. are dried and pulverized to become high-quality grass powder or leaf powder, such as alfalfa powder, eucalyptus leaf powder, etc. are good vitamin supplement feeds, generally accounting for 2% to 5% of the diet.
When the mineral content in natural feed is insufficient, or when some elements are unbalanced, attention should be paid to replenishing the mineral feed in the diet, especially for high-yield broiler breeders and broilers with fast-growing growth. Should pay attention to supplement. The commonly used mineral feeds are mainly the following:
①Stone powder: Calcium content is 35% to 38%. The dosage generally accounts for 1% to 3% of the diet, and the broiler breeder can reach 5%.
②Shell powder: Containing about 38% of calcium, often used as feed for calcium supplementation. It usually accounts for 1% to 3% of the diet, and up to 5% of the broiler breeders during the laying period.
③Salt: In the preparation of the diet according to the actual salt content in the feed, and then consider the amount of salt added to avoid excessive or insufficient salt. The general dosage does not exceed 0.38% of the diet.
In order to promote the normal growth of broilers, prevent the disease, increase the yield and economic benefits. In modern broiler breeding, the use of additives such as amino acids, vitamins, trace elements, antibiotics, antioxidants, antifungal agents. The types and dosages to add should determine according to actual needs. For example, in most feed diets, vitamins and trace elements are incomplete. It should note that appropriate proportions of multivitamins and trace element additives should add, generally accounting for 0.05% to 0% of the diet. It is often rainy and humid in summer, often with anti-fungal agents and antioxidants. Add the additive to the feed and mix well and mix well. Before the broiler is marketed, the feed should not contain any drugs.

To ensure GMP cleaning is an important aspect. Different type of cleaner used for this purpose.
All transportations like bucket elevator, screw & chain conveyor etc. for conveying finished goods.
Raw materials need to be grinded as 225 m/microne perticle size by chicken feed crusher for different type of feed.
Different R/M are mixed here with additives, oil/fat, medicines, etc. Good chicken feed mixer ensure good quality.
Produce final chicken pellet feed. A good pellet means "A complete feed" and a good chicken broiler feed pelletizer machine can ensure that.
Extruded feeds are about 70-90° C. Chicken feed cooling machine bring down it at normal temperature (+4° max).
