What are the commonly used energy feeds for poultry?

The organic matter in the feed contains energy, and the so-called energy feeds are those rich in carbohydrates and fats, with less than 18% crude fiber and less than 20% crude protein in dry matter. The digestibility of these diets is high, with a dry matter metabolizable energy of 7.11~14.6 mj per kg of feed. The crude protein content is low, only 7.8%~13%, especially the lack of lysine and methionine; It contains less calcium and more phosphorus. Therefore, this kind of feed must be used with other feed such as protein feed.


(1) Corn corn contains high energy, less fiber, good palatability, high digestibility, is the most used in poultry feed, known as the title of the king of feed. Medium corn contained metabolizable energy (ME) of 12.97~14.64 mj/kg, and yellow corn contained more carotene. Feeding yellow corn to poultry could provide A certain amount of vitamin A, promote the growth, egg laying and yolk coloring of poultry. The disadvantages of maize are low protein content, lack of lysine, methionine and tryptophan, and low calcium and phosphorus content. In the poultry diet, corn can account for 50% to 70%.

 

(2) The energy of sorghum sorghum is similar to that of corn, but it contains more tannin (group acid), which makes the taste astringent and poor palatability. Excessive feeding can also cause constipation. In general, the amount in the diet is not more than 10% to 15%.

 

(3) Millet commonly known as millet, called millet after husking. The energy content of millet is similar to that of corn, the crude protein content of millet is higher than that of corn, which is about 10%, and the riboflavin (vitamin B) content is high (1.8 mg/kg), and palatability is good.

 

(4) Broken rice is processed rice sieve under the broken grain. The content of energy, crude protein, methylene, lysine and so on is similar to that of corn, and the palatability is good, so it is a good energy feed for poultry. Generally, the amount of energy feed in the diet can account for 30% to 50% or more.

 

(5)Wheat is similar to corn in energy, high in crude protein, more amino acids and B vitamins than other grains and seeds, which is a good energy feed for poultry. However, high quality wheat is expensive, so we can only use wheat (Mapy) which is not suitable for food ration as feed. Wheat is not mature wheat, grain is not full, its protein content is higher than wheat, palatability is good, and the price is relatively cheap.

 

(6) Barley ,  Oat Barley and oat are lower in energy than wheat, but rich in B vitamins. Because its shell is rough and hard, not easy to digest, need to be broken or germinated after a small amount of collocation feeding.

 

(7) Wheat bran crude protein content is high, up to 13%~17%, B vitamin content is rich, soft texture, good palatability, is a common feed for poultry. Because of the high content of crude fiber, large volume and laxative effect of wheat bran, the dosage should not be too much. In general, the amount of vitamin birds and adult birds can account for 5%~15%, and the amount of adult birds can account for 10%~20%.

 

(8) Rice bran is a by-product of rice processing. Its composition varies significantly with the whitness of processed rice. Rice sugar contains low energy, high crude protein content, rich in B vitamins, more phosphorus, magnesium and manganese, less calcium, high crude fiber content. Because rice bran contains more grease, it is easy to deteriorate after long storage. In general, the amount of rice bran in the diet can account for 5% to 10%.

 

(9) The crude protein content of sorghum bran is slightly higher than that of corn, and it is rich in B vitamins, but it is high in crude fiber, low in energy, and contains more tannin (the combination of tannin and protein precipitates, which affects the digestion of protein and has poor palatability). Generally, the amount in the diet should not exceed 5%.
