Corn The amount of matter, the amount of energy in corn, the amount of protein in soybean meal

The energy content in corn is 78%. The nutritional content of corn is relatively comprehensive, generally containing protein, fat, sugar, calcium, and phosphorus. 21%, iron, also contains carotene, vitamin B1, hand Jingqi B2 and nicotinic acid as well as glutosterol, lecithin, vitamin E, lysine, etc.

The protein content of soybean meal is as high as 30-50%, which is one of the main protein feeds for animals.

Soybean meal is a by-product of soybean oil extraction. Also known as "soybean meal". According to different extraction methods, it can be divided into one soaked soybean meal and two soaked soybean meal.

Among them, the by-product of soybean oil extraction by extraction method is soybean meal, and the by-product obtained by extracting oil by pressing and then extracting oil is called soybean meal. In the whole processing process, the temperature control is extremely important, too high temperature will affect the protein content, which is directly related to the quality and use of soybean meal; Too low a temperature will increase the moisture content of soybean meal, and a high moisture content will affect the quality of soybean meal during storage. The production process of soybean meal is relatively advanced, with high protein content, and it is the main variety circulating in the spot market in China.

Each kilogram of corn contains 860 kcal, grams of carbohydrates, grams of fat, grams of protein, and 27 grams of fiber.

Corn is an annual monoecious cross-pollinating plant with tall plants and strong stems, which is an important food crop and forage crop, and is also the highest total crop in the world, second only to rice and wheat in terms of planting area and total yield. Corn has always been known as a longevity food, rich in egg white matter, fat, vitamins, trace elements, cellulose and so on.

It is the digestive energy of pigs, and the digestive energy value of different species is different, so this question depends on what the subject is aiming for? Person? Or an animal? Animals are divided into monogastric animals and ruminants, all of which are different.

The metabolic energy of corn is about 2% crude fiber, and the crude fat content is in. According to research, every 100 grams of corn contains 106 kilocalories, fiber, protein, fat, carbohydrates, and linoleic acid content reaches 2%, rich in mineral elements and vitamins.

Calcium: 10 mg.

Magnesium: 95 mg.

Zinc: mg. Copper: mg.

Two. Dried yellow corn grains: trace element content (mg 100 g) Calcium: 14 mg.

Magnesium: 96 mg.

Zinc: mg. Copper: mg.

Three. White cornmeal: trace element content (mg 100 g) Calcium: 12 mg.

Magnesium: 111 mg.

Zinc: mg. Copper: mg.

Four. Trace element content of yellow cornmeal (mg 100 g) Calcium: 22 mg.

Magnesium: 84 mg.

Zinc: mg. Copper: mg.

Different varieties of corn, the density of the grain is also different, to accurate numbers, I recommend you a method: drainage method, use a measuring cylinder to fill some water (to ensure that the water can not exceed the amount of corn you want to measure), and then put the weighing corn kernels into the measuring cylinder, see how much the water surface rises, the number of water surface rises is the volume of corn, density = weight volume.

Teacher of the Chinese Education Alliance: The bulk density of corn kernels is usually 750-780, and high-quality colloidal corn can reach 7900-800, so corn is graded, mainly according to bulk density, first-class corn, second-class corn, third-class corn, etc.

1.High available energy. The metabolic energy of corn is the highest among cereal feeds.

This is mainly due to the very low crude fiber in corn, only 2%; The nitrogen-free extract is as high as 72%, and the digestibility can reach 90%; Corn, on the other hand, has a high crude fat content, between to. Corn is an annual gramineous plant, also known as bud grain, cob, six grains, etc. According to research, every 100 grams of corn contains 106 kilocalories, grams of fiber, protein, fat, carbohydrates, mineral elements and vitamins.

Corn contains more crude fiber, which is 4-10 times higher than that of polished rice and refined flour. Corn also contains a lot of magnesium, which can strengthen the peristalsis of the intestinal wall and promote the excretion of waste products from the body. The above ingredients and functions of corn are very beneficial to the first place.

The flower ears of corn silk when the corn is ripe have a diuretic effect and are also beneficial to the **. Corn can be boiled into soup instead of tea, and can also be crushed and made into corn flour, corn cakes, etc. The puffed corn flower is very large, which can eliminate the hunger of obese people after eating, but the calorie content is very low after eating, and it is also one of the best substitutes.

2.High linoleic acid content. The linoleic acid content of corn reaches 2%, which is the highest content in cereal feed. If the proportion of corn in the diet reaches more than 50%, corn alone can meet the linoleic acid requirement of pigs and chickens (1%).

3.Protein.

The content is low and the quality is not good. The protein content of corn is about the same, and the amino acids are unbalanced, and the content of lysine, tryptophan and methionine is insufficient.

4.Minerals.

About 80% of the minerals are present in the embryonic region, and the calcium content is very small, about; Phosphorus is contained, but about 63% of it is in the form of phytate phosphorus, and the utilization rate of monogastric animals is very low. The content of other mineral elements is also lower.

5.Vitamin.

Among the fat-soluble vitamins, there is more vitamin E, about 20mg kg, and yellow corn contains more carotene, and there are almost no vitamins D and K. Water-soluble vitamins contain more thiamine, less riboflavin and niacin, and niacin exists in a conjugated form.

6.Lutein.

The average lutein contained in yellow corn is 22mg kg, which is one of the characteristics of yellow corn, and it is of great significance for the coloring of egg yolk, shins, claws and other parts.

Generally, it contains protein, fat, sugar, calcium, and phosphorus. 21%, iron, also contains carotene, vitamins B1, B2 and nicotinic acid as well as sitosterol, lecithin, vitamin E, lysine, etc.

Studies have shown that the nutritional value of specialty corn is higher than that of regular corn. For example, the protein, vegetable oil and vitamin content of sweet corn is 1-2 times higher than that of ordinary corn; The content of selenium, the "element of life", is 8-10 times higher; Of the 17 amino acids it contains, 13 are higher than those of ordinary corn. In addition, the moisture, active substances, vitamins and other nutrients of fresh corn are also much higher than that of old and mature corn, because the nutrient content of corn will decline rapidly during storage.

The nutritional content of corn is relatively comprehensive, generally containing protein, fat, sugar, calcium, and phosphorus. 21%, iron, also contains carotene, vitamins B1, B2 and nicotinic acid as well as sitosterol, lecithin, vitamin E, lysine, etc.
