What are the methods of processing chicken green feed?

Green chicken feed is fresh, juicy, and nutritious. It is the material basis for scientific and efficient breeding of chicken farms. The wise use of green food is not only beneficial to the health of chickens, but also can effectively improve the efficiency of feeding, but the breeding must be scientific.

Today I would like to share with you the effective methods of raising chickens with green food.

Crushing is the easiest and most comfortable way to make green food. After crushing, it promotes the swallowing and digestion of chickens, and is generally used to raise chickens, and the dry feed and leaves after drying and crushing can be used to prepare chicken feed, supplement green foods such as raw fiber and vitamins in the diet. The harvest period is as follows:

legumes from flowering to flowering, from heading to flowering; Leaves in autumn.

1 At 35 days of age, concentrate should still be the main food. After 4 days of age, the greens can be chopped and mixed into a concentrate of about 20% and no more than 35%. During the fattening period (36 to 80 days old), farmers who like mountain forests should pay attention to the fact that during the fattening period, mountain forests have a certain impact on the growth and development of chicks during the daily feeding and + green feed feeding, and the full price is fed in the morning and evening.

If you choose cage mode, therefore, the ratio of carnivorous feed to concentrated feed is about 1" (no. During feeding, you should first feed a complete** concentrated feed and place the same amount of green space in the feed straw after an hour so that the chickens can eat freely. In order to achieve the fattening effect, in view of the fact that the amount of feed in the green feed should be reduced to less than 10% 15 days before the market, and the total concentration should be supplemented;

Natural drying should suspend the harvested feed in situ for 5-7 hours, but if the moisture content drops to 30% to 40%, move it to a dark place for air drying. If the moisture content is 16% to 17%, it can be stacked or packaged for storage. During stacking, the opening must be kept in the middle of the stack.

In northern China, the moisture content of hay should be less than 17%, and in southern China, it should not exceed 14%. The natural drying of green leaf feed should be placed in a well-ventilated place, dried in a cool place, and should be rotated frequently to prevent heating and sun exposure, so as not to affect the quality of the product. After crushing, it is best to use nylon or plastic bags for sealed packaging and storage.

The shredding method is the simplest processing method for green feed, and it is often used by farmers to raise chickens in small quantities. After the green feed is chopped, it is good for the chicken to swallow and digest.

After the drying method of drying grass and leaves after crushing and processing, it can be used as raw materials for chicken feed to supplement the crude fiber, vitamins and other nutrients in the feed The harvest period of green feed is: grass forage heading to flowering stage, leguminous forage from early flowering to full flowering stage, and leaves in autumn.

Chopping method, drying method, natural drying, artificial drying, stirring method, these are all methods that can be used.

To crush the feed, dry the feed thoroughly, add some nutritious ingredients, stir thoroughly, and pay attention to the proportion of feed.

Green feed refers to green feed, leaves and non-starchy roots, tubers, melons and fruits with a natural moisture content greater than or equal to 60%. Green feed contains a lot of water, generally up to 75% to 95%. As a result, fresh grass has a lower dry matter content.

However, according to the calculation of dry matter, its protein content is rich, generally gramineous forage contains 13% 15% crude protein, leguminous forage crude protein content is as high as more than 18%, and its quality and nutritional value are high. Green feed is rich in vitamins, especially carotene content up to 30 80 mg kg, higher than other feed; Green feed is also rich in B vitamins and more vitamin E, but it lacks vitamin D. The calcium and phosphorus content in the green feed is abundant, the proportion is appropriate, the calcium and phosphorus in the green feed are mainly concentrated in the leaves, and the carbohydrates contained in the green feed contain more nitrogen-free extract and less crude fiber, so it is easy to be digested and absorbed by livestock.

The processing and modulation methods of green feed are as follows: (1) After mowing the green fodder, it is shredded into 1 2 cm long and then fed to livestock and poultry, which can achieve the effect of "three knives per inch of grass, and no material is fat".

2) Sun-dried green fodder is tender and juicy, palatability is good, and rich in nutrition. However, as the plant matures, the stems and leaves become thicker and harder, and the utilization value also decreases. Therefore, in order to ensure the good quality of green fodder, it must be harvested at the right time.

Leguminous green fodder for pigs and chickens should be harvested before pregnancy buds; Those who are fed to cattle, sheep, and horses are harvested at the peak of flowering. Because it is perishable to be stacked after harvesting, it should be dried in time to make green hay for winter use, but it should not be exposed, otherwise it will destroy the nutrients in it.

3) Pulping to remove foreign bodies from green fodder, wash, cut short and then pulp, can eliminate the burrs on the surface of some feed stems and leaves, which is conducive to livestock and poultry feeding, and improves the utilization value of feed. However, the amount of water should be controlled to avoid excessive water content and insufficient nutrient intake by the animal.

4) Softening the green fodder with bitterness, spicy or other peculiar smell soaked in cold water or soaked in hot water for 43 minutes, and then mixed with other green fodder to feed livestock and poultry, not only can remove the peculiar smell, but also soften the cellulose, improve palatability, and increase the utilization value. But be careful not to soak for too long.

The first method is to chop all these feeds, wash them, and then feed, the second method is to be exposed to the sun for a period of time, the third method is to boil with hot water, the fourth method is to choose machine processing, the fifth method can be cooked in a pot, and then to feed it is conducive to swallowing, but also to promote digestion, which is good for the body.

The first method is to use professional props to chop them up and then feed them, the second method is that they should be placed in the sun for a period of time, air dry, and then use for them, the third method is to soften them first, soak them and then add some feed, feeding, are relatively easy to absorb.

The feed needs to be chopped, and the feed needs to be dried, and at the same time, it is necessary to pay attention to the matching, and it is also processed by equipment, and it also needs to be processed manually.

1.Select chopped, 2Carry out drying, 3Processed feed, 4Carry out package collection, 5Methods such as compression can be used.

The processing method of chicken green feed is to chop the feed, then air dry, add vitamins, and then store and ferment, and it will be good after a week.

<> commonly used green fodder for raising chickens are: sweet potato vine, pumpkin, carrot juliang sale, cabbage, cabbage, digging wild vegetables, etc. Green feed nutrition is comprehensive, palatability is good, poor key, easy to digest, low cost, rich in vitamin content, due to the high moisture content of fresh green feed, the dosage should not be too large, so as not to cause diarrhea and affect the fattening of broilers.

There are many things that can be added to chicken feed. There are many things that can be added to the finished chicken feed, but the premise is that these things are crushed better, such as adding crushed corn, wheat bran, soybeans, tofu residue, green vegetables, etc.

1. Add garlic, usually garlic powder, the addition amount is 2% of the diet, which can make the chicken flavor stronger and have no adverse effect on the growth of chicken. 2. Add silage, add 15% silage in the daily compound feed worker, and add 5% grass or plant straw, which can make the meat flavor of captive chickens the same as the meat flavor of natural free-range chickens, and can enhance the disease resistance of captive chickens. 3. The chickens stocked by farmers with humus soil are very rich in nutrients due to pecking grasses, rotting leaves, insects and sand, etc., which greatly improves the meat quality and flavor of chickens.

In the chicken farm, the humus on the surface of the vegetable garden or orchard soil can be dug out, dried at room temperature, and fed to chickens after being mixed with the proportion of compound feed accounting for 70%-85%, green fodder accounting for 10%-20%, and humus soil accounting for 5%-10%; Or mix according to the proportion of chicken compound feed accounting for 75%, forage feed accounting for 15%, and humus soil accounting for 10%, and feed chickens as a ration after full mixing. The meat quality and taste of the chickens fed in this way are similar to those of farmyard chickens; The eggs laid by laying hens are also the same as those laid by farm chickens, with bright yellow egg yolk and thick egg white.

The chick feed formula is corn + soybean cake (meal) + mineral premix (including health care drugs). If you want to reduce the cost of feed, you can use bran and secondary flour to replace corn or replace soybean cake (meal) feed with cottonseed meal and rapeseed meal, but the minimum energy concentration and crude protein content should be maintained.

What are the feed ingredients used to prepare the full price diet for chickens?

1) Energy feed. This type of feed is rich in starch, sugar and fiber, including cereals, bran, roots, tubers and melons, as well as oil, sugar residue, etc., which is the main component of chicken feed, accounting for about 60% of the full price diet. The energy feeds commonly used in the diet are corn, wheat, barley, bran and broken rice, grass seeds, sorghum, etc.

The crude protein content of this kind of feed is generally not more than 15, and the crude fiber is less than 18, so feeding chickens with this feed alone can not meet the needs of chickens, and it is easy to fatten chickens.

2) Protein feed. Protein feed refers to the feed with a crude protein content of more than 20 and a crude fiber content of less than 18 in the dry matter of the feed, and the use of feed with high energy value. According to different categories, it can be divided into two categories: plant-based protein feed and animal-based protein feed.

Plant-based protein feeds include cake meal, leguminous seeds and some processing by-products. This type of feed is characterized by rich protein content, high content of essential amino acids, but insufficient calcium, sodium, iron, rich in copper and zinc, manganese is also quite large, high content of phosphorus, but low utilization rate. In addition to vitamin E, other fat-soluble vitamins are missing.

Lack of B12 in water-soluble vitamins. The most commonly used are soybean cake, soybean meal, peanut cake meal, rapeseed cake meal, cotton nut cake, corn gluten powder, mung bean protein powder and other protein feeds. Animal protein feed includes fish meal, meat and bone meal, silkworm chrysalis meal, earthworm meal, shrimp bran, blood meal, feather meal and feed yeast.

This type of feed is characterized by a high content of protein and essential amino acids, a high content of minerals, a high content of calcium and phosphorus, and a rich content of B vitamins, especially BI, and shame.

3) Mineral feed. Mineral feed is more specific feed containing nutrients, plant feed is generally lacking in sodium, chloride and calcium, the general natural feed of the diet, minerals in the quantity and proportion can not meet the needs of chickens, need to add a variety of mineral feed. Mineral feeds commonly used to supplement calcium are:

Calcium carbonate powder, shell powder, eggshell powder, etc. Mineral feeds supplemented with phosphorus include bone meal, calcium phosphate, dicalcium phosphate, etc.

4) Vitamin feed. It can be divided into two categories, one is commercial vitamin additives, including single vitamins and multivitamins, such as VA, VD, H, VX, complex vitamin B, choline, vitamin premix, etc. The other category is a variety of green fodder and processed products, such as silage, green hay meal, leaf meal, etc.

5) Additives. The so-called additives are substances added in small or micro amounts in livestock and poultry diets in order to fully meet the nutritional needs of livestock and poultry, or to promote the growth of livestock and poultry, prevent diseases, or to facilitate feed preservation and improve the quality of livestock products. Including nutrient additives, i.e., amino acids, vitamins and trace element additives; growth promoters; anthelmintic health care additives, such as sulfonamides, furans, arsenic preparations and anti-parasitic drugs; antioxidants such as ethoxyquinoline, etc.; Antifungal agents such as sodium propionate.
