Method for grazing of commodity broiler chickens

The broiler raising method has a great influence on the quality of the meat. It is more important to use the proper feeding method to obtain good chicken quality for the broiler chickens that produce high quality poultry meat. In the modern production of broiler chickens, feeding methods combining intensive brooding intensive breeding with grazing during the finishing period are commonly used. There are mainly the following ways of free-range chickens.

1 yard backyard

In the courtyard of the farmer's courtyard, a nylon net or fence is used to surround a piece of open space and the chickens are housed in the yard. The feed was mainly fed with compound feed, supplemented with green feed. This type of feeding is relatively small, usually 200-500, but the management is convenient, the production speed is faster, it is worth promoting. The courtyard free-range chickens are basically the same as the above methods in management. The management should pay attention to the adaptation process from stocking to outside the house and maintain a stable temperature transition. The grazing temperature at 32 days is about 26°C, and the adaptability to outside air temperature increases as the chicken age increases. Pay attention to the local weather forecast. If there are big changes in the weather in the future, effective measures should be taken early to mitigate the adverse effects of sudden temperature changes on the flock. The free-range chickens in the courtyard are also active for a long time. Therefore, keep the inside of the house dry. Lay clean, dry, mildew-free shavings, sawdust, rice bran, wheat straw, etc. in the house to make chickens in the house. Living on litter, you can also use the method of online feeding to keep the chicken off the ground and leave the feces. Maintaining a suitable breeding density is beneficial to the growth, health, and evenness of the flock. Generally, the stocking density is 1-2 weeks old, 35-45 animals per m2, 20-30 animals per m2 at 3 weeks of age, 15-20 animals per m2 at 6-7 weeks of age, and 10 animals at 8 weeks of age. - 15/m2. Daytime natural light and artificial light photosynthesis combined, light 16h a day. To maintain the hygiene of the chicken's living environment, the chicken house should be cleaned regularly, and the dirty litter should be cleaned out and accumulated in a place farther away from the house for fermentation. The playground should be cleaned regularly. Garbage containing chicken manure, grass stems and feed must be kept in a fixed place. Inside and outside the house should be sterilized regularly. Control harmful microorganisms in the environment to a minimum level to ensure the safety of the flock. The chicken likes to lie down on the branches and sticks during the rest of the night. Placing a perch in the house allows chickens to inhabit it at night. The advantage is that it can reduce the relative breeding density and reduce the direct contact with the feces. The habitat uses a few semi-circular wooden sticks to nail the ladder like two wooden sticks.

The garden free-range chickens are mainly fed with feed. The feed is the main reason that affects the growth rate and meat quality of chickens. Farming chickens can also provide animal feed for chickens through artificial brooding. The green feed must be varied and placed on a shelf made of wooden sticks to allow the chicken to feed freely. The nutrients in various green feeds can complement each other. Feeding a single green feed for a long time has a negative impact on the growth and health of the chicken. Some green feed contains some anti-nutritional factors that affect the absorption of other nutrients or chronic poisoning.

2 Grazing grazing between forests

There are many forests around the village, on the bank of the river bank, etc. There are many weeds and insects in the woodland. Stocking the flock in the woodland can make full use of the wild feed resources and reduce feed costs. For trees that have been produced for many years. Feeding management requirements for stocking flocks are basically the same as that of orchard chickens, but unlike in orchards, woodlands are rarely sprayed with drugs to prevent pesticide poisoning in chickens. A large number of wild animals in forest lands may endanger the safety of local chickens and require more attention. In some places where chickens are stocked in nurseries, it is important to note that the spring stages of sprouting do not allow the flock to move into the nursery to avoid damaging the seedlings. When the height of the seedlings grows to about 1m, the chickens can be considered for stocking.

3Farmland grazing rearing

In the season of relatively high temperatures and low rainfall in April-June each year, a simple shed is constructed between the wasteland of the riverbank using plastic woven cloth or cement tiles, and the grazing chickens are stocked for free use. Eat green grass, insects, weed seeds and other wild feed.

In many parts of China, the 3-6 months of each year are the seasons with relatively little rainfall. There are large areas of tidal flats on both sides of some larger rivers, especially the Yellow River, which has the largest beach area. Some areas where there are no crops are grown with weeds and there are many insects, especially in the relatively dry season, which breeds a large number of locusts, causing serious damage to nearby crops. When locusts are harmed, a large number of pesticides need to be sprayed on airplanes along the Yellow River beach and its banks to control locust infestations. Although this method of extermination can control locust plagues in a short period of time, it takes a lot of manpower and financial resources. Pesticides kill the natural enemies of beneficial insects and aphids, pollute the soil and cause adverse effects on the ecological environment of the area. The use of the natural feeding resources of the mudflat to stockpile the chicken can not only produce a large amount of high-quality chicken meat, but also control the occurrence of locusts, save a lot of manpower and financial resources, and effectively protect the ecological environment.

3.1 Facilities

Grazing hens should be housed in a high-lying, dry, well-ventilated place in order to prevent flooding and mosquito and insect damage to chickens and managers. Prepare a three-wheel tractor and a back-up generator to supplement the light at night and extend the chicken's feeding time. Dig the well to feed the birds. Other feeding and management facilities are the same as those for grazing in orchards. When choosing a pastureland, consider the shading problem when the sun is hot in the summer and prevent chickens from suffering from heat shot disease when grazing.

3.2 Feeding management

The time of grazing in the Central Plains region should generally be selected from March to April. After April, the temperature is mild. The wild feed resources in the beach area are abundant and can provide sufficient food for the flock. The density of grazing in the mudflats can be adjusted to approximately 10 per 100m2 depending on the local climate and the richness of the hatched feed. The best way is to allow the birds to be grazing for 7 days on one beach and then transfer to another on the beach. Rotational animal husbandry. The use of solar cells or generators to generate electricity as a light source for illumination can prevent wild animals from invading the flock and attract all kinds of insects, allowing the birds to prey at night, as well as preventing accidental death and loss of chickens.

4 Barren hills and sloping grazing rearing

The area of ​​barren hills and slopes in China is very large and has been idle for a long period of time. This not only destroys the ecological balance, but also causes serious water and soil erosion, and wastes a large area of ​​land resources. The use of grazing in barren hills and wasteland is not only conducive to the country's policy of returning farmland to grassland and returning farmland to forests, but also conducive to the production of local chickens. The grazing method is basically the same as the above methods. The sheds should be built on leeward sunny slopes with relatively gentle slopes, which can prevent the north wind from attacking the flock and prevent flood damage. On pastures, quality legumes such as alfalfa should be planted, and apricot trees should be planted on the grass. Apricot trees can serve as a sun-visor, and the leaves of apricot trees are high quality feed.

5 grass hill grassland grazing

Grazing Grassland Grassland grazing and rearing is the use of grassland grassland grassland as the natural resources for grazing and rearing poultry, production of green poultry products and prevention of disaster relief. Grassland vegetation in grassland in the south covers a large area, vegetation is lush and insects are abundant, and it takes a long time to grazing for one year. Grassland grassland grassland in the northern part of the grassland turns green later, and the green grass period is shorter. The grazing time is mainly from June to September. The grazing season is short, and one year grazing once is one of the effective measures for preventing and treating flood disasters. Grazing on Grassland Grassland Grassland Grazing in the south should be planted on pasture. Trees can be shaded and shaded in summer to prevent chickens from developing heat sickness. The construction of simple poultry houses should be easy to move and move. Other feeding and management methods are the same as the above methods.

6 Corn field grazing rearing

The method of grazing in the corn field is basically the same as the above feeding method. A simple chicken house is built in the middle of the grazing area for chickens to feed and drink in the evenings and stormy days. The appropriate amount of feed is supplemented sooner or later, and the chicken is allowed to feed freely in the corn field for the rest of the time, and the stocking density is 0.15-0.23/m2. This feeding method can prey on weeds and pests in corn fields, saving both pesticides and labor.

7 Cotton grazing rearing

The grazing and feeding facilities in the cotton fields are the same as those in the above grazing and rearing. The stocking density is 0.15-0.23 birds/m2, and the cotton field is enclosed with a simple plastic net to prevent the chickens from running to the outside. The stocking season should be carried out when the cotton grows above 30cm. When cotton is grazing and feeding, it is necessary to prevent pesticide poisoning. Although the grazing cotton fields do not need to be sprayed with pesticides.
