Here are some tips for raising chickens in orchards:
1 ? Woodland selection?
Generally speaking, it is better to raise chickens in medium-sized forests and woodlands with forest (fruit) age of 3 ~ 5 years, and it is most ideal to raise chickens in medium-sized forests with sparse canopy, high canopy, 60% ~ 70% shade and abundant weeds and insects in woodlands. Forest land with dense branches and leaves and large shade has poor light transmittance, which is not conducive to the growth of chickens.
Peach, pear and other fruit forests with few fruits are suitable for planting grass and raising chickens. Mulberry orchards, citrus orchards and loquat forests are also good places to raise chickens. Some fruit trees, such as peaches and pears, will rot after bearing fruit, and chickens are easy to be poisoned after eating rotten fruits, so it is not suitable for raising chickens in this woodland.
2 ? Variety selection
Raising chickens under the forest has the characteristics of "stocking and supplementary feeding". Chickens under the forest should choose breeds that have passed the examination and approval of national and local breeds, as well as breeds that are interbred among local chickens and have a blood relationship of more than 75%. These breeds of chickens have strong adaptability, strong disease resistance, strong foraging ability and rough feeding resistance. They are medium and large in size, bright in color, tall and slender in gaskin, blushing with big crowns, good in quality and good in flavor.
3 ? Feed selection
Chickens under the forest can be fed with feeds and additives that meet the standards of green food. During stocking, plant protein feed can be supplemented. Chickens should use less or no animal feed such as fish meal during fattening, and it is forbidden to use toxic and harmful additives and residual veterinary drugs. In addition, forage grass, leaves, seeds, insects and microbial preparations can be reasonably used to ferment feed and agricultural and sideline products to feed chickens.
When raising chickens under the forest, we can feed on insects, grass and minerals rich in woodland to meet the body's demand for these nutrients, while energy, protein and trace elements need to be obtained through supplementary feeding.
Free-range chickens like to eat legumes and tender grass. When planting forage grass, we should not only consider the trampling resistance of forage grass, but also fully consider the feeding habits of chickens, and increase the planting ratio of leguminous and tender grass. The grass species suitable for feeding chickens are chicory, alfalfa, ryegrass, polymer grass, Chinese milk vetch, red clover, white clover and Ixeris petiolata.
4 ? Reproductive density
According to the content of nitrogen, phosphorus and other substances discharged by chickens and the self-purification ability of forest soil, the breeding density of chickens under the forest can be determined.
Under the premise of not destroying the soil environment and realizing a good ecological cycle, it is appropriate to stock 5 chickens per 667 m2 forest land. This is the stocking density determined according to the amount of nitrogen and phosphorus discharged from chicken manure.
5 ? Matters needing attention
In addition to the management of raising chickens under the forest, it is necessary to coordinate the relationship between farming and ecological environment in order to make the aquaculture industry develop healthily and continuously. Raising chickens under the forest should make scientific and rational use of forest land resources, and should not exchange breeding benefits at the expense of ecological benefits.
When stocking under the forest, the pecking and trampling of chickens will cause mechanical damage to the vegetation under the forest. When the density of chickens in the forest is too high, when chickens scratch the roots, the roots will be exposed and cause damage. The research shows that the density of forest culture is too high, and the scratching behavior of chickens does great damage to the resources under the forest. In severe cases, nothing grows in the forest, and the land under the forest is uneven.
Under the condition of high-density culture, the discharge of manure will exceed the purification capacity of soil itself, and the soil will form a nitrogen and phosphorus enrichment area after absorbing a large amount of chicken manure. Excessive fertility of soil will destroy the ecological balance of undergrowth culture, affect the growth of trees and cause serious damage to the environment. To develop the chicken industry under forest, we must attach great importance to the influence of farming on the ecological environment of forest land.
