Breeding techniques and methods of free-range chickens in the mountains, thank you!

1, select fine varieties. Excellent breeds are the basis for raising high-quality broilers. We should choose local famous varieties with thin skin and fine bones, plump muscles, delicious meat, strong resistance and small and medium-sized color feathers.

2. Pay attention to grazing. Grazing is one of the important measures to improve the meat quality of broilers. The technical requirements for brooding of high-quality free-range chickens are the same as those for fast-growing broilers. After brooding in the brooding room for about 30 days, it will be transferred to the greenhouse for breeding. Generally, grazing begins in 30 days in summer, 45 days in spring and autumn and 50-60 days in winter.

It is best to choose bamboo gardens, orchards, tea gardens, mulberry gardens and other places with high and dry terrain, sheltered from the wind and sunny, quiet environment, convenient drinking, no pollution and no animal harm. Chickens can not only eat pests and weeds in the above four gardens, but also fertilize them. A sandpit can be set up in the grazing land for chickens to bathe in the sand. It is also necessary to build a straw shed or plastic shed to shelter from rain, sun and cold.

Broilers come out early and come back late, and the grazing density is 50 ~ 70/mu, and the size of each group is about 500. In order to prevent chickens from getting lost or hurting nearby crops, fences can be set up in the pasture until they are sold. Strengthening grazing can improve the compactness of chickens and promote their physique and feathers to be tight and bright; You can also eat grass, grass seeds, dead leaves, flies and so on. Save feed and improve meat quality.

Conditional can put a batch of chickens in different places, which is not only conducive to disease prevention, but also conducive to chicken foraging.

3. Skillful feeding. Feed is an important factor affecting meat quality. High-quality native chickens should be fed with digestible and nutritious full-price feed for chicks during the brooding period. Because of its slow growth rate, the crude protein content in the feed is 2% lower than that in the complete feed for fast-growing broilers, so it is necessary to eat more meals in small quantities to promote the growth and development of chicks.

In order to improve the meat quality and reduce the feed cost, more green feed, agricultural and sideline products and coarse grains should be fed during breeding and grazing, and the compound feed should be supplemented after returning home at night. 0 ~ 2 weeks before 65438+ slaughter, if the chicken is thin, the feeding amount of compound feed can be increased and grazing can be restricted for moderate fattening.

Animal feed such as silkworm chrysalis, fish meal and meat meal should not be added to the compound feed in the middle and late stage. Rapeseed meal, cottonseed meal and other feeds that have adverse effects on meat quality and meat color should be limited. Artificial synthetic pigments, chemically synthesized non-nutritional additives and drugs shall not be added. Natural substances such as orange peel powder, pine needle powder, garlic, ginger, fennel, cinnamon and tea powder should be properly added to change the meat color, improve the meat quality and increase the umami flavor.

4. Strict epidemic prevention. Doing a good job in epidemic prevention and disease elimination is an important guarantee for raising high-quality free-range chickens. In general, free-range chickens have strong disease resistance, and the incidence rate is less than that of large-scale broilers in captivity. However, due to the long feeding period and grazing in the wild, there are many opportunities to contact pathogens. We must do a good job in sanitation, disinfection and epidemic prevention according to the requirements of raising chickens, and we must not relax.

5, timely sales. Suitable feeding period is an important link to improve meat quality. When the feeding period is too short, the chicken has too much water content, insufficient accumulation of nutrients, less umami and aromatic substances, poor meat quality and poor taste, which can not meet the standards of high-quality chicken; The feeding cycle is too long, the muscle fiber is too old, and the feeding cost is too high and uneconomical.

Extended data

The sexual maturity time of native chicken is late, which is greatly influenced by the season. The chickens raised in spring mature early, and the chickens raised in autumn start to produce late, generally, the age is 150 ~ 180 days.

Under natural conditions, the laying performance of native chickens is seasonal, mainly affected by nutrition, temperature and light, and the laying rate is high in spring and autumn every year. In winter, when the light time is shortened, the temperature drops and the nutrition supply is insufficient, the spawning will stop. Therefore, the annual egg production of native chickens is low, generally only 100 ~ 130.

Free-range chickens belong to mountainous areas, and there are no industrial, mining and chemical enterprises around them, and there is no air, water and soil pollution. The chickens raised in this environment are even better than those raised by farmers.

Native chickens are scattered on the hillside, where plants are flourishing. Native chickens play and eat in the forest all day and enjoy enough exercise and sunshine. The resistance of this native chicken is much higher than that of foreign chickens or indoor chickens raised indoors, so there is no need to feed antibiotics and there will be no mass death. Many soil eggs are laid directly in the forest, and the workload of picking up soil eggs is also great.
