Abstract
The invention discloses an ecological breeding method capable of improving disease resistance of chickens, which comprises the steps of establishing a farm, daily hierarchical management, free-range feeding and epidemic disease control, wherein the free-range feeding frame is adopted to feed freely, prepare special feed, and regularly check and disinfect.
Description
Technical Field
The invention relates to a breeding method, in particular to an ecological breeding method capable of improving disease resistance of chickens.
Background
Poultry refers to birds that are artificially housed, primarily for the purpose of obtaining their meat, eggs and feathers, and also have other uses. Typically animals of the Phasianidae and Anatidae families, such as chickens, ducks, geese, etc., and birds of other families, such as turkeys, pigeons, quails and various birds with a whizzy bird. Chickens are a species of poultry, and domestic chickens originate from wild jungle fowl and have a domestication history of at least about 4000 years, but chicken and eggs are not mass produced commodities until around 1800 years. The chicken may be turkey, black-bone chicken, pheasant, etc. The chicken has good taste and rich nutrition. Most of the nutrients of chicken are protein and fat, but the chicken is lack of calcium, iron, carotene, thiamine, riboflavin, nicotinic acid, various vitamins and crude fiber, and if the chicken is taken as staple food for a long time and other melons, fruits, vegetables and grains are not taken, the body is sub-healthy.
The ecological breeding method is to improve the breeding water quality and ecological environment by utilizing pollution-free water areas such as lakes, reservoirs, rivers and natural baits or applying ecological technical measures, to breed and breed according to a specific breeding mode, to put in pollution-free feed, and to not apply fertilizers and sprinkle medicines, and to produce pollution-free green food and organic food. The livestock and poultry products of ecological breeding are popular with consumers because of high quality and good taste.
With social progress and scientific development, people seek higher and higher delicious food and safety, chicken is used as indispensable meat on daily dining tables of people, the demand is increased year by year, but traditional chicken is delicious in meat quality and safe and relieved but is not required to be supplied, the current chicken farm meets the supply demand, but the taste is not good, some black-heart merchants seek maximum benefit and inject hormones into the chicken, so that the chicken food safety problem is caused, the ecological breeding advocated at present can not only improve the yield, but also is purely natural and pollution-free, but various diseases can be infected in the ecological breeding process of the chicken, so that the breeding of the chicken is influenced, and the death of large-scale chicken is caused seriously, therefore, the invention provides an ecological breeding method capable of improving the disease resistance of the chicken, so as to solve the problems provided in the background technology
Disclosure of Invention
The invention aims to provide an ecological breeding method capable of improving disease resistance of chickens, so as to solve the problems in the background technology.
In order to achieve the purpose, the invention provides the following technical scheme:
an ecological breeding method capable of improving disease resistance of chickens comprises the following steps:
(1) Establishing a farm
A. Site selection: selecting places with little pollution, enough water sources and convenient traffic, nearby forest lands, grasslands, barren mountains, rice fields or vegetable greenhouses and the like as farms;
B. and (3) colony house: b, selecting a place with a higher terrain in the breeding area selected in the step A as a henhouse;
C. and (3) channel repairing and ventilation: building drainage ditches around the henhouse, forming a plurality of ventilation openings on the wall surface of the henhouse, and additionally installing fans;
D. establishing a fence: establishing a fence or a purse net at the edge of the culture site;
(2) Daily hierarchical management
A. Brooding: the chicks are just hatched, are sensitive to the environment, have poor resistance and cannot be directly put in the breeding, and need to be managed and raised in a centralized manner at this stage;
B. and (3) middle and large chickens: the outdoor breeding time of the chicks is slowly increased to enable the chicks to gradually adapt to the environment, one person scatters feed on the road to open a way, the feeding amount is controlled, and the chicks are guided to find food in the field;
