Description

Soil chicken coop supports feed formula

the application is the applying date is on January 21st, 2014, and application number is 2014100260386, and invention and created name is: the divisional application of native chicken coop breeding method and feed formula.

Technical field

The invention belongs to native chicken cultural technique field.Particularly relate to a kind of native chicken coop breeding method and feed formula thereof.

Background technology

Soil chicken also cries hen, stupid chicken, is the Local chicken breeds that China working people cultivates in long-term production practices.Relative to traditional commercial chicken, native chicken has crude feed tolerance, easily raises, meat good (the thin meat of bone is thick, skin is thin, meat is soft, aromatic strongly fragrant, the comprehensive nutrition of taste), the excellent feature of product quality.Therefore, native chicken consumption market sharply expands in recent years, and vigorous pace appears in cultivation, and raising quantity is in rising trend.Relative to modern layer breeding, the production model of putting in a suitable place to breed is raised in traditional many employings of native fowl raising scattered, requires lower in cultivation feeding process to hen house, feed nutrition, staffing etc.But along with the expansion of native fowl raising scale, raise stocking model Problems existing scattered and day by day manifest, main manifestations has:

The first, simply extensive stocking model of raising scattered makes the production of native chicken face serious control and prevention of disease and security risk.Domestic native chicken cultivation is raised mainly with small family, the feeding manner of decentralized management is main, hen house used mostly is simple and easy room, insulation heatstroke prevention is lacked in house, ventilation, the facilities and equipment that control and prevention of disease etc. are relevant, soil chicken produces and is subject to external environmental interference, both have impact on the performance of native chicken production performance, also make native chicken cultivate and face serious disease risks, especially in the area that epidemic disease season occurred frequently and epidemic disease take place frequently, the mode of raising scattered can make native chicken culture diseases to control cost increase, product safety is on the hazard, may produce domestic tradition soil chicken of beginning to take shape and bring extinction.Meanwhile, due to raiser's relative distribution, be difficult to effective supervision, add upper part peasant household and lack cultural technique, safe production awareness is not strong, may occur abuse of antibiotics, privately add the problems such as forbidden drug, have a strong impact on quality and the safety of native chicken product.

The second, traditional pattern of raising scattered causes the serious human and material resources wasting of resources, brings hidden danger also to increasingly serious ecological environment security simultaneously, the long term growth of the native chicken culture benefit of serious restriction and high-quality soil chicken industry.In the situation of raising scattered every mu can compost chicken about 50 ~ 300, the plant of about 5000 needs the special keeper of outfit 2 ~ 3 to manage, this with day by day deficient land resource, the human cost that rises steadily obviously is extremely unconformable.And, because common raiser lacks the professional knowledge of native fowl raising, blindly expand raising scale, increase stocking density, make the limit that the cultivation quantity of native chicken in culture zone can carry far beyond breeding facility, cause that cultivation on-site mosquitos and flies grows, soil compaction, pollution of waterhead, degradation serious problems under product quality, affect the sustainable development of Production of Livestock and Poultry.

Three, extensive feeding and management method and easy feed processing technology can not guarantee the quality of native chicken product.Raise native chicken scattered mainly through extra-nutritions such as cereal of feeding, corn, wheats, the worm, grass, sandstone etc. that also utilize nature natural as nutritional supplementation simultaneously.But this ingestion types, with very big randomness, makes native chicken production disengaging feed supervision, can not ensure native chicken product safety.Point out after having Taiwan's scholars research, the pollutant dioxin contained in " Countryside Egg " exceeds five times than common egg.Therefore, the native chicken product produced under traditional mode be not people the imagination such quality superior.Meanwhile, the mode of production that native chicken is raised scattered brings the inconvenience of feeding and management, adds production difficulty, reduces production efficiency.Therefore, seeking a kind of feeding manner being more applicable to the production of native chicken is one of vital task of native chicken long term growth.

It is a kind of very ripe aquaculture model during domestic and international laying hen produces that laying hen is raised in cages, it relies on outstanding high-yield egg chicken kind both at home and abroad, coordinate intensive Rearing facility equipment, efficiently feed nutrition technology and perfect technique of management and administration that the laying hen level of production is fully enhanced, ensure that the needs of laying hen High-efficient Production, meet the requirement that people keep the safety in production to meat egg product.Batterylaying pattern, relative to the native fowl raising of tradition, has following advantage: 1 production efficiency is high, and feeding and management is convenient.Laying hen is raised in cages and can meet hen house compost chicken 3000-50000 scale only, can ensure that less manpower just can complete all processes of laying hen production, substantially increase the utilization ratio of human and material resources resource, and, owing to producing Relatively centralized, convenient management, can ensure to monitor the links in production at any time, ensure that product quality, maintain food security.2 laying rate of laying hen are high, and persistence is good.Batterylaying due to supporting a complete set of insulation, heat insulation, search for food, water system, to feed perfect compound feed, and manage according to the production specification of standard, meet Egg Production of Laying Hens and produce meat needs, the potentiality of laying eggs of laying hen are played comprehensively, improve Egg Production of Laying Hens level, therefore, this aquaculture model is used widely in the whole nation comprehensively.The resource utilization of raising existence in view of current China soil chicken scattered is low, the present situation that production efficiency is low, the deficiency that the advanced production technology that the existing laying hen of abundant reference is raised in cages is raised scattered to make up native chicken, the production performance of the native chicken of more effective performance, solves China soil chicken and produces the medium-term and long-term technical barrier faced.

Summary of the invention

The technical solution used in the present invention is: guaranteeing to raise in cages on the basis of native chicken egg product quality, in conjunction with the Physiology and biochemistry feature of native chicken of raising in cages, by supporting the technical problems such as feed formula be optimized integrated to the installations and facilities relating to the selection of the native chicken breed that native chicken coop is supported, native chicken produces, native chicken dietary nutritional standard, native chicken coop, to promote native chicken production performance further, ensure native chicken egg product quality, improve native chicken culture benefit.

In the selection of native chicken breed of raising in cages, by carrying out com-parison and analysis to the industry characteristics of native chicken breed, in conjunction with domestic native chicken consumer market demand and the physiological property of native chicken self of raising in cages, the kind of native chicken of determining to raise in cages.Native chicken of raising in cages should have following feature: 1, this native chicken breed should have lay eggs preferably, meat production, the needs of native chicken consumption market can be met.2, this native chicken breed should be able to adapt to local natural environmental condition.3, this native chicken breed answers disposition docile, has stronger resisting stress characteristic, can meet the requirement of raising in cages.4, this native chicken breed should be equipped with comparatively perfect production specifications, and what can ensure that native chicken produces carries out smoothly.Namely require raise in cages native chicken breed should have small, lay heavily, feed consumption are few, egg meat is of fine quality, premunition is strong, survival rate is high, be applicable to features such as raising in cages.In recent years, due to people's doting on green product, egg with green shell becomes a bright spot on consumption market, and the green shell Countryside Egg produced by native chicken is subject to pursuing of consumer especially, and selling price rising all the way, market potential sharply expands.Cultivate green shell soil laying hen and become the new way to become rich that native chicken produces.Through carrying out data acquisition contrast to the native chicken breed of part, determine that New Jianghan chicken green shell system is as native chicken breed of raising in cages.

Under normal circumstances, native chicken compares adaptation for the condition of raising scattered, but under cage conditions, because activity space is relatively little, the adaptability of native chicken in cage reduces, and the stress reaction of environmental change to external world strengthens, and due to cultivation density relatively high, require also will improve to corresponding auxiliary facility.Therefore, native chicken coop is supported and in the requirement of installations and facilities, is first higher than traditional native chicken raises scattered.Thus, in order to ensure product quality, native chicken coop support raise in cages relative to laying hen stricter in breeding environment, control measures.So native chicken coop is supported to be needed to integrate the lesson of raising native chicken experience and high yield scattered and raising in cages, and finally reaches and has both produced qualified native chicken product, can give full play to again the object of native chicken potentiality.Therefore, we are on the raising hen house of commodity egg and the basis of cage tool (390 type) equipment, are optimized improvement to the temperature-controlling system of raising in cages in the management of native fowl raising, water system, spraying disinfection system.

To raise in cages native hen house temperature-controlling system, by the layout to hen house inside, hen house window (layout, area) the design parameter aspect such as setting, air exhauster, cascade, cage tool improve, guarantee that in native hen house, temperature controls between 10-28 DEG C throughout the year, humidity 70-80%, the basic physiological requirements meeting native chicken of raising in cages.Specifically be set to: hen house is semi-enclosed hen house, every hen house establishes 2 row chicken coop, 3 perpendicular passageways, 2 transverse aisles, the long 85-90 rice of hen house, and wherein, transverse aisle is wide 2 meters, and rear transverse aisle is wide 1.5 meters; Hen house inner width 7.5-8 rice, wherein dropping pit is wide 1.8 meters, and middle perpendicular passageway is wide 1.5 meters, and it is wide each 1 meter that passageway is erected on both sides, dropping pit anterior dark 20-25 centimetre, the dark 30-35 centimetre in rear portion, chicken coop adopts 390 types, cage tool is 3 layers of staged, is placed in above dropping pit, often organizes raising layer 90; Hen house side walls is provided with window, and hen house window adopts double glazing, and window maintains an equal level along a little more than cage upper end, hen house top or with cage upper end, chicken coop top, window height 1-1.5 rice, and wide 1.1-1.5 rice, fills 1 every 3-5 meter ampere; Establish blower fan in hen house, 4 of the fan blade diameter 1.5 meters of blower fan, 2 of fan blade diameter 0.8 meter, be arranged on and just erect on the rear wall in passageway to hen house, the cage of blower fan axle center and second layer chicken coop holds flat, and blower fan is arranged as greatly-and little-large-large-little-large; Outside hen house, front end increasing repaiies side room for hanging cascade, the long 11-13 rice of side room, high 2-3 rice, wide 1.5-2 rice, and the pond of 1 1-1.5 cubic meter is built by central authorities, side room ground 20-30 centimetre lower than ground level in hen house.

To raise in cages native hen house water system: neck sheds feathers and has a strong impact on raise in cages native chicken outward appearance and carcass quality, is the key factor causing superseded native chicken sales difficulty.Observe and find, general cultivation is all to be installed on by nipple of drinking water in cage directly over chicken health to, chicken when drinking water, and water droplet can flow out from the corners of the mouth, makes the feather of chicken neck moistening, add search for food, rub, the reason such as fight, finally cause native chicken neck plumage to come off.Based on this, the position of nipple of drinking water in cage is changed, by constantly contrasting debugging, determining the best position of drinking-water nipple cage 4.5-6 centimeters in front of the door before distance chicken coop, and having the drift angle of inside 45 °.

For reducing the stress reaction of native chicken in cage, reducing the fight between native chicken, adjusting the stocking density of every cage soil chicken, through repeatedly trying to support, determining that the best stocking density keeping the production of native chicken and product quality is 2/cage.

Spraying disinfection system, decontamination system equipment is made up of tank, high-pressure hydraulic pump, conveyance conduit, shower nozzle, and each equipment room is connected successively, and tank, high-pressure hydraulic pump are placed in outside breeding house, shower nozzle is arranged on 40-60 centimeters directly over chicken coop, 1.5-2 rice in interval between each shower nozzle; The service routine of disinfecting drug is: sterilization adopts the circulation of chlorine, fluorine, bases to carry out, 1 time weekly, each 5 minutes.

In native chicken feed configuration of raising in cages: in order to better play the production performance of native chicken, improve the quality of Countryside Egg product, the feature of and sensitiveness lower for native chicken efficiency of feed utilization of raising in cages, in conjunction with New Jianghan chicken with reference to trophic level, by select DIFFERENT FEED daily ration to the adolescence under cage conditions, laying period New Jianghan chicken carry out native chicken feed additive contrast test, filter out applicable native fowl raising adolescence and laying period soil chicken feed additive.With reference to the nutrient demand (seeing the following form 1) that New Jianghan chicken each stage is main,

Adopt the raw materials such as corn, dregs of beans, the dish dregs of rice, wheat bran, need to coordinate to the energy in native fowl raising, protein, essential amino acid, mineral matter.Meanwhile, in order to satisfied native chicken nutritional need, ensure native chicken product quality, also need to carry out nutritional supplementation by adding greenfeed, feed addictive, sandstone etc., the production performance accomplishing to improve New Jianghan chicken in turn ensure that the security of New Jianghan chicken egg product.It is that mode by floor husbandry is carried out that soil chicken broods, and feed formulation can directly use for reference laying hens in brooding period nutritional need.Namely proceed in cage in the adolescence and raise, therefore, the key that native chicken coop is supported solves the feed nutrition of native chicken between adolescence and laying period.In view of this, we only support feed formula to the native chicken coop of adolescence and laying period and screen, specific as follows:
