Description
One, the background of patent application of the present invention
(1) problem that exists during fryer is produced
1, fryer is produced the feed cost height
Fryer in 1976 needed 63 days reach 2 kilograms, along with the hereditary and selection progress, only needed 35 days, the speed development of the growth of fryer to shorten one day every year to calendar year 2001.The feed intake of fryer also significantly improves, and 7 week hen daily consumption in age material amounts reach 180 grams, and cock daily consumption material amount reaches 200 grams.Feed cost has accounted for more than 70% of fryer production cost.
2. the fryer fat deposition is many
The broiler carcass obesity is one of subject matter of facing of current and following fryer industry, causes the reason of this problem a lot, wherein heredity and nutrition and be major influence factors as effect mutually.The lipidosis of fryer body is too much, and no matter to the producer, processor, or the consumer has brought totally unfavorable negative effect, and economic loss is huge.
To fryer fat deposition rule, Chinese scholars has been carried out comparatively extensive studies.Qiu Ye levies husband (1990) and thinks that fat deposition shows as cytosis in early days, and the later stage shows as cell volume and increases, and growth of meat chicken incipient cell quantity growth is very fast, and cell volume just increases after 4 ages in week to some extent.
Address this problem and to take aggregate measures from many aspects.By the nutrition regulation measure, can reduce lipopexia effectively as improving dietary protein or amino acid levels, but being applied to production practices, this method often is restricted because of feed cost rises.It mainly is by the control feed intake that limit is raised, thereby artificially from a kind of technology of feeding of quality and quantity regulation and control chicken nutrient intake, can regulate and control equilibrium growth and the body lipidosis of poultry effectively, has been widely used in stud bird and has produced particularly meat stud bird production.
3, the distinctive disease incident height of fryer
Dorking abdominal dropsy, sudden death disease of meat chicken, fryer leg disease become three big diseases of fryer industry, broiler carcass obesity (3% abdomen fat rate is higher than indigenous chicken far away), the broiler carcass obesity is one of subject matter of facing of current and following fryer industry, cause the reason of this problem a lot, wherein heredity and nutrition and be major influence factors as effect mutually.The lipidosis of fryer body is too much, and no matter to the producer, processor, or the consumer has brought totally unfavorable negative effect, and economic loss is huge.
Fryer can suffer from the disease of two types performance heart failure, ascites and die by visitation of God syndrome.These two kinds of diseases more common and may be since the high-caliber oxygen of the quick growth needs of fryer to support the result of metabolic demand.Consumed its all energy in growth and effective food conversion, caused the shortage of other partial oxygen of fryer health, therefore, the work of its heart is more violent.Fryer grown select breeding and management very fast, causing in the heredity that its energy supplies with the mismate between organ and the energy consumption device official.Can aggravate the activity of cardiorespiratory system owing to increase fryer oxygen demand, therefore, growth can increase the risk of broiler ascites and die by visitation of God syndrome fast.
(1) dorking abdominal dropsy is in order to tackle ever-increasing work load, and the fryer hypertrophy of right heart of growth easily causes ascites fast.Dorking abdominal dropsy be mainly betide 4～6 age in week commodity for a kind of disease of fryer, it is characterized in that hypertrophy of right heart, lungs extravasated blood, liver enlargement and tangible seroperitoneum.Then, chicken is taken place in heart failure and the liver function change, seroperitoneum.Skin of abdomen reddens, and belly swells, accelerated breathing, pulmonary congestion.According to Britain fryer producer report, 1993, the incidence of broiler ascites was 1.4%, and according to research in 1996, the whole world had nearly 5% fryer that this disease is arranged, and makes it become one of fryer main causes of death.In recent years, the incidence of broiler ascites was in fact also increasing, and became and cause butchering a discarded reason of back trunk fasting.This disease mainly concentrates on and takes place cold season, and the incidence of disease can reach 10%～40%, the national incidence of disease average 4.5%.This disease already causes damage huge for feeding of broiler in case generation yields to no remedy.
Fryer exists geneogenous heart function deficiency, this with in the past fryer breeding work in only pay attention to growth of meat chicken speed, and ignored the fryer cardiac function is cultivated, cause fryer itself to exist congenital left ventricular function deficiency.Its cardiac index (per minute flows through the blood of kg body weight), blood oxygen transport index (freight volume of per minute kg body weight oxygen) extremely significantly reduce.The surperficial healthy fryer of research report is arranged on the other hand, and its right heart and left ventricle structure normal rate only account for 34% and 61% respectively.
(2) sudden death disease of meat chicken is in Europe, and the incidence of fryer die by visitation of God syndrome is 0.1-3%.Britain fryer producer report, incidence in 1993 is 0.8%.The die by visitation of God syndrome is a kind of acute heart failure disease, and main influence is the male fryer of growth fast.The fryer body condition is generally good during morbidity, suffers from chicken and pats wing suddenly, and disequilibrium is told sound sometimes and come, and to crestal surface or fall down in the side and dead, these are everlasting and take place in 1 minute.Though this syndrome is very short from occurring to the dead time, cause very big infringement still for the animal welfare of fryer.
(3) the sick shank illness of leg is a side effect selecting breeding to bring with walking lamely, and also is a reason that causes fryer welfare problem.Nineteen ninety for the initial stage, the scientists study of the animal doctor of Univ. of Bristol system a kind of " gait scoring " method (GS), be used for evaluating the locomotor activity and the limping situation of commercial meat bird.According to this methods of marking, be assessed as GS 0 and show that fryer has normal locomotor activity, GS 3 shows tangible abnormal gait, influences the mobility of fryer, and GS 5 shows that fryer can not walk fully.The result almost have 26% be examined fryer be assessed as GS3 or more than, therefore can think that fryer suffers from painful and walk lamely.The shank illness is a main cause of fryer welfare difference.Gait scoring studies have shown that have a large amount of fryer locomotor activities impaired, and shows and be assessed as GS 3 or above fryer has pain or uncomfortable problem.
Fryer shank illness is to select the result of breeding to a great extent, and growth fraction fryer more slowly is lower than the fryer limping incidence of growth fast.The animal doctor of Univ. of Bristol system to comprise commodity grow fast fryer, be suitable for freely putting in a suitable place to breed the mode growth fraction slowly 13 fryer strains of fryer and traditional category fryer study and think that fast growth is to cause walking lamely most important factor.
Though it is generally acknowledged, many shank illness all since modern growth of meat chicken speed cause soon,, between different fryer strains, very big difference is arranged also.Gait scoring to 4 commercial meat bird strains of generally using in European Union and the whole world relatively finds the difference that surpasses 0.5 gait scoring unit is arranged, even the body weight of fryer is identical also variant in two of these fryer strains.This bigger difference just causes owing to heredity, and management only plays a part very little for improving the shank illness.Fryer breeding company can be with selecting to improve shank intensity and locomotor activity and comparatively fast being inclined to the animal welfare that improves fryer with reversing the speed of growth.Calendar year 2001, of carrying out of Holland studies show that, can reduce the speed of growth so that fryer at 56 days rather than reached identical slaughter weight at 42 days, makes growth time prolong for 2 weeks.Regrettably, fryer breeding company still is being devoted to study the speed of growth that how to improve constantly fryer.Scientist according to breeding company estimates, by 2007, fryer will reach 3.0kg heavy (1999 be about 2.6kg) at 42 ages in days, only just can make body weight reach 2kg with 33 days.Fears are entertained that proceeds the shank illness that such selection breeding will make fryer and is becoming more serious in the future.
4, fryer is to the neurological susceptibility of disease
Evidence suggests, fryer is grown and the breeding of high feed conversion rate selects to have reduced the immunity of fryer to disease fast.Have been found that when contact infection the fryer antibody response that the breeding of growing is fast selected is lower.Carry out in Israel one about different fryer strains immunoreactive test find that 40% growth fast, heavier fryer death when ehec infection are arranged, and growth fraction more slowly the kind death rate have only 8-20%.Growth is also relevant with the cellulitis incidence height of modern feeding of broiler field fast.Cellulitis is by bacterial a kind of diseases such as Escherichia coli, it is characterized in that the skin infection surface scratches.In addition, people find that also quick fryer of growing also increases the neurological susceptibility of various non-infective diseases.
(2) related measure that adopts at present
Studies show that affranchise after the raising this feeding manner of searching for food of the limit that fryer is carried out appropriateness in early days can not only reduce the death rate of fryer effectively, and the fat deposition of fryer is also had certain influence.Zhong etc. (1995) find to raise in 7～12 ages in days limit, to male and female chick fertilizer degree and body weight generation influence in various degree.Limit is raised and is made the heavy and body weight reduction of female chick 49 age in days abdomen fat, and to the not influence of public chick, in vitro test proves that limit is raised fatty synthesis rate is reduced, and adipocyte is diminished, and finally makes the abdominal fat weight reduction.Santoso etc. (2001) think that early the time limit raises cock body protein content is increased, and body fat content reduces, and hen body fat and body protein content are reduced.Arafa etc. (1983) press the energy of free choice feeding g0% and supply with the growth chicken, and live body is heavily reduced to 94% of free choice feeding as a result, and carcass heavily reduces by 5%, and abdomen fat content reduces by 20%, and edible part weight does not reduce.Arafa etc. (1983) point out that the energy intake of fryer reduces 19% among the 10d before listing, and body weight only descends 7%, and neat percentage does not change, and abdominal cavity fat descends 50% approximately, and feed conversion rate also has raising.
(2001) such as the ox leaf of bamboves discover early stage short-term (1,2,3 days) limit and raise incidence and the general mortality rate that (50%) not only can reduce some metabolic diseases such as legs and feet disease, sudden death disease, the ascites symptoms incidence of disease, and time limit morning of finding to reach certain intensity raises and can effectively reduce accumulating of fryer body fat, thereby reduce fertile degree, the broiler carcass of producing is thinner.The test of Sugeta et al (2002) also leads to the same conclusion, yet that limit is raised chicken is but low than the weightening finish of the chicken of free choice feeding.But Summers et al (1990), Giachetto (2003), Jones (1992) find limit and raise back broiler carcass fat content marked change does not take place that evidence time limit morning raises with energy level and reduces the deposition that can not reduce the fryer body fat.And affranchise after the raising stomach fat deposition of searching for food of Fontana et al (1992) report limit is more.Also have report to think that limit is raised and improved feed efficiency, but compensatory growth makes the content of stomach fat obviously increase (Lippens, 2000).More than research all is to carry out after early stage short-term limit raises with fast large-scale fryer, and the impact effect of back fat deposition of searching for food affranchises.Body fat deposition whether can reduce fryer and deliver for sale the time that affranchising after the short-term of fryer limit is raised searches for food is still waiting further research.
