Description
Technical field
The invention belongs to field of fodder, and in particular to a kind of feed and its preparation side for ensureing that broiler chicks efficient and healthful produces
Method.
Background technique
It is proposed the necessity of broiler chicken early nutrition
In practical poultry production, the shell time that goes out of chick is more than 24-48h, and can after most of chick goes out shell
Leave incubator.Out the processing after shell and to farm transport also need other setting to stay the time, longest can reach 72h.At this
In one period, poultry usually neither searches for food nor drinks water.Although internal remaining yolk can maintain the energy balance of poultry, just
Shell chick digests and assimilates food out and the ability of moisture is limited, causes chick to employ intracorporal storage, mainly employs subcutaneous fat
With the deposit in liver, it is also possible to musculature is employed, to maintain metabolism and promote the maturation of thermoregulatory system, this
Process occurs mainly in chick and goes out initial after shell 10 days.
Chick early development feature
Heredity selection makes the speed of growth of poultry and feed conversion rate be greatly improved.Along with the choosing of genetic breeding
Process is selected, the structure and function of poultry gastrointestinal tract also has changed a lot.Studies have shown that the variation and feeding of gastrointestinal system
Expect that the selection in conversion ratio direction is closely related, this shows especially pronounced on Broiler chicks.Entire life is grown in due to the 1st week
The life period occupies biggish specific gravity, therefore the growth that poultry starts the 1st week in life is more important, especially to butcher's beast.
Lilia (1983) proposes that the final growth of poultry is direct to the development of the system of body other parts offer nutritional substrate with those
Proportional relationship, especially gastrointestinal tract and cardiovascular system.
From 0 to the 10 Day-old Broiler Chickens speed of growth is constantly accelerated, and about increases by 20% daily when reaching peak.In order to play heredity
Potentiality, birds must adapt to rapidly the digestion of exogenous diet, and the nutrient in external source diet passes through small intestinal absorption, energy
Mainly provided by carbohydrate.The factor for influencing early growth speed may include the matter of yolk bag residual quantity, feed and water
Amount disappears with intake, the level of pancreatin and intestines enzyme, the surface area of gastrointestinal tract, nutrient transport vehicle and whole nutrients
Rate.Another process that must be taken into consideration is fundamental shifts of the energetic supersession from fat to carbohydrate.Poult cannot with
The identical efficiency of adult poultry utilizes certain ingredients such as tallow, and this point has been proven.What it is with eupepsy raising is
The variation of body developmentally includes that pancreatin and intestinal enzymes secretion increase entirely gastral surface area increase and nutrient transhipment load
The variation of body.
1, remaining yolk
The chick for just going out shell experienced an essence variation in the supply and metabolism of nutrient.In the embryo hatching phase,
Egg fat transmits the energy demand of supply chick from yolk bag through blood.With closing on for broken shell age in days, liver of the glycogen in embryo
Dirty middle accumulation and the energy demand for being used for broken shell process.In addition.Fat is transferred to liver, and yolk bag internalization is wrapped in chick
In vivo.Energy needed for this kind of remnants yolk fat can be used for providing chick.But its ingredient shows this kind of rouge for cell membrane knot
Structure and development of central nervous system it is more efficient.Therefore, these can be saved by providing energy with the carbohydrate versions of feeding
Unsaturated fatty acid for the immobilized artificial membrane of neoblast to synthesize.
Yolk residual volume is very limited.In fact, the energy obtained from egg fat is not enough to maintain chick for 24 hours.Going out
The 1st day after shell, about 80% remaining egg fat was transported to tissue, remaining less than 10% two days later.Equally, in life
First 2 days, the protein in yolk bag more than half is transitted to chick, almost without protein residue after 4 days.It is this containing
The protein of a large amount of maternal antibodies is better than for providing passively immunoprotection and is degraded into amino acid and is utilized.If at chick
Among hungry danger, perhaps maternal antibody plays trophism, but this is apparently not ideal state, because this makes chick in life
The last fortnight of life loses protection to the invasion of cause of disease.
2, the intake of feed and water
Although remaining fat rich in yolk.Also there is fatty storage in liver, but postpone the confession of feed and water
To the peak mortality for being but related to early stage, especially for chick.Although nearest evidence shows that some remaining yolk can lead to
Cross yolk stalk enter small intestine but research discovery yolk bag appearance to the importance of gastrointestinal development be unable to catch up with feed feeding.Cause
This obtains and absorbs rapidly feed and water either to the direct development of tract, or to long-term survival and production performance
It is crucial.
Food and drinking-water are opened in delay to generate long-term negative effect to the growth of chick.In practice, chick is placed in hatching
In device up to 48h or stay always to 90% chick go out shell death rate compared with transfer after shell out at once is higher, birth weight compared with
Low, growth performance is poor.Also immune state can be jeopardized by having one to put in a suitable place to breed researches show that delay chick.3d after cutting off yolk bag.
Although intestines weight and liver are substantially reduced again, the feeding experiment or fasting test to chick all show that feeding nutrient is initial to poultry
The facilitation of weight gain is more more valuable than residual yolk.
3, digestive ferment
The metabolic alterations of the another aspect occurred with hatching process are that the intake of nutrient is changed by blood delivery form
At feeding form.The nutritional requirement of feeding form generates digestive ferment and macromolecular substances is degraded to the absorbed small molecule of energy.Disappear
Change enzyme and results from the incubation period for the first time.See that digestion enzyme level improves in shell rear surface out, but the digestive ferment of every gram of feed food-intake
Concentration does not change.In shell out, the Disacchridase Activities of the feed although chick was never searched for food, its small intestinal mucosa are horizontal
It is very high.Nitsan etc. has studied the digestion enzyme level of the low and high selected strain of 8 week old weight, finds the pancreas of high weight strain chick
Island element and amylase level are above under-weight strain in 3 ages in days and 9 ages in days.Murakami etc. (1992) proposes enzyme relative to disappearing
The change for changing amount of substrate may cause the 1st week growth differences, or even the growth of limitation the 1st week, and this change is and the age
It is related.Chick is that pancreatin secretion is more to the reaction of forced feeding.The increase of adult poultry feed intake, which need to be used, secretes more pancreas
Enzyme makes up, this shows that perhaps digest enzyme level cannot limit life growth in the 1st week, but its horizontal and specific activity Ying Fei
Very close to requirement, and synthesis and increasing sharply for secretion must keep up with the increased paces of feed intake.
4, the surface area of gastrointestinal tract
It is some other research shows that gastronintestinal system physical factor, such as the effect phase of enteron aisle length and surface area and digestive ferment
Than the growth for being more likely to limitation early stage.For example, Ritz etc. obtains the diet of poultry feeding addition amylase, early growth is accelerated former
Because being the appearance due to enzyme in diet so that the surface area absorbed increases.To studying for heavy weight selected strain, show
Light weight strain shows relatively low small intestine growth, shorter intestinal villus compared with weight weight strain or fast-growth strain
With lower enterocyte density.Gastrointestinal tract surface area can limit growth, with to relatively lighter weight and feed conversion rate
Breeding, the intestinal mucosa of the big broiler chicken of 6 week old declining really with respect to gross weight.Consequence caused by chick gastrointestinal tract surface area is small is perhaps
It can be improved by slower feed percent of pass, but this also results in relatively low feed intake.Although should be noted that broiler chicken exists
Usually showed after shell out feed consumption increase, but it is initial for 24 hours.Even being freely eaten also can not change under weight
Drop.
At the 1st week of life cycle, it can be seen that nutrition supply system, that is, gastronintestinal system of growth of animal is absolute and relative
Weight is increasing.Really, the preceding 5d of life, or even in the case where fasting, the absolute growth of small intestine also increases at any time.So
And the intestines relative to weight increase again and the increase of villus length and enteron aisle diameter is required and searched for food with beak.
5, nutrient movement system
The amino acid before shell on intestinal epithelial cell membrane and hexose transport system develop quickly and in the 1st week density of life out
Increase.Movement system seems not limit early growth, but turn-over capacity needs are adjusted to matching or defeated just over nutrient
Enter amount.Recent evidence show that perhaps the transhipment amount of glucose is limited, the especially poultry to fast-growth breeding.Due to
Poultry intestinal tract Tissue oxygen consumption, metabolic requirement and quantity of heat production are high and epithelial cell life cycle is short, and relative weight is appointed
Once general who has surrendered signifies entirely to maintain what is needed to significantly improve.
6, the digestibility of nutrient
The overall efficiency of gastro-intestinal digestion can be measured with digestion trial.The 1st week started in spite of scholar's discovery in life,
Chick all improves the digestibility of carbohydrate, protein and fat at any time, but different nutrient digestibilities is
It is different.The fat that chick is most difficult to digest is the long-chain fat of saturation.Chick and poult fat digestibility is low is reported extensively
Road, this is synthesized with mature cholate and reabsorption system is related, without being a lack of lipase.Pass through addition cholate or soybean
Lecithin can improve poultry early stage to the fatty as the low defect of tallow digestibility supports above-mentioned viewpoint of relative saturation.Relatively not
The digestibility of saturated fat such as soybean rouge is more much better than tallow and little with age increase rate.Recently to Nutrients Absorption
In research, Nov and Sklan (1995) report out the preceding 14d after shell, and the oleic acid amount through duodenal absorption does not change.At that
In item research.Fatty acid is supplemented with taurocholate capsule form.This masks the low phase with shortage cholate of chick digestibility
Pass relationship.
7, energetic supersession
Life start after initial 5d, the variation of blood lipid, lipoprotein and glucose level shows a fundamental shifts,
That is transformation of the embryonic period, embryonic phase based on fat metabolism to the chick phase based on carbohydrate metabolism.1 Japanese instar chickling carbohydrate
The importance of metabolism can be tested by oral or subcutaneous injection glucose or sucrose solution.Broiler chicken and turkey production performance mention
It is high related with the aqueous solution of perfusion glucose or sucrose.Other than perfusion glucose or sucrose, other battalion are immediately utilized
Feeding element can improve the production performance of turkey to the maximum extent.Accordingly, there exist remaining yolk perhaps to maintaining the high survival of chick
Rate is enough, but the mature of energetic supersession requires carbohydrate of searching for food as early as possible, and amino acid and other nutrients is flat
It is required for weighing to the acquisition of subsequent best production performance.
8, early nutrition and supply system: gastrointestinal tract and cardiovascular function
It early nutrition and opens food and seems most important to best production performance.Chick can be hindered by also showing delay feeding simultaneously
The maturation of system just germinates after nutrient because these systems are only searched for food.This includes to liver and pancreas in gastronintestinal system
It influences particularly evident.Intestinal growth, either villus growth or enterocyte differentiation all partial dependency feeding stimulations.Such as
Enterocinesia power, nutrition movement system, pancreatin secretion and cholate synthesis system all individual developmental in shell out.But they will reach
The level of Adult Chicken needs to search for food.If stomach and intestine supply system cannot be mature rapidly and provides required nutritional substrate to required
Organ such as muscle.So perhaps the development of these organs does not catch up with forever.Be conducive to gastronintestinal system development for early nutrition
Research shows that the absolute weight for opening the food small intestine of chicken, pancreas and liver is significantly higher than the chicken of 0~4d fasting.In order to which maximum promotes
Development of these supply systems after shell out.Nutrient must absorb as early as possible.Therefore, the supply of early nutrition element not only direct shadow
Survival rate and premunition are rung, and influences the performance of final genetic potential in organ, system and integral level.
Another supply system that animal reaches optimum growh and must develop is cardiorespiratory system.The poultry of fast-growth it is susceptible by
Heart failure caused by cardiopulmonary insufficiency and ascites symptoms.Therefore, the newborn chick cardiorespiratory system development out after shell must be at once
Start, function should be enough to support the other systems of body.One researches show that early nutritions in 0~4 age in days poult
The influence of dirty heavy and yolk bag weight as weight a part.Test chicken feeding is supplemented exclusively for the liquid nutritional that poult is prepared
Material or life preceding 4d fasting.The chicken weightlessness 1.29 of fasting after processing 4d, and the chicken weight gain 1.09 fed.Although all
The small intestine growth for all having potential nutrient but feeding chicken in the remaining yolk of test chicken is significantly higher than fasting chicken.It is interesting that
Fasting does not change the utilization rate of yolk.The absolute weight of fasting chicken with yolk shows its accelerated utilization.But the phase of the heart, lung
It is still the height for feeding chicken to weight.The relative heart weight for feeding chicken is quite stable, and the relative heart of fasting chicken focuses on fasting
Period decline, is then presented huge compensatory growth to feeding.The cardiac growth of this burst perhaps generate negative effect because
Early stage cardiac hypertrophy may be the indicator of later heart function hypoplasia and ascites symptoms.Remaining ovum is found out from these data
Huang cannot provide enough substrates and complete lasting cardiopulmonary growth；Organ such as alimentary canal is fed, the development of heart and lungs is to morning
Phase feeding is particularly sensitive.
It summarizes
In order to play the genetic potential of growth, chick must be immediately subjected to an energetic supersession and nutrient after shell out
Transformation kinetically.Perhaps, the appearance of remaining yolk is enough to maintain to survive, but is not enough to maintain optimum growh.Remaining yolk
Some ingredients if maternal antibody, cholesterol and polyunsaturated fatty acid have other functions, rather than provide nutrition to chick
Element.These compounds can be saved to synthesize for passive immunity and cell membrane by opening food early.Data shows that even 1 or 2d of delay is raised
The supply of material and water can make gastrointestinal tract, liver and pancreas early growth degradation.To various nutrients in broiler chicken early nutrition
Effect further research illustrates that growth originates in the absorption of remaining yolk, but the opposite quickly weight gain choosing of feeding of carbohydrate
The performance for the poultry growth potential educated is most important.Data shows that the initial several days remaining yolk started in life help to play
The key effect of the nutrient for supplement of searching for food keeps the utilization of protein and energy more effective.Feeding nutrition is fed to from blood to close
Key is to provide this requirement supply organ of substrate for the fast-growth of required organ such as bone and skeletal muscle.Including gastronintestinal system
Fast-growth and maturation.Cardiovascular system must develop rapidly to meet the requirement of fast-growth, because of final genetic potential
Realization rely on maintain need level more than nutrient and oxygen fast and stable supply.
The importance of chick early nutrition is widely studied in recent years, what Uni and Ferke (2004) write
Summarizing to extend to set after summarizing out shell stays the time that hair is developed and be immunized to yolk utilization, growth and gastrointestinal development, musculature
The influence educated.Improve feeding management measure, such as shorten incubator or food is opened by specific management measure in advance, or shell will be gone out
The feeding program in the ovum that connects on nutrition supply between feeding for the first time is that one kind can be eliminated and open food by delay and be drawn
The solution of the negative effect risen.Develop the opened guideway that can preferably meet the nutritional need of rigid hatch chick, also for
Solve the problems, such as that this provides another method for choice.
The importance of opened guideway:
For all young age poultry be within first week after shell out it is extremely important, between past 40 years, the listing of broiler chicken
Age in days reduces one day every year.Now initial 7d almost accounts for the 17% of entire life process in time, and in weight
On then account for the 5%~10% of final weight.In addition, 7 age in days weight seemingly its ideal fallout predictor for butchering daily weight.
Current broiler feeding scheme contain feed that house chick to 21 Japanese instar chicklings use open food daily ration, however the
In one week, the nutritional need variation of chick is exceedingly fast, so should take into account this case when preparing opened guideway.Out after shell,
A great change is switched to from the rich fatty yolk of endogenous outer using the change in nutrient source with newborn chick
Source property is rich in the feed of carbohydrate and protein.It has mentioned as discussed above, out in first after shell week, chick alimentary canal
It is subjected to morphology and physiological great change, to guarantee correctly to disappear and utilize taken in nutrient.Feeding is solid
Body feedstuff can promote these indispensable changes on the gastral morphology of chick and its secreting function.It is verified that such as
It is described previously, in actual production opening food delay will lead to chick production performance decline, as the speed of growth, immune system swash
The living, secretion of digestive ferment and allelotaxis etc..Therefore, the development and survival to commercial broiler and other poultry in first day after shell out
It is all very crucial.Top-priority early nutrition scheme first should can preferably meet just to go out shell using opened guideway
The specific needs of chick.In addition, best nutritional collocation in first week should consider contribution of the yolk on nutrient supply and not yet
The enteron aisle reached maturity utilizes the ability of exogenous feed.Ratio between constant nutrient broiler chicken is gone out the production performance after shell and
Body composition has important influence.
Out before shell/go out be after shell chick embryonic development critical period.Because it needs higher energy to confess shell mistake
Journey and basic metabolism utilize.Maintain sufficient glycogen deposit to can it is harsh go out shell process after survive and to by endogenous nutrition
It supplies particularly important to the conversion of exogenous nutrition supply.As noted previously, it is opened as caused by routine work method
Food delay, it will broiler chicken is inhibited to play the genetic potential of its production performance.These ill effects can be gone out after shell directly by chick
It connects in feeding feed and/or eliminates.However, this point is difficult to realize in view of the actual conditions of hatchery management.But it can be with
It is realized by using alternative, such as the nutritional preparation of the specific feeding system such as raw material containing specificity.Feeding method in ovum, i.e.,
To the method for entering to inject nutriment in incubation before chick goes out shell and during hatching.Many exploitations in relation to feeding program in ovum
Research has been completed, and has applied for patent (Uni the and Ferket.US patent No.: 6.592.878).What these researchers obtained
Conclusion is when embryo starts to consume amniotic fluid, it is necessary to carry out feeding in ovum.It is at this time about the 17th~18 day of chicken embryo age, because
Amniotic fluid is fallen by chicken embryo oral absorption when nearly going out shell, and therefore, nutrient is transported in the enteron aisle of chicken embryo, feeding and early stage in ovum
Feeding seems mechanism having the same on improving broiler chicken later period production performance.Amnion content enters the enteron aisle of chicken embryo.It can pierce
Swash the intestinal growth in period in ovum.And out after shell feeding will further stimulating gastrointestinal road development.In addition, feeding and going out in ovum
Early stage after shell feeds the chick weight after can improving at least to go out shell before 35d.Therefore, existing problem is that feeding is no in ovum
The portrait or photograph of the deceased is rung after generating to the initial beneficial effect fed after shell out, is after being based on shell to the arguement that this rear portrait or photograph of the deceased is rung
Muscle growth situation.The mitotic activity of satellite cell is dropped in chick period from prenatal to postnatal highest, and with the increase of age in days
It is low.The proliferation that can induce sarcoblast is fed in ovum, and can be deposited out and be generated a large amount of satellite cell in the early development after shell.
In conventional broiler production, due to going out the span of shell time, other operations after shell out, are such as selected, property in addition
Not Jian Ding and the transport etc. to broiler breeding field, hatch chick open food the time to postpone to be up to 72h.A large amount of documents and materials are aobvious
Show, such early stage, which stops eating, to generate adverse effect to the development of broiler chicken and the production performance in later period.In addition, when going out shell of incubation period
Between and out the span of shell be two can aggravate delay open food adverse effect an important factor for.Multiple factors or technology may help
In mitigation these problems:
(1) it uses in the ovum containing ideal nutritional composition and feeds nutritional preparation.Shell can be made up out and open the nutrition between food
Notch.
(2) using in hatchery and/or the specified conditions even in incubator, the shortening incubation period.
(3) it is opened the food time using the shortening of specific management measure, i.e., for going out the new technology of shell phase and early stage feeding.Such as
Oasis nutritional preparation.
(4) needs for stopping the rigid hatch chick raised are better met using early nutrition plan or specific opened guideway.
Summary of the invention
