Description
Technical field
The present invention relates to technique for producing feed fields, and in particular to a kind of free-ranging chicken chicken feed and preparation method thereof.
Background technique
With the improvement of people's living standards, the demand of chicken is constantly soaring, while people are to the quality requirements of chicken
Also it is gradually rising.Free-ranging chicken is because of the features such as chicken is delicious in taste, Egg Quality is excellent, full of nutrition, more compared to cage bird
By the favor of consumer.
Chicken has many advantages, such as that characteristics, the delicious meats such as resistance to crude feed, broodiness are strong and premunition is strong are very popular.
Chicken is different from the broiler chicken of cage, with " hillside free-ranging chicken " be it is best, crest is big and red, and property is strong bellicose, hen cockscomb
It is minimum.Chicken is also named hen, stupid chicken, refer to from ancient times it is domestic tame, from without it is any hybridization and optimization breed, for a long time
To look for food or feed naturally in conjunction with crude feed, there is stronger field to look for food and survival ability.Currently, the cultivation of chicken is main
It is to lie substantially in daytime based on putting in a suitable place to breed and put the time in a suitable place to breed.Although the most of the time, which puts in a suitable place to breed, can preferably keep chicken meat
Quality.But put in a suitable place to breed after for a long time, so that chicken food-intake is few, the speed of growth is slow, influences the economic benefit of chicken cultivation.
Feed is a key factor for influencing chicken growth.Current normal diet, be not for chicken feed and
Production, without specific aim, has that feedstuff-meat ratio is excessively high, the speed of growth is slow, seriously affects economic benefit.Chicken (1-
Raising 50d) is a vital link in poultry husbandry, and chicken constitution is weaker, and biological organs development is not perfect, is easy hair
Sick bacterium infection phenomenons will lead to chicken group's survival rate decline once management raising is unreasonable, and weak chick increases, directly affects
To the culture efficiency in later period, in existing breeding process, free-ranging chicken chicken feed proportion is dealt with improperly, and chicken is caused to be difficult to disappear
Change the nutrition absorbed in feed, growth and development is obstructed, and the survival rate and growth of chicken are influenced.Therefore, free-ranging chicken how is improved
Growth performance improves production efficiency and feed conversion rate, becomes common decentralized household concern the most.
Summary of the invention
Goal of the invention of the invention first is that, in view of the above-mentioned problems, providing a kind of free-ranging chicken chicken feed, trophic structure
Equilibrium, cost is relatively low, has stronger specific aim, according to the distinctive physiological conditions of less than 50 days free-ranging chickens of age in days and its institute
The nutriment needed, the chicken class of age in days section provides preferable mixed feed thus.
In order to achieve the above objectives, the technical scheme adopted by the invention is that:

Grain, obtains chicken feed finished product.
Preferably, in the step S2, fish gill extract specific is put into salt water the preparation method comprises the following steps: take the fresh fish gill
Middle shearing is slurried, and then adds pepsin to 3.5~4.5 with salt acid for adjusting pH value, 40~45 DEG C at a temperature of digest
4~6 hours, it is eventually adding ethyl alcohol, centrifugation stands, takes supernatant layer liquid to get the fish gill extract.
Due to the adoption of the above technical scheme, the invention has the following advantages:
1. chicken feed of the invention, trophic structure is balanced, cost is relatively low, has stronger specific aim, small according to age in days
In the distinctive physiological conditions of free-ranging chicken on the 50th and the nutriment needed for it, the chicken class offer of age in days section is preferably matched thus
Feed is closed, immunity can be promoted, reduce illness rate and promote the healthy growth of chicken.
2. chicken feed of the invention is added with premix, it is rich in amino acid, vitamin, microelement, tea polyphenols and shell
Polysaccharide can be improved immunity of organisms and promote the growth of chicken.Balanced microelement and vitamin are added, zinc, selenium are rich in
Equal elements, promote being absorbed and utilized for zinc, increase organic Zn content in chicken body, enhance the healthcare function of chicken；Increase chicken body
Interior Se content, thus enhance the oxidation resistance of chicken, in immunity of organisms and environment resistant heavy metal contaminants ability, mention
The survival rate of high chicken.Chicken immunity can be improved in vitamin A, vitamin B, vitamin C, vitamin D and vitamin E.Tea
Polyphenol and chitin by raising immunoglobulin total amount and make it maintain high level, stimulate the variation of antibody activity, thus
Improve overall immune ability.
Complex enzyme can degrade simultaneously, and macromolecular is non-to determine powder polysaccharide for oligosaccharides, and intestinal lactobacillus and Bifidobacterium is promoted to increase
It grows, pathogen is prevented to be colonized, promote alimentary canal reparation, maintain intestinal flora balance, keep intestinal health state, promote chicken
Growth.Using zytase, 1,4 beta-glucanase, 'beta '-mannase, cellulase, protease, amylase, lipase and phytic acid
Enzyme synergistic effect, significant effect.
3. chicken feed of the invention, also contains phagostimulant, the special odor that fish gill extract has can promote chicken
Appetite；Broken wall yeast powder not only has the function of food calling, can also improve the immunity of grass carp itself, reduces the hair of disease evil
It is raw；Cream lactone and ethylmaltol are used cooperatively, and are further improved and are enhanced the milk fragrance and sweet fragrance of phagostimulant, make its taste
Road promotes chicken feed, to improve efficiency of feed utilization closer to the preference of chicken.Passion fruit and cortex cinnamomi synergistic effect, not only
The mouthfeel that feed can be improved, have stimulated the appetite of chicken, and enhances strengthening the spleen and stomach, promotees the function of digestion, and then effectively mention
Feed intake of the high chicken to feed and the sorption enhanced to effective component in feed act on.

Equilibrium, cost is relatively low, has stronger specific aim, and the chicken class of age in days section provides preferable mixed feed thus, can promote to exempt from
Epidemic disease power reduces illness rate and promotes the healthy growth of chicken.Meanwhile the variation of feed nutrition structure will have a direct impact on the life of chicken
It is long.
1-2 and comparative example 1, which can be seen that phagostimulant, in conjunction with the embodiments to promote chicken to feed, so that chicken be promoted to grow, mention
High daily gain improves the utilizing status of additive.
1-2 and comparative example 2-4, which can be seen that complex enzyme, in conjunction with the embodiments can promote the digestion, growth and improvement of chicken
Chicken immunity, the effect of single enzyme have its limitation, and the combination of a variety of enzymes can be played the role of mutually promoting, raising
Effect.
1-2 and comparative example 5-6 can be seen that tea polyphenols in conjunction with the embodiments and chitosan can be improved chicken immunity, from
And reduce the death rate.
Above description is the detailed description for the present invention preferably possible embodiments, but embodiment is not limited to this hair
