Background technology
In China, aviculture is with a long history, and in recent years, development is particularly rapid, and oneself develops into intensive, specialized, modernization industry from sporadicly raising scattered of household sideline production formula, becomes a large pillar of the economy of China rural area and animal husbandry.Chick refers to from going out the chicken of shell to 7 weeks age grade sections, and whether the health of chick is the basis ensureing chicken production performance and ensure poultry economic benefit.And for chick, it has self certain Thermoregulation ability, but still imperfection, the change of temperature is quite responsive to external world, and therefore the administrative skill of brood time most critical is the regulation and administration of temperature.When hatching chick summer, because temperature is higher, chick can not maintain body temperature balance, body heat and the moisture loss of chick are affected, anorexia, a large amount of dehydration, metabolism is obstructed, grow slowly, have a delicate constitution, resistance declines, easy catching a cold or infect respiratory diseases and peck addiction, the death rate raises, therefore, in summer high temperature period, chick broods in management process still based on temperature control, and also easily grow various pathogenic microorganisms in drinking water during summer temperature height, often affect chick healthy, even cause morbidity dead, huge economic loss is brought to poultry production.In addition, for chick, its physiological property has very big difference with becoming chicken, the young bird just having gone out shell due to various physiological function unsound, Thermoregulation ability is low, has a low resistance, digestive function is weak, stomach and intestine volume is little, and feed intake is limited, and muscular stomach grainding capacity is weak, digestive ferment secretion is insufficient, poor to the digestion power of nutriment, the adaptive capacity of environment is poor to external world, and sensitiveness is strong, premunition is poor, easily by various pathogenic microorganism is encroached on, the death rate is high, and these physilogical characteristics determine the importance carrying out feeding and management and epidemic preventing working at brood time.For summer chick height morbidity situation, conventional raise in mainly with antibiotic, chemical synthetic drug, vitamin, trace element and hormone and vaccine as control prece, this scheme not only increases feeding cost, and a large amount of antibiotic that uses has become on record stressor and has damaged immunologic function, reduce systemic immune response, increase the weight of liver kidney burden, also adverse effect is had to Tiny ecosystem flora, and other illness that new bacterial strain brings out can be produced cause great economic loss to poultry husbandry, do not meet the principle of sustainable development.
For Problems existing in existing chick breeding, also certain research is there is in prior art, such as application for a patent for invention 201210301777.2 discloses a kind of chick Chinese medicine bag for preventing infectious disease feed addictive, by realgar 5 ~ 15 parts, the Chinese bulbul 5 ~ 15 parts, purslane 8 ~ 15 parts, golden cypress 5 ~ 15 parts, manyleaf meadowure rhizome and root 10 ~ 15 parts, Ke Zi 10 ~ 15 parts, sweet wormwood 5 ~ 15 parts, the Radix Astragali 3 ~ 6 parts, Radix Codonopsis 4 ~ 8 parts, the root of Dahurain angelica 2 ~ 6 parts, rattletop 10 ~ 15 parts, radix bupleuri 6 ~ 10 parts, rice sprout 12 ~ 15 parts, mountain plants 7 ~ 12 parts, god is by 20 ~ 50 parts, 5 ~ 9 parts, Fructus Hordei Germinatus is made, make the survival rate of chick compare 82% of control group and bring up to 95%.But above additive mainly pays close attention to the control of disease, and do not notice the nutritional need of chick, even if used in combination with conventional chicken feed, its effect also has some limitations.Thus, for the demand of existing chick breeding, continual exploitation one can improve chick nutrient absorption and resistance against diseases, particularly high temperature resistance stress feed addictive.

Survival assays:
The product that chicken house uses the embodiment of the present invention 1 is cultivated scale chick; corn protein powder is adopted to substitute feed addictive of the present invention as a control group; two groups are respectively 1000 chick hatching out summer; cultivate after 1 month; use the survival rate of feed addictive group of the present invention to be 96.5%, and the survival rate of control group is only 79.6%.
From above result of the test, due to formula composition and the proportioning of uniqueness of the present invention, the product of the relatively existing anti-stress feed addictive class of the present invention is made to achieve unforeseeable technique effect, from weight gain rate, use the test group of product of the present invention, its weight gain rate is in high temperature environments apparently higher than blank group and prior art control group, namely the chicken of test group now at high temperature can better grow, and the body dehydration and the Body weight loss caused of being off one's feed that high temperature causes can be reduced, on the other hand, from the physiochemical indice of chick, wherein CK enzyme, ALD and INS is the main monitoring index of instruction chick under stressed condition, use every biochemical indicator of the chick of feed addictive of the present invention close with normal chick, and Comparatively speaking there is very large fluctuation in control group, and every blood parameters of prior art control group is also higher than test group of the present invention, as can be seen here, feed addictive of the present invention fundamentally improves the Heat-temperature stress ability of chick, the raising of this ability is that those skilled in the art are difficult to by simply improvement and routine test obtain on the basis of existing technology, it is that the one-tenth of uniqueness of the present invention is grouped into and the unforeseeable technique effect acquired by proportioning.
As can be seen here, feed addictive of the present invention significantly can improve the Heat-temperature stress ability of chick, and chick still can be grown faster at high temperature, and its applicable south China area uses, especially the time-division in summer, it has great importance for the heat acclimation ability improving chick.In product of the present invention among a small circle process of the test, raiser generally reflects that product of the present invention can reduce chick infects class disease generation in summer, and chick growth is fast, and survival rate is high, well improves the culture benefit of raiser.
