Description
Technical field
The present invention relates to field of animal feed, particularly a kind of laying hens in brooding period feed.
Background technology
Laying hen refers to raise the chicken of special raw egg with the supply egg.Egg is the major source of revenues of raising laying hen.Different with meat chicken, the major subjects that people raise laying hen is to improve egg quality and maintenance or improve egg production, and is not the raising chicken meat quality.China laying hen industry is through the fast development of decades, becomes the maximum country of birds, beasts and eggs output in continuous 21 years.1980 to 2005, China's birds, beasts and eggs output year increasing velocity was 7.8%.According to FAO (Food and Agriculture Organization of the United Nation) (FAO) statistics, China's birds, beasts and eggs output was 2879.5 ten thousand tons in 2005, accounted for 44.5% of Gross World Product, and wherein egg output is 2,435 ten thousand tons, accounts for 41% of world's egg total output.
Modern laying hen already it is generally acknowledged and 0～8 week was the raising stage of chick, the quality of egg chick breeding effect, and the laying hen economic benefit in stage of laying eggs after being directly connected to is unusual the key link.The operational phase of laying hens in brooding period feed in the market was 0～6 week or 0～3 week; This normal diet is in order to reduce diarrhea rate; A large amount of antibiotic that use cause the body drug resistance to strengthen, and autoimmunity descends; And normal intestinal flora is damaged, cause problems such as the incidence of disease is high, survival rate is low, body weight is not up to standard.And 0～3 the stage in week chick to experience transportation, vaccinate, breaking beak, high temperature low humidity etc. stress be very serious, need high-quality feed to reduce and avoid these problems.Therefore, provide a kind of antibiotic laying hens in brooding period feed that do not contain that is directed against 0～3 all chick designs to have realistic meaning.
Summary of the invention
In view of this, the present invention provides a kind of laying hens in brooding period feed.This feed does not use antibiotic, can promote the chick intestinal health, and strong chick physique improves chicken immunity and reduces the death rate, improves culture benefit.

Embodiment 6
Test is carried out at certain chicken house.The highest, the top-quality chick brood time of price feed was as control group on the market at that time to select test, and the feed group that the embodiment of the invention of feeding 1 to 5 provides is a test group.
Test chicken divides into groups: the single-factor experimental design is adopted in test, and experiment material is selected 6000 blue brown 1 Japanese instar chicklings in sea, is divided into two groups, establishes 3 repetitions for every group, and each repeats 1000 chickens;
The feed group that the control group and the embodiment of the invention 1 to 5 of feeding respectively provides.
Feeding method: the 1-2 age in days is fed on paper, and 3 ages in days begin to feed at the special-purpose hopper of chick for-3 weekends;
Test temperature: adopt the hot-blast stove heating, the hen house temperature was controlled at 32-35 ℃ in preceding 3 days.Later on according to the strict control of the blue brown brooding temperature in sea;
Testing index comprises: 3 all age--body weight, feed intake, the death rate, diarrhea rates.Slaughter experiment: immune organ and digestive organs; The result sees table 1 to table 3.
Table 1 the present invention is to the influence of egg chick production performance
Annotate: the female different table differential of colleague's shoulder marking-up different significantly (P＜0.05).
See from table 1 result of the test, 3 weekend egg chick body weight, the chick test group is higher than common material group group, and significant difference, improves 5.29%, of the present invention group of performance clear superiority.The common material group in survivability of chicks aspect significantly is lower than test group, is lower than 0.24%.The feed intake test group is higher than common material group, explains that feed digestibility of the present invention is high, and chicken is glad to search for food; Feed group chick diarrhea rate of the present invention reduces by 1.92%, and this shows if can let chick search for food improves use feed of the present invention, helps growth fast in early stage, reduces the incidence of disease, the minimizing medication.The long testing result of feed group chick shin of the present invention explains that for exceeding common material group 1.8mm preceding 3 all chick material are influential to the growth of build basis.In sum, feed of the present invention finishes for the chick brood time and the peak phase of laying eggs is brought into play maximum egg laying performance potentiality and had laid a good foundation.
Since 3 ages in week immune organ exponential sum digestive organs grow the laying hens in brooding quality, even the laying hen egg laying performance is had material impact, therefore carry out slaughter experiment 3 weekends and detect These parameters.
Table 2 chick immunity at 3 weekend and organ digestion assessment of indices
Annotate: the female different table differential of colleague's shoulder marking-up different significantly (P＜0.05).
Table 3 the present invention is to laying hen small intestine health affected
Annotate: same column shoulder mark contains same letter person and is difference not significantly (P>0.05), and the female complete different persons of shoulder marking-up are difference apparent (P < 0.05), and each data is average ± standard deviation in the table.
Can find out from table 2; Utilize plant extracts to substitute the antibiotic group; Liver liver index, thymus index and index and spleen index be apparently higher than common material group, explains that certain or a few kinds of nutrients in the feed of the present invention are grown egg chick immune organ to have played important function.Can find out from table 3, the intestinal villi length and the degree of depth, of the present invention group apparently higher than the normal diet group.
We can find out from result of the test; In 3 stages at weekend of egg chick; Test group of the present invention is measured at many indexs such as body weight gain, immune organ growth, digestive organs growth, diarrhea rate and the death rates and all is better than common material group, has proved absolutely the advance of theoretical correctness of product of the present invention and technology.
The above only is a preferred implementation of the present invention; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; Can also make some improvement and retouching, these improvement and retouching also should be regarded as protection scope of the present invention.
