The embodiment of the present invention also provides a kind of preparation method for the feed that improves chicken immunity, comprises the following steps:
The first step, the preparation of described Chinese medicine composition additive;
Second step, feed vector is ground into to 100 orders~200 purpose powder, the Chinese medicine composition powder obtained with the 3rd step mixes, pour in the granulating disc that is placed in heeling condition, open granulating disc and make its rotation, while is evenly sprayed the starch solution of vaporific 20% concentration to the mixture in granulating disc, the weight of described starch solution is 1/5~1/10 of described mixture quality, the rotating speed of granulating disc is 50 rev/mins, preparation time is 15 minutes, the spherical particle feed that to be prepared into diameter be 0.8 millimeter;
The 3rd step, the spherical particle feed that second step is obtained, spread on the mesh-belt drier with the portable stainless steel guipure of multilayer, heat drying 10 minutes, the import air temperature of heating is 150 degree, the outlet air temperature is 80 degree, obtains dry feed granules.
Wherein, the first step comprises: according to ratio of weight and number weighting raw materials material, be ground into powder after mixing; Above-mentioned steps is obtained to powder and add in cold water and to soak 24 hours~36 hours, with slow fire boiling, decocting time is 2 hours~3 hours, and decoction liquor is filtered, and obtains the first filtrate, and the dregs of a decoction are standby, and the quality of the water added is 3~5 times of the powder quality that obtains; The filter residue that above-mentioned steps filter is obtained adds in cold water again, with slow fire boiling 2~4 times, decocts 1 hour~2 hours at every turn, filters and merges filtered fluid, obtains the second filtrate, and the quality of the water added and above-mentioned steps add quality identical of water; The first filtrate and the second filtrate are merged, and reduced pressure concentration, except desolventizing, obtains and gets dry extract, dry cream is put into to spray dryer dry, guarantee that EAT is at 170 ℃~190 ℃, 60 ℃~80 ℃ of leaving air temps, be ground into subsequently 200 orders~400 orders, obtain the Chinese medicine composition powder.
Contrast test
Choose 2400 of the healthy meat chicks of 1 age in days, be divided into immediately three experimental group, every group 800, use respectively the feed (embodiment group 1) of the embodiment of the present invention 3, the conventional feed (control group) that is added with the conventional feed (embodiment group 1) of embodiment 2 Chinese medicine compositions and does not add Chinese medicine composition of the present invention to feed respectively the meat chick, 1 age in days starts feeding, and experiment periods is 21 days, sub-cage rearing, free choice feeding, freely drink water.
The mensuration of growth performance index:
When experiment starts and experiment finish to take respectively cage as the weigh empty stomach weight of experimental chicken of unit, record total feed consumption rate, and the average daily ingestion amount of experiment with computing chicken (ADFI), average daily gain (ADG) and material anharmonic ratio (F/G), and the death rate, result is as shown in Table 1 and Table 2.
The mensuration of Immune Organs Index: during 21 age in days, choosing immediately five chickens from each experimental group is slaughtered, complete excision spleen, thymus gland and the bursa of farbricius, remove surperficial connective tissue, the weigh weight in wet base of thymus gland, spleen and the bursa of farbricius, calculate bursa of farbricius index, index and spleen index and thymus index, be calculated as follows (result is as shown in table 3):
Bursa of farbricius index=(bursa of farbricius weight/body weight) * 100%;
Index and spleen index=(spleen weight/body weight) * 100%;
Thymus index=(thymus gland weight/body weight) * 100%.
Data are processed: data are expressed as " average+standard deviation ", adopt the SPSS17.0 statistical software to carry out one-way analysis of variance.
Results and analysis:
Table 1 is respectively organized the broiler growth performance table of comparisons
From the data of table 1, use the chicken of the forage feed of embodiment group one and embodiment group two, its average daily ingestion amount is higher than the chicken of control group, and its average daily gain exceeds respectively control group 3.75g and 3.17g, and its material anharmonic ratio is significantly lower than control group.
The average daily grazing rate of experimental group is compared with the second control group with the first control group, significantly reduces, and average daily gain is significantly higher than the first control group and the second control group, and the material anharmonic ratio of experimental group and the second control group is significantly lower than the first control group.
The table 2 death condition table of comparisons
