Two, on the impact of production performance
Table 2 is on the impact of meat chicken production performance
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Table 2 result shows, the processed group applying feed addictive of the present invention, compared with control group, can improve 42 age in days Broiler chicks daily gains 5.31%; Reduce feed intake 2.73%; Improve food conversion ratio 8.93%.
Three, on the impact of broiler chicken immune performance index
Table 3 immune organ relative weight (%) (n=6)
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Table 4 total serum protein, albumin, globulin (n=6)
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Table 5 PBLC conversion ratio (n=6)
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Spleen, thymus gland, the bursa of farbricius are the Main Immune Organs of bird, are the sources of humoral immunity and cellular immunity cell, and their developmental condition can reflect the function status of immunocyte and the immune level of body indirectly.The increase of immune organ weight is the performance of growing, and the raising of index then means that immune system maturation is very fast.
Serum globulins content is the important indicator of the non-specific humoral immune reaction of reflection body.This test shows: interpolation embodiment 1 feed addictive processed group 21 age in days and 42 age in days serum globulins content are significantly higher than control group, improves the nonspecific immune reaction of body after showing to add feed addictive of the present invention.
Lymphocyte transformation test is a kind of method of vitro detection T, bone-marrow-derived lymphocyte function, lymphocyte transformation rate is the important indicator evaluating cellular immune function, LPS can induce propagation and the conversion of bone-marrow-derived lymphocyte, and the mitogen that ConA is inducer T lymphocyte propagation and transforms.
Table 3,4,5 results show, apply feed addictive of the present invention, broiler chicken immune performance can be strengthened, increase immune organ weight, improve humoral immunity of organism and cellular immune level, processed group, compared with control group, can improve thymus gland, spleen, the bursal index of 21 age in days 42 age in days Broiler chicks; Improve 21 ages in days, 42 age in days Broiler chicks total serum proteins and globulin content and ConA and LPS SI.
Four, on the impact of Broiler chicks alimentary canal shape and Microflora
Table 6 is on the impact (n=6) of broiler chicken alimentary canal pH value
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Alimentary canal content pH value reduces, and is conducive to the growth of intestinal beneficial microbes, and suppress harmful bacteria growth, table 6 result shows, applies the processed group of feed addictive of the present invention, can reduce flesh Stomach duodenum, ileum and cecal content pH value.
Table 7 is on the impact (n=6) of broiler chicken Digestive tract length
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Table 8 is on the impact (n=6) of broiler chicken alimentary canal weight
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Digestive organs and alimentary canal are the places that nutrient digestion absorbs, and gastral length and weight can reflect gastral development degree, are directly proportional to digesting and assimilating of nutriment.Table 7,8 results show, apply the processed group of feed addictive of the present invention, significantly can affect jejunum, duodenum, ileum, caecum length, have the trend increasing glandular stomach, flesh Stomach duodenum, ileum, caecum weight.
Table 9 is on the impact (n=6) of 42 Day-old Broiler Chickens jejunum forms
| Process | Villus length, μm | Crypt depth, μm | Fine hair/crypts, μm/μm |
| Control group | 988.96±24.37 | 156.21±5.93 | 6.33±0.43 |
| Processed group | 1022.45±24.76 | 151.92±5.10 | 6.71±0.27 |
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Intestinal villus is the main portions that Animal nutrition material absorbs, shorten gradually with moving after intestinal segment, intestinal mucosa surface significantly expands absorption area by generation fold and intensive fine hair, and the microvillus of the columnar epithelial cell of intestinal villus makes again absorption area increase hundreds of times simultaneously.Therefore, when fine hair shortens, enterocyte number reduces, and also just reduces the abilities of digestive and absorption of nutriment.Crypt depth reflects the production rate of enterocyte.Height of naps and Crypt depth reflect the absorption function state of small intestine, with the resorption of the ratio of villus length/Crypt depth then concentrated expression small intestine.Table 9 result shows, processed group, compared with control group, after adding feed addictive of the present invention, improves the villus length of jejunum, reduces Crypt depth.
Table 10 is on the impact (n=6) of 42 Day-old Broiler Chickens jejunum Microfloras
| Bacillus acidi lactici log10cuf/g (fresh sample) | Escherichia coli log10cuf/g (fresh sample) | |
| Control group | 6.46±0.39 b | 4.80±0.41 |
| Processed group | 7.53±0.33 a | 4.07±0.13 |
Note: in table, same row shoulder indicates different alphabetical person and represents significant difference (P<0.05).
Escherichia coli, Bacillus acidi lactici are the normal flora of animal intestinal, and Bacillus acidi lactici is the important beneficial bacterium of enteron aisle, ensures animal health with other flora, and regulating the ecological balance in animal body, is indispensable bacterium.Some bacterial strain colibacillary is pathogenic pathogen, often causes Broiler chicks diarrhea and various inflammation, causes serious economic loss.Table 10 result shows, compared with control group, the processed group of adding feed addictive of the present invention does not add the quantity that improve Bacillus acidi lactici in broiler chicken Jejunal chyme, reduces colibacillary quantity.
five, conclusion
Disease-resistant feed additive formula provided by the invention, complex acid agent uses simultaneously, compared with interpolation antibiotic group, meat chicken production performance and immune performance can be improved, improve broiler chicken alimentary canal shape, improve alimentary canal profitable strain quantity and reduce harmful bacteria quantity, substitute antibiotics Be very effective in broiler production.
