Abstract
The invention provides a pig feed additive for improving immunity and promoting growth, belonging to the field of feed additives. The additive consists of compounded traditional Chinese herbal medicines, plant extracts, vitamins, mineral elements and carriers, wherein the carriers are defatted rice bran and wheat bran. The additive is scientific in compatibility and is capable of effectively improving the immunity of pigs, reducing the morbidity of pigs, and replacing or partially replacing the use of antibiotics and chemical synthesized medicines. In addition, the additive can also promote growth of pigs, can increase the feed conversion rate, is beneficial for saving the feed raw material resources which are in shortage increasingly, and plays a significant role in protecting and improving the ecological environment, promoting the healthy development of feed and animal husbandry, improving the culture benefits and reducing the culture risk.
Description
Technical field
The present invention relates to a kind of pig's feed additive, especially relate to a kind of pig immunity and feed additive for promoting growth of improving, belong to feed additive field.
Background technology
In recent years, along with the develop rapidly of China's pig industry, swine disease is popular to be on the rise.The chemical classes medicines such as antibiotic are still the first-selections for preventing and treating various diseases.This not only causes the appearance of a large amount of drug-fast bacterias, worm strain, and cause residual in pork and products thereof of chemicals, bring very big infringement to public health and food security, more do not meet people's's " high-quality, low medicine are residual, green non-pollution " food consumption trend.The consumption that livestock products will meet people requires just must find a kind of safe production model, is first to be vital link and raise.As can be seen here, find one not only safe and effective but also alternative antibiotic substitute seem particularly important.
Meanwhile, in Swine Production, in order to accelerate the growth of pig, obtain larger economic benefit.Most raisers still take the method for antibiotic and chemical synthesis class medicine, can also make the attenuation of small intestine intestines wall in diseases prevention, have promoted the absorption of nutriment, thereby reach the object that promotes pig growth.But the problem of therefore bringing is also apparent, not only the amount of antibiotic and drug use is increasing, effect worse and worse, antibiotic and medicament residue and problem of environmental pollution become and become increasingly conspicuous, therefore for the problem that promotes pig growth, the substitute of developing as early as possible substitute antibiotics and medicine is crucial.
Raising immunity provided by the invention and somatotrophic pig's feed additive, can effectively alleviate the problems referred to above.By application of the present invention, can reduce the incidence of disease of pig and the growth of promotion pig, play good effect for substitute antibiotics and medicine, there is good application prospect.
Summary of the invention
The object of the present invention is to provide a kind of immunity and somatotrophic pig's feed additive of improving.This additive can effectively improve the immunity of pig, reduces the incidence of disease of pig, can substitute or the use of part substitute antibiotics and chemical synthesis class medicine; In addition, this additive can also be accelerated the growth of pig, improves food conversion ratio; be conducive to save the feedstuff of growing tension, for protecting and improving the ecological environment, promote the sound development of feed and animal husbandry simultaneously; improve culture benefit, reduce cultivation risk significant.

test example:
1, experimental animal and experimental design
It is " DLY " tri-crossbreeding of 28kg left and right that 280 subordinate plant of Chengdu Twins Feed Co., Ltd. average weights are selected in test, be divided at random 6 groups, every group of 4 repetitions, 10 pigs of each repetition (male and female half and half), comprising a blank group and 5 test group.Blank group swine rations does not add any enhancing pig immunity and the somatotrophic additive that in embodiment 1-5, make, the additive that in all the other 5 test group swine rationses, additive embodiment 1-5 makes respectively, live pig free choice feeding and drinking-water, carry out routinely immunity and expelling parasite, in experimental period, observe and record the mental status of swine flu situation and pig every day.90 days experimental periods.In feeding process, each group of pig incidence added up.When feeding experiment finishes, growth performance and immune indexes to pig are analyzed.
Data statistic analysis
Test data adopts SPSS19.0 statistical software to carry out statistical analysis, the results are shown in following table.
Table 1 growth performance index
| Project | Control group | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Embodiment 5 |
| Daily ingestion amount/kg | 1.32±0.06 | 1.60±0.05 | 1.55±0.10 | 1.63±0.07 | 1.46±0.03 | 1.50±0.02 |
| Daily gain/kg | 0.50±0.01 | 0.68±0.05 | 0.65±0.03 | 0.70±0.02 | 0.53±0.08 | 0.61±0.03 |

Daily ingestion amount (ADFI): feeding capacity and the clout amount of the each hurdle of accurate recording test pig, calculate every pig average daily ingestion amount and complete average daily ingestion amount of phase weekly;
Daily gain (ADG): test pig starts weekly and finish morning 7:30 weighs on an empty stomach, calculates average daily gain and the full phase average daily gain weekly of every pig;
Feedstuff-meat ratio: (F/G): calculate according to feed intake and weightening finish.
Table 2 immune indexes and the incidence of disease
| Project | Control group | Embodiment 1 | Embodiment 2 | Embodiment 3 | Embodiment 4 | Embodiment 5 |
| IgA/(g/L) | 0.12±0.03 | 0.21±0.03 | 0.19±0.04 | 0.22±0.01 | 0.15±0.05 | 0.16±0.02 |
| IgG/(g/L) | 6.00±0.67 | 8.55±1.21 | 8.12±0.87 | 8.87±1.13 | 6.73±0.84 | 7.32±1.28 |
| IgM(g/L) | 1.04±0.15 | 1.35±0.20 | 1.32±0.22 | 1.38±0.10 | 1.23±0.20 | 1.26±0.18 |
| The incidence of disease (%) | 12.2% | 2.5% | 3.2% | 2.0% | 8.6% | 7.5% |
Immune indexes is measured: the 7:30 in morning last day that experimental period finishes, IgA, IgG and IgM level are measured in each two of fully choosing.
The incidence of disease: sick pig suddenly heating reaches 42 DEG C even higher, and ight soil is dry and hard, lassitude, anorexia or do not eat, normal accumbency together, is reluctant activity, expiratory dyspnea, cough, eye, nose stream mucus.
Interpretation of result: as can be seen from Table 1, daily ingestion amount, daily gain and the feedstuff-meat ratio that embodiment is 3 groups is all better than other each group, and three growth performance indexs of this of control group are all not as each test group.As can be seen from Table 2, IgA, the IgG in 3 groups of serum of embodiment and IgM level are all higher than other each group, and the incidence of disease is all lower than other each group, and immune indexes level and the incidence of disease of each test group all make moderate progress compared with test group.
Conclusion: result of the test shows, the feed addictive that the present invention makes, compared with basal feed, has significantly improved growth performance and the immune level of pig, has reduced the incidence of disease of pig, and immunity effectively improves.
The raw material of this product is green safety material, and can significantly reduce the incidence of disease of pig, strengthen immunity and the growth performance of pig, can be used as antibiotic substitute adds in pig feed, produce the mixed feed that disease resisting effect is good, promote pig fast growth, there are good using value and wide market prospects.
