Description
Technical field
The invention belongs to pig feed field, be specifically related to a kind of without medicine growing and fattening pig feed.
Background technology
In recent years, China's aquaculture disease takes place frequently, fodder antibiotics uses in a large number, livestock product safety sex chromosome mosaicism, public health potential problem, environmental hazard problem, has become the Main Bottleneck affecting China's livestock and poultry breeding industry and develop in a healthy way.Because Variation Pathogenic Bacteria is many, immunity of livestock low (many antibiotic Immunosuppression power) and environmental stress etc. infect numerous disease because usually causing livestock and poultry and are difficult to cure, many breeding enterprises and raiser are inflicted heavy losses on repeatedly.
And abuse for a long time and the medicines such as Use out of range feeding antibiotic, animals and humans health is produced serious influence.First, destroy animal intestinal micro-ecology balance, directly affect animal health, reduce its premunition; Secondly, easily produce super drug-fast bacteria, make a lot of disease restive and cure, threaten animals and humans healthy, the superbacteria of report has caused Japanese more than 10 event of death has beaten alarm bell again for the mankind because curing recently; Moreover the antibiotic residual security that can reduce animal products, directly affects the foreign exchange earning of China's animal products, remote-effects human health.
In order to animal production safety, reduce in animal feed or prohibit the use medicine to become international community's common action.European Union just forbade using Multiple Classes of Antibiotics additive in livestock and poultry cultivation as far back as in December, 1998, and in animal feeding-stuff, forbade antibiotic in January, 2006 comprehensively.As the China of most development Chinese Home, the Chinese government payes attention to animal production safety in recent years especially, the use of continuous specification feeding antibiotic, reduces or forbid that adding antibiotic also will become inexorable trend in feed.In order to reduce in feed or forbid adding antibiotic, except improving aquaculture management, epidemic prevention level, feed nutrition, adopting safety, efficient, environment protection biological feed addictive, as probio, enzyme preparation etc. coordinate the use of low-protein diet, is main technical solution.
Probio also claims probiotic, probiotics, ecological regulator etc.Probio, as class active bacteria formulation safely and effectively, by promoting the colony balance in animal intestinal, playing growth promotion and improving prebiotic effect (Roberto et al., 2001 such as premunition; Ouwehand et al., 2002; Alexopoulos et al., 2004b).World's Main Developed Countries uses probio in aquaculture comprehensively, and the bacterial classification of Commercialization application mainly contains lactobacillus acidophilus, streptococcus fecalis genus, hay bacillus, saccharomycete and aspergillus oryzae etc.China, through the effort of nearly 20 years, makes great progress,
The Ministry of Agriculture of China announces and allows feeding probio to have bacillus licheniformis, bacillus subtilis, lactobacillus lactis, clostridium butyricum etc. more than 20 to plant.Existing research shows that feeding probio has following action effect:
1. improve production performance, improve efficiency of feed utilization.Current bacillus preparation is widely used in livestock and poultry cultivation, and has the effect improving production performance.To the swine rations of fattening stage, 0.64 × 10 is added respectively in wean
6, 1.28 × 10
6, 1.92 × 10
6the bacillus subtilis of CFU/g and the composite bacteria agent capable (1:1) of bacillus licheniformis can significantly improve daily gain and the feed conversion rate (P < 0.05) (Alexopoulos et al., 2004b) of pig.
2. strengthen immunity of livestock.Probiotics can supplement in enteron aisle the microflora reducing or lack on value volume and range of product, and adjustment or the microbial balance maintained in enteron aisle, strengthen the immunologic function of body, promotes the absorption and digestion of nutriment, thus reach the object of preventing and curing diseases.333 piglets that Li Fangyi (2002) selects 24 sows to produce are tested, to 244 piglets that diarrhoea and diarrhea occur, feed with the beneficial bacterium be made up of Bacillus acidi lactici, streptococcus fecalis and bacillus more, cure 234, cure rate reaches 95.9%, Be very effective.
In addition, also have some compositions in feed owing to lacking corresponding enzyme in animal pig body, cannot digestibility and utilization, serve as the bowel problems such as trophism diarrhea, indigestion to body band.Solve problems except using medicine to control, except diarrhoea, enzyme preparation to be used in feed.This kind of exogenous enzyme preparations: the use of zytase, mannonase cellulase etc. supplements kind and the vigor of the digested enzyme of animal alimentary canal, based on the various anti-nutrient substances of the SNSP compositions such as xylan, mannosan, cellulose in degraded feed, destroy cell wall structure, promote release and the utilization of intracellular nutritional material, thus improve animal to the utilization rate of feed nutrition material.
Except the trophism diarrhea that indigestion causes, too much albumen is taken in, understand some enter rear intestinal using indigested crude protein and carbohydrate etc. can as the substrate (VanKol, 2000) of the fermentation of microorganism and propagation.Low-protein diet refers to and Different Dietary Protein Levels is reduced 2%-4% by NRC proposed standard.Animal use be amino acid, the basis of daily ration amino acid balance reduces forage protein can not affect growth of animal.Therefore low-protein diet supplements synthesizing amino acid, will reduce non-digestible protein and enters the amount of rear intestinal, and reduce the propagation of harmful bacteria in chitling road and the generation of associated toxin, and reduce the generation of intestines problem.
