The semi open model pig house, online flat foster, dry powder feed, free choice feeding and drinking-water; Conventional program immunity sterilization.The interior all mean temperatures of experimental period house are respectively 28.6 ℃, 29.3 ℃, 29.0 ℃, 27.2 ℃.
1.5 testing index and method
1.5.1 feed intake (kg/ head day): with the repeating groups is unit, the inventory that accurate recording is each, the stage finishes same day, Bu Wu was after jin once fed intake, and adopted clear bag, clear channel process metering residual feed weight, determine each repeating groups food consumption, thereby calculate its feed intake.
1.5.2 daily gain (g/ head day): second day morning of morning same day on-test, end, be unit, weigh on an empty stomach,, and then calculate daily gain by gained initial weight, last re-computation total augment weight with the repeating groups.
1.5.3 feedstuff-meat ratio:, calculate and respectively repeat thin feedstuff-meat ratio by feed intake, daily gain.
1.5.4 death rate (%): experimental period is interior to be unit with the repeating groups, and it extremely washes in a pan pig number of elements accurate recording, calculates each processed group death rate then.
2 results and analysis
Table 3 pair market pig (before the 30kg) production performance and diarrhea rate influence *
* same column is takeed on marking-up mother different table differential different significantly (P<0.05), and same column shoulder marking-up parent phase is with representing difference not remarkable (P>0.05).
By table 3 as seen, compare with interpolation common Chinese processed group, the anti-diarrhea agents processed group of adding 800ppm can significantly improve piglet feed intake, daily gain, feed efficiency (P<0.05), and each index of the anti-diarrhea agents processed group of interpolation 300ppm is suitable with the common Chinese preparation that adds 1500ppm; Feed intake, the daily gain of adding the anti-diarrhea agents processed group of 800ppm all increase than the antibiotic group, and diarrhea rate reduces, and feedstuff-meat ratio improves; Each index of anti-diarrhea agents processed group of adding 500ppm is suitable with the antibiotic group.Illustrate that livestock and poultry anti diar rhea feed addictive of the present invention can effectively improve the growth in piglets performance and reduce its diarrhea rate, the 500ppm anti-diarrhea agents can effectively substitute antibiotic.

Table 5 pair meat chick production performance and diarrhea rate influence *
* between same column, shoulder marking-up parent phase is represented difference not remarkable (P>0.05) with the person, and alphabetical different persons represent difference not remarkable (P<0.05).
Result of the test shows, add the 800ppm anti-diarrhea agents in the daily ration and can significantly improve meat chick daily gain (P<0.05) than common Chinese preparation group and antibiotic group, the feedstuff-meat ratio of the anti-diarrhea agents group of 500ppm and 800ppm significantly is lower than common Chinese preparation group (P<0.05), and is lower than antibiotic group (P>0.05); The diarrhea rate of the anti-diarrhea agents group of 500ppm and 800ppm and death rate obviously are better than other each groups (P<0.05).This illustrates that livestock and poultry anti diar rhea feed addictive of the present invention can improve the production performance of meat chick, and reduces its diarrhea rate, death rate, and effect is better than common Chinese preparation group, when addition 〉=500ppm, can replace antibiotic fully.
Test example 3
This test example is by embodiment 4 prepared livestock and poultry anti diar rhea feed addictives the effect assessment of weanling pig treatment diarrhoea to be tested.
1 material and method
1.1 experimental animal
120 of the weanling pigs of clinical definite trouble diarrhoea, body weight 8~15kg is divided into 2 groups at random, 60 every group.
1.2 test drug
Antibiotic: 10% Florfenicol+50% Doxycycline
Livestock and poultry anti-diarrhea agents: press the prepared livestock and poultry anti diar rhea feed addictive of embodiment 4
1.3 medication
The spice administration is admixed 10% Florfenicol 1000g/ ton+50% Doxycycline 600g/ ton and is made as the contrast daily ration in the basal diet, admix 3000g/ ton livestock and poultry anti-diarrhea agents and constitute the test daily ration in basal diet, feeds continuously 7 days.
1.4 observation index
Treatment situation: the pig's head number that stopped to suffer from diarrhoea in 3,5,7 days behind the recording medicine.
Cure rate: duration of test, the state of mind, appetite are recovered normal, are not had diarrhoea and dewatering symptom after the pig medication, and do not have the recidivist after 7 days, are judged to healing, calculate cure rate in view of the above, cure rate=healing number/total number.
