Test example 1
1 test period and place
This is tested on December 21,22 days to 2013 November in 2013 and carries out on Beijing Heng Zeyuan animal husbandry Co., Ltd pig farm.
2 materials and methods
2.1 test material
The plant feed additive formula sample of three prevention diarrhea of pigs is provided by Beijing Keepyoung Technology Co., Ltd..
2.2 experimental animals and grouping
Experimental animal selects source identical, 24 about ages in days, 320 of the binary weanling pigs of growing up that are in a good state of health.Male and female separately, raise, and is divided at random 4 processed group by a point circle, and every group of 4 repetitions eachly repeat approximately 20.
2.3 test daily ration and experimental design
2.3.1 test daily ration
Test daily ration is corn one bean pulp type daily ration, is provided by pig farm, and experimental stage feeding feed stuff comprises No. 1, child care and child care No. 2.
2.3.2 experimental design
Table 3 experimental design
2.4 feeding and management
Piglet is all raised in same pig house, takes free choice feeding and drinking-water, by special messenger's feeding and management.Every day clear excrement once, be with weekly pig sterilization twice.
The average Weaning Age of test piglet is 24.3 days, weans and forwards nursery house the same day to.
Test data sheet: duration of test, observe and record the situations such as the appetite, spirit, ight soil of test pig every day.
2.5 testing indexs and method
When off-test, weigh as unit repeating, ramming material, and to repeat calculating, add up the average daily gain of each stage examination pig, average daily ingestion amount, feedstuff-meat ratio as unit.
Just starting weight: when on-test, respectively organize the mean value of the average weight of each repetition;
End is heavy: when off-test, respectively organize the mean value of the average weight (eliminate and dead pig is disregarded) of each pig of repeating to survive;
Average daily gain: the mean value of getting all repetitions in each group;
The death rate: the mean value of getting all repetition death rates in each group.
2.6 data processing
Test data adopts the ANOVA program in Excel2010 and SPSS17.0 statistical software to carry out variance analysis.
3 results and analysis
Three Novel pigs of table 4 are the impact on piglet feed intake and feedstuff-meat ratio with plant extract feed additive formula sample
As shown in Table 4, control group daily gain is the 331g/ previous day, and test group 1, test group 2 and test group 3 daily gains are respectively 356g/ previous day, the 348g/ previous day and 359g/ previous day, have improved 7.6%, 5.1% and 8.5%.From the situation of change of feedstuff-meat ratio, the feedstuff-meat ratio control group of test group 1, test group 2 and test group 3 has reduced respectively 9.5%, 8.9% and 8.3%.As can be seen here, compared with antibiotic group, product of the present invention can improve piglet daily gain, and obviously improves food conversion ratio.
Three Novel pigs of table 5 are the impact on grice diarrhoea rate and the death rate with plant extract feed additive formula sample
Three Novel pigs with plant extract feed additive formula sample on grice diarrhoea rate and the death rate to affect result as shown in table 5.The diarrhea rate of test group 1, test group 2 and test group 3 is respectively 2.39%, 1.67% and 3.40%, has reduced by 61.5%, 73.1% and 45.2% respectively compared with control group.Within whole experimental period, the dead pig of control group is 4, and test group 1, test group 2 and test group 3 are distinguished dead 1,2 and 1, its death rate is respectively 1.25%, 2.5% and 1.25%, has significantly reduced by 75%, 50% and 75% compared with the control group pig death rate; As can be seen here, compared with antibiotic group, product of the present invention can significantly reduce the grice diarrhoea rate profit death rate, improves agricultural product economic benefit.
Test example 2
This test example is that the plant feed additive of preparing by embodiment 1, embodiment 5 is tested the effect assessment of prevention market pig diarrhoea.
Select source identical, Du × large × 300 of the long three way cross market pigs of body weight close (20kg left and right), health, be divided at random 3 processed group (being designated as T1, T2, T3), the T1 group pig basal diet of feeding, T2 group pig basal diet+A1 (5kg/t), the T3 group pig basal diet+A5 (5kg/t) that feeds that feeds, every group of 4 repetitions, eachly repeat approximately 25.Each group pig is all raised in same pig house, takes free choice feeding and drinking-water, by special messenger's feeding and management.Every day clear excrement once, be with weekly pig sterilization twice.Duration of test, observes and records the situations such as the appetite, spirit, ight soil of test pig every day.
The impact of table 6 plant feed additive formula sample on weaned piglets and diarrhea rate and the death rate
As shown in Table 6, the daily gain of control group is the 480.07g/ previous day, and T2, T3 group are respectively 536.56g/ previous day, 550.38g/ previous day, have improved 11.8%, 14.6% compared with control group; T2, T3 group feedstuff-meat ratio is respectively 2.05,2.07, has reduced by 8.9%, 8.0% compared with control group; From the variation of diarrhea rate, the diarrhea rate of T2, T3 group has reduced by 47.5%, 45.5% compared with control group respectively; Within whole experimental period, 2 of the dead pigs of control group, test group is without dead pig.As can be seen here, product of the present invention can improve daily gain, obviously reduces feedstuff-meat ratio and diarrhea rate, reduces pig industry loss, improves raiser's economic benefit.
