The prescription of control group daily ration has adopted the sodium butyrate that on the basis of embodiment of the invention prescription, has reduced 0.05% acidulant, 5% whey powder, 0.1% six and little ecology and 0.04%, and the part of minimizing substitutes with the corn of equivalent.
Five, testing index and method
1, growth indexes
In 8 empty stomaches of test the 1st day and the 29th day morning the examination pig being weighed, is each stage body weight of unit record and feed consumption rate with the hurdle to calculate average daily gain, average daily ingestion amount and expect anharmonic ratio.
Average daily gain (ADG)=(end weight-initial weight)/fate
Average daily ingestion amount (ADFI)=feed consumption rate/fate
Material anharmonic ratio=feed consumption rate/weightening finish
2, grice diarrhoea rate
Write down a number of having loose bowels of test pig every day for unit with the hurdle, in order to calculate diarrhea rate.Adopt 5 grades of marking systems, 1 minute=hard excrement; 2 minutes=normal ight soil; 3 minutes=soft, partially-formed ight soil; 4 minutes=half is aqueous, starchiness ight soil; 5 minutes=watery stools.With ight soil must be divided into 4 fens, 5 fens persons confirm as diarrhoea.
Diarrhea rate is represented by the percentage of grice diarrhoea head number/total number.
3, excrement appearance index detects:
Get fresh excrement appearance detection the 30th day morning in test, calculate coliform count, Bacillus acidi lactici number, total bacteria count, Escherichia coli/total bacteria count, Bacillus acidi lactici number/total bacteria count, Bacillus acidi lactici/coliform count.
Six, data
Utilize SPSS12.O software that the result of this experiment gained is carried out variance analysis and multiple ratio.Result of the test is represented with mean value scholar standard deviation.
Seven, result and analysis
The different daily rations of table 1 are to the influence of weanling pig production performance and diarrhea rate
Annotate: all represent difference not remarkable (p>0.05) with the no mark person of line data shoulder.
The different daily rations of table 2 are to the influence of the young diarrhea rate that weans
The different daily rations of table 3 are to the influence of weanling pig excrement appearance index
We can learn through above-mentioned data:
1, with control group relatively, test group daily ration of the present invention can improve the daily gain (p < 0.05) of weanling pig significantly, reduces feedstuff-meat ratio (p < 0.05), improves the palatability of feed simultaneously, improves feed intake (p>0.05).And with the piglet that the piglet ratio that the embodiment of the invention is fed is fed with conventional feed for weaned, weightening finish improves 8.5%, and feedstuff-meat ratio reduces by 4.57%, and diarrhea rate has reduced by 50%.
2, analyze from excrement appearance testing result; Lactic acid bacteria/total bacteria count and lactic acid bacteria volt enterobacteria number also have corresponding to performance test group Escherichia coli quantity all to be less than the basal diet group with each processing daily gain feed intake and diarrhoea situation, and lactic acid bacteria/coliform count all is higher than the basal diet group.
The weanling pig average weight that the baby pig feedstuff of embodiment of the invention test group is fed, survival rate, diarrhea rate etc. all be superior to the feed for weaned of control group, and the mixed feed that proves embodiment of the invention prescription is the nutritional need that can finely be applicable to weanling pig.
The above is merely preferred embodiment of the present invention, and is in order to restriction the present invention, not all within spirit of the present invention and principle, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
