×108Cfu/mL, control group 3 and the difference of embodiment 3 are not adding schizochytrium limacinum in madder color preparation process.
Contrast test is carried out to control group 1-3 and embodiment 3 by the method for test example 1, its result is shown by identical feeding
Support and condition of storage, pig feed of the pig feed compared with fed control group 1-3 by feeding embodiment 3 can more improve pig weightening and
Feeding, and the pig feed of embodiment 3 is lower compared with the peroxide value, acid value and total number of molds of control group 1-3 pig feed.Effect
Fruit trend is：The ＞ of 3 ＞ control groups of embodiment, 2 ＞ control groups 1 controls 3.Wherein, the effect of control group 2 is less than the original of embodiment 3
Because may is that the number of viable in control group 2 contained by schizochytrium limacinum bacteria suspension is excessive, cause bacterium dense excessive in enzymolysis liquid, respectively
Mutually suppress growth between bacterium, reduce the antioxidant effect of madder color on the contrary.
Thus illustrate whether to add schizochytrium limacinum in madder color preparation process to improving the growth performance of pig and preventing
Feed fat is aoxidized and gone mouldy with material impact.
Test example 5
By taking embodiment 3 as an example, four major class control groups, the difference of the first major class control group and embodiment 3 is that feed adds
Agent is only containing any one in Salvia japonica, Huai Goat, resveratrol, madder color and acidulant, the second major class control group
Difference with embodiment 3 is that feed addictive only contains Salvia japonica, Huai Goat, resveratrol, madder color and acidulant
In any two kinds, the difference of the third-largest class control group and embodiment 3 is that feed addictive only extracts containing Salvia japonica, the sophora bud
Any three kinds in thing, resveratrol, madder color and acidulant, the fourth-largest class control group and the difference of embodiment 3 are to raise
Feed additives are only containing any four in Salvia japonica, Huai Goat, resveratrol, madder color and acidulant.
Contrast test is carried out to first to fourth major class control group and embodiment 3 by the method for test example 1, its result shows
Show by identical raising and condition of storage, the pig feed by feeding embodiment 3 feeds the pig feed of four major class control groups more respectively
The weightening and feeding of pig can be more improved, and the pig feed of embodiment 3 is compared with peroxide value, the acid value of the pig feed of four major class control groups
It is lower with total number of molds.Effect trend is：The third-largest major classes of class control group ＞ second of the fourth-largest class control group ＞ of the ＞ of embodiment 3
Control group ＞ the first major class control groups.Also, effect possessed by embodiment 3 be more than the fourth-largest class control group in any one group with
In first major class control group in any one group of combination, the third-largest class control group any one group with it is any one in the second major class control group
Group combination.
Thus illustrate whether pig feed contains Salvia japonica, Huai Goat, resveratrol, madder color and acidulant simultaneously
To improving the growth performance of pig and preventing feed fat from aoxidizing and going mouldy to be respectively provided with material impact.
