Comparative test, specific experiment scheme are as follows:
The beef cattle that 32 weight are consistent as far as possible, are in a good state of health is selected to be randomly divided into control group by weight phase approximately principle
With test group one, test group two, test group three, every group of 8 oxen, big column is raised, and original body mass difference is not significant between each group.From
By drinking water, metering feeding, formal test 30 days, initially ox body was weighed at the end of for test, and test site is Hubei Province beef cattle
Feed lot.
Wherein, the feed that test group one, test group two, test group three are fed is respectively embodiment one, embodiment two, implements
Feed prepared by example three, and experimental group is the needle mushroom mushroom bran material of purchase, using quantitative feeding, multiple feeding is fed every time
Feed is the 0.5% of beef cattle weight.Test result is as follows:
One, 4 points of every afternoon checks the defecation of every beef cattle, and every group of eight beef cattles are checked, every group
It checks 240 times altogether, appearance is bottle green, distinguishes result such as following table.
Group/index | First moisture (mean value) | External appearance characteristic shapes, without particle number | External appearance characteristic is shapeless, has particle number |
Test group one | 73.5% | 205 | 35 |
Test group two | 74.8% | 221 | 19 |
Test group three | 76.5% | 228 | 12 |
Control group | 80.6% | 163 | 77 |
Interpretation of result: compare between test group and control group, it is known that, eat embodiment one, embodiment two and embodiment three
The defecation situation of the beef cattle of the feed of preparation is preferable, and the beef cattle excrement sample moisture content of control group is high, inclined compared with normal cow dung sample
Dilute, excrement does not form, and has particle, also illustrates that feed digestion utilization power is poor.
Two, after 30 days, the increased average value record of four groups of beef cattle weights is as follows:
Interpretation of result: the weight gain of beef cattle after 30 days, test group obviously increase weight much than control group, therefore it can be concluded that test
Group obtains more the nutrient absorption of feed, more preferably.
Although the embodiments of the present invention have been disclosed as above, but its is not only in the description and the implementation listed
With it can be fully applied to various fields suitable for the present invention, for those skilled in the art, can be easily
Realize other modification, therefore without departing from the general concept defined in the claims and the equivalent scope, the present invention is simultaneously unlimited
In specific details and embodiment shown and described herein.
