Contrast test
First, the contrast test such as feed nutrient and physical behavior
By the broiler fodder of embodiment 3（Embodiment group A）, embodiment 4 carp feed（Embodiment group B）And it is not added with this hair
The broiler fodder of bright food dusty yeast（Control group A）And carp feed（Control group B）Nutrient component determining is carried out, measurement result is such as
Shown in table 1, and physical behavior measure is carried out to the feed of four experimental groups respectively, as a result as shown in table 2.
Each experimental group feed nutrient table of comparisons of table 1
| Project | Embodiment group A | Control group A | Embodiment group B | Control group B |
| Crude protein % | 22.02 | 21.99 | 34.12 | 34.28 |
| Fatty % | 3.05 | 3.01 | 10.05 | 10.09 |

| Calcium % | 0.94 | 0.93 | 0.91 | 0.92 |
| Phosphorus % | 0.64 | 0.64 | 1.35 | 1.34 |
| Calcium-phosphorus ratio | 1.47 | 1.45 | 0.67 | 0.69 |
By above-mentioned data, it can be seen that the feed of the embodiment of the present invention 3 and embodiment 4 containing food dusty yeast, nutritional ingredient is such as
Crude protein, fat and calcium etc. and traditional broiler fodder and carp feed are basically identical, therefore, the embodiment of the present invention 3 and embodiment 4
Feed can be good at meeting the nutritional needs of the animals such as broiler chicken, carp.
Each experimental group feed physical behavior table of comparisons of table 2
| Project | Embodiment group A | Control group A | Embodiment group B | Control group B |
| Feed hardness kg | 5.05 | 3.22 | 4.05 | 2.62 |
| Pulverization rate % | 1.2 | 2.6 | 0.44 | 1.60 |
| The % of rate containing powder | - | - | 0.32 | 1.52 |
| Water resistance % | - | - | 27.85 | 19.65 |
By above-mentioned data, it can be seen that compared with traditional broiler fodder, broiler chicken of the embodiment of the present invention 3 containing food dusty yeast is raised
Material hardness is improved, and pulverization rate is significantly reduced；Carp feed of the embodiment of the present invention 4 containing food dusty yeast is hard in feed
Traditional carp feed is significantly better than that in terms of degree, pulverization rate, rate containing powder and water resistance.
2nd, the table of comparisons that feed influences on breeding performonce fo animals
（1）Experimental animal is only used as from the commercial broiler 2400 of 1 age in days Ross 308,2 test groups are randomly divided into, each group 4
Repeat, it is each to repeat 300.The broiler fodder of embodiment 3 is respectively adopted in 2 test groups（Embodiment group A）Raised with traditional broiler chicken
Material（Control group A）Fed, fed to 38 age in days off-tests.
Feeding management program is pressed during experiment《Feeding of broiler administrative manual》Carry out, hand fed（Limit is raised, free water）,
And excrement and tank are cleared up daily.Observation chicken group situation, records survival rate daily.Whole column experimental chicken is carried out in the age in days of broiler chicken 38
Weigh on an empty stomach and count feed intake, calculate average daily gain, average daily gain, feed-weight ratio, experimental data is as shown in table 3.
Wherein, traditional broiler fodder that control group is used for embodiment 3 in be not added with the feed of food dusty yeast.
Each test group growth of meat chicken index table of comparisons of table 3
| Project | Embodiment group A | Control group A |
| 38 ages in days end weight（g） | 2302 | 2189 |
| Feed-weight ratio | 1.515 | 1.536 |
From the data of table 3：The chick fed using the broiler fodder containing food dusty yeast of the embodiment of the present invention 3, extremely
38 ages in days end weight is apparently higher than the chick fed using traditional broiler fodder, and feed-weight ratio is substantially less than using traditional broiler fodder
The chick of nursing.
（2）From the tail of healthy carp 360 that size, weight are basically identical, 2 groups, every group of 180 tails, every group of setting 6 are randomly divided into
Repeat.The carp feed of the embodiment of the present invention 4 is respectively adopted in 2 test groups（Embodiment group B）With traditional carp feed（Control group
B）, feed experiment in 56 days and terminate.
Routinely manage temporarily to support before experiment and tamed for 2 weeks, during domestication, each test group feeds conventional feed；Daily
Artificial be satiated with food feeds four times（8:00、11:00、14:00、17:00）, 10 feeds of input, treat that fry robs food and finished every time, continue
Input 10, is circulated successively, and observation fry ingests situation, when part fish dissociates Feeding Area, feeding volume is suitably reduced, until 2/3
Test fish is left, you can stopping is fed, and feeding volume is adjusted at any time according to water temperature and water quality situation during raising.Carry out daily carp
Rate of body weight gain, specific growth rate, feed coefficient, the influence of survival rate and coefficient of condition, result of the test are as shown in table 4.
Wherein, traditional carp feed that control group is used is made up of the raw material of following percentage by weight：Dregs of beans 26%, flour
9%th, wheat bran 8%, rapeseed cake 19%, maize germ cake 12%, DDGS 16%, fish meal 5.5%, soya-bean oil 3%, calcium dihydrogen phosphate 1%, stone flour
0.29%th, DL- METHIONINE 0.04%, Choline Chloride 0.15%, Pulvis Fellis Suis 0.02%.
Each test group carp growth index table of comparisons of table 4
| Project | Embodiment group B | Control group B | P values |
| Initial counterpoise（g） | 16.00±0.04 | 15.98±0.03 | 0.082 |
| Whole end counterpoise（g） | 83.92±2.61a | 77.94±1.86b | 0.007 |
| Survival rate（%） | 100.00±0.00 | 99.17±2.04 | 0.391 |
| Specific growth rate（%/d） | 3.02±0.16a | 2.83±0.04b | 0.009 |

| Protein efficiency ratio, PER % | 2.77±0.19a | 2.43±0.08b | 0.006 |
From the data of table 4：Compared with traditional carp material, raised using carp of the embodiment of the present invention 4 containing food dusty yeast
Expect the carp fed, survival rate is higher by control group apparently higher than control group, eventually end counterpoise, specific growth rate and protein efficiency ratio, PER
5.98g, 0.19 %/d and 0.34 %, feed coefficient are substantially less than control group 0.16.
In summary, the food dusty yeast that Example 1 and Example 2 of the present invention is provided has extraordinary adhesive effect, by it
Applied in terms of feed manufacturing, the original nutritive value of feed can not only be ensured, the normal nutrition demand of animal is met, and
Feed physical behavior can also be obviously improved, the utilization rate of feed is improved.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in the spirit and principles in the present invention
Within, any modification, equivalent substitution and improvements made etc. should be included in the scope of the protection.
