Culture experiment is gone.
Embodiment 5
1st, experimental animal and packet
Test period totally 56 days, control is used as by test feed and conventional feed of the feed prepared by embodiment 1-3
Feed, carries out grass carp nursing, selects disease-free and injury-free vivid body colour, neat specification, body surface, physically fit, build and weight basic
Consistent common grass carp, weight are (150 ± 6.0) g, amount to 360 tails, random packet, if 3 test groups, 3 control groups, divides
For 1 group of 1 group of experiment, 2 groups of experiment, 3 groups of experiment and control, 2 groups of control, 3 groups of control, every group of 3 repetitions, are distributed to 18 cultivation
In bucket, every barrel of 20 tails, carry out culture experiment in glass tempering bucket.
2nd, feeding management
Experiment is cultivated using microcirculation water, clearance-type oxygenation；Water temperature is controlled at 22~25 DEG C；Respectively at daily 9：00、
13：00、17：00 feeds 3, and feeding rate is stepped up to 2.5% with the rise of temperature from 1.5%, is fed, thrown every time
Feed and continue 30-50 minutes, day feeding volume is 1.5%-the 2.5% of quality of fishes.Daily measure water temperature, observes and records
Test fish ingest and activity situation.Feeding volume is adjusted weekly according to fish body weight and situation of ingesting in time.After raising 60 days, take
Sample measures indices.In experimental period from June 30,1 day to 2017 May in 2017, add up to 60 days, sample collection and analysis
It is as follows：
Rate of body weight gain (%)=(terminating counterpoise-initial counterpoise)/initial counterpoise；
Particular growth amount (g/d)=(terminating counterpoise-initial counterpoise)/raising number of days；
Feed coefficient=the gross weight that feeds intake/fish body total augment weight.
Every group results are averaged, and concrete outcome is as shown in table 1.
Table 1 cultivates comparative test result.
Wherein, the formula of control group 1 is：It is 100 parts of wheat, 118 parts of wheat bran, 120 parts of rice bran, 80 parts of rice bran meal, de-
170 parts of the skin expanded soybean dregs of rice, 40 parts of fermented bean dregs, 200 parts of rapeseed dregs, 80 parts of Cottonseed Meal, 20 parts of inlet steam fish meal, soybean phosphorus
10 parts of fatty oil, 10 parts of soya-bean oil, 3 parts of sodium chloride, 16 parts of zeolite powder, 20 parts of calcium dihydrogen phosphate, 3 parts of choline chloride (VB4,60%),
10 parts sweet 0 part of courage health, fish of compound premixed feed.
The formula of control group 2 is 199 with embodiment 1, wherein dregs of beans, and zeolite powder 7, imported fish meal content is 0, powdered rice hulls
For 0, Gan Dankang 0.
The formula of control group 3 is 242 with embodiment 1, wherein dregs of beans, zeolite powder 4, fermented bean dregs 0, and imported fish meal is
0, the content that rice husk powder content is 0, Gan Dankang is 0.
As can be seen from the above Table 1, feeding is used for the feed ratio control group mixed feed rate of body weight gain for improving grass carp survival rate
More 17%；Feed coefficient reduces by 0.227, and survival rate improves 31.63%.
