Embodiment 3 probioticses of the present invention are to the influence of flora in crucian digestive enzyme activity and the enteron aisle
180 tail fingerlings are divided into 3 groups at random; Every group of 3 repetitions; The 3 kinds of feeds of throwing something and feeding respectively: basal diet (I group); In basal diet (moity and trophic level are as shown in table 1), add mass percent and be the compound microecological granular preparation (II group) among 0.02% the embodiment 2, in basal diet, add mass percent and be 0.02% compound microecological liquid state (III group).Test Shui nationality casing is long-pending to be 0.85m * 0.45m * 0.55m, and every case is thrown 20 tail fishes.
The composition and the trophic level of table 1 crucian basal diet
Annotate: additive contains trace element and VITAMINs etc.
The preparation of test group feed: with above-mentioned each raw material pulverizing, thorough mixing behind mistake 60 mesh sieves, the compound micro-ecological preparation granule is fine ground with grinding alms bowl among the embodiment 2; Mix with monocalcium phosphate earlier; Doping again, rod soil, zeolite powder etc. add suitable quantity of water at last, use small meat mincer to process the wet granular material of diameter about as 2.5mm; And the making method of liquid compound micro-ecological preparation group is to replace water with the liquid compound microecological; Add, also process the wet granular material of diameter 2.5mm size then, three kinds of feeds are all at 40 ℃ of oven dry 12h (quality moisture is about 10% to the feed) down then.
Feeding method: crucian domestication was weighed after 15 days, by 2% one 4% of the fish body weight test daily ration of throwing something and feeding, throw something and feed every day 3 times (8: 30,13: 30,18: 30), the unnecessary material of sucking-off is thrown the amount of raising according to the situation adjustment of feeding, and it is satiated with food and does not have the feed residue.Between feeding period, 24.4 ± 3 ℃ of water temperature average out to.Sooner or later each soil pick-up once adopts the flowing water system.Raise 75d post analysis digestive enzyme activity, intestinal microflora etc.Adopt the forint phenol reagent process to measure protease activity, starch enzyme reagent kit is measured amylase activity, and the result sees table 2.
Table 2 compound micro-ecological preparation is to the influence of crucian digestive ferment
Can know by table 2 result; Compare with the I group, protein, diastatic activity in the enteron aisle chyme of II group have improved 24.3% and 58.56% respectively, significant difference (p<0.05); Proteolytic enzyme and amylase activity difference not significantly (p>0.05) in the liver, but the latter has improved 16.20%; Compare with the I group, the protein amylase activity in the enteron aisle chyme of III group also is greatly improved, and this shows, adds the secretion that compound micro-ecological preparation of the present invention can improve the digestive ferment of crucian in the fish meal, thereby improves the utilization ratio of feed.
Through the analysis to the flora in three groups of enteron aisle chymes, it is as shown in table 3 to obtain a result.Analytical procedure to flora is the method that the scientific research personnel knew.
Table 3 compound micro-ecological preparation is to the influence of crucian intestinal microflora
Visible by table 3 result, to compare with the I group, the genus bacillus in the enteron aisle chyme of II and III group, the quantity of milk-acid bacteria have improved 9.6%, 6.9% and 23.6%, 19.6% respectively; Intestinal bacteria then reduce 9.45% and 9.67%, this shows, add compound micro-ecological preparation of the present invention in the feed; Can promote microbial population of animal intestinal tract to increase, produce the voltaile fatty acid that some can suppress harmful bacterium, thereby promote the growth of milk-acid bacteria; Thereby make the probiotics in the enteron aisle increase; Pathogenic bacteria reduces, and forms the dominant microflora of probiotics, keeps and adjust the intestinal microecology balance.
The test of embodiment 4 fishponds detects compound micro-ecological preparation result of use of the present invention
Test is divided into three ponds, handles a and b for two, a contrast c, 2 hectares in each pond.Fishpond initial stage water source is identical, and treating pond is identical with the fry amount with the shrimp seedling that throw in the contrast pond.In the whole culture-cycle; Add two the treating pond a and the b of compound micro-ecological preparation; Do not use any microbiotic and sterilant, average 15d throws in once, and injected volume is that liquid micro-ecological preparations 30L, particle probiotics are 3 kilograms; The average 15d in pond is with a sterilant in contrast, and service condition is as shown in table 4.
The fishpond result of use of table 4 compound micro-ecological preparation of the present invention
Can know by table 4 result; The nitrogenous source pollutant load in contrast pond presents trend of rising, and two treating ponds all decrease adding bacterium after stain thing content, and wherein the treatment effect of treating pond b is more effective than handling a; Its imido nitrogen, nitrate salt, nitrate salt decline ratio are respectively 42.4%, 74.3% and 4.28%; Simultaneously show that also the little ecology of particle can sink to the bottom of water, below water body, begin to play a role that its action effect than the upper strata effect obviously.
After off-test, the aquatic animal in each pond is sampled, draw mean body weight and rate of increase, its result is as shown in table 5.
Table 5 fishes and shrimps weightening finish situation
Can know by table 5 result; The improvement that not only helps water quality with compound micro-ecological preparation of the present invention improves the fishes and shrimps surviving rate; Also help individual weightening finish, thereby significantly improve the output and the ultimate production of unit surface, wherein obvious to the individual body weight gains of the crucian of the middle lower floor that lives in water.
Experimental result proves; Probiotics product of the present invention not only safely, regulate water quality, improve the growing environment of aquatic animal, and can significantly promote the individual body weight gains of aquatic animal, increase the yield per unit area and total amount; Thereby increase the income of aquaculture, increase the benefit.
