Detailed Description
Example 1: preparation of fermentation feedstock
Bean pulp, rice bran and corn are selected as fermentation substrates, firstly, raw materials (bean pulp, rice bran and corn) are crushed, then composite strains (bacillus, saccharomycetes and lactobacillus) are mixed with water and added into the materials, wherein the inoculation amount of the composite strains is set to be 0.025 percent, 0.05 percent, 0.1 percent, 0.15 percent and 0.2 percent, the water content is controlled to be 40 to 45 percent, the materials are uniformly mixed and packed by a breathing membrane bag, the air in the bag is exhausted during packing, then the bag is placed in a constant temperature room at 30 ℃ for fermentation, three samples are randomly selected from each gradient after the fermentation is finished to detect the small peptide content, the organic acid content, the pH value and the viable count, and various indexes and factors can be seen that the effect of the fermentation raw materials is best when the inoculation amount of the composite strains is controlled to be 0.025 to 0.2 percent, particularly when the inoculation amount of the composite strains is 0.1 percent.
TABLE 1 inoculum size Performance Table
Example 2: influence of fermentation raw materials with different contents on feeding effect
The feed consists of two parts by weight of air-dried substances: (1) and (4) a nutrition part: the feed comprises imported fish meal, domestic fish meal, flour, krill meal, soybean oil, fish oil, soybean lecithin, vitamin premix, mineral premix and monocalcium phosphate, and the specific mixture ratio is shown in table 2; (2) improving the bottom mud part: the soybean meal fermented soybean meal.
TABLE 2 constitutional Table of the nutrient part (content unit: mass%,%)
TABLE 3 improved pond sediment fraction composition (unit: mass%)
Tables 2 and 3 constitute the composition of the different embodiments of this example, and the results of the feeding of penaeus vannamei with the above-described compositions of the respective feeds show that: when the feed is not added with the fermentation raw materials (taking the fermentation raw materials in the table 3 as 0 for example), although the requirement of the penaeus vannamei on nutrition can be met, the penaeus vannamei has high morbidity, low survival rate and poor pond water quality and is not beneficial to the healthy and rapid growth of the penaeus vannamei; with the increase of the fermentation raw materials (taking the case that the addition amount of the fermentation raw materials in the table 3 is 0.5 percent and 0.8 percent as an example), the water quality is more stable, but the sewage amount and the survival rate of the bottom of the pool are still not improved; when the addition amount of the fermentation raw materials exceeds 1%, the addition amount of the fermentation raw materials is continuously increased, the water quality is more fresh and stable, the survival rate and the amount of bottom sediment dirt are improved, particularly when the addition amount of the fermentation raw materials is 5-10%, the trend is increased more remarkably, the water quality in the culture process is good, no or only trace dirt is generated at the bottom of the pond in the feeding period, and compared with the initial feeding of the penaeus vannamei, the color of the penaeus vannamei is slightly darker, but is not obvious, and no odor is generated basically; when the addition amount of the fermentation raw material is continuously increased and exceeds 10% (taking the case that the addition amount of the fermentation raw material is 12% and 15% in table 3 as an example), although the water quality improvement effect is more obvious and the dirt at the bottom of the pond is not generated basically, the cost is higher, and the deviation of the addition ratio of the soybean meal and the peanut meal is larger, which is not beneficial to the stability of the feed, so the effect brought by continuously increasing the addition amount of the fermentation raw material in the feed is not considerable.
In Hangzhou Xiaoshan area, compared with the penaeus vannamei fed with other common feeds, 20 farmers adopting the feed formula of the embodiment have the advantages of fast growth speed, consistent growth specification, 5-10 days of growth period with the same specification, 10-15% of yield improvement, 2-5% reduction of bait coefficient compared with a control group, good water quality in the culture process, no dirt at the bottom of the pond after the culture is finished, light color compared with the control group and no odor basically.
Therefore, under the condition of the same nutrient composition, when the addition amount of the fermentation raw materials is controlled to be 1-10%, the feeding effect and the pond sludge treatment effect are better, and especially when the addition amount of the fermentation raw materials is controlled to be 5-10%, the feeding effect and the pond sludge maintenance effect reach the optimal preparation.
Comparative example
The feed air-dried material comprises the following components in percentage by mass: 10% of imported fish meal, 25% of soybean meal, 15% of domestic fish meal, 20% of flour, 13% of peanut meal, 5% of cellulose, 3% of krill meal, 1.5% of soybean oil, 1.5% of fish oil, 2% of soybean lecithin, 1% of vitamin premix, 1.5% of mineral premix and 1.5% of monocalcium phosphate.
A comparative test was conducted on feeds corresponding to numbers 19 and 29 in Table 3 in example 2 (the feeds were composed of the ingredients corresponding to the numbers in tables 2 and 3) and the comparative example, and through 10 cultivation pond tests, compared with penaeus vannamei fed with the comparative example feed, the feeds corresponding to numbers 19 and 29 in Table 3 (the feeds were composed of the ingredients corresponding to the numbers in tables 2 and 3) were fed with the feeds having increased growth rates and consistent growth specifications, the growth cycle of the same specifications was shortened by 5-10 days, the yield was increased by 10% -15%, the feed coefficient was reduced by 2% -5% as compared with the control group, the water quality was good during the cultivation, no dirt was left in the bottom of the pond after the cultivation was completed, the color was lighter than that of the control group, and there was almost no odor.
The above description is provided for the purpose of describing the preferred embodiments of the present invention in more detail, and it should not be construed that the embodiments of the present invention are limited to the description above, and it will be apparent to those skilled in the art that the present invention can be implemented in many different forms without departing from the spirit and scope of the present invention.
