Abstract
The invention discloses a mixed composite microbial feed for freshwater fish and a production method thereof, wherein the mixed feed contains no antibiotics, no hormones and no harmful additives. The mixed composite microbial feed for freshwater fish comprises the following components, by weight, 8-10% of biologically fermented cottonseed rapeseed meal, 3-5% of polypeptide biological blood powder, 80-84% of mixed feed powder, 3-5% of a feed additive and 1-5% of plant oil. Macromolecular protein raw materials are decomposed into polypeptides and small peptides through an exogenous enzyme and the microbe fermentation, so antinutritional factors of non-starch polysaccharides and the like in the feed are degraded, and the feed utilization rate is improved; the feed contains no antibiotics, no hormones and no harmful feed additives; and the freshwater fish fed with the feed of the invention has the characteristics of fast growth speed and strong disease resistance. A mixed high protein biological feed for adulthood grass carp, which contains 35% or 32% of crude proteins, can be produced through above technology, the generation of hepatobiliary syndrome and three diseases of the grass carp is effectively reduced, and problems that the adulthood grass carp cannot be fed with the high protein feed and the feed of mix-cultured fish is difficult to select are solved; and the freshwater fish fed with the feed of the invention has the advantages of tough fish flesh and delicious taste. The method of the invention has the advantages of simplicity, no need of special equipment, and suitableness of the industrialized production.
Description
technical field [0001] The invention belongs to the technical field of animal feed, and relates to the production of a compound feed for freshwater fish, in particular to a compound microbial feed suitable for freshwater fish without antibiotics, hormones and harmful additives and a production method thereof. Background technique [0002] Fish is a basic nutrient for humans and one of the most important nutrients. In order to improve the production performance of freshwater fish and prevent bacterial diseases, the early method was to add some antibiotics, such as olaquindox, nitrofurans, bacitracin zinc, etc., to the feed of freshwater fish. This method is simple and can achieve the desired effect, but its negative effects are: 1. The antibiotics that have not been metabolized are accumulated in the fish, causing the antibiotics in the fish to exceed the standard, or even seriously exceeding the standard, endangering the health of consumers; 2. Long-term use Antibiotic feed...
