Micro-ecological feed capable of improving intestinal function of pelteobagrus fulvidraco fries in feeding habit conversion period

Abstract

The invention discloses micro-ecological feed capable of improving an intestinal function of pelteobagrus fulvidraco fries in a feeding habit conversion period. The micro-ecological feed contains the following main functional raw materials in parts by weight: 0.01-0.02 part of bacillus licheniformis with the bacteria content of 2*10<10> per gram, 1-1.5 parts of a water extract of whole flower of honeysuckle, 0.05-0.2 part of fructooligosaccharide and 0.01-0.03 part of vitamin E. The feed is capable of improving the intestinal function of the pelteobagrus fulvidraco fries in the feeding habit conversion period. The feed formula is complete and rich in nutrition, and therefore, the feed is capable of promoting the growth performance of the pelteobagrus fulvidraco fries, improving the micro-ecological environment in the intestine of the pelteobagrus fulvidraco, restraining the planting growth of harmful bacteria on the intestine epithelium, improving the absorption and the utilization of the pelteobagrus fulvidraco fries on the nutritive elements, enhancing the body constitution of the fries, and decreasing the enteritis morbidity of the pelteobagrus fulvidraco, thus enabling the pelteobagrus fulvidraco to be non-polluted environment-friendly aquatic products, increasing the economic benefit for feed producers and farmers and being beneficial to the healthy and sustainable development of the fishery.

Description

technical field [0001] The invention belongs to the technical field of aquatic product compound feed, and specifically relates to a micro-ecological feed and a production method thereof for improving the intestinal function of peltrow catfish fry in the diet conversion period. Background technique [0002] Pelteobagrus fulvidraco belongs to Siluriformes, Pelteobagrus genus, is a benthic carnivorous fish, with high protein content, low fat content, rich nutrition, tender meat, high economic value, and is an emerging Freshwater aquaculture species, at present, the artificial breeding technology of yellow catfish has basically matured, and the artificial large-scale breeding continues to expand, and the requirements for artificial compound feed are becoming more and more urgent, especially the research and development of artificial compound feed during the diet conversion period of yellow catfish fry. The newly hatched fry are nourished by the yolk in the yolk sac. When the sw...

Problems solved by technology

One of the reasons for the analysis is that the transitional stage of transition from endogenous nutrition to external nutrition during the opening stage of fry is the "sensitive period" for the cultivation of yellow catfish, and its opening bait is mainly rotifers, which is relatively simple, which will cause nutritional deficiencies during the opening stage , the mortality rate is relatively high; the second reason is that the yellow catfish is a gluttonous carnivorous fish, and it is fed with artificial compound feed with high nutritional content during the feeding habit conversion period, the fry intake increases, and the gastrointestinal tract cannot digest the various components in the feed in time. Nutrients, causing intestinal micro-ecological environment disorder, increasing the number of harmful microbial flora, inhibiting the growth of beneficial bacteria, causing enteritis, increased mortality, seriously affecting the healthy development of the production and breeding industry of yellow catfish
