Low-carbon environment-friendly conservation-stage piglet feed

InactiveCN103621826ALow fecal nitrogen and phosphorus contentImprove growth performanceFood processingAnimal feeding stuffPhytaseFeed conversion ratio
The invention discloses low-carbon environment-friendly conservation-stage piglet feed. Based on physiological characteristics of conservation-stage pigs, multiple raw materials are combined with one another, the nutrients are complementary, the protein content of the feed is about 16 percent, functional additives such as phytase, a compound enzyme preparation, a compound acidifying agent, a compound microecological preparation and oligosaccharide are added into the piglet daily ration, the growth performance is the best, the apparent digestibility of the crude proteins is the highest, a feed conversion ratio is the lowest, and the content of nitrogen and phosphorous in fecaluria is the lowest. Compared with a control group which has the high protein content (19%) and is free of functional additives, the feed provided by the invention has the advantages that the apparent digestibility is improved by about 10 percent, the feed conversion ratio is reduced by about 9 percent, and the nitrogen content in fecaluria is reduced by 38 percent; compared with daily ration which has the protein content of 17-18 percent and contains a certain amount of functional additives, the feed provided by the invention has the advantages that the apparent digestibility is improved by 10 percent, the feed conversion ratio is reduced by 1.8 percent, and the nitrogen content in fecaluria is reduced by 25-35 percent. Therefore, after a certain amount of additives are added in the low-protein amino acid balanced daily ration, the apparent digestibility of piglet to crude proteins is obviously improved, the feed conversion ratio is reduced, the emission of N and P in the fecaluria is reduced, the production performance of piglets is greatly improved, the environmental pollution is effectively reduced, and the requirements of low carbon and environment friendliness are met.

Preparing and processing method of health-preservation oil obtained from shrimp heads

The invention discloses a preparing and processing method of health-preservation oil obtained from shrimp heads. The health-preservation oil is prepared through the following steps: using the heads of fresh living shrimps or iced fresh shrimps or refrigerated shrimps as raw materials, using edible oil as an extraction agent, using medicinal and edible spices, pretreating raw materials so as to obtain minced mixed shrimp head materials, and leaching the minced mixed shrimp head materials through microwaves in vacuum; performing solid-liquid separation so as to obtain semi-finished shrimp head oil; and seasoning the semi-finished shrimp head oil, and dehydrating the seasoned semi-finished oil obtained from shrimp heads head oil so as to obtain the health-preservation oil obtained from shrimp heads. The health-preservation oil obtained from shrimp heads processed and prepared by the preparing and processing method disclosed by the invention not only has the characteristics of resisting oxidation of shrimp type fat and preventing oxidative deterioration, promotes the flavor of products, improves the health preservation function, increases the types of shrimp type processed foods, and satisfies the needs of people for shrimp type products which are rich in nutrition and prominent in health-care functions.

Bacillus amyloliquefaciens B7 with immune growth promoting effect and application method of bacillus amyloliquefaciens B7

The invention discloses bacillus amyloliquefaciens B7 with an immune growth promoting effect and application method of the bacillus amyloliquefaciens B7. The bacterium is named as bacillus amyloliquefaciens B7 according to the classification, and is collected in the China Center for Type Culture Collection, with the collection number of CCTCC NO: M 2016128. An experiment shows that the bacterium disclosed by the invention can improve the immune function of cynoglossus semilaevis and effectively resist invasion of pathogenic microorganisms; the disease morbidity is reduced to 4 percent or below, and the aquaculture survival rate is increased to 96 percent or above; the digestive enzyme activity and the feed utilization rate of the cynoglossus semilaevis are improved; the food coefficient is reduced by 12 percent or above, and the specific growth rate is increased by 4 percent or above; the use amounts of antibiotic and chemical medicines are effectively reduced, the environmental pollution is relieved, the quality safety of an aquaculture product is guaranteed, and the bacillus amyloliquefaciens B7 has a good ecological benefit. The key technical problem in disease damage prevention and treatment, which restricts healthy development of cynoglossus semilaevis aquaculture industry is solved, and the bacillus amyloliquefaciens B7 realizes environmentally friendly, efficient and healthy aquaculture.

Zinc-rich bacterial strain and application thereof

The invention relates to a zinc-rich bacterial strain and application thereof. The zinc-rich bacterial strain is characterized in that the bacillus subtilis is domesticated by gradually increasing theconcentration of zinc sulfate, so as to obtain a bacillus subtilis strain; the tolerance of the bacillus subtilis is obviously improved, the zinc content of the bacillus subtilis is increased, the content of crude protein, enzyme, small peptide, amino acid and the like in the bacillus subtilis strain is increased, the microecology is integrated with the organic zinc, the convenience in use is realized, and the application effect is good; the prepared bacillus subtilis strain zinc not only has the advantages of bacillus subtilis, but also the inorganic zinc is converted into thallus organic zinc, the utilization rate of trace metal elements by animals is greatly improved, the biology function of the organic zinc is well utilized, and the purpose of one bacterial strain with two functions is realized; because the utilization rate of organic zinc is improved, the usage amount and discharge amount of inorganic zinc in feed are greatly reduced, and the pollution to ecological environment is reduced; the important technical support is provided for the development of novel animal microecological preparations and 'amount-reduction' usage of trace elements.

Special feed for cyprinus carpio under alkaline water area culture conditions and preparation method thereof

The invention relates to a special feed for cyprinus carpio under alkaline water area culture conditions and a preparation method thereof and belongs to the technical field of cyprinus carpio feeds and preparation thereof. The feed is prepared from soybean meal, fish meal, middlings, bean oil, fish oil, phospholipid, choline chloride, sodium dihydrogen phosphate, mineral element premix, multivitamins, methionine, threonine, sodium butyrate, alpha-ketoglutaric acid and N-carbamylglutamic acid according to certain parts by mass. Through adding the sodium butyrate, the acid-base equilibrium of intestinal tracts can be changed, the activity of digestive enzymes is improved, the growth of probiotics is promoted to improve intestinal tract health, and growth is promoted. The alpha-ketoglutaric acid and the N-carbamylglutamic acid can convert ammonia resulting from catabolism of proteins into glutamine and arginine in a metabolism process, and nitrogen generated from metabolism is transferredinto amino acids again for reutilization, so that a toxic action on fish bodies caused by the ammonia and the nitrogen is reduced, and the utilization ratio of the nitrogen is increased; meanwhile, the generated glutamine and arginine can also be used for improving immunizing and oxidation resisting functions of organisms.
