Abstract
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.
Description
technical field [0001] The invention belongs to the technical field of lithium fish feed and its preparation, and in particular relates to a special feed for carp in alkalinity waters and a preparation method thereof. Background technique [0002] Saline-alkali waters exist widely in nature, and have the characteristics of high carbonate alkalinity, high pH, and various types of water quality. There are many saline-alkali waters in my country, accounting for about 55% of the total lake area in the country, and the low-lying saline-alkali water is about 6.9×10 8 Mu, and it shows an increasing trend year by year, but most of them are in an idle state because they cannot be directly used by humans, animals and agriculture. Therefore, how to rationally and effectively develop and utilize vast saline-alkaline water resources has become an urgent and arduous task. However, under the conditions of aquaculture in carbonate-alkalinity waters, the acid-base balance in the fish bo...
