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.

The invention discloses a grass carp set meal feeding method according to the law of natural variation of dissolved oxygen in a water body. The daily grass carp set meal feeding mode is determined according to the daily dissolved oxygen level in a pond water body, in a low dissolved oxygen period, feed with a low nutrient level is fed, and in a high dissolved oxygen period, feed with a high nutrient level is fed. The set meal mode of grass carp in a growing period is put forward according to the whole-day natural dissolved oxygen variation law in the pond, thereby accurately meeting the physiological needs of the grass carp in different physiological states. The set meal mode is reasonably designed, and the distribution of the feeding amount per meal is also based on a large number of research and statistics results. A breeder can directly observe the feeding status of the fish, the feeding amount can be timely adjusted, the fed feed is basically eaten by the fish, the residual bait isless, water pollution caused by excessive feed input can be avoided, and the freshness of the breeding water environment is ensured. The grass carp feed utilization efficiency can be improved, the grass carp feed coefficient is reduced, the breeding cost is reduced, and the comprehensive benefits of breeding are improved.

The invention belongs to the field of animal feed and particularly relates to sheep feed based on bamboo shoot shells. The sheep feed based on the bamboo shoot shells contains the ensiled bamboo shoot shells. The use amount of the ensiled bamboo shoot shells accounts for 30-70% of the weight of coarse fodder in daily ration or accounts for 23-47% of the weight of the daily ration. According to the sheep feed based on the bamboo shoot shells, the ensiled bamboo shoot shells can be used for replacing leymus chinensis to serve as the feed of hu sheep, and the growth performance of the hu sheep will not be influenced. The ensiled bamboo shoot shells can be used for replacing the leymus chinensis to serve as cattle feed, and the growth performance of cattle will not be influenced. When the ensiled bamboo shoot shell feed is used, 4% of molasses is added, and the feed intake and the daily weight gain can be increased; the feed conversion efficiency is improved, the feed to weight ratio is lowered, and the effect is superior to the effect achieved when the ensiled bamboo shoot shells or the molasses are used independently.

The invention relates to a fattening sheep compound feed for reducing fat deposition. The fattening sheep compound feed comprises the following components in parts by weight: 0.05-0.5 part of a compound additive obtained by mixing betaine, chitosan oligosaccharide and L-carnitine, 25-35 parts of corn, 1-3 parts of bran, 3-7 parts of soybean meal, 5-10 parts of oil residue, 10-15 parts of silage, 3-7 parts of corn germ meal, 30-40 parts of Chinese wild rye, 0.1-1 part of table salt, 0.5-1.5 parts of stone powder, 0.1-1 part of calcium hydrogen phosphate and 0.5-1.5 parts of a mixture of vitamins and trace elements. The compound feed provided by the invention can increase the final weight, average daily gain, average daily feed intake and feed conversion rate of the fattening sheep while remarkably reducing the absolute weight of the fattening sheep tail and rumen fat and the total fat, the proportion of the fattening sheep tail and rumen fat and the total fat to the live weight before slaughtering and the proportion of the perirenal fat to the live weight before slaughtering in comparison with a control group; thus, the compound feed provided by the invention can noticeably reduce the fat content without influencing the growing performance and slaughtering performance of mutton sheep; and moreover, the compound feed is safe to use and has a great promotion value.

The invention discloses a biologic concentrated feed for pigs. In a formula of the biologic concentrated feed, a trace element premix, peptide type protein raw materials and functional fat, in an appropriate compounding ratio, are used. The pretreated peptide type protein raw materials are selected for use, and anti-nutritional factors in a traditional protein source are eliminated, so that digestion and absorption of the feed and the production performance of the pigs can be increased, and the feed conversion rate can be reduced; the formula is designed through digestible amino acids, the level of crude proteins is low, and the digestibility of the peptide type protein raw materials is high, so that the growth performance of the pigs is not influenced, and waste of protein resources and environment pollution are reduced; and homogenized and emulsified functional fat is selected for use, so that absorption and utilization of fat by the pigs can be increased. When the biologic concentrated feed is used for suckling piglets, immunity and stress resistance of the suckling piglets can also be reinforced; when the biologic concentrated feed is used for sows, the lactation amount and thequality of dairy products can be increased, and the survival rate, the new-born weight, the daily gain and the weaned brood weight of the suckling piglets can be increased; and therefore, the biologic concentrated feed is an efficient biologic concentrated feed for the pigs, and is good in application prospects.
