The chicken feed probiotic agent is prepared by virtue of the steps of evenly mixing enterococcus faecalis HEW-A131 active bacterial sludge, bacillus subtilis active bacterial sludge, saccharomyces cerevisiae active bacterial sludge and a stabilization protective agent together in the mass ratio of (0.1-0.8): (1-2.5): (0.1-0.5): 1, and then pelletizing, drying, coating and the like; the probiotic agent is capable of improving the utilization efficiency of an animal feed and saving the cost, and also capable of greatly improving the steady state of the internal environment of the digestive tract in an animal body, promoting the absorption and utilization of nutrition and promoting the growth of the animal; as a result, the productivity, the immune performance and the reproductive performance of the animal are obviously improved, the production cost is reduced and the economic benefit is increased.

The invention discloses low-protein daily ration for a growing pig under a net energy system and an application thereof, and belongs to the field of feed processing. The method comprises the steps of: taking the growing pig with the weight being 20-50kg as a research object, utilizing corn-bean pulp daily ration, reducing the protein content of the daily ration by 2% on the basis of the standard recommended by the National Research Council, simultaneously supplying lysine, methionine, threonine and tryptophan; adding mannan oligosaccharide, multivitamins, complex phosphoesterasum, probiotics and the like to form the low-protein daily ration for the growing pig under the net energy system; crushing, mixing, pelletizing then dosing, and packaging the pelletized feed and a probiotic component in a mixing manner to obtain the product disclosed by the invention. The animal feed utilization rate can be improved; the use quantity of antibiotic medicines in the feeding of animals is effectively reduced; the immunity of fed animals is improved; the security of animal meat products is improved; and the raise efficiency is also improved. The low-protein daily ration is scientific in process design, high in production efficiency, low in cost, and suitable for multi-variety and small-scale production.

A compound pig feed for improving organism immunity is characterized by comprising the following raw materials by weight: 50-60 parts of soybean meal, 30-50 parts of wheat bran, 20-40 parts of corn flour, 5-10 parts of eucommia leaf powder, 5-10 parts of echinacea powder, 8-15 parts of wormwood flour, 10-15 parts ofpurslane powder, 8-15 parts of pine needle powder, 3-6 parts of selenium yeast, 5-8 parts of cellulase, 10-20 parts of a Chinese herbal medicine preparation, 10-15 parts of a Bacillus subtilis preparation, 10-25 parts of medicinal fungi and 5-10 parts of yeast. Through scientific compounding, the feed can effectively solve the problems of low animal immunity, large amount of antibiotic and low product quality in existing feed aquaculture. The feed provided by the invention greatly improves the animal immunity, reduces the dosage of antibiotics, significantly enhances the taste and meat quality of animal products; and sensory experimental evaluation indicates that taste and quality of meat of animals using the feed are improved.

The divisional application of the invention discloses a comb growth feed achieving comb growth consistency and increasing laying rate for laying hens of 16 weeks and with laying rate of 2%, belonging to the field of feed compositions. The feed is used for the laying hens of 16 weeks and with laying rate of 2%, and can promote the propagative organ development and weight gaining; the feed is mainly prepared from the following raw materials in parts by weight: 54.365 parts of corn, 3 parts of rice bran, 2.5 parts of wheat bran, 14 parts of bean pulp, 3 parts of fermented soybean meal, 3 parts of peanut meal, 2.8 parts of sunflower seed meal, 2 parts of rapeseed dregs, 3.5 parts of distillers dried grains with soluble (DDGS), 3 parts of corn bran, 1.0 part of soybean oil, 5.2 parts of mountain flour, 0.8 part of calcium hydrogen phosphate, 0.35 part of table salt, 0.13 part of methionine, 0.12 part of 70% lysine sulfate, 0.05 part of probiotics, 0.05 part of a complex enzyme preparation, 0.012 part of phytase, and 1 part of a compound premix. By using the feed, the comb growing consistency in a comb growth phase, large eggs in a preliminary egg laying stage, fastness in speed of reaching the egg laying peak, and the relatively high laying rate can be achieved.

Described is a soluble stable liquid formulation, process for preparing, and a method of using the soluble stable liquid formulation comprising ractopamine or a physiologically acceptable salt thereof, a liquid nonionic cosolvent, and water.

The invention provides a feed additive product. The feed additive product comprises 10-15% of fructo-oligosaccharides, 10-20% of propolis, 10-25% of glossy privet fruit extract, 15-30% of rhodotorula sp. fermentation culture and 30-50% of ganoderma lucidum solid fermentation culture by mass, wherein the collection number of rhodotorula sp. is CCTCC No:M 2014592. The feed additive product has the beneficial effects that rhodotorula sp. can produce high-yield carotenoids and enrich copper; the carotenoid yield and copper content in rhodotorula sp. are effectively increased by a static culture method; and applied to feeds as a feed additive, rhodotorula sp. can provide carotenoids, B vitamins and copper ions, well replaces inorganic copper ions used in conventional feeds thanks to efficient copper enrichment capacity, has good stability, has good compatibility with other components in the diets, has a high absorption rate and a low excretion rate, is little in environmental pollution and has the effects of improving the skins and hair colors of animals and strengthening the nutritional values of the feeds.

The invention relates to a compound feed additive rich in carotenes and a preparation method thereof, belonging to the field of enzymic preparations of feeds. The compound feed additive rich in carotenes comprises the following components in parts by weight: 10-15 parts of antibacterial peptides, 10-20 parts of propolis, 10-15 parts of eucommia bark leaf extract, 15-30 parts of rhodotorula culture, 25-50 parts of morchella enzymatic powder, 5-10 parts of alfalfa powder and 0.01-0.02 part of tea polyphenol, wherein rhodotorula is rhodotorula sp. WYN1, with collection number of CCTCC No:M2014592. The compound feed additive has the beneficial effects that as used rhodotorula can produce high-yield carotenes and convert inorganic copper in a culture medium to chelated copper and enrich the chelated copper, the growth and development of animals are better promoted, the feed utilization rate is increased and the heat stability of the feed additive is improved.
