The present disclosure relates to a feed additive composition for reducing methane production generated in the ruminant stomach of ruminant animals. Specifically, the present disclosure relates to a feed additive composition for reducing methane production comprising at least one selected from the group consisting of alliin and berberine, more specifically to a feed additive composition for reducing methane production comprising at least one selected from the group consisting of diallyl disulfide (DADS), nitrate, and eucalyptus oil. The feed additive composition according to the present disclosure may be added to the feed without additional treatment, thereby reducing the amount of methane production in the ruminant stomach without negative effects on livestock productivity. Thus, the feed additive composition can be effectively used in the ruminant animal industry.

Feed additive composition for reducing methane gas produced by ruminant animals

The present invention relates to a bacteriophage having a specific bactericidal activity against, a composition for the prevention or treatment of infectious diseases comprising the bacteriophage as an active ingredient, an antibiotic comprising the bacteriophage as an active ingredient, an animal feed or drinking water comprising the bacteriophage as an active ingredient, and a sanitizer or cleaner comprising the bacteriophage as an active ingredient. The bacteriophage of the present invention has a specific bactericidal activity againstorwith no influences on beneficial bacteria, as well as excellent acid- and heat-resistance and desiccation tolerance.

The present invention relates to a bacteriophage having a specific bactericidal activity against, a composition for the prevention or treatment of infectious diseseases comprising the bacteriophage as an active ingredient, an antibiotic comprising the bacteriophage as an active ingredient, an animal feed or drinking water comprising the bacteriophage as an active ingredient, and a sanitizer or cleaner comprising the bacteriophage as an active ingredient. The bacteriophage of the present nvention has a specific bactericidal activity against, orwith no influences on beneficial bacteria, as well as excellent acid- and heat-resistance and desiccation tolerance. Therefore, the bacteriophage can be used for the prevention or treatment of salmonellosis orfood poisoning, which is an infection disease cuased by, or, and also widely used in animal feeds, drinking water for livestock, sanitizers, and cleaners.

The present invention relates to a novel bacteriophage having an-specific bactericidal activity, a composition for the prevention or treatment of infectious diseases caused by Enterotoxigeniccomprising the bacteriophage as an active ingredient, an antibiotic comprising the bacteriophage as an active ingredient, a feed additive composition comprising the bacteriophage as an active ingredient, a sanitizer or cleaner comprising the bacteriophage as an active ingredient, and a method for treating colibacillosis using the bacteriophage. The novel bacteriophage of the present invention has a specific bactericidal activity against pathogenic, and excellent acid- and heat-resistance. Therefore, the novel bacteriophage can be used for the prevention or treatment of swine colibacillosis, which is an infectious disease caused by pathogenic, and can also be widely used in animal feed additive compositions, sanitizers, and cleaners.

The present invention relates to an isolatedsp. strain having probiotic activity. More particularly, the present invention relates to an isolatedsp. 2-4 (KCCM11107P) strain having probiotic activity. Since the strain of the present invention functions as probiotics by having an antibacterial activity against various fish pathogenic bacteria, as well as secreting helpful enzymes such as protease, amylase, cellulose, and lipase to help the digestion and absorption of the feed, the strain of the present invention can be helpfully used as a feed additive for fish and crustaceans.

The present invention relates to avirulentvariants by inactivating virulence gene clusters of(SG), a main pathogen of avian salmonellosis, and various uses thereof notably in the production of-specific lytic bacteriophages, pharmaceutical compositions and feed additives.

The present invention relates to a novel bacteriophage, more particularly, a bacteriophage that has a specific bactericidal activity againstand, a composition for the prevention or treatment of infectious diseases including salmonellosis andfood poisoning caused byor, Fowl typhoid caused by, and Pullorum disease caused bypullorum, which comprises the bacteriophage as an active ingredient, and an animal feed, drinking water, cleaner, and sanitizer which comprise the bacteriophage as an active ingredient.
