The invention relates to direct-fed microbials for use in E. coli inhibition in animals in combination with antibiotics selected from the group consisting of ceftiofur, oxytetracycline, tulathromycin, and lincomycin. More particularly, the invention relates to isolated Bacillus strains 2, 3, 4, 5, 9, 57, 71, and 126, and strains having all of the identifying characteristics of these strains, for a use comprising the above-mentioned use.

The present application relates to: an anticoccidial composition comprising violacein, a violacein derivative and/or a salt thereof; and a use thereof. A composition comprising violacein, according to one embodiment, has excellent effects of direct killing of protozoa that can induce coccidiosis, inhibiting the cell penetration of the protozoa and/or inhibiting the intracellular proliferation of the protozoa, and preventing, alleviating, and treating in vivo coccidiosis.

The present invention relates to a novel antibacterial peptide and a composition comprising the same as an active ingredient. The novel antibacterial peptide of the present invention exhibits excellent antibacterial activity against antibiotic-resistant bacteria as well as Gram-positive bacteria and Gram-negative bacteria and is low in cytotoxicity and, as such, can be advantageously utilized as an active ingredient in an antibiotic, a cosmetic composition, a food additive, a feed additive, a biotic pesticide, a quasi-drug product, and the like.

Described herein are compositions and methods to be used in controlling pests, such as arthropods, nematodes, helminths, insect pests, internal parasites, and external parasites. Such compositions make use of at least a blend of one or more essential oils and, optionally, additional components, such as surfactants, emulsifiers, solvents, additives, and inerts. Compositions can be applied to a variety of locations to control pests or can also be added into feed or foodstuffs to afford internal pest control.
