The present invention relates to a composition for ameliorating viral infections in nursery pigs. The composition contains the polyether ionophore narasin, and is supplied to the nursery pigs in an orally-acceptable form. The composition is effective in reducing viral shedding and the severity of diarrhea after challenge of nursery pigs with Porcine Epidemic Diarrhea Virus (PEDV).

A juvenile animal feed additive, such as for calves, that promotes animal health and growth, reduces mortality and can act as an antibiotic substitute. The additive inhibits pathogen growth resulting in lower pathogen load within the animal and reduced pathogen sheading to the environment. The additive includes bacteria that inhibit E. coli O157:H7 growth by as much as 93% and Salmonella growth by as much as 97%, together with commensurate inhibition rates against the Big-Six Escherichia coli strains. The additive includes various combinations of the following pathogen-inhibiting bacteria: Lactobacillus animalis; Enterococcus faecium; and Pediococcus acidilactici.

Composition including a pathogen inhibiting bacterial probiotic and a fructooligosaccharide (FOS) prebiotic particularly suited as a feed additive administered to juvenile animals such as calves that promotes animal health and growth, reduces scours and mortality, and can act as an antibiotic substitute. The additive inhibits pathogen growth resulting in lower pathogen load within the animal and pathogen sheading. The prebiotic-probiotic additive includes bacteria that inhibit E. coli O157:H7 growth by as much as 93% and Salmonella growth by as much as 97%, as well as the Big-Six Escherichia coli strains. The probiotic is constituted of various combinations of four pathogen-inhibiting bacteria: Lactobacillus animalis; Lactobacillus animalis; Enterococcus faecium; and Pediococcus acidilactici.

The present invention relates to isolated polypeptides having protease activity and isolated nucleic acid sequences encoding the proteases. The invention also relates to nucleic acid constructs, vectors, and host cells, including plant and animal cells, comprising the nucleic acid sequences, as well as methods for producing and using the proteases, in particular the use of the proteases in animal feed.

The present invention relates to a feed supplement and a feed containing this feed supplement, comprising 1) a homotrimer, heterotrimer, homotetramer and/or heterotetramer of a carbohydrate component selected from the group consisting of a pentose saccharide, a hexose saccharide, glucuronic and galacturonic acid, and 2) a medium-chain fatty acid (MCFA), selected from the group consisting of caproic acid (C6), caprylic (C8), capric (C10) and lauric acid (C12). The invention also refers to the use of the feed supplement or feed in order to improve the efficiency of animal production, such as weight gain, feed conversion, nutritive value, health and wellbeing through the selective elimination of enteropathogens.
