GENETICALLY ENGINEERED RUMEN BACTERIAL STRAINS

摘要

Strains of rumen bacteria are provided which havebeen genetically altered to express a protein rich in aminoacids which are ordinarily deficient in lactating ruminants.Certain of the modified strains also produce bacteriocin,either naturally or due to genetic modification, which has theeffect of improving rumen function, facilitating theestablishment of the strain in the rumen and altering thecontent of unsaturated fat and total fat in milk.Introduction of these strains into the rumen of ruminantanimals can result in the production of milk with a higherprotein content, a higher proportion of unsaturated fat and alower total fat content.
