Abstract: Disclosed are methods for administering hop acids to alter the microbial population of the gastrointestinal tract of animals and to inhibit the growth of pathogenic organisms in the gastrointestinal tracts of animals. Also disclosed are methods of increasing weight gain, feed efficiency, milk production in mammals, and egg and meat production in poultry by administering hop acids. Also disclosed are animal feeds containing hops and hop acids.

Abstract: Olefin polymerisation uses catalysts based in pi-arene complexes of lanthanide metals in particular such catalysts supported on hydrophobic or hydroxylic surfaces particularly of alumina or silica halide surfaces particularly magnesium chloride. Such catalysts will polymerise ethylene and also propylene to give a largely isotactic polymer without using an electron donor to enhance stereo regularity. They also do not require co-catalysts to activate polymeriscation.

Abstract: A transition metal composition is obtained by treating at least one particulate support material with at least one organomagnesium compound, at least one cleavage agent and at least one transition metal compound of Groups IVA, VA or VIA of the Periodic Table. The support material is typically a metal oxide, such as alumina or silica. The orgaomagnesium compound is typically a dialkyl magnesium compound such as dibutyl magnesium. The cleavage agent may be an amine, a thioalcohol, an ester, a carboxylic acid or particularly an alcohol such as n-butanol. The transition metal compound is added after the organomagnesium compound and the cleavage agent and is typically titanium tetrachloride. The product may be used as a catalyst component to polymerise an olefine monomer such as ethylene.
