Independent Claim
24 words
An antianemic composition for veterinary use which comprises a complex of a dextran carboxylic acid obtained by a microbial process with an iron salt.
Claim 2
Dependent Claim
73 words
An antianemic composition for veterinary use according to claim 1, wherein the dextran carboxylic acid is obtained by allowing a microorganism which belongs to the genus Pseudogluconobacter and is capable of oxidizing the hydroxymethyl group and/or OH-containing hemiacetal moiety of a dextran having hydroxymethyl group and/or hemiacetal hydroxyl group to carboxyl group, or its processed material to act on a dextran having such group to produce the corresponding carboxylic acid, and recovering it.
Claim 3
Dependent Claim
16 words
