Method of increasing the fat content of colostrum or milk from maelkegivende lakes

摘要

The fat content of sows' milk is increased thereby increasing the energy supplied to the sow's piglets, by administering a phenethanolamine of formula (I): CHEM wherein: R is hydrogen, hydroxy, methoxy or amino; R1 is hydrogen or cyano; R2 is C2-C4 alkyl or a group of formula (II) CHEM R3 is hydrogen or methyl; R4 is hydrogen, hydroxy, fluoro, nitro or carbamoyl; provided that: R and R4 are not both hydrogen; R4 is not hydroxy when R is hydrogen; R is hydrogen or amino when R1 is cyano; R is hydrogen, hydroxy or methoxy when R1 is hydrogen; R2 is C2-C4 alkyl when and only when R1 is cyano; or a physiologically acceptable acid addition salt thereof.
