A compound of the formula:
- ##STR4## wherein each R is, independently, an alkyl group of 1 to 6 carbon atoms and each R.sup.1 is, independently, an alkyl group of 1-6 carbons or hydrogen,
A composition comprising standard animal feed in admixture with from about 20 ppm to about 1,000 ppm of the total amount of the ultimate composition of a tetraamide compound of the formula:
- ##STR5## wherein each R is independently, an alkyl group of 1 to 6 carbon atoms and each R.sup.1 is, independently, an alkyl group of 1-6 carbons or hydrogen, or the physiologically acceptable salts thereof.
A compound of the formula:
- ##STR6## wherein each R is independently, an alkyl group of 1 to 6 carbon atoms and each R.sup.1 is, independently, an alkyl group of 1-6 carbons or hydrogen, or the physiologically acceptable salts thereof.
