Long-hauled calves averaging 293 lb
were allotted to groups fed with or without
protected lysine-methionine (Smartamine
ML®). Protected lysine-methionin e did not
improve ADG in the first 28 days but did improve
ADG from 29 to 56 days. It also
reduced morbidity (16.1 vs 34.2%) from day
29 to 56. Based on this research, the
response of long-hauled calves to protected
lysine-methionine in the diet appears to occur
after they have recovered from the stress of
shipment.
