Case #1 involved a 26-month-old first parity Friesian that weighed approximately 600 KG. During pregnancy the animal showed rigidity of the back limbs. It also showed difficulty in rising and walking, and feed intake was low and variable. An ABM was attached to the tail and activated. The following day the animal had clearly improved. Ten days later the ABM device was removed because the animal had recovered completely without additional treatment.
Case #2 involved a 40-month-old Friesian that did not expel the placenta during calving. The animal did not eat or ruminate and was recumbent, showing signs of Ketosis. An ABM device was applied to the tail at 8:00 A.M. and activated. Within three hours the animal began to ruminate. In the afternoon the animal walked to the feed manger and began to eat. After three days the ABM was removed and the animal was returned to the herd without any additional treatment.
Case #3 involved a 26- to 27-month-old animal. One week following parturition she was inappetent and totally refused feed. The feces were dark, and mixed with mucous. Elevated levels of undigested feed were observed in the feces. The cow was treated for Ketosis using several products prescribed by the herd veterinarian. The animal's condition did not improve. Four days later an ABM device was applied and activated. Within two days following ABM activation the cow began to eat hay. Within 5 days milk production -- which had fallen to 8 kb per day -- doubled.
In all three cases the animals were owned by commercial dairies feeding locally produced forages and grains typical for the region.

Many diseases and management conditions reduce feed intake thereby limiting the health and production of dairy cattle. ABM technology offers veterinarians a new on-invasive, non-chemical alternative to the management of inappetance.
