Effects of gamma-aminobutyric acid administration on health and growth rate of group-housed Japanese Black calves fed using an automatic controlled milk feeder

The efficacy of a gamma-aminobutyric acid (GABA) preparation in improving general health condition and growth rate was evaluated in suckling Japanese Black beef calves housed together and fed using an automatic milk feeder. The GABA preparation was administered from 4 to 10 d postpartum until weanin...

Description
Summary:	The efficacy of a gamma-aminobutyric acid (GABA) preparation in improving general health condition and growth rate was evaluated in suckling Japanese Black beef calves housed together and fed using an automatic milk feeder. The GABA preparation was administered from 4 to 10 d postpartum until weaning. A significant difference in mean body weight was observed at 3 and 8 weeks after introduction of the GABA preparation. The calves in the GABA group tended to require less medication than those in the control group (3.0 d/calf for GABA; 7.6 d/calf for the control; P=0.06). The health statuses of the 2 groups may be reflected in their blood parameters. GABA may possibly have etiotropic effects in group-housed calves fed using an automatic milk feeder.
