A 21 days trial was conducted to assess the effect of extensive, intensive and semi-intensive feeding practices on electro-encephalographic (EEG) recordings in six female goats (Local X Jamunapari). The study was done in three phases, phase I (GZ) comprised of extensive feeding, phase II (STF) consisted of intensive feeding and phase III (GZ+STF) consisting of semi-intensive feeding. An EEG recording was done daily in morning before grazing/feeding and in afternoon after grazing/feeding using bipolar lead system (RO-LO). The recordings of EEG amplitude and frequency for all three phases of experiment ranged from 0.95 (phase II) to 2.07 μV (phase III) and 10.50 (phase III) to 20.22 Hz (phase II), respectively. Goats in semi-intensive feeding practice showed δ wave pattern, whereas low β wave pattern was exhibited in extensive and intensive system of management. The electroencephalographic recordings can be implemented to evaluate the nemo-motor activity in goats subjected to different feeding practices.
