| dc.description.abstract | The behavior of FH dairy cows can be used to identify whether the animals are healthy or stressed as a result, it will have an impact on the milk production productivity. Friesian Holstein dairy cows may respond positively to additional feeding of depolarizing valves leaves. The goal of this study is to see how more depolarization valves affect dairy cow behavior throughout the third lactation phase. The Friesian Holstein dairy cows used in this study were three cows, which were divided into three treatment groups with one tail, namely P0 (complete feed of PT GGL), BKD ( complete feed of PT GGL and 100 g depolarization valves powder) and PKD (complete feed of PT GGL and 100 g depolarization valves pellet). The observed variables were frequency (e.g., eating, rumination, rest, locomotion, drinking, and elleminative). Data is presented in chart and analyzed descriptively. The result showed that the administration of depolarizing valves has volatile effect on all behavioral frequencies at each treatment level, namely by comparing (P0 and BKD), ( P0 and PKD) and (BKD and PKD).
