Feeding and Drinking Behaviour of Lactating Dairy Cows Fed on Total Mixed Ration Briquettes

The objective of the study was to examine feeding and drinking behaviour lactating dairy cows when they were introduced Total Mixed Ration (TMR) briquettes. Nine, Jersey x Sahiwal crossbred with an average live weight 275±33 kg in second week lactation randomly assigned three treatments a Completely Randomized Design (CRD) 14-day adaptation period 14-d preliminary period. observation conducted during 7 days collection CTL: guinea grass commercial feed two TMR recipe briquettes selected from previous trial TMR1 TMR2. recorded for 2 hrs after offering at 8.00 a.m. analysed using Behavioural Observation Research Interactive Software. did not show any significant difference (p≥ 0·05) among treatments. total number occurrences CTL, TMR2 18.87±8.51, 22.67±8.51 42.60±8.51, respectively while percentage length h 65.97±4.33, 59.00±4.33 61.22±4.33%, respectively. There no except occurrences. duration 30.64±55.98, 64.73±55.98 206.26±55.98 seconds TMR2, revealed that chopped forage concentrate or mixed ration does affect but may influence their behaviour.
