Milking Curve by Group Graph

The milk curve by group presents the milking efficiency per milking group for all the valid cows milked with that group.

Note: Valid milking groups are groups with more than 15 valid cows; valid cows are only cows with AMT for first attachment ≥ 2.6min

To open the Milking Curve graph

Click the Graph drop-down arrow, then select Milk Curve Graph (Group).

A legend for each group is displayed:

The Milking Curve report displays the following data:

Indicator		Description
Date		Date for data. By default, data is displayed for the last 24 hours, but it may be extracted also for longer periods.
Session		Milking session 1= morning Milking session 2 = noon Milking session 3 = evening/night
Milked Cows		The number of cows milked during the session (identified and unidentified cows).
Milking duration		The time between the last detachment (with milk>1kg) to the first attachment (with milk >1kg).
Cow/hour		Total number of milked cows divided by the Milking duration.
Yield		Total herd yield.
Milk/hour		The average milk yield per hour.
Milk/cow		The average milk yield per cow for the session.
Milk 2 min		Milk produced in the first 2 minutes.
% Milk 2 min.		Displays the percentage of milk harvested in the first 2 minutes, out of the total milk yield. Note: This header provides data only for those cows with a yield >4 kg and without a second attachment. *Target value:45%.
Avg % milk 2 min.		Displays the percentage of milk harvested in the first 2 minutes, out of the total milk yield. Note: This header provides data for all milked cows, including those with a second attachment.
AMT		Displays the Actual Milking Time (from attachment to cluster removal). *Target value: less or equal to Target AMT.
AMT Target		Displays the calculated highest expected milking time (claw-on time) according to the farms milk production.
Flow Rate	0-15	Flow rate (kg/minute) for the first 15 seconds of milking.
	15-30	Flow rate (kg/minute) between 15-30 seconds of milking.
	30-60	Flow rate (kg/minute) between 30-60 seconds of milking.
	60-120	Flow rate (kg/minute) for the second minute of milking.
Low Flow Time		Total time the cows were milked at a low flow rate (<1kg/2.2lbs per minute. Sum of Pre-low flow time and Low flow time at removal). *Target value: less than 1 minute.
Low Flow %		Percent of time the cows were milked at a low flow rate (<1kg/2.2lbs per minute). *Target value: less than 20%.
Pre-low flow time		Time from Start Milking, until flow reached 1kg/2.2lbs per minute. Long Pre-low flow time is an indication of poor preparation of cows for milking.
Milking bimodality		Displays the number of milked cows that meet the bimodality threshold.
ID more than once		Cows identified multiple times in the parlor during a specific session.

*Target values differ between herds milked 3 times/day and 2 times/day. The target values presented are for herds milked 3 times/day.
