[QUOTE="Domjan, post: 390281, member: 6102"] You have to record the milking data in pit (milk kg and time values each cow), if there is udder washing. (When I milked in morning then I recorded the data in evening, etc., etc.). I was unable to explore this regularity without adequate data; I was able to discover it only in milking pit. See it to believe it. If milking data (order(!) and milk kg each cow) is available from your system then you have to convert it into e.g. Excel, Access format. You have to group the data by milking (morning, midday, evening) and by herd group. You have to calculate the average milk yield by milking groups. For example: There are 2 herd groups (A and B) in Kibbutz Alef (2*120 cows). There are 2*12 milking places in the milking parlour. So there are 10 milking group per herd group. You have to calculate (e.g.): Average yield of A1 in morning with average time value Average yield of A2 in morning with average time value Average yield of A3 in morning with average time value Average yield of A4 in morning with average time value Average yield of A5 in morning with average time value Average yield of A6 in morning with average time value Average yield of A7 in morning with average time value Average yield of A8 in morning with average time value Average yield of A9 in morning with average time value Average yield of A10 in morning with average time value Average yield of B1 in morning with average time value Average yield of B2 in morning with average time value Average yield of B3 in morning with average time value Average yield of B4 in morning with average time value Average yield of B5 in morning with average time value Average yield of B6 in morning with average time value Average yield of B7 in morning with average time value Average yield of B8 in morning with average time value Average yield of B9 in morning with average time value Average yield of B10 in morning with average time value You have to compare the averages and to locate the time value of maximal average milk yield. For example: Average milk yield of A7 is the maximum (in morning). A7/A1 is amount of the extra milk (e.g. 16%). Time value of A7 is 50 minutes (compared to the starting time of udder washing) Average milk yield of B7 is the maximum (in morning). B7/B1 is amount of the extra milk (e.g. 15%). Time value of B7 is 52 minutes (compared to the starting time of udder washing) Average milk yield of A5 is the maximum (in evening). A5/A1 is amount of the extra milk (e.g. 14%). Time value of A5 is 28 minutes (compared to the starting time of udder washing) Average milk yield of B5 is the maximum (in evening). B5/B1 is amount of the extra milk (e.g. 15%). Time value of B5 is 32 minutes (compared to the starting time of udder washing). If you don’t have knowledge about starting time of udder washing then you can compare to the first milking group, too. If there will be significant difference then my thesis is right. [/QUOTE]
