The existing property is (in our case) normally used to transmit the certified milk-amount to a milk-recording organization. But this amount may not contain separated amounts. On the other side, there are e.g. feeding-calculations which intend to calculate feed for animals on the complete milk-production (including separated amounts) of an animal. Therefore, at least a second milkingMilkWeight is useful. In addition, the third milkingMilkWeight may extend the former one containing also pre- and post-milking weights.
We agreed to go back to the milk recording organisations and manufacturers and ask how milking weights (separated, discarded, certified, and total) are represented so we can get the names right.
We discussed on 7 March 2024 and agreed:
milkingMilkWeight
within the existing icarMilkingVisitResource
should remain the standard, "certified" milk weight that is used in genetic evaluations in line with the ICAR Guidelines.separatedMilkWeight
(for a separated quarter), discardedMilkWeight
(or similar, for milk discarded during cleaning of the teat), and totalMilkWeight
(the sum of these and the milkingMilkWeight
) should be additional attributesmilkCharacteristics
.We also noted that at the moment the characteristic
property of icarMilkCharacteristicType
is just a string defined by a description. Really this should be an enumeration. However, this could be a breaking change. We should create the enumerated type, and at the moment just link or reference this from the description of characteristic
. This would greatly improve documentation.
We decided to close this item
I'm adding this issue to allow discussion of PR #434 added by @AndreasSchultzGEA to allow discussion. The PR adds two (not required) additional weights - certified milk weight and total milk weight.
Andreas will add an explanation of the purpose for these proposed changes.
