Response Schema

Data Point

Data Type

Definition

animal data

The animal data includes multiple data points to identify the animal.

Data Point	Data Type	Definition
identifier (primary animal identifier)
id	integer	VAS-specific dairy cow identifier. This number is used in all VAS products, including PULSE and DairyComp 305. This identifier is unique to each animal in the VAS suite of products, and is the most stable and reliable source of animal identification data. dairyCowId differs from the animal's cowNumber, displayCowNumber, EID 15-digit electronic ID number associated with the animal eartag, and isoId.
scheme	string	Identifies the data source as VAS: com.vas.animals.id
alternativeIdentifiers (other animal identifiers)
id	integer	Number assigned to an animal, usually visible on the eartag: This number is commonly reused and is not unique to the animal on farm or in the VAS suite of products. cowNumber differs from the animal's dairyCowId, EID, and isoId.
scheme	string	Identifies the data source as VAS: com.vas.animals.managementNumber
id	string	15-digit ISO International Organization for Standardization, a global organization that promotes commercial and industrial standards. number associated with the animal eartag, often the same as the electronicID. If the electronicID changes, the isoId does not. The isoId is a unique on-farm animal identifier. VAS recommends against changing an animal's isoId, and it is generally considered to be more stable than the EID.
scheme	string	Identifies the data source as VAS: com.vas.animals.registrationId
id	string	15-digit electronic ID Identifier (EID) number associated with the electronic animal eartag, often the same as the IsoId. The EID of an animal changes whenever the button in the electronic tag is replaced: The EID is subject to change and is therefore not an ideal source for unique animal identification data.
scheme	string	Identifies the data source as VAS: com.vas.animals.electronicId

location data

The location data specifies the animal's location information.

Data Point	Data Type	Definition
id	string	Location identifier. For routes with “com.vas.dairies.id”, {location-id} is a VAS-specific dairy id, commonly referred to as {dairyId} when not part of an ICAR location scheme.
scheme	string	Identifies the data source as VAS: com.vas.dairies.id

animalDetail data

The animalDetail data specifies the arriving animal's information.

primaryBreed data

The primaryBreed data specifies information about the animal's breed.

Data Point	Data Type	Definition
identifier (primary breed identifier)
id	string	Breed name abbreviation. Learn more about VAS Developer API Cow Breeds.
scheme	string	Identifies the data source as VAS: com.vas.breed.code

DoNotBreed: Animal should not be bred (RC = 1)
Birthed: Animal has recently given birth or calved (RC = 2)
Inseminated: Inseminated animal (RC = 4)
Pregnant: Pregnant animal (RC = 5 or 6)
Null: Male animal (RC = 8)

lactationStatus

enum

Animal's lactation status, determined by its lactationNumber and its ReproductionCode (RC):

Lactating: Lactating animal (lactationNumber > 0 and RC = 1, 3, 4, or 5)
Fresh: Fresh animal (lactationNumber > 0 and RC = 2)
Dry: Dry animal (lactationNumber > 0 and RC = 6)
Null: The animal's status is one of the following:
- Bull Calf: Male animal (RC = 8)
- Virgin Heifer: Animal has never been bred (RC = 0)

parentage data (sire data)

The parentage data specifies information about the animal's male parentage.

Data Point	Data Type	Definition
