pregnancy-checks Endpoint

The pregnancy-checks endpoint provides bulk data for pregnancy evaluations for all animals in the herd. All animals (live, sold, and dead) are included in the response for this endpoint.

Pregnancy checks can result in three different events:

OPEN: the animal is not pregnant
PREG Pregnant: the animal is pregnant from the last breeding
PREV: the animal is pregnant, and the pregnancy was the result of a previous breeding (not the last breeding)

NOTE: This endpoint requires Bulk Data Access.

Response Schema

Data Point

Data Type

Definition

meta data

The meta data specifies historical information for the animal record.

Data Point	Data Type	Definition
modified	string	Date/time stamp (YYYY-MM-DDThh:mm:ss in 24-hour UTC Coordinated Universal Time, also known as Greenwich Mean Time (GMT) time) of the last animal update. Learn more about VAS Developer API Date/Time Formatting.
created	string	Date/time stamp (YYYY-MM-DDThh:mm:ss in 24-hour UTC time) of when the animal record was created. Learn more about VAS Developer API Date/Time Formatting.

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	Name assigned to an animal. This name is commonly reused and is not unique to the animal on farm or in the VAS suite of products.
scheme	string	Identifies the data source as VAS: com.vas.animals.name
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 dairyId information.

Data Point	Data Type	Definition
id	string	VAS-specific A data value that originates from the VAS product line. dairy identifier

pen data

The pen data specifies the animal's pen information.

Data Point	Data Type	Definition
identifier (primary pen identifier)
id	integer	VAS-specific pen identifier
scheme	string	Identifies the data source as VAS: com.vas.pen.id
alternativeIdentifiers (other pen identifiers)
id	integer	Pen number at the time of the event
scheme	string	Identifies the data source as VAS: com.vas.pen.number

The conceptionSire is the bull whose semen was used to conceive the current pregnancy.

Data Point	Data Type	Definition
alternativeIdentifiers
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.registrationId
breed	string	Sire breed name. Learn more about VAS Developer API Cow Breeds.
