Response Schema

Data Point	Data Type	Definition
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.
cowNumber	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.
isold	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.
electronicId	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.
cowName	string	Cow name
lactation	integer	Current lactation number
reproductionCode	integer	Reproduction code: 0: HEIFER - female, heifer 1: DNB Do Not Breed - Do not breed 2: FRESH - Fresh cow 3: OK/OPEN - OK to breed 4: BRED - Bred (by AI artificial insemination or bull) 5: PREG Pregnant - Pregnant animal 6: DRY - Dry animal 8: MALE - Male animal
isMale	boolean	Identifies the animal as male
birthDate	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 animal birth date. Learn more about VAS Developer API Date/Time Formatting.
