Datamars Livestock takes into consideration the 'gut fill' of an animal when calculating the weights for a WOW system.

What is 'gut fill'?

Gut fill is the percentage of an animal’s liveweight which can be attributed to the contents of its stomach. Gut fill can be affected by:

  • water access and water quality

  • time since feed and/or water access

  • feeding levels and type of feeds

How does 'gut fill' affect WOW weights

A WOW system will be located in a paddock or in a milking shed/parlour where animals have a continuous supply of food and water. This means that animals will often be weighed when their stomachs are full.

Datamars Livestock software requires two weeks of weights from a WOW solution in order to manage variations caused by gut fill and to calculate accurate weight assessments.
