Labeling Blood Samples: 

Labeling Blood Samples

Slide13: 

Bar code label with 15-digit EID goes on the tube and is shipped to the lab

Slide14: 

The lab enters the samples electronically. Results are returned electronically. Results are downloaded into the laptop The tag is read and results appear

Slide15: 

Sorting

Slide16: 

Using EID Ave. time to collect Samples = 200/hr. Ave. Lab. Time = 5days Ave. time to read Brand and sort = 420/hr.

Concluding Comments: 

Concluding Comments There is more than one way to ID animals. Long-term retention will be an issue. On-farm value-added management tools will continue to grow with implementation. 'Moving at the speed of commerce' is easier said than done.
