● Primary: Animal ID systems Tamper-proof & permanent ID Management of computerized Data Bases Animal health programs & traceability
- Reducing labor time & costs- Improving data management quality & time
Animal identification (AID): Aims
● Regulation CE 21/2004: Sheep & goat– Art. 2: All S&G after 6/1/2005, ...shall wear 1 ear
tag + 2nd device at >6 mo of age or before leavingthe farm where it was born.
– Art. 9: 2nd device: Compulsory use of e-ID after1/1/2008 (if > 0.6 Million animals).
Current European Regulations on animal identification & registration: Sheep & goat
Spain (27 Million): Started in 1/1/2006 (RD 97/2005)
►Decision CE 1560/2007Compulsory deployment of CE 21/2004 was delayed to 1 Jan 2010
…but they lose and eat it !
Retinal imaging
Retina = Sheet of nervous cells and visual receptors lining the eye’s back.
Vascular pattern = Blood vessels image.
■ Uniqueness of retinal vascular pattern of each eye during the animal life-span.
■ Differences between:● Eyes (left vs. right)● Species● Twins, clones...
■ Adapted camera and data treatment software for livestock identification (Optibrand, Fort Collins, CO).
■ Previous research on retinal identification of cattle (Allen et al., 2008; Rusk et al., 2008) and sheep (Barry et al., 2008; Rojas et al., 2009, 2010).
■ Agreement on procedures and matching score threshold by ROC curve analysis (MS = 70).
