Abstract

A bolus for administration to a ruminant animal and for retention in the rumen or reticulum of the animal, the bolus having an electronic identification device housed therein with an identification code encoded in the electronic device, and a permanent visual representation of the identification code on and/or within the bolus.

Claims

1. A bolus for oral administration to a ruminant animal and for retention in the rumen or reticulum of the animal, the bolus having an electronic identification device housed therein with an identification code encoded in the electronic device, characterized by a permanent visual representation of the said identification code on the bolus.

2. A bolus according to claim 1 characterized by a second visual representation of the said identification code, the second visual representation being on the exterior surface of the bolus and being removable therefrom so that it can be transferred to a record system before the bolus is administered to an animal.

3. A bolus according to claim 1 characterized in that the permanent visual representation comprises a label carrying a bar code in addition to a numeric representation of the code.

4. A bolus according to claim 1 characterised in that the permanent visual representation is protected by an outside portion of the bolus.

5. A bolus according to claim 4, characterised by an outer shell which is at least partly of transparent material through which the permanent visual representation is readable.

6. A bolus according to claim 5 characterized by an inner core within the outer shell, the inner core comprising a matrix material together with the electronic identification device, the specific gravity of the bolus being adjustable by varying the thickness of the outer shell.

7. A bolus according to claim 6, wherein the matrix material includes glass beads to increase the specific gravity of the bolus.

8. A bolus according to claim 5 wherein the outer shell comprises glass.

9. A bolus according to claim 5 characterized by an inner core within the outer shell, the inner core comprising a matrix material together with the electronic identification device, the specific gravity of the bolus being adjustable by varying the composition of the matrix material.

10. A bolus according to claim 5 wherein the outer shell comprises transparent plastics material.

11. A bolus according to claim 1, characterized in that it also houses a temperature sensor and an electronic device for transmitting data from the temperature sensor in response to an interrogation unit outside the animal.

12. A bolus according to claim 11 characterised in that the identification code and the temperature data are readable in a single numeric or alphanumeric representation, with the temperature data before or after the identification code.

13. A bolus for oral administration to a ruminant animal and for retention in the rumen or reticulum of the animal, the bolus having an electronic identification device housed therein with an identification code encoded in the electronic device, characterized by a permanent visual representation of the said identification code within the bolus.

14. A bolus according to claim 13 characterized by a second visual representation of the said identification code, the second visual representation being on the exterior surface of the bolus and being removable therefrom so that it can be transferred to a record system before the bolus is administered to an animal.

15. A bolus according to claim 13 characterized in that the permanent visual representation comprises a label carrying a bar code in addition to a numeric representation of the code.

16. A bolus according to claim 13 characterized in that the permanent visual representation is protected by an outside portion of the bolus.

17. A bolus according to claim 16, characterized by an outer shell which is at least partly of transparent material through which the permanent visual representation is readable.

18. A bolus according to claim 17 characterized by an inner core within the outer shell, the inner core comprising a matrix material together with the electronic identification device, the specific gravity of the bolus being adjustable by varying the thickness of the outer shell.

19. A bolus according to claim 18, wherein the matrix material includes glass beads to increase the specific gravity of the bolus.

20. A bolus according to claim 19 characterized in that the identification code and the temperature data are readable in a single numeric or alphanumeric representation, with the temperature data before or after the identification code.

21. A bolus according to claim 17 characterized by an inner core within the outer shell, the inner core comprising a matrix material together with the electronic identification device, the specific gravity of the bolus being adjustable by varying the composition of the matrix material.

22. A bolus according to claim 17 wherein the outer shell comprises glass.

23. A bolus according to claim 17 wherein the outer shell comprises a transparent plastics material.

24. A bolus according to claim 13, characterized in that it also houses a temperature sensor and an electronic device for transmitting data from the temperature sensor in response to an interrogation unit outside the animal.
