1. A method for detecting boar taint in a pig comprising:
- (a) combining in a reaction buffer a sample from said pig and anti-skatole antibodies to form a reaction mixture;
(b) incubating said reaction mixture for a period of time sufficient to form an antibody-skatole complex with any skatole present in said reaction mixture; and
(c) determining the amount of antibody-skatole complex as an indication of boar taint in said pig.

Abstract
A method for detecting boar taint in a pig sample is provided. Anti-skatole antibodies are combined in a reaction buffer with a pig sample to form a reaction mixture. After incubating, the amount of skatole-antibody complex formation is determined. In a particular embodiment, the method utilizes solid substrate-affixed antibodies in a competitive inhibition assay with an enzyme-labeled skatole analogue. Kits facilitating the method are also provided.

8. A method for detecting boar taint in a pig comprising:
-
(a) combining in a reaction buffer a labeled skatole analogue, a blood sample from said pig and anti-skatole antibodies affixed to a solid support to form a reaction mixture; (b) incubating said reaction mixture for a period of time sufficient to form an antibody-skatole complex with any skatole present in said reaction mixture; (c) washing said solid support; and (d) determining the amount of said label bound to said solid support in comparison to a sample having a known amount of skatole as an indication of boar taint in said pig. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for detecting boar taint in a pig comprising:
-
(a) combining in a reaction buffer a conjugate of an enzyme with skatole or a skatole analogue, a blood sample from said pig, and anti-skatole antibodies affixed to a solid support to form a first reaction mixture; (b) incubating said first reaction mixture for a time period sufficient to form an antibody-skatole complex; (c) washing said solid support with a wash buffer; (d) incubating a solution containing a substrate for said enzyme with said solid support to form a second reaction mixture; and (e) determining the optical density of said second reaction mixture in comparison to the optical density of sample having a known amount of skatole as an indication of boar taint in said pig.

16. A method for detecting boar taint in a pig comprising:
-
(a) combining a blood sample from said pig, indole-3-butyric acid/alkaline phosphatase conjugate in Tris-buffered saline, and anti-skatole antibodies affixed to a microtiter plate to form a first reaction mixture; (b) incubating said reaction mixture at about 4°
C. for about four hours;(c) washing said microtiter plate with salinepolyoxylenesorbitan buffer; (d) incubating a p-nitrophenylphosphate solution with said microtiter plate at about 37°
C. for about one hour to form a second reaction mixture;(e) altering the pH of said second reaction mixture to stop enzyme activity to form a third reaction mixture; and (f) determining the optical density of said third reaction mixture in comparison to the optical density of a sample having a known amount of skatole to determine the skatole concentration of said sample, wherein said pig is identified as having boar said sample has greater than about 0.3 ppm skatole. - View Dependent Claims (17)
