Putative quantitative trait loci associated with the probability of contracting infectious bovine keratoconjunctivitis.

摘要: Infectious bovine keratoconjunctivitis, also known as pinkeye, is an economically important disease in cattle. The objective of this study was to detect QTL associated with infectious keratoconjunctivitis offspring from a Brahman x Hereford sire. sire mated Hereford, Angus, and F1 cows produce 288 1994 MARC III ([fraction one-quarter] [fraction Red Poll, Pinzgauer) 1996 259 (547 animals total). diagnosed by physical examination 36 the family. Records included unilateral bilateral frequency, but not severity. were binary: 0 for unaffected 1 affected A putative identified on chromosome 1, maximum F-statistic (F = 10.15; P 0.0015) at centimorgan 79 linkage group. support interval spanned centimorgans 66 110.
