Immunization of pigs against gonadotrophinreleasing factor (GnRF) prevents boar taint andaffects boar growth and behaviour
Peri– and post–pubertal boars accumulate substances in their fatty tissue, predominantly androstenone and skatole, that are responsible for boar taint in pork. One method of inhibiting sexual development, reducing plasma gonadotrophin and testosterone and reducing the accumulation of these substances in carcass fat, is immunization against gonadotrophin releasing factor (GnRF). Recently, a vacc...
متن کاملBreed differences in boar taint: relationship between tissue levels boar taint compounds and sensory analysis of taint.
A total of 228 intact male pigs form Duroc, Hampshire, Landrace, and Yorkshire breeds were used in the experiment. Samples of salivary gland and backfat were collected at slaughter for colorimetric assay of salivary and fat 16-androstene levels and fat skatole levels. Fat levels also were tested by a sensory panel using an R-index technique for detecting the presence of boar taint. The proporti...
متن کاملEvaluation of various boar taint detection methods.
The aim of this study was to evaluate the performance of various boar taint detection methods, measure the relationship between them and identify possible points of improvement for boar taint detection. The methods used to evaluate boar taint in the carcasses of 448 entire male pigs and 17 barrows were the hot iron method (n = 442), a standardised (n = 323) and home (n = 58) consumer meat-evalu...
متن کاملEffect of dietary chicory on boar taint.
Following preliminary screening and feeding trials on farms supplying a commercial abattoir, 360 entire male pigs were used to evaluate the effects of different percentages of chicory (Cichorium intybus L.) on levels of boar taint compounds and sensory aspects in backfat. Pigs were fed 0, 3, 6 or 9% chicory in the diet, 30 pigs being sampled at 3 different times: initially to measure basal leve...
متن کاملConsumer studies on sensory acceptability of boar taint: a review.
Boar taint can be found in meat from boars and affects consumer acceptability of pork. The aim of this review is: (1) to describe different aspects of the existing methodologies used in consumer studies when evaluating boar taint from a sensory point of view, (2) to draw conclusions on different studies regarding the acceptability of meat from entire males, and (3) to discuss a possible harmoni...
