title: Effect of the halothane genotype on intramuscular fat deposition in swine.
abstract: Intramuscular fat (IMF) content has been identified as an important factor in determining the quality of pork. Previous studies have suggested that IMF deposition may be associated with the presence of the halothane (HAL) gene. This study aimed to evaluate the effect of the HAL gene on IMF deposition in crossbred pigs of commercial lines, which were killed at a slaughterhouse under official inspection. The genotype of the HAL gene was determined by polymerase chain reaction-restriction fragment length polymorphism analysis. IMF was analyzed from longissimus dorsi samples. Among all animals analyzed, 42.36% were of the HalNN genotype and 57.64% were of the HalNn genotype. The average IMF content of all samples was 2.14%. Variation in IMF between genotypes was evaluated by analysis of variance. No significant difference in IMF deposition, which could be based on the presence of the halothane allele, was observed, at least in heterozygotes.
