Abstract:
Three hundred and one piglets of Suzh ong line 1 and 2 were chosen for halothane test(HT), with the halothane positive rate of 1.33%. 34 halothane negative(HN) piglets were randomly selected for gen otype testing and 6 of them were found to be heterozygous. The results showed th at genotype frequencies of HalNN, HalNnand Halnn w ere 81.26 %, 17.4% and 1.33%, respectively, while the frequencies of N gene and n gene wer e 89.97% and 10.03%, separately. 4 pigs with genotype Halnn gave worst meat quality appearing 3 typical and 1 slight PSE meat. Pigs with genotype Hal N Nor HalNndid not show PSE meat. 208 offspring from 20 HN sows mat ed wit h halothane positive(HP) boars, 21 piglets from 4 litters were HP, with low dail y gain, low feed efficiency and bad meat quality but high dressing percentage, l arge loin-eye area and high lean meat percentage.
