Analysis of carcass performance and meat quality of Saba pigs with different genders
摘要
Abstract
This experiment aimed to evaluate the effects of sex on carcass traits and meat quality in Saba pigs.A total of 20 Saba pigs(10 males and 10 females)with an initial body weight of approximately 20 kg were raised to 320 days of age.When the average body weight reached(101.50±7.93)kg,the pigs were slaughtered to evaluate their carcass traits and meat quality.Longissimus dorsi muscle samples were collected to systematically investigate sex-related differences in amino acid profiles and fatty acid composition in the pigs.The results showed that the boars had a significantly higher skin weight percentage and larger eye muscle area than the sows(P<0.05).However,no significant differences were found in their lean meat percentage,marbling and meat color scores.The amino acid analysis showed that glutam-ic acid(Glu)had the highest taste activity value(TAV),identifying itself as the primary umami substance.The TAV of acidic amino acids was the highest(153.34 for boars and 162.41 for sows).Essential amino acids accounted for over 40％of the total amino acids(41.46％for boars and 40.45％for sows).The amino acid score(SRC)meets the FAO/WHO criteria for a high-quality protein,with values close to the reference pattern(boar:73.21;sow:72.34).Regarding fatty acids,unsaturated fatty acids accounted for a high proportion(82.959％for boars and 79.872％for sows),and bothω-3andω-6polyunsaturated fatty acids were detected.In conclusion,sex significantly influenced the amino acid composition and flavor characteristics of Saba pigs,with sows exhibiting more pronounced amino acid flavor profiles.This find-ing may serve as theoretical support for research on differences in carcass performance and meat quality between male and female Saba pigs.关键词
