摘要： 为探索散养和圈养养殖模式对淮南猪屠宰和肉质性状的影响，选择发育正常、出生体质量相似的淮南仔猪20头，随机分为散养组和圈养组。在供试猪只体质量达100 kg左右时，每组随机选择5头猪进行屠宰试验，测定屠宰性状、肉质性状以及背最长肌氨基酸、脂肪、维生素、矿物元素含量。结果显示，与圈养组相比，散养组背膘厚（三点均值）和肌内脂肪含量分别降低33.74%（P<0.05）和53.25%（P<0.05），单个肾质量升高18.85%（P<0.05），散养组眼肌面积和后腿比例分别提高2.45%和23.37%，但滴水损失降低45.83%。散养组鲜味氨基酸含量更高，而圈养组必需氨基酸含量更高。散养组维生素B1含量
比圈养组高24.24%(P<0.05)。散养组钙和钾含量分别比圈养组高44.94%（P<0.05）和5.54%（P>0.05）。综上所述，散养模式显著减少脂肪沉积，提高眼肌面积和后腿比例，同时散养模式可促进维生素B1、钙、钾和鲜味氨基酸的沉积，提高鲜味和嫩度，有助于提高淮南猪肉质性状。

Abstract: To explore the influence of free‑range and captivity feeding styles on slaughter and meat quality of Huainan pigs，twenty well‑developed Huainan pigs with similar birth weight were randomly selected，and divided into two groups，free‑range group and captivity group. Five pigs were randomly selected in each group for slaughtering test when their body weight achieved around 100 kg. Slaughter traits，meat quality traits，the content of amino acid，fat，vitamin and mineral elements in longissimus dorsi（LD）muscle were compared between these two groups. The results indicated that compared with the
captivity group，the backfat thickness and intramuscular fat content were reduced by 33. 74%（P<0. 05）and 53. 25%（P<0. 05）in free‑range group，respectively. But single kidney weight was increased by 18. 85% in free‑range group compared to captivity group（P<0. 05）. Compared with captivity group，the eye muscle area and ham percentage in the free‑range group were increased by 2. 45% and 23. 37%，respectively. Drip loss in free‑range group was 45. 83% lower than that of captivity group. The content of umami amino acid was higher in free‑range group，but the content of essential amino acid was higher in
captivity group. In free‑range group，the content of vitamin B1 was 24. 24%（P<0. 05）higher than that in captivity group. The calcium and potassium contents in free‑range group were 44. 94%（P<0. 05）and 5. 54%（P>0. 05）higher than those in captivity group，respectively. In summary，the free‑range feeding style significantly reduced fat deposition，increased the eye muscle area and hind leg ratio，promoted the deposition of vitamin B1，calcium，potassium，and umami amino acid，and improved umami taste and tenderness. The free‑range breeding style could improve the meat quality traits of Huainan pigs.
