摘要： 研究了在基础日粮中短期添加不同水平的硫酸镁对杂种野猪肉品质的影响。试验分成4个处理，每个处理2个重复，每个重复3头猪。试验进行5d，处理组镁（硫酸镁）的添加水平分别为0、1000、2000和3000mg/kg。结果表明，在屠宰前5天饲粮添加2000mg/kg、3000mg/kg硫酸镁显著提高了杂种野猪肉的品质，显著提高了猪肉的初始pH（pH1）和肉色评分（p<0.05），分别比对照组提高5.92%、5.10%和17.77％、16.94％；显著降低了滴水损失（p<0.05），比对照组分别降低了13.13％和17.90%。此外，2000mg/kg组血清镁和肌肉镁含量比对照组分别提高了26.15%和13.81%；3000mg/kg组血清镁和肌肉镁含量比对照组分别提高了30.77%和15.98%。

Abstract: To study the effect of magnesium sulphate supplementation in the basal diet for 5 day prior to slaughter on meat quality of pigs, seventy-two crossbred wild pigs weighing 90kg were randomly allotted into 4 groups, Each group contained 2 replicates with 3 pigs per replicate, The levels of magnesium sulphate supplementation were 0, 1000, 2000 and 3000 mg/kg of Mg contents. The results showed supplementation of 2000mg/kg、3000mg/kg magnesium sulphate significantly improved pH1 and meat color score（p<0.05）by 5.92%、5.10% and 17.77%、16.94% separately. At the same time, it also significantly decreased drip loss by 13.13％ and 17.90%（p<0.05）.2000mg/kg magnesium sulphate significantly improved contents of Mg in serum and muscle by 26.15% and 13.81% .3000mg/kg magnesium sulphate also significantly improved contents of Mg in serum and muscle by 30.77% and 15.98% separately.
