| 摘 要： | 选用体重相近的氟烷基因杂合子(HalNHaln)大长猪(大白猪×长白猪)36头随机分为两组,即对照组、乙酸镁组,每组18头。乙酸镁组试猪在屠宰前5 d基础饲粮中添加1 500 mg/kg镁(以乙酸镁形式),对照组饲喂基础日粮,研究屠宰前饲粮中短期添加镁对氟烷基因杂合子猪肉质改善效果。结果表明,在猪屠宰前饲粮中短期添加1 500 mg/kg镁对试验猪的平均日采食量没有明显影响(P>0.05);可以提高肌肉起始pH值,同时还具有降低肌肉的滴水损失的作用(P<0.05)。 |

| Abstract: | To study the effects of short term dietary addition of Mg prior to slaughter on meat quality,total of 36 HalNHaln pigs(Y×L) with similar initial live weight were equally divided into two groups for further investigation.For the Magnesium acetate group,the diet was added 1 500 mg/kg Mg in form of Magnesium acetate.The results showed that the dietary addition of Mg had no significantly effects on ADFI of pigs(P>0.05) while short term addition of 1 500 mg/kg Mg prior to slaughter enhanced the muscle initial pH.Simultaneously,Mg addition could lower the muscle dropping lose(P<0.05). |
| Keywords: | Pig Halothane gene Magnesium acetate pH Drip loss |
