为研究不同营养水平对长白×沙子岭二元杂种猪肉理化指标的影响，选择体重25 kg左右的长×沙二元杂种猪60头，随机分成3组，分别饲喂高、中、低3种不同营养水平饲粮，每组2个重复，每个重复10头猪饲养在同一栏内，进行为期122 d的饲养试验。饲养试验结束后每组屠宰4头猪测定猪肉理化指标。结果表明，肌内脂肪含量，低水平组、中水平组分别比高水平组高1.08个百分点、0.74个百分点，差异显著（P<0.05）。硬脂酸含量，高水平组和中水平组分别比低水平组高2.80个百分点和2.38个百分点，差异显著（P<0.05）；肉豆蔻酸、月桂酸含量，高水平组分别比中、低水平组高0.69个百分点和0.75个百分点、0.05个百分点和0.04个百分点，差异显著（P<0.05）；饱和脂肪酸含量，高水平组和中水平组分别比低水平组高3.66个百分点和2.75个百分点，差异显著（P<0.05）。高、中水平组鲜味氨基酸、必需氨基酸及总氨基酸含量高于低水平组，但差异不显著（P>0.05）；粗蛋白质、水分、粗灰分及矿物元素的含量，3组差异不显著（P>0.05）；3组均未检测出砷、氟，铅含量都在安全范围内。

For study the effects of different nutrition levels of diets on pork physicochemical indexs of Large white×Shaziling pig,sixty Large white×Shaziling pigs with body weight of about 25 kg were randomly divided into three experimental groups,with two reputations in each group and 10 pigs (fed in the same coop) in each reputa-tion,and fed with high,medium,and low nutrition levels of diets respectively for 122 days.Then,4 pigs in each group was slaughtered for determining pork physicochemical indexs.The results showed that intramuscular fat content of low and medium nutrition levels were higher than high nutrition level with 1.08 and 0.74 percent,re-spectivly (P<0.05).Stearic acid content of high and medium nutrition levels were higher than low nutrition level with 2.80 and 2.38 percent,respectivly(P<0.05).The content of Lauric acid and myristic acid of high nutrition level were respectivly higher than low and medium nutrition levels with 0.69 and 0.75 percent,0.05 and 0.04 percent (P<0.05).Saturated fatty acid content of high and medium nutrition levels were higher than low nutrition level with 3.66 and 2.75 percent,respectivly(P<0.05).But there were no differences between each groups,including the con-tent of flavor amino acid,essential amino acid,total amino acid,crude protein,crude ash,mineral elements and water content.As and F were not checked in three groups,as well as the content of Pb is limited in the safe dose.
