Comparison of PRKAG3 and RYR1 gene effect on carcass traits and meat quality in Slovenian commercial pigs
PRKAG3 RYR1 genotype frequencies carcass properties meat quality gene interaction
2015/6/8
The effect of polymorphisms at PRKAG3 (R200Q and I199V) and RYR1 (R615C) genes on carcass traits and meat quality was examined in a sample of 257 commercial pigs, crosses of Landrace × Large White as ...
旨在研究二甲双胍(Metformin)对PRKAG3基因表达量以及对猪生长性能及肉质的影响。挑选80 kg左右的杜洛克×长白×大约克三元杂交(DLY)阉公猪10头，随机分为对照组和试验组。试验组日粮中添加400 mg·kg-1体质量的Metformin，对照组日粮除不含Metformin外，其它日粮成分与试验组相同。2周试验结束后所有猪只全部屠宰，测定生长性能、AMPK活性、PRKAG3基因表达量...
本研究以晋南牛、鲁西牛、西门塔尔、安格斯、海福特、利木赞和夏洛莱7个品种共267头肉牛为试验材料，采用PCRRFLP技术检测PRKAG3基因多态性，找到了PRKAG3基因DNA序列中的 2个突变位点T2643C和T2885C(DQ082736)，同属第4内含子。2个基因多态性位点与肉牛胴体和肉质共9个性状的关联分析表明：PRKAG3基因T2885C变异位点的3个基因型间嫩度性状差异显著（P＜0...
挑选70 kg左右的DLY猪12头，随机分为2组，分别饲喂高、低2种水平的日粮，高营养水平为DE 13.81 MJ/kg、CP 14%，低营养水平为DE 12.55 MJ/kg、CP 11%。体重达到100 kg左右时屠宰，测定胴体性状、肉质性状和PRKAG3基因表达量。以探讨营养水平对PRKAG3基因表达量及肉质的影响。结果表明：低营养水平有促进PRKAG3基因表达的趋势(P>0.05)；高营养...
0.05）。但滴水损失显著低于低营养水平(P0.05）；与pH2呈显著负相关(P<0.05)。这表明营养水平对PRKAG3基因表达量有一定的影响，进而可影响肉质。
New Evidence of Alleles (V199I and G52S) at the PRKAG3 (RN) Locus Affecting Pork Meat Quality
