Abstract

Forty-two (42) finishing pigs (entire males—EM, surgical castrates—SC and gilts—G, each of 14)—progeny of Landrace sows and Hampshire × Pietrain boars, were included in the trial. They were randomly divided into control and experimental groups (each of seven). Control groups were fed the standard diet without any supplement. Experimental groups received standard diet with the same composition as control but with supplement of creatine monohydrate (CMH, 2.0 g/kg of feed) for 30 d prior to slaughter. Sex of pigs had significant effect (p < 0.05) on drip loss and tenderness of pork when EM showed higher drip loss than SC and lower tenderness compared to other two groups (4.71% vs. 3.80%, resp. 3.23 vs. 3.91 and 4.12). Creatine level in plasma was increased by CMH supplementation in 46% in EM, 43% in SC and 41% in G. Similarly, concentration of phosphocreatine (PCr) in muscle increased in 84% in EM, 88% in SC and 83% in G, respectively. CMH also improved meat colour L (50.03 vs. 48.88) and reduced drip loss in both EM (5.24% vs. 4.18%) and G (4.48% vs. 3.60%). Higher tenderness and better oxidative stability of pork after CMH supplementation was found in all three sexes.
一水肌酸日粮对母猪、全猪和去势公猪肌肉代谢、品质、感官和氧化稳定性的影响
试验包括42头长白母猪和汉普郡×皮特列公猪的后代育肥猪(公全猪- em,手术阉割猪- sc和后备猪- g,每14头)。他们被随机分为对照组和实验组(每组7人)。对照组饲喂标准日粮,不添加任何添加剂。试验组宰前30 d饲喂标准饲粮,其组成与对照组相同,但在饲料中添加一水肌酸(CMH, 2.0 g/kg)。猪的性别对猪的滴漏损失和嫩度有显著影响(p < 0.05), EM组的滴漏损失高于SC组,嫩度低于其他两组(分别为4.71%和3.80%)。3.23 vs. 3.91和4.12)。添加CMH后,EM组、SC组和G组的血浆肌酸水平分别升高46%、43%和41%,肌肉中磷酸肌酸(PCr)浓度分别升高84%、88%和83%。CMH还改善了肉色L(50.03比48.88),降低了EM(5.24%比4.18%)和G(4.48%比3.60%)的滴漏损失。在三种性别中,添加CMH后猪肉的嫩度更高,氧化稳定性更好。
