摘要:

目的 探讨绿茶浸提液对青脚麻鸡屠宰性能、肉品质以及血清生化指标的影响。 方法 选取400只1日龄、健康且体重相近(40 g±5 g)的青脚麻鸡,随机分成4组,每组5个重复,每个重复20只鸡,公母各半。各组鸡饲喂相同基础饲粮,对照组饮用常温凉开水,试验Ⅰ、Ⅱ、Ⅲ组分别给予0.3%、0.6%和1.2%绿茶浸提液供其自由摄取,试验期42 d。试验期结束后,从每个重复中随机选取2只鸡,翅静脉采血5 mL用于血清生化指标的检测;屠宰取两侧胸肌、腿肌,分别用于屠宰性能与肉品质测定。 结果 屠宰性能结果显示,与对照组相比,各试验组青脚麻鸡屠宰率、半净膛率均显著升高(P<0.05),试验Ⅰ和Ⅱ组青脚麻鸡全净膛率均显著升高(P<0.05)。肉品质结果显示,与对照组相比,各试验组青脚麻鸡胸肌剪切力均显著降低(P<0.05),试验Ⅱ和Ⅲ组青脚麻鸡胸肌亮度(L*)值均显著降低(P<0.05),试验Ⅱ组青脚麻鸡的腿肌脂肪含量显著升高(P<0.05),试验Ⅰ组青脚麻鸡的腿肌红度(a*)值显著升高(P<0.05)。血清生化结果显示,与对照组相比,试验Ⅱ组青脚麻鸡血清总蛋白(TP)、白蛋白(ALB)、高密度脂蛋白胆固醇(HDL-C)含量均显著升高(P<0.05),血清碱性磷酸酶(ALP)活性显著降低(P<0.05);试验Ⅰ和Ⅲ组青脚麻鸡血清TP、球蛋白(GLB)含量均显著降低(P<0.05),血清ALB含量显著升高(P<0.05);试验Ⅲ组青脚麻鸡血清甘油三酯(TG)含量和ALP活性均显著降低(P<0.05)。与试验Ⅰ和Ⅲ组相比,试验Ⅱ组青脚麻鸡血清尿素氮(BUN)含量显著降低(P<0.05)。 结论 饮用绿茶浸提液可提高青脚麻鸡的屠宰性能,改善肉品质,提升腿肌脂肪沉积,并对机体蛋白质和脂类代谢具有调节作用,其中以0.6%浓度的效果最佳。

Abstract:

Objective This study aimed to investigate the effects of green tea aqueous extract on slaughter performance, meat quality, and serum biochemical indices of Cyan-shank partridge chickens. Method A total of 400 one-day-old healthy Cyan-shank partridge chicks with similar body weight (40 g±5 g) were randomly divided into four groups, with five replicates per group and 20 chicks per replicate. All chicks were fed the same basal diet. Chicks in control group received cooled boiled water at room temperature, while chicks in experimental groups Ⅰ, Ⅱ and Ⅲ were provided with 0.3%, 0.6% and 1.2% green tea aqueous extract for free intake, and the experiment period was 42 days. At the end of the experiment, two chicks from each replicate were randomly selected for blood collection from the wing vein, followed by slaughter. Bilateral breast and thigh muscles were collected to determine slaughter performance and meat quality. Result Regarding slaughter performance, compared with control group, the Cyan-shank partridge chickens in all green tea aqueous extract-treated groups showed a significant increase in slaughter rate and semi-eviscerated yield (P<0.05). Chickens in groups Ⅰ and Ⅱ also exhibited a significantly higher eviscerated yield (P<0.05). For meat quality parameters, shear force of the breast muscle was significantly decreased in all treatment groups (P<0.05). The lightness (L*) value of breast muscle was significantly reduced in groups Ⅱ and Ⅲ (P<0.05). Furthermore, the Cyan-shank partridge chickens in group Ⅱ showed a significant increase in thigh muscle crude fat content (P<0.05), while the redness (a*) value of thigh muscle in group Ⅰ was significantly increased (P<0.05). Analysis of serum biochemical indices revealed that chickens in group Ⅱ had significantly higher serum levels of total protein (TP), albumin (ALB), and high-density lipoprotein cholesterol (HDL-C) (P<0.05), along with significantly lower alkaline phosphatase (ALP) activity (P<0.05). In groups Ⅰ and Ⅲ, chickens exhibited significantly decreased serum TP and globulin (GLB) contents (P<0.05), but an increased ALB content (P<0.05). Additionally, chickens in group Ⅲ showed significantly reduced serum triglyceride (TG) content and ALP activity (P<0.05). Serum urea nitrogen (BUN) content in group Ⅱ was significantly lower than that in groups Ⅰ and Ⅲ (P<0.05). Conclusion Dietary supplementation with green tea aqueous extract improved the slaughter performance and meat quality of Cyan-shank partridge chickens, enhanced fat deposition in thigh muscle, and positively regulated protein and lipid metabolism. The most effective concentration was 0.6%.
