【摘要】：為研究飼糧添加單月桂酸甘油酯(GML)對(duì)蛋雞生產(chǎn)性能、蛋品質(zhì)、血清生化指標(biāo)、免疫器官指數(shù)和腹脂形態(tài)的影響,以44周齡海蘭褐蛋雞為研究對(duì)象,在飼糧中添加150、300和450 mg/kg GML飼喂8周后分析蛋雞相關(guān)指標(biāo)的變化。結(jié)果表明,與對(duì)照組相比,飼糧添加300和450 mg/kg GML可以提高蛋雞產(chǎn)蛋率、血清中超氧化物歧化酶和谷胱甘肽過氧化物酶的活力(P0.05),同時(shí)顯著降低血清中丙氨酸氨基轉(zhuǎn)移酶的活力,丙二醛、總膽固醇、低密度脂蛋白膽固醇和總膽紅素的含量以及腹脂率(P0.05)。飼糧添加300 mg/kg GML可以顯著提高雞蛋蛋白高度、哈氏單位和蛋黃顏色(P0.05)。飼糧添加450 mg/kg GML還可以顯著提高血清中總蛋白和高密度脂蛋白膽固醇的含量(P0.05),同時(shí)顯著降低蛋雞血清中天門冬氨酸氨基轉(zhuǎn)移酶活力(P0.05)。此外,飼糧添加GML可以顯著降低蛋雞料蛋比和血清中甘油三酯的含量以及脂肪細(xì)胞的平均面積、平均周長(zhǎng)和平均體積(P0.05),顯著提高蛋雞單個(gè)蛋重、脾臟指數(shù)和胸腺指數(shù)(P0.05)�？傮w來看,飼喂GML對(duì)提高蛋雞生產(chǎn)性能、蛋品質(zhì)、抗氧化能力和免疫功能,改善蛋雞脂肪代謝和健康狀況具有積極的作用。
[Abstract]:In order to study the effects of dietary supplementation of glycerol monolaurate (GML) on performance, egg quality, serum biochemical index, immune organ index and abdominal fat morphology of laying hens, the 44-week-old Hailan brown laying hens were studied. The changes of relative indexes of laying hens were analyzed after feeding for 8 weeks with 150300 and 450 mg/kg GML in diet. The results showed that compared with the control group, dietary supplementation of 300 and 450 mg/kg GML could increase laying rate, increase the activity of superoxide dismutase (SOD) and glutathione peroxidase (Glutathione peroxidase) in serum and decrease the activity of serum alanine aminotransferase (alt). The contents of malondialdehyde (MDA), total cholesterol (TC), low density lipoprotein cholesterol (LDL-C) and total bilirubin (Tbilirubin), and the abdominal fat rate (P0.05@@ The egg protein height was significantly increased by adding 300 mg/kg GML to the diet. The contents of serum total protein and high density lipoprotein cholesterol (HDL-C) and aspartate aminotransferase (AST) activity in laying hens were significantly decreased by adding 450 mg/kg GML to diet. In addition, diet supplemented with GML could significantly decrease the feed to egg ratio, triglyceride content in serum, average area of fat cells, average circumference and average volume of P0.05, and significantly increase the weight of single egg, spleen index and thymus index of laying hens. In general, feeding GML can improve the performance, egg quality, antioxidant ability and immune function of laying hens, and improve the fat metabolism and health status of laying hens.
