日粮中添加菊粉和不同脂肪类型对肉鸡行为、血清代谢物、肝脏脂肪、腹脂沉积以及组织中脂肪酸成分的影响

该试验旨在评价2种不同脂肪来源的饲料中添加菊粉对肉鸡行为、血清代谢物、肝脏脂质、腹脂、胸肌和腿肌中脂肪酸组成的影响。将240只1日龄雌性肉鸡随机分成6组,每组8个重复,每个重复5只肉鸡。试验采用3×2双因子试验设计,菊粉设3个水平(0、5和10g/kg),日粮中2种类型的脂肪[棕榈油(PO)组和葵花籽油(SO)组]含量均为90g/kg。试验期为1～34d。日粮中的脂肪不影响肉鸡的体重增长,但PO组肉鸡的消化率低于SO组(p<0.001)。日粮中含棕榈油增加了肉鸡腹脂沉积和血清中脂质及葡萄糖的含量。PO组肉鸡肝脏中的三酰甘油含量高于SO组。同样,日粮中的脂肪改变了肉鸡腹脂和肌内的脂肪酸组成,导致PO组肉鸡的C16:0和C18:1n-9含量高于SO组,C18:2n-6含量却更低。日粮中添加菊粉对肉鸡体重的增长(p=0.017)有二次效应,而对消化率没有影响。与对照组相比,菊粉减少了肉鸡肝脏油脂的总含量(p=0.003)、血清中甘油三酯含量以及低密度的脂蛋白胆固醇(31%)。菊粉添加到含葵花籽油的日粮中,增加了肉鸡腹脂和肌内多不饱和脂肪酸与饱和脂肪酸的比值。该研究结果表明:日粮中添加菊粉对肉鸡血脂的有益作用,是因为减少了三酰甘油含量。该结果同样证明,菊粉增强了葵花籽油提高肉鸡肌内多不饱和脂肪酸与饱和脂肪酸比值的能力。

Production of High Quality Functional Labneh Cheese Using Exopolysaccharides Producing Encapsulated Lactobacillus Bulgaricus

Production of polysaccharides by lactic acid bacteria is vital and its technology is very important, too in dairy study. The selection ofexpolysaccharides producing encapsulated Lactobacillus bulgaricus in alginate gel and the factors affecting the production of polysaccharides such as time, temperature, pH and the growth with Streptococcus thermophilus were studied, pH 5.5 and temperature 35℃/18hr were found to be optimal for exopolysaccharides production by encapsulated L. bulgaricus and free culture yielding 600 mg/L and 380 mg/L respectively. Co-culturing L. bulgaricus with S. thermophilus increased exopolysaccharides production at 35 ℃/18hr to 660 mg/L by encapsulated cells and 400 mg/L by free culture. Results of this study were applied in the manufacture of Labneh cheese vitally containing probiotic species ofL. acidophilus, L. gasseri, L. johnsonii and protection of these bacteria by polysaeeharide produced encapsulated L. bulgaricus. The use of exopolysaccharides producing encapsulated L. bulgaricus and probiotic bacteria can provide acceptable quality to functional Labneh. This product can be used as therapeutic and diabetic milk product with highly acceptable qualities. It is noted that all of the results are the means of triplicate experiments.
