Enzymes which are biological catalyst composed of amino acids with minerals and vitamins. The use of enzymes has many benefits in poultry diets include not only enhanced feed conversion and bird performance but also reduced output of excreta problems of environment. The present research work was conducted to evaluate the effect of phytase enzyme on growth performance and blood profile of broiler. Birds were arbitrarily separated into four groups, i.e. Group A (control) was offered 0 g/kg, 0.05 g/kg (group B), 0.075 g/kg (group C) and 0.025 g/kg (group D) phytase enzyme provided in broiler feed. Parameters which were selected in present research work as, feed intake, live body weight, feed conversion ratio, growth performance and blood profile. Results showed that the maximum chicken body weight was noted in group C and feed intake was minimum in group C, as compared to other groups. Feed conversion ratio was significantly (p < 0.05) higher in group C, followed by other groups the non-significantly variance founded respectively, the highest weight of liver, gizzard, heart, intestine were noted in treated group C comparatively, highest spleen weight was in group B and in group A (control) the minimum weight of spleen was noted and the average blood profile of broiler chicks in different groups, the white blood cells was significantly higher in group D followed by group A, group B and C. Red blood cells was significantly (P < 0.05) better in group C. Haemoglobin was significant differences in different groups of trial. A significant (P < 0.05) difference in Packed cells volume in group A followed by group B, C and D. Total protein in group A was minimum followed by group B, C and D, respectively. From the present study, it was concluded that supplementation of 0.075 g/kg phytase enzyme has a better effect on growth performance and blood profile of broiler.

亚临床坏死性肠炎(SNE)广泛存在于肉鸡中,通过降低生长性能来引起严重的经济和社会问题。本研究基于约氏乳杆菌BS15的分子调控机制,以及其对SNE感染肉鸡的肝脏炎症通路的影响,探讨SNE对肝脏炎症的分子机制,并研究约氏乳杆菌BS15对SNE的预防作用。将180只(Cobb 500)肉鸡分成3组,提供饮食如下:第1组作为正常对照(NC)饲喂基础日粮,第2组作为SNE对照(SNE实验模型)饲喂基础日粮+1×106 cfu LJ/g饲料,饲喂基础日粮3组,饲喂LJ(预防组+SNE实验模型),肉鸡饲养28天。收集肝脏样品用于组织学观察以比较不同处理之间的肝脏组织炎症。从肝脏样品中提取RNA,进行RNA测序以分析,并在定量实时PCR(q RT-PCR)的辅助下检测相关差异基因的表达。RNA-Seq分析显示参与肝脏炎症途径的基因表达改变。与对照肝脏样品相比,在SNE组的肝脏样品中发现总共385个基因差异表达(DEG)(p<0.05)。在这385个基因中,有117个基因表达下调,268个基因表达上调。DEGs与对照组和SNE组或SNE和BS15组之间的肝脏炎症有关,包括分化簇80(CD80),白细胞介素1β(IL1B),磷酸肌醇3-激酶调节亚基5(PIK3R5),Toll样受体4(TLR4),Toll样受体2A(TLR2A)和原癌基因蛋白(FOS)。RNA-Seq分析提供DEGs表达,该结果通过q RT-PCR验证。结果证实,这些基因在SNE感染肉鸡的肝脏炎症调节中是必需的。本研究的结果表明,SNE可能诱导肉鸡肝脏发生炎症变化,且SNE感染对肝脏的影响可以通过改进的TLRs信号传导途径以及作为约氏乳杆菌BS15的天然存在的预防策略而缓解。

引言随着抗生素的禁用,坏死性肠炎(Necrotic Enteritis,NE),尤其是亚临床型NE(Subclinical NE,SNE)开始成为威胁禽类生产的最大杀手之一。益生菌是最重要的抗生素替代物之一。不过,由于肠道的复杂性,彻底揭示益生菌的详细作用机制具有很高的难度。因此对一株益生菌进行深入研究十分有意义。基于前期研究,约氏乳杆菌BS15(Lactobacillus johnsonii BS15)体现出了较为
