【摘要】：本試驗(yàn)旨在探討博落回提取物對乳鴿生長性能、器官指數(shù)、血清生化指標(biāo)和免疫功能的影響。選取了280只體重相近、健康的10日齡乳鴿,采用單因素完全隨機(jī)試驗(yàn)設(shè)計(jì),隨機(jī)分為7個(gè)組,每組10個(gè)重復(fù),每個(gè)重復(fù)4只乳鴿,對照組(A組)飼喂基礎(chǔ)飼糧,試驗(yàn)組(B、C、D、E、F、G組)分別在基礎(chǔ)飼糧中添加30、40、50 mg/kg博落回散,40 mg/kg博落回提取物PE50,40 mg/kg博落回提取物BE60和150 mg/kg金霉素。預(yù)試期5 d,正試期15 d。結(jié)果顯示:1)各組間平均日增重和料重比均無顯著差異(P0.05)。2)各組間胸腺指數(shù)和法氏囊指數(shù)均無顯著差異(P0.05)。E組脾臟指數(shù)極顯著高于對照組(P0.01),D組顯著高于對照組(P0.05)。D組胰腺指數(shù)顯著高于對照組、B組和F組(P0.05)。3)E組血清總蛋白含量顯著高于G組(P0.05)。B組血清低密度脂蛋白含量顯著高于對照組(P0.05)。4)D組血清免疫球蛋白G含量極顯著高于對照組和B組(P0.01),顯著高于其他組(P0.05);E組血清白細(xì)胞介素-6含量顯著低于對照組(P0.05)。由此可見,博落回提取物可提高乳鴿免疫器官指數(shù)和血清中總蛋白、低密度脂蛋白、免疫球蛋白G含量,從而提高機(jī)體免疫力。
[Abstract]:The purpose of this study was to investigate the effects of extract of Fructus fulva on growth performance, organ index, serum biochemical index and immune function of pigeon. 280 10-day-old pigeons of similar weight and healthy weight were randomly divided into 7 groups with 10 replicates in each group. The control group (group A) was fed with basic diet. The basal diet was supplemented with 30m 4050 mg/kg, 40 mg/kg PE50,40 mg/kg extract, BE60 and 150 mg/kg chlortetracycline, respectively. The pre-test period was 5 days and the current test period was 15 days. The results were as follows: 1) there was no significant difference in average daily gain and feed weight ratio among groups (P0.05). 2) there was no significant difference in thymus index and bursa index between each group (P0.05). The spleen index of). E group was significantly higher than that of control group (P0.05). Radiation group (P0.01), Group D was significantly higher than control group (P0.05) pancreatic index in). D group was significantly higher than that in control group. The content of serum total protein in group B and group F (P0.05) was significantly higher than that in group G (P0.05). The content of serum low density lipoprotein (LDL) in group E was significantly higher than that in group D (P0.05). G content was significantly higher than that in control group and B group (P0.01). Significantly higher than other groups (P0.05); The level of serum IL-6 in E group was significantly lower than that in the control group (P 0.05). It can be seen that the extract can improve the immune organ index of pigeon and the contents of total protein, low density lipoprotein and immunoglobulin G in serum of pigeon.
