【摘要】：本實(shí)驗(yàn)在基礎(chǔ)日糧中添加木聚糖酶(X1200)與小刺猴頭發(fā)酵浸膏多糖(HFP),進(jìn)行42天肉仔雞喂養(yǎng)實(shí)驗(yàn),于實(shí)驗(yàn)第21日與第42日采樣,測(cè)定肉仔雞生長(zhǎng)性能(平均體重、料重比、屠宰性能、食糜黏度)、肌肉品質(zhì)(pH、嫩度、色度、水分、系水力、血液指標(biāo))、免疫及抗氧化功能(免疫器官指數(shù)、血液因子)指標(biāo),比較木聚糖酶與小刺猴頭發(fā)酵浸膏多糖復(fù)合飼料添加劑與抗生素在肉仔雞生產(chǎn)中的應(yīng)用效果,研究木聚糖酶與小刺猴頭發(fā)酵浸膏多糖作為替代抗生素飼料添加劑對(duì)肉仔雞飼養(yǎng)的影響,旨在獲得一種既能提高肉仔雞生產(chǎn)性能,又能替代抗生素的安全、綠色復(fù)合飼料添加劑。1.通過對(duì)木聚糖酶與小刺猴頭發(fā)酵浸膏多糖復(fù)合飼料添加劑替代抗生素對(duì)肉仔雞生長(zhǎng)性能的影響研究顯示:在整個(gè)實(shí)驗(yàn)期,X1200+HFP組肉仔雞平均體重顯著高于對(duì)照(CK)組(P0.05);胸肌率與腿肌率均顯著高于CK組(P0.05);腸道食糜黏度顯著低于CK組(P0.05)。在實(shí)驗(yàn)期1-21日齡和22-42日齡,與CK組相比較,X1200+HFP組肉仔雞平均體重分別提高0.89%與10.29%,料重比分別降低3.76%與9.54%,其腹脂率無(wú)顯著性差異(P0.05)。2.通過對(duì)木聚糖酶與小刺猴頭發(fā)酵浸膏多糖復(fù)合飼料添加劑替代抗生素對(duì)肉仔雞肌肉品質(zhì)的影響研究顯示:在整個(gè)實(shí)驗(yàn)期,X1200+HFP組肉仔雞肌肉水分顯著高于CK組(P0.05);色度L值顯著高于CK組(P0.05);48h滴水損失顯著低于CK組(P0.05);膽固醇及甘油三酯含量顯著低于CK組(P0.05)。木聚糖酶與小刺猴頭多糖復(fù)合飼料添加劑有顯著改善肉仔雞肌肉系水能力、肌肉水分、膽固醇及甘油三酯含量的功效(P0.05),對(duì)肉仔雞肌肉嫩度、色度及pH有一定改善作用但效果不明顯(P0.05)。3.通過對(duì)木聚糖酶與小刺猴頭發(fā)酵浸膏多糖復(fù)合飼料添加劑替代抗生素對(duì)肉仔雞免疫及抗氧化功能的影響研究顯示:X1200+HFP組肉仔雞肌免疫器官指數(shù)均顯著高于CK組(P0.05),肉仔雞血清中IL-2、IFN-γ、T-SOD、CAT和MDA含量與抗生素影響結(jié)果基本一致,無(wú)顯著性差異(P0.05)。在肉雞生產(chǎn)中使用木聚糖酶與小刺猴頭發(fā)酵浸膏多糖復(fù)合飼料添加劑替代抗生素,復(fù)合飼料添加劑可有效提高肉仔雞生長(zhǎng)性能,在一定程度上改善肉仔雞肌肉品質(zhì),顯著提高肉仔雞免疫器官指數(shù),可起到替代抗生素在肉仔雞免疫及抗氧化功能中發(fā)揮作用。
[Abstract]:In this experiment, we added xylanase (X1200) and yeast extract polysaccharide (HFP) in the basal diet for 42 days of broiler feeding experiment. The growth performance (average weight, material weight ratio, slaughter performance, chying viscosity) and muscle quality (pH, tenderness, color, moisture, water, hydraulic, blood index) were measured on the twenty-first day and forty-second day of the experiment. Immune and antioxidant function (immune organ index, blood factor) index, compare the application effect of xylanase and polysaccharide compound feed additive and antibiotic in the production of broiler, and study the effect of xylanase and little monkey hair leaven extract polysaccharide as substitute antibiotic feed additive on broiler breeding The effect of green compound feed additive.1. on the growth performance of broilers was studied. The study showed that the average body of broilers in group X1200+HFP was in the whole period of the experiment. The effect of green compound feed additive on the growth performance of broilers was studied. Significantly higher than the control group (CK) group (P0.05), the breast muscle rate and the leg muscle rate were significantly higher than that of the CK group (P0.05), and the viscosity of intestinal chic was significantly lower than that of the CK group (P0.05). At 1-21 days of age and 22-42 days of age in the experimental period, the average weight of the broilers in the X1200+HFP group increased by 0.89% and 10.29%, and the weight ratio decreased by 3.76% and 9.54% respectively, and the abdominal fat rate was not significant. The effect of P0.05.2. on the muscle quality of Broilers by the combination of xylanase and little monkey hair leaven compound feed additive to the muscle quality of broilers showed that the muscle moisture of the broilers in the X1200+HFP group was significantly higher than that of the CK group (P0.05) in the whole experimental period, and the L value of the chroma was significantly higher than that of the CK group (P0.05), and the loss of 48h dripping water was significantly lower than that of the CK group. (P0.05); the content of cholesterol and triglyceride was significantly lower than that of group CK (P0.05). The compound feed additive of xylanase and spick Hericium polysaccharide could significantly improve the water ability, muscle moisture, cholesterol and triglyceride content of broiler (P0.05), and had a certain effect on meat tenderness, chroma and pH of broiler, but the effect was not obvious (P0. 05) through the study of the effect of.3. on the immune and antioxidant function of broilers, the study showed that the immune organ index of the X1200+HFP group was significantly higher than that of the CK group (P0.05), and the content of IL-2, IFN- gamma, T-SOD, CAT and MDA in Broiler Serum and the effect of antibiotics Basically, there is no significant difference (P0.05). In the production of broiler, the use of xylanase and the compound feed additive of little monkey hair leaven extract to replace antibiotics, the compound feed additive can effectively improve the growth performance of broilers, improve meat quality of broilers to a certain extent, and significantly improve the immune organ index of broilers. Instead of antibiotics, it plays a role in immune and antioxidant functions of broilers.
