【摘要】:本試驗旨在研究不同干燥工藝加工的苜蓿粗多糖對蛋雞生產(chǎn)性能、蛋品質(zhì)、器官指數(shù)和血清、雞蛋中抗體含量的影響。選取54只38周齡的京紅1號產(chǎn)蛋雞,隨機分為3組,每組18個重復,每個重復1只雞,單籠飼養(yǎng)。對照組飼喂玉米-豆粕型基礎(chǔ)飼糧,試驗組分別飼喂在基礎(chǔ)飼糧中添加1 000 mg/kg微波真空干燥所得苜蓿粗多糖1(ACPS1)和減壓烘干干燥所得苜蓿粗多糖2(ACPS2)。試驗期65 d。結(jié)果表明:與對照組相比,1)在試驗第28~36天,ACPS1組蛋雞的平均日采食量顯著增加(P0.05);飼糧中添加不同干燥工藝加工的苜蓿粗多糖對蛋雞各階段的產(chǎn)蛋率和平均日增重均無顯著影響(P0.05)。2)試驗第63天,ACPS1組蛋雞的蛋黃顏色顯著增加(P0.05);試驗第30天,飼糧中添加不同干燥工藝加工的苜蓿粗多糖對蛋雞的蛋殼顏色、蛋黃顏色、蛋白高度和哈氏單位均無顯著影響(P0.05)。3)ACPS1組蛋雞的肝臟指數(shù)顯著增加(P0.05),ACPS2組的卵巢指數(shù)顯著降低(P0.05);且ACPS1組的肝臟指數(shù)和卵巢指數(shù)均顯著高于ACPS2組(P0.05)。飼糧中添加不同干燥工藝加工的苜蓿粗多糖對蛋雞的脾臟指數(shù)和輸卵管指數(shù)均無顯著影響(P0.05)。4)ACPS1組蛋雞血清中免疫球蛋白Y(Ig Y)含量顯著增加(P0.05),ACPS1和ACPS2組血清中新城疫抗體(NDV-Ab)、蛋黃中NDV-Ab、蛋清中免疫球蛋白A(Ig A)和免疫球蛋白M(Ig M)含量均顯著增加(P0.05);且ACPS1組蛋黃中NDV-Ab、蛋清中Ig A和Ig M含量均顯著高于ACPS2組(P0.05)。以上結(jié)果表明,飼糧中添加苜蓿粗多糖能加深蛋雞的蛋黃顏色,增加血清和雞蛋中的抗體含量,且ACPS1的效果更佳。
[Abstract]:The purpose of this study was to study the effects of crude polysaccharide of Medicago sativa processed by different drying processes on the performance, egg quality, organ index and antibody content in serum and eggs of laying hens. Fifty-four 38-week-old Jinghong 1 laying hens were randomly divided into 3 groups with 18 repeats in each group and 1 chicken in a single cage. The control group was fed with corn-soybean meal basal diet, and the experimental group was fed with 1 000 mg/kg microwave vacuum dried crude polysaccharide 1 (ACPS1) and vacuum drying crude polysaccharide 2 (ACPS2) respectively. The experimental period is 65 d. The results showed that: 1) on the 28th to 36th day of the experiment, the average daily feed intake of laying hens in ACPS1 group increased significantly (P 0.05). Adding crude polysaccharide from different drying processes to diet had no significant effect on laying rate and average daily gain of laying hens (P 0.05). 2) on the 63rd day of experiment, the yolk color of laying hens in ACPS1 group increased significantly (P 0.05). On the 30th day of the experiment, the eggshell color and yolk color of laying hens were treated with crude polysaccharides from different drying processes. There was no significant difference in protein height and Hasteurelli unit (P0.05). 3) the liver index in ACPS1 group was significantly increased (P0.05), while the ovarian index in ACPS2 group was significantly decreased (P0.05). The liver index and ovarian index in ACPS1 group were significantly higher than those in ACPS2 group (P 0.05). There was no significant effect on spleen index and oviduct index of laying hens (P0.05). 4) the content of immunoglobulin Y (Ig Y) in serum of laying hens in ACPS1 group was significantly increased (P0.05), and there was no significant difference in spleen index and oviduct index of laying hens by adding crude alfalfa polysaccharides processed by different drying techniques (P0.05). In ACPS1 and ACPS2 groups, the contents of Newcastle disease antibody (NDV-Ab), immunoglobulin A (Ig A) and immunoglobulin M (Ig M) in NDV-Ab, egg white in egg yolk were significantly increased (P 0.05), and the contents of immunoglobulin A (Ig A) and immunoglobulin M (Ig M) in egg yolk were significantly increased (P 0.05). The contents of Ig A and Ig M in NDV-Ab, egg white in ACPS1 group were significantly higher than those in ACPS2 group (P 0.05). The above results showed that adding crude polysaccharide to diet could deepen the yolk color of laying hens and increase the antibody content in serum and eggs, and the effect of ACPS1 was better.
