The trend of using probiotic, prebiotic and their mixture as alternative feed additives which works as growth promoters in poultry diets to increase the productive performance and the immunity of the flock still have an importance consideration. So that the aim of this study is to estimate the impact of Bio-plus2B® (probiotic), Techno Mos® (prebiotic) or their mixture (synbiotic) on egg production, egg and shell quality, some blood metabolites and retention of nutrients between 28 and 40 weeks of age. The hens (ISA brown laying) were allocated randomly in 40 cages; 10 cages/treatment with two hens each. The treatments were the control (T1), T2 (Probiotic: 1 g Bio-plus2B® (Bacillus licheniformis plus Bacillus subtilis)/kg feed), T3 (Prebiotic: 1 g Techno Mos® (Mannanoligosaccarides (MOS) and 1,3 B-glucan) /kg feed) and T4 (Synbiotic: 1 g Bio-plus2B® plus 1 g Techno Mos®/ kg feed).
Hen-day egg production% and mass were significantly increased (P < 0.05) with T2 and T4 treatments. The experimental treatments recorded an increase in albumen index, Haugh unit (P < 0.01), shell thickness (P < 0.05), the retention of crude protein (CP), crude fiber (CF) and ether extract (EE) (P < 0.05), plasma globulin, albumin and total protein (P < 0.001) versus to the untreated group, while egg weight was not affected. Synbiotic treatment showed a significant (P < 0.001) increase in shell calcium content. T3 and T4 treatments were significantly decreased plasma cholesterol (P < 0.001) and low density lipoprotein (LDL) (P < 0.05). Alanine transaminase (ALT) was significantly (P < 0.001) decreased and estradiol hormone was increased (P < 0.001) in the experimental groups versus to the control.
It concluded that adding probiotic and/or prebiotic in the early age laying hens diets had beneficial effects for productivity with improving the egg shell thickness.
使用益生菌、益生元及其混合物作为替代饲料添加剂的趋势,这些添加剂在禽类饲料中作为生长促进剂,以提高禽类的生产性能和免疫力,仍然是一个重要的考虑因素。因此,本研究的目的是评估 Bio-plus2B®(益生菌)、Techno Mos®(益生元)或它们的混合物(合生元)对 28 至 40 周龄产蛋量、蛋和蛋壳质量、一些血液代谢物和营养素保留的影响。母鸡(ISA 棕色蛋鸡)被随机分配到 40 个笼子中;每个处理组 10 个笼子,每个笼子 2 只母鸡。处理组为对照组(T1)、T2(益生菌:1 g Bio-plus2B®(地衣芽孢杆菌和枯草芽孢杆菌)/kg 饲料)、T3(益生元:1 g Techno Mos®(甘露寡糖(MOS)和 1,3 B-葡聚糖)/kg 饲料)和 T4(合生元:1 g Bio-plus2B®加 1 g Techno Mos®/kg 饲料)。
母鸡日产蛋率%和产蛋量显著增加(P<0.05),T2 和 T4 处理组均有增加。实验组记录到白蛋白指数、哈夫单位(P<0.01)、蛋壳厚度(P<0.05)、粗蛋白(CP)、粗脂肪(CF)和乙醚提取物(EE)的保留量增加(P<0.05)、血浆球蛋白、白蛋白和总蛋白(P<0.001)与未处理组相比,而蛋重不受影响。合生元处理组蛋壳钙含量显著增加(P<0.001)。T3 和 T4 处理组血浆胆固醇(P<0.001)和低密度脂蛋白(LDL)(P<0.05)显著降低。实验组丙氨酸转氨酶(ALT)显著降低(P<0.001),雌二醇激素升高(P<0.001)。
在产蛋早期母鸡日粮中添加益生菌和/或益生元对提高产蛋量和蛋壳厚度有有益的效果。
