Several alternative feed additives to replace AGP to maintain good quail performance include the use of probiotics and herbal extracts.
In this study, the researchers want to find out the best dosage of microbiota inoculum as probiotics ( and ), single garlic extract (), and combination groups to improve laying quail egg production, hematology profile (erythrocytes, hemoglobin, hematocrit, leukocytes, and platelets), and reproductive organs in terms of length and weight and have better egg quality on the internal (Haugh units, yolk score, albumin index, yolk index) and external (shell thickness, egg weight) while laying phase of laying quail.
A total of 100 4-week-old laying quails of uniform body weight were randomly distributed into five treatments with four replicates each and five quails in each replicate. There were 5 treatment groups: T0 quails were given basal feed; T1 quails were given basal feed and drinking water added with probiotics at a dose of 4 ml/l; T2 quails were given feed added with a single garlic extract at a dose of 2 ml/g and ordinary drinking water; T3 quails were given feed with a single garlic extract at a dose of 2 ml/g and drinking water supplemented with probiotics at a dose of 4 ml/l; and T4 quails were given a single garlic extract at a dose of 1 ml/g and drinking water supplemented with probiotics at a dose of 2 ml/l. The study investigated the effects of microbiota inoculum, including probiotics, garlic extract, and a control group, on reproductive organ morphologies in chickens. Results showed significant improvements in weight vagina, uterus, oviduct, ovarium, weight cloaca, growth performance, body weight, egg production, internal egg quality, yolk color score, yolk index, albumin index, external egg quality, Haugh unit, egg height, shape index, egg cell weight, and egg cell thickness.
The number of erythrocytes was significantly higher in the chickens treated with the microbiota inoculum compared to the control group. Hemoglobin levels were not significant in all treatments, but hematocrit levels were significant in the chickens treated with the microbiota inoculum. Leukocytes were also significantly higher in the chickens treated with the microbiota inoculum compared to the control group.
The use of a combination of microbiota inoculum in drinking water and garlic extract in feed has been proven to be effective in reducing feed consumption, maintaining hematology, increasing reproductive organs, and boosting the number of laying quail productions, thereby reducing feed conversion ratio.
几种可替代抗生素生长促进剂（AGP）以维持鹌鹑良好生产性能的饲料添加剂包括益生菌和草药提取物的使用。
在本研究中，研究人员想要找出作为益生菌的微生物接种物（和）、单一大蒜提取物（）以及组合组的最佳剂量，以提高产蛋鹌鹑的产蛋量、血液学指标（红细胞、血红蛋白、血细胞比容、白细胞和血小板）以及生殖器官的长度和重量，并在产蛋鹌鹑的产蛋期使蛋的内部品质（哈氏单位、蛋黄评分、蛋白指数、蛋黄指数）和外部品质（蛋壳厚度、蛋重）更好。
将总共100只体重均匀的4周龄产蛋鹌鹑随机分为五个处理组，每个处理组有四个重复，每个重复五只鹌鹑。有5个处理组：T0组鹌鹑给予基础饲料；T1组鹌鹑给予基础饲料并在饮水中添加剂量为4毫升/升的益生菌；T2组鹌鹑给予添加剂量为2毫升/克单一大蒜提取物的饲料和普通饮水；T3组鹌鹑给予添加剂量为2毫升/克单一大蒜提取物的饲料并在饮水中添加剂量为4毫升/升的益生菌；T4组鹌鹑给予剂量为1毫升/克的单一大蒜提取物并在饮水中添加剂量为2毫升/升的益生菌。该研究调查了微生物接种物，包括益生菌、大蒜提取物以及一个对照组，对鸡生殖器官形态的影响。结果显示阴道、子宫、输卵管、卵巢的重量、泄殖腔重量、生长性能、体重、产蛋量、蛋的内部品质、蛋黄颜色评分、蛋黄指数、蛋白指数、蛋的外部品质、哈氏单位、蛋高、形状指数、卵细胞重量和卵细胞厚度均有显著改善。
与对照组相比，用微生物接种物处理的鸡的红细胞数量显著更高。所有处理组的血红蛋白水平均无显著差异，但用微生物接种物处理的鸡的血细胞比容水平有显著差异。与对照组相比，用微生物接种物处理的鸡的白细胞数量也显著更高。
已证明在饮水中使用微生物接种物和在饲料中使用大蒜提取物的组合可有效降低饲料消耗、维持血液学指标、增加生殖器官并提高产蛋鹌鹑的产蛋数量，从而降低饲料转化率。
