The aim of the present study was to investigate the effect of supplementation of multistrain probiotic preparation in combination with vitamins and minerals to the broiler chicken diets on their growth performance, hematological parameters, and carcass traits.
Two hundred and eighty-eight Lohmann 1-day-old broiler chicks were randomly allocated to four groups, i.e., control (without additional supplementation) and three experimental treatments where basal diet was enriched by 0.1%, 0.5%, or 1% of multistrain probiotic preparation in combination with vitamins and minerals, respectively. Blood sampling was conducted on day 28, while the selected organs and eviscerated carcasses were collected on day 42.
Dietary supplementation did not affect (p>0.05) the final body weight, feed intake, and feed conversion ratio of broilers. Supplementation by 0.1% and 0.5% of multistrain probiotic preparation in combination with vitamins and minerals reduced (p≤0.05) heart relative weight of broilers. Dietary supplementation tended (p=0.07) to increase the relative weight of ileum and pancreas of broilers. Supplemented birds had lower (p≤0.05) numbers of leukocytes and eosinophils compared to unsupplemented birds. There were tendencies that supplementation of multistrain probiotics in combination with vitamins and minerals resulted in lower (p=0.07) counts of lymphocytes and heterophils when compared with no supplementation. Supplementation by 0.5% of multistrain probiotics in combination with vitamins and minerals resulted in lower (p≤0.05) serum concentration of uric acid when compared with control. There was no significant effect of dietary supplementation on carcass traits, pH, and drip loss of broiler breast muscles.
Dietary supplementation of commercial broiler feeds with 0.5% of multistrain probiotic preparation in combination with vitamins and minerals was potential to improve digestive functions and physiological status of broiler chickens.
本研究旨在探讨在肉鸡日粮中添加多菌株益生菌制剂与维生素和矿物质组合对其生长性能、血液学参数和胴体性状的影响。
288只1日龄罗曼肉鸡随机分为四组，即对照组（不添加额外物质）和三个试验处理组，分别在基础日粮中添加0.1%、0.5%或1%的多菌株益生菌制剂与维生素和矿物质组合。在第28天进行采血，在第42天收集选定器官和去内脏的胴体。
日粮添加对肉鸡的终末体重、采食量和饲料转化率没有影响（p>0.05）。添加0.1%和0.5%的多菌株益生菌制剂与维生素和矿物质组合可降低（p≤0.05）肉鸡的心脏相对重量。日粮添加有增加（p=0.07）肉鸡回肠和胰腺相对重量的趋势。与未添加的鸡相比，添加组的白细胞和嗜酸性粒细胞数量较低（p≤0.05）。与不添加相比，添加多菌株益生菌与维生素和矿物质组合有使淋巴细胞和异嗜性粒细胞计数降低（p=0.07）的趋势。与对照组相比，添加0.5%的多菌株益生菌与维生素和矿物质组合可降低（p≤0.05）血清尿酸浓度。日粮添加对肉鸡胴体性状、pH值和胸肌滴水损失没有显著影响。
在商品肉鸡饲料中添加0.5%的多菌株益生菌制剂与维生素和矿物质组合有改善肉鸡消化功能和生理状态的潜力。
