饮用水中添加褐藻寡糖对肉鸡规模养殖场效益的影响

Impact of Adding Alginate Oligosaccharide to Drinking Water on the Efficiency of Broiler Farms

摘要:

本研究旨在探讨褐藻寡糖作为饲料添加剂在规模肉鸡养殖中的潜在效益。尽管褐藻寡糖已被证实具有免疫调节功能,但目前尚缺乏将其直接应用于规模场肉鸡饮水中的研究。为填补空白,本试验从2023年4月起,在肉鸡养殖场的饮水系统中添加褐藻寡糖粉,记录肉鸡的体重增长、死淘情况。结果表明:褐藻寡糖组比对照组肉鸡上市均重高0.22 kg,死淘差异极其显著(P＜0.001)。此外,通过成本核算进一步证实褐藻寡糖作为一种饲料添加剂的经济效益。这些发现不仅为褐藻寡糖在肉鸡养殖中的应用提供了科学依据,也为养殖业者在选择饲料添加剂时提供了新的参考。

Abstract:

This study was designed to explore the potential benefits of alginate oligosaccharides as a feed additive in largescale broiler farming.Despite the fact that alginate oligosaccharides have been confirmed to possess immunomodulatory functions,there is currently a dearth of research on their direct application in the drinking water of broilers on a largescale farm.To bridge this gap,starting from April 2023,alginate oligosaccharides powder was added to the drinking water system in a broiler farm in this experiment,and the weight gain and mortality and culling of broilers were recorded.The results indicated that there was a 0.22 kg difference in the average market weight of broilers between the alginate oligosaccharides group and the control group,and the difference in mortality and culling was highly significant(P<0.001).Additionally,the economic benefits of alginate oligosaccharides as a feed additive were further substantiated through cost accounting.These findings not only furnish a scientific basis for the application of alginate oligosaccharides in broiler farming but also offer a new reference for farmers in the selection of feed additives.
