The study was carried out to develop a wet litter model with magnesium chloride to assess the effectiveness of a polyherbal formulation (PHF) on growth performance, litter and cecal moisture (LCM) level, cecal consistency (CC) score, and footpad lesions (FPLs) score in Ross 308 broiler chickens.
1,200 one-day-old chicks were assigned into five groups: normal control, negative control [NTC; treated with 1.7% magnesium chloride hexahydrate (MgCl.6HO)], and three treatment groups, T1, T2, and T3, where 750, 1,000, and 2,000 gm/ton of PHF, respectively, were supplemented. All the groups were fed a basal diet until day 7. However, the NTC and treatment groups were fed a diet with MgCl from days 8 to 42.
The addition of MgCl for 35 days worsened the growth performance traits in broilers and induced wet litter problems (FPL, high LCM, and poor CC) in the NTC group. However, PHF (750, 1,000, and 2,000 gm/ton) ameliorated the negative effect of a diet with MgCl on growth performance and wet litter problems, but a better response with respect to LCM and CC was observed in 2,000 gm/ton of PHF group, followed by that in 1,000 gm/ton of PHF group and 750 gm/ton of PHF group on day 42.
The wet litter broiler model was developed through excessive feeding of MgCl, which caused the performance parameters to worsen and the emergence of problems associated with the wet litter. Supplementation with PHF ameliorated these problems and, therefore, it can be used for the management of wet litter in poultry.
开展本研究以建立一种含氯化镁的潮湿垫料模型,评估一种多草药配方(PHF)对罗斯308肉鸡生长性能、垫料和盲肠湿度(LCM)水平、盲肠稠度(CC)评分以及脚垫损伤(FPLs)评分的影响。
将1200只1日龄雏鸡分为五组:正常对照组、阴性对照组[NTC;用1.7%六水合氯化镁(MgCl₂·6H₂O)处理]以及三个处理组T1、T2和T3,分别添加750、1000和2000克/吨的PHF。所有组在第7天前饲喂基础日粮。然而,NTC组和处理组在第8天至42天饲喂含MgCl₂的日粮。
添加MgCl₂ 35天使肉鸡的生长性能指标恶化,并在NTC组引发了潮湿垫料问题(FPL、高LCM和差的CC)。然而,PHF(750、1000和2000克/吨)改善了含MgCl₂日粮对生长性能和潮湿垫料问题的负面影响,但在第42天,2000克/吨PHF组对LCM和CC的反应更好,其次是1000克/吨PHF组和750克/吨PHF组。
通过过量饲喂MgCl₂建立了潮湿垫料肉鸡模型,这导致性能参数恶化以及与潮湿垫料相关问题的出现。添加PHF改善了这些问题,因此,它可用于家禽潮湿垫料的管理。
