Abstract

This study evaluated the effects of two types of plastic flooring-one with and one without nanotechnological antimicrobial additives-used as complete or partial replacements for wood shavings on broiler chicken performance, yield, meat quality, and litter microbiology over 42 days. A total of 1500 Ross 408 male broiler chicks were randomly assigned to five treatment groups: wood shavings (WS), plastic flooring (PF), a 50/50 mix of plastic flooring and wood shavings (PF + WS), plastic flooring with antimicrobial additives (PFA), and a 50/50 mix of antimicrobial plastic flooring and wood shavings (PFA + WS). This study evaluated organ biometrics (liver, heart, spleen, and gizzard), the severity of lesions, microbiological profiles, performance indices, and meat quality. The results indicated that plastic flooring, particularly when used alone, presented challenges such as increased intestinal lesions related to coccidiosis and a higher prevalence of . Moreover, broilers raised on plastic flooring presented worse feed conversion and lower body weights and carcass yields than those raised on wood shavings. The meat quality was also negatively affected, with plastic flooring leading to less favorable fillet characteristics. Overall, the use of plastic flooring reduced the performance and health parameters of broiler chickens.

摘要

本研究评估了两种类型的塑料地板(一种添加了纳米技术抗菌添加剂,另一种未添加)作为刨花的全部或部分替代品,在42天内对肉鸡生长性能、产量、肉质和垫料微生物学的影响。总共1500只罗斯408雄性肉鸡雏鸡被随机分配到五个处理组:刨花(WS)、塑料地板(PF)、塑料地板与刨花50/50的混合物(PF + WS)、含抗菌添加剂的塑料地板(PFA)以及抗菌塑料地板与刨花50/50的混合物(PFA + WS)。本研究评估了器官生物特征(肝脏、心脏、脾脏和砂囊)、病变严重程度、微生物学特征、生长性能指标和肉质。结果表明,塑料地板,尤其是单独使用时,带来了一些挑战,如与球虫病相关的肠道病变增加以及更高的患病率。此外,在塑料地板上饲养的肉鸡比在刨花上饲养的肉鸡表现出更差的饲料转化率、更低的体重和胴体产量。肉质也受到负面影响,塑料地板导致鱼片特性更不理想。总体而言,使用塑料地板降低了肉鸡的生长性能和健康参数。
