Using natural zeolites as a food additive in poultry diets offers an intriguing perspective. The objective of this study was to investigate the effects of zeolite addition and particle size on broiler performance, carcass characteristics, meat quality, moisture of excreta and litter, and intestinal measurements during 35 days.
A total of 560 1-day-old female Ross-308 broilers were divided into five treatment levels (0, 5, 10, 15, and 20 g zeolite/kg diet) ( = 16 replicates/treatment, = 8 replicates /particle size of each treatment). Performance was calculated weekly. Carcass characteristics, meat quality, small intestine (SI) measurements, litter pH, and moisture content were determined on day 35.
Litter pH, breast redness, cooking loss, chewiness, total weight, and SI length were all affected by zeolite treatments ( < 0.05). Particle size had an impact on the gastric pH and texture analysis. Their interaction had an effect on color redness, litter pH, and cooking loss. Performance was unaffected by either the main or interaction effects.
Zeolite as a feed additive may be useful in broiler diets, particularly large particles. The performance and production efficiency factor improved numerically ( > 0.05) with increasing zeolite doses up to 10 g zeolite/kg diet.
在家禽日粮中使用天然沸石作为食品添加剂提供了一个有趣的视角。本研究的目的是调查添加沸石和颗粒大小对35天内肉鸡生长性能、胴体特性、肉质、排泄物和垫料湿度以及肠道指标的影响。
总共560只1日龄雌性罗斯308肉鸡被分为五个处理水平（0、5、10、15和20克沸石/千克日粮）（每个处理16个重复，每个处理的每个颗粒大小8个重复）。每周计算生长性能。在第35天测定胴体特性、肉质、小肠（SI）指标、垫料pH值和水分含量。
垫料pH值、胸脯发红程度、蒸煮损失、咀嚼性、总重量和SI长度均受沸石处理的影响（P<0.05）。颗粒大小对胃pH值和质地分析有影响。它们的交互作用对发红程度、垫料pH值和蒸煮损失有影响。生长性能不受主效应或交互作用的影响。
沸石作为饲料添加剂在家禽日粮中可能有用，特别是大颗粒沸石。随着沸石剂量增加至10克沸石/千克日粮，生长性能和生产效率因子在数值上有所改善（P>0.05）。
