This study evaluated the possibilities of pumice (light stones) as litter material in broiler production. Experimental treatments included wood shavings (WS), acidic pumice (AP), and basic pumice (BP) alone, and in combination; wood shaving + acidic pumice (WSAP) and wood shaving + basic pumice (WSBP) in a ratio of 1:1. Two trials were performed, one in summer, and the other in winter. Each trial involved 750 mixed-sex Ross (308) broilers. Also, there were 15 replicate pens with 50 broilers and a stocking density of 12.5 birds/m for each pen at the beginning of each trial. Performance, litter quality, carcass parameters, body and leg abnormalities, body temperature, fear and stress responses, proportional asymmetry, and some behavior expressions were investigated. The litter treatment influenced the final live body weight, litter moisture, ammonia concentration, footpad dermatitis, hock burn, breast blister, hot carcass yield, heart, liver, spleen, abdominal fat, wing and neck ratio, breast and back cleanliness, and the expression of dust bathing and foraging behaviors (P < 0.01; P < 0.05). Furthermore, there was a seasonal effect on live body weight, feed conversion ratio, livability, litter pH, 42-day litter moisture, hot carcass yield, back cleanliness, footpad dermatitis, hock burn, footpad temperature, heterophil-to-lymphocyte ratio, and expression of pecking behavior (P < 0.01; P < 0.05). It is suggested that acidic pumice stone alone or in a mixture with wood shavings could be used as a reliable litter material, alternative to wood shavings.
本研究评估了浮石（轻石）作为肉鸡生产垫料材料的可能性。实验处理包括单独使用刨花（WS）、酸性浮石（AP）和碱性浮石（BP），以及将它们以 1:1 的比例混合使用；刨花+酸性浮石（WSAP）和刨花+碱性浮石（WSBP）。进行了两次试验，一次在夏季，另一次在冬季。每个试验涉及 750 只混性别罗斯（308）肉鸡。此外，每个试验开始时，每个试验都有 15 个重复的鸡舍，每个鸡舍有 50 只鸡，每只鸡的饲养密度为 12.5 只/只。研究了性能、垫料质量、胴体参数、身体和腿部异常、体温、恐惧和应激反应、比例不对称和一些行为表达。垫料处理影响最终活体体重、垫料水分、氨浓度、脚垫皮炎、跗关节烧伤、胸部水疱、热胴体产量、心脏、肝脏、脾脏、腹部脂肪、翅膀和颈部比例、胸部和背部清洁度以及灰尘浴和觅食行为的表达（P<0.01；P<0.05）。此外，活体体重、饲料转化率、成活率、垫料 pH 值、42 日龄垫料水分、热胴体产量、背部清洁度、脚垫皮炎、跗关节烧伤、脚垫温度、异嗜性白细胞与淋巴细胞比值和啄食行为的表达均存在季节性影响（P<0.01；P<0.05）。建议单独使用酸性浮石或与刨花混合使用可以作为一种可靠的垫料材料，替代刨花。
