The studies analyse the effect of straw on lamb welfare, production and meat quality in finishing lambs. Two studies were carried out. Study 1 included two treatments and two replicates with six lambs each (17.20±0.2 kg). One pen was provided with straw for forage and bedding while the other had none. Feeding with concentrate was ad libitum. Live weight and concentrate consumption were recorded and average daily gain and conversion index calculated. Stereotypes, agonistic and affiliative interactions and physiological indicators of stress were analysed. In study 2, 24 lambs were divided into two groups to analyse the effect of treatments on meat and carcass quality. No significant differences in production or meat quality traits were observed. Lambs housed without straw had higher levels of cortisol and stereotypes. Affiliative interactions were greater in lambs without straw. Results suggest that straw can be considered an effective environment-enriching tool to improve welfare.
本研究分析了秸秆对育肥羔羊福利、生产性能和肉质的影响。进行了两项研究。研究 1 包括两个处理和两个重复，每个重复有 6 只羔羊（17.20±0.2kg）。一个围栏提供秸秆作为饲料和垫料，而另一个围栏没有。精饲料的喂养是自由采食的。记录活重和精饲料的消耗量，并计算平均日增重和转化率。分析刻板行为、竞争和亲和行为以及应激的生理指标。在研究 2 中，将 24 只羔羊分为两组，以分析处理对肉质和胴体质量的影响。生产性能或肉质特征没有显著差异。没有秸秆的羔羊的皮质醇和刻板行为水平更高。没有秸秆的羔羊的亲和行为更多。结果表明，秸秆可以被视为一种有效的环境丰富工具，以提高福利。
