The use of broiler litter as an emergency feed during droughts and other periods of feed shortages was evaluated in terms of its effect on the health of sheep. Pure broiler litter (i.e. excreta plus wood shavings), and litter mixed with 7.5 or 15% molasses were fed for 83 days to 2-year-old wethers. The addition of molasses to the litter caused a significant increase (p < 0.01) in feed intake and final body mass. Various parameters such as plasma enzyme activity, plasma metabolite concentrations and urine mineral and purine excretion did not differ among treatments. Histological evaluation revealed no liver or kidney pathology. Mild myocardial pathology was observed in all 3 treatment groups. This seems to be related to the presence of the ionophore-based coccidiostat, narasin, which was present in the litter at a concentration of 10 mg/kg. It is suggested that these histological lesions are of little practical significance and would not affect the health of sheep being fed the broiler litter as a survival feed.
对使用肉鸡垫料作为干旱及其他饲料短缺时期的应急饲料对绵羊健康的影响进行了评估。将纯肉鸡垫料（即排泄物加刨花）以及与7.5%或15%糖蜜混合的垫料喂给2岁的阉羊，持续83天。向垫料中添加糖蜜使采食量和最终体重显著增加（p<0.01）。各处理组之间的各种参数，如血浆酶活性、血浆代谢物浓度以及尿液矿物质和嘌呤排泄量均无差异。组织学评估未发现肝脏或肾脏病变。在所有3个处理组中均观察到轻度心肌病变。这似乎与垫料中存在浓度为10毫克/千克的基于离子载体的抗球虫药甲基盐霉素有关。建议这些组织学病变实际意义不大，不会影响将肉鸡垫料作为生存饲料喂养的绵羊的健康。
