Abstract

Objective

Our objective was to evaluate how a particular zeolite-based flow agent affected ergot alkaloid digestion and physiological markers associated with fescue toxicosis.

Materials and Methods

Twenty-four steers (226 ± 27.6 kg) were used to test effects of enhanced zeolite-based flow agent (KALLSIL, Kemin Industries, Des Moines, IA) on ergot-like alkaloid digestion. Treatments were control (E+) or enhanced zeolite inclusion (E+Z; 2 g/kg, DM basis). Steers were limit-fed diets (1.8% of BW, DM basis) containing 465 μg of ergovaline/kg of DM. Rectal temperature and respiration rate were recorded daily at 0700 and 1200 h from steers in a room kept at 18.5°C ± 0.33°C, 32.6% ± 2.19% relative humidity. Blood was collected on d 1, 7, 14, and 21 to measure prolactin. On d 21 prolactin stores were measured following infusion of thyrotropin- releasing hormone (TRH; 1 μg/kg BW). Feces and urine were collected every 8 h from d 17 to 20, with 2-h advancement daily for digestibility, N balance, and recovery of ergot-like alkaloids.

Results and Discussion

Digestion and N balance were not affected by treatment. Zeolite did not affect fecal recovery of ergovaline. Serum prolactin declined over time. Serum prolactin was greater in steers fed E+Z. Following TRH infusion, prolactin was numerically greater for E+Z. Rectal temperatures and respiration rates were not affected by E+Z.

Implications and Applications

Under the conditions of this experiment, addition of this particular zeolite-based feed additive had minimal impact on ergot alkaloid recovery and physiological markers associated with fescue toxicosis.

增强型沸石基流动剂减轻肉牛食用麦角类生物碱影响的能力
材料和方法用 24 头阉牛(226 ± 27.6 千克)测试增强型沸石流动剂(KALLSIL,Kemin Industries,Des Moines,IA)对麦角类生物碱消化的影响。处理方式为对照组(E+)或添加增强型沸石(E+Z;2 克/千克,以 DM 计)。给阉牛饲喂的日粮(占体重的 1.8%,以 DM 为基础)每公斤 DM 含 465 μg 麦角碱。每天 7:00 和 12:00 在温度为 18.5°C ± 0.33°C、相对湿度为 32.6% ± 2.19% 的房间内记录公牛的直肠温度和呼吸频率。在第 1、7、14 和 21 天采集血液以测量催乳素。第21天,在注射促甲状腺激素释放激素(TRH;1 μg/kg体重)后测量催乳素储存量。从第 17 天到第 20 天,每隔 8 小时收集一次粪便和尿液,每天提前 2 小时测定消化率、氮平衡和麦角类生物碱的回收率。沸石不影响粪便中麦角碱的回收。血清泌乳素随时间推移而下降。饲喂 E+Z 的母牛血清泌乳素更高。输注 TRH 后,E+Z 的催乳素在数量上更高。意义和应用在本实验条件下,添加这种特殊的沸石饲料添加剂对麦角生物碱的恢复和与羊草中毒相关的生理指标影响很小。
