摘 要:【目的】评价自主研发降污牛床的降污性能,以提高牛床的干燥度和牛群躺卧行为的舒适度。【方法】选择体况和体质量基本一致的西杂育肥肉牛12头,随机均分为2组,分别饲养在混凝土实心地板牛床(对照组)和降污牛床(试验组)上,测试2种牛床的表面干燥度和卫生评分,评价2种牛床对牛群体表清洁度以及躺卧、反刍等行为的影响。【结果】降污牛床被尿液污染的面积比对照牛床少,微缝清理4次时的干粪覆盖面积显著大于清理2~3次时(P<0.05)。降污牛床牛群的体表清洁度评分显著低于对照牛群(P<0.05)。2组牛群的站立行为虽无显著差异(P>0.05),但牛群在降污牛床的躺卧时间较对照牛床有所增加。降污牛床牛群的反刍时间和次数极显著或显著高于对照组(P<0.01或P<0.05)。【结论】降污牛床的干燥度、卫生状况和牛群体表清洁度较好,拴系育肥肉牛躺卧和反刍时间得到了较大幅度的提升。[Purpose]To evaluate the pollution reduction performance of the independently developed cattle bed with reducing pollution(CBRP-bed),improving the dryness of cattle bed and the comfort of lying behaviors.[Methods]A total of 12 tied-stall fattening beef cattle with similar body condition and body weight were averagely and randomly assigned to concrete floor cattle bed(Ctrl-bed,control group)and CBRP-bed(experimental group);and then,the surface dryness and hygiene score of two types of cattle beds were tested,and the effects of the two types of cattle beds on the cleanliness of the cattle body and the behavior of lying down and rumination were evaluated.[Results]The urine contamination area of CBRP-bed was less than that of the Ctrl-bed;the area of CBRP-bed covered with dry manure was significantly greater when cleaned micro-crack four times,comparing with two and three times(P<0.05).The body surface cleanliness score of the cattle on CBRPbed was significantly lower than that on Ctrl-bed(P<0.05).There was no significant difference in the standing behavior of the two groups of cattle(P>0.05),but the lying time of the cattle on CBRP-bed was increased compared to Ctrl-bed.The rumination time and frequency of the cattle group on CBRPbed were significantly higher than those on Ctrl-bed.(P<0.05 or P<0.01).[Conclusion]The dryness,sanitation,and body surface cleanliness of the cattle on CBRP-bed are better,and the lying and rumination time of the tied-stall beef cattle have been significantly improved.
