In the Experimental Farm of the Universidade Federal de Lavras (EF-UFLA), state of Minas Gerais, Brazil, on their day of birth, female Holstein calves were randomly selected and placed into two groups containing fifteen animals each: Strategic-Selective Treatment (S-ST) or Conventional Treatment (CT). In the S-ST, calves were treated after coproparasitological examinations according to criteria established previously by the researchers. Calves in the CT were treated according to the opinion of the veterinarian of EF-UFLA. For statistical analysis, the frequency (%) of fecal samples with count of eggs per gram of feces (EPG) ≥300, count of oocysts per gram of feces (OoPG) ≥500 and fecal samples with count of cysts of Giardia spp. ≥1 were conducted. The overall average frequency of fecal samples with EPG ≥300, OoPG ≥500 and Giardia spp. cysts ≥1, respectively, was similar (p >0.05) between S-ST (20.3%; 17.3%; and 31.5%) and CT (26.4%; 23.9%; and 37.3%). The effective operational cost, per animal, in 12 months, was of R$ 784.58 (US$ 241.41) and R$ 83.90 (US$ 25.81) in S-ST and CT, respectively. The S-ST requires adjustments to be used as a technically efficient and economically viable alternative for the control of gastrointestinal parasitosis in female Holstein calves.
在巴西米纳斯吉拉斯州拉夫拉斯联邦大学的实验农场（EF-UFLA），雌性荷斯坦犊牛在出生当天被随机挑选出来，分成两组，每组15头：战略选择性处理组（S-ST）和传统处理组（CT）。在S-ST组中，犊牛根据研究人员先前制定的标准进行粪便寄生虫学检查后接受治疗。CT组的犊牛则根据EF-UFLA兽医的意见进行治疗。为了进行统计分析，对每克粪便虫卵计数（EPG）≥300、每克粪便卵囊计数（OoPG）≥500以及每克粪便贾第虫属囊肿计数≥1的粪便样本频率（%）进行了统计。S-ST组（20.3%；17.3%；31.5%）和CT组（26.4%；23.9%；37.3%）中，EPG≥300、OoPG≥500以及贾第虫属囊肿≥1的粪便样本总体平均频率分别相似（p>0.05）。S-ST组和CT组每头动物12个月的有效运营成本分别为784.58雷亚尔（241.41美元）和83.90雷亚尔（25.81美元）。S-ST需要进行调整，才能作为控制雌性荷斯坦犊牛胃肠道寄生虫病的技术高效且经济可行的替代方法。
