Resumo
The stress in animals can cause economic damage and reduction in quality of the final product. The discomfort caused by stress causes physiological, morphological and behavioral changes in the animals that end up reducing the level of well-being. The first variable to be changed in uncomfortable situations is the respiratory rate and heart rate. This study aimed to evaluate the change in heart rate and respiratory rate of sheep after two forms of anthelmintic treatment, oral and injectable. Thirty-four ewe lambs Lacaune breed selected by the degree of anemia were used (through Famacha method). The animals were allocated according to 2x2 factorial design, two groups of Famacha Group A: 1 and level 2 (20 animals) and Group B: Level 3 and 4 (14 animals), and two routes of administration (oral and injectable). Assessments of respiratory rate and heart rate were performed before, during and after administration of antihelminths. Analyses were performed using the statistical package JMP 8 (SAS Inst., Inc., Cary, NC), adopting a significance level of P 0.05. Respiratory rate had no effect of treatment and degree of Famacha not changing. Heart rate during treatment showed effect of the degree of anemia. This result can be explained by the mode of action of the parasites in its host, because helminth infection leads to anemia due to blood loss. Heart rate and respiratory rate were inO artigo não apresenta resumo em português.
