Efeito do uso da Promixalicina no controle de verminose e parâmetros sanguíneos de ovelhas

Sheep producers are increasingly looking for strategies to tackle the problem of worms in animals, as well as to improve the functioning of the animals' immune system. Therefore, two experiments were carried out in two different properties (with high and low challenges in relation to verminoses) with the objective of evaluating the effect of Ovine Promixalicin on the EPG (eggs per gram) of feces, and blood parameters of pregnant and non-pregnant sheep, on two different properties. The indication for use of the product is to, among others, contribute to the control of verminoses. The animals evaluated on the properties came from a pasture production system, with the use of concentrated and/or roughage supplementation if necessary. The animals used were of the Dorper, Texel, Ile de France and Sulfolk breeds. The parameters evaluated were EPG, Famacha, Body Condition Score and blood parameters (lymphocytes, leukocytes and erythrocytes). In relation to experiment 1, with a low challenge in relation to worms, the use of Promixalicin significantly helped reduce worms and improve animal well-being, thus aiding the herd in increasing productive parameters such as weight gain and fertility. In experiment 2, a system with a high challenge in terms of verminoses, the animals remained uniform and controlled by the use of Promixalicin, including beneficial results in relation to blood parameters, which did not increase during its use. Therefore, the use of Ovine Promixalicin does not alter feed intake in animals, and is effective in controlling verminoses, including Haemonchus contortus, Trichostrongylus colobriformis, Oesophagostomum columbianum e Strongyloides papillosus, promoting well-being and maintenance of the immune system, especially in pregnant animals, bringing benefits to the sheep production system.
