Fator P® evaluation, an organic additive, in the feeding of lactating Holstein ¾ Cows to reduce infestations By Rhipicephalus (Boophilus) Microplus

Due the losses caused by the Rhipicephalus (boophilus) microplus tick in dairy cattle in several countries, this research evaluated the action of Factor P® as an aid in this ectoparasite control. This organic additive is supplied daily in the diet through supplementation. For this, 20 lactating Holstein cows were selected. The animals were divided into two groups, Treated Group (TG) and Control Group (CG). The animals were stratified based on the count of telegynes above 4.5 mm, present on the left side of each animal. To evaluate the action of the additive, counts were performed on days 3, 5, 7, 14, 21, 28, 57, 86, 115, 144, 172, 200, 227, 254 and 281 after the beginning of treatment. Over the 281 days, the control group received 28 sprays and the group treated with Factor P® received 10 sprays, 64% fewer interventions. Thus, it is concluded that the additive had an auxiliary effect in the control of bovine ticks, reducing the percentage of infestation, the use of acaricides and reducing additional management, favoring animal and environmental well-being with cost reduction, since using the additive Factor P®, the milk doesn't need to be discarded as in the case of conventional treatment.
