Resumo: The objective of this study was to analyze the effects of anthelmintic treatment and supplementation of post-weaning Nellore calves. The parasitism degree, hematological changes and animal performance were analyzed, as well as the financial viability. One hundred contemporary Nellore calves were used. Animals were divided into four groups: CS+AT: supplementation with concentrate and anthelmintic treatment; CS: supplementation with concentrate; PS+AT: protein mineral supplementation and anthelmintic treatment; PS: protein mineral supplementation. Coproparasitological, hematological, and cost examinations were performed, and productive performance was also evaluated. A completely randomized design was used. Animals that received CS+AT showed greater weight gain. In females, there was significant difference in egg counts per gram of feces only between the CS and PS+AT. In males, animals receiving CS+AT, CS, and PS+AT differ from those receiving PS. No significant effects were observed for total plasma protein, packed cell volume, and eosinophils count. Females which received PS+AT and males who received CS+AT showed higher profitability. This study concludes that effective anthelmintic use is still viable, with higher profitability associated with concentrated supplementation in males, and mineral protein supplementation in females. Male calves show better return over investment when compared to females, due to the higher market value and higher potential performance.

Foram avaliados o grau de parasitismo, variações hematológicas e desempenho dos animais, bem como a viabilidade financeira. Foram utilizados 100 bezerros contemporâneos da raça Nelore. Os animais foram divididos em quatro grupos: SC+TA: Suplementação com concentrado e tratamento anti-helmíntico; SC: Suplementação com concentrado; SP+TA: Suplementação mineral proteica e tratamento anti-helmíntico; SP: Suplementação mineral proteica. Foram realizados exames coproparasitológicos, hematológicos e de custo, o desempenho produtivo também foi avaliado. Foi utilizado o delineamento inteiramente casualizado. Os animais que receberam SC+TA apresentaram maior ganho em peso. Nas fêmeas foi observada diferença significativa na contagem de ovos por grama de fezes somente entre os SC e SP+TA. Nos machos, os animais que receberam SC+TA, SC e SP+TA diferiram em relação ao SP. Para proteína plasmática total, volume globular e contagem de eosinófilos não foram observados efeitos significativos. Fêmeas que receberam SP+TA e os machos que receberam SC+TA apresentaram maior rentabilidade. Conclui-se que o uso de anti-helmíntico eficaz ainda é viável, apresentando maior rentabilidade associado à suplementação com concentrado nos machos e suplementação mineral proteica nas fêmeas. Bezerros machos respondem melhor aos investimentos, quando comparado às fêmeas, devido ao maior valor de mercado e maior potencial de desempenho.UEL2017-06-13info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/2657910.5433/1679-0359.2017v38n3p1551Semina: Ciências Agrárias; Vol. 38 No. 3 (2017); 1551-1560Semina: Ciências Agrárias; v. 38 n. 3 (2017); 1551-15601679-03591676-546Xreponame:Semina.
