Resumo: | This work aimed to evaluate clinical, parasitological and productive parameters of crossbred lambs under a rotational grazing system of Panicum maximum cv. Aruana grass fertilized with four doses of nitrogen (75, 275, 475 and 675 kg ha-1 year-1). Eighteen lambs were used per treatment, totaling 72 animals. The following parameters were evaluated: daily weight gain (DWG), total weight gain (TWG), stocking rate (SR), meat production, number of fecal eggs per gram (EPG) and coproculture. Deworming was accomplished according to conjunctiva color compared using the Famacha© card. DWG and TWG were greater (p < 0.05) in the animals under pasture fertilized with 75 kg ha-1 year-1. However, SR and EPG were greater (p < 0.05) in the animals kept in pastures with 675 kg ha-1 year-1. There were no significant differences among nitrogen levels for the different colors of ocular mucosa or the number of animals dewormed. A prevalence of 80.0 to 93.0% of Trichostrongylus sp. was found. The deworming based on the evaluation of conjunctiva color did not reduce EPG into desirable levels for any of fertilized doses of nitrogen. The nitrogen dose of 475 kg ha-1 year-1 in Aruana grass allowed greater productive performance per hectare. |

Aruana adubado com quatro doses de nitrogênio (75, 275, 475 e 675 kg ha-1 ano-1). Foram utilizados 18 cordeiros por tratamento, perfazendo um total de 72 animais. Foram avaliados os seguintes parâmetros: ganho médio diário (GMD), ganho de peso total (GPT), taxa de lotação (TxL), produção total de carne, contagem do número de ovos por grama de fezes (OPG) e coprocultura. A vermifugação dos animais foi realizada de acordo com a coloração da mucosa ocular comparada por meio do cartão Famacha© Foi verificado que tanto o GMD quanto o GPT foram maiores (p < 0,05) nos animais mantidos na pastagem com adubação nitrogenada 75 kg ha-1 ano-1. Todavia, a TxL e o OPG foram maior (p < 0,05) nos animais mantidos na pastagem adubada com 675 kg ha-1 ano-1. Não houve diferença significativa entre as doses de adubação para os diferentes tons de coloração da mucosa ocular nem para o número de animais vermifugados. Observou-se uma prevalência de 80,0 a 93,0% de larvas de Trichostrongylus sp. A vermifugação baseada na avaliação da mucosa ocular não permitiu a redução do OPG para nenhuma das doses de adubação adotadas. A dose de nitrogênio de 475 kg ha-1 ano-1 promoveu melhor desempenho produtivo por hectare.Editora da Universidade Estadual de Maringá2011-04-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpesquisa de campoapplication/pdfhttps://periodicos.uem.br/ojs/index.php/ActaSciAnimSci/article/view/940610.4025/actascianimsci.v33i2.9406Acta Scientiarum.
