Resumo: | In this study, the objective was to evaluate the efficacy of protein supplementation on gastrointestinal nematode control in lambs naturally infected. Sixty weaned Ile de France and Texel crossbred lambs, with 60 days of age, were divided into three groups (n=20) according to the level of protein in the concentrate: low protein (LP; 8.5%), moderate protein (MP; 15%), and high protein (HP; 25%). The daily amount of concentrate offered was based on 3% of live weight, which was continued throughout the experiment of 98 days. Evaluations were conducted biweekly from days 0 (D0) to 98 (D98). There were no significant differences (p > 0.05) in the average weight among the LP, MP and HP groups, which was 22.0, 21.4, and 21.1 kg, respectively, on D0 and 46.4, 48.3, and 48.2 kg, respectively, on D98. The daily weight gain was not significantly different among the groups (LP, 250 g; MP and HP, 276 g; p > 0.05). The average egg count per gram of feces (epg) of the LP group on D98 (6,765; an increase of 5,690 epg from D0) was higher than that of the MP and HP groups (1,617.5, p < 0.05 and 3,435, p > 0.05, respectively), which remained constant throughout the study. The hematocrit values decreased (p < 0.05) from D0 to D98 only in the LP group. Only in the HP group (p < 0.05), the mean serum total protein concentration increased from D0 (5.3 g dL-1) to D98 (5.8 g dL-1). The average albumin level on D98 (2.10 g dL-1) was lower than that on D0 (2.52 g dL-1) in the LP group (p < 0.05). During the study, 10 lambs overall were treated with anthelmintic because the epg values exceeded 10,000; six treated lambs were from the LP group, 3 from the HP group, and only 1 from the MP group. These results indicate that supplementation of diet with 15% protein increases the resistance and resilience of lambs to gastrointestinal parasites. |

Foram utilizados 60 cordeiros desmamados, com 60 dias de idade, mestiços Ile de France e Texel, divididos em três grupos (n=20) de acordo com o nível de proteína no concentrado: proteína baixa (PB; 8,5%), proteína moderada (PM; 15%) e alta proteína (AP; 25%). A quantidade diária de concentrado oferecida foi baseada em 3% do peso vivo, que se manteve ao longo do período experimental de 98 dias. As avaliações foram realizadas quinzenalmente a partir do dia 0 (D0) ao dia 98 (D98). Não houve diferença (p > 0,05) no peso médio dos grupos BP, MP e AP, iniciando em D0 com 22,0 kg, 21,4 kg e 21,1 kg, e finalizando em D98 com 46,4 kg, 48,3 kg, 48,2 kg, respectivamente. Não houve diferença significativa (p > 0,05) no ganho médio de peso diário entre os diferentes grupos (PB, 250 g; PM e AP, 276 g). A contagem média de ovos por grama de fezes (opg) do grupo PB no D98 (6.665 opg, aumento de 5.690 opg em relação ao D0) foi maior que a dos grupos PM e AP (1.617,5, p < 0,05 e 3.435, p > 0,05, respectivamente), que permaneceu constante ao longo do estudo. Os valores de hematócrito diminuíram (p < 0,05), do D0 para D98, apenas no grupo PB. Somente no grupo AP (p < 0,05), a concentração sérica de proteína total aumentou do D0 (5,3 g dL-1) para D98 (5,8 g dL-1). O nível médio de albumina no D98 (2,10 g dL-1) foi menor do que no D0 (2,52 g dL-1) no grupo PB (p < 0,05). Durante o estudo, 10 cordeiros no total foram tratados com antihelmínticos, pois os valores de opg excederam 10.000; seis cordeiros tratados eram do grupo PB, três do grupo AP e apenas um do grupo PM. Estes resultados indicam que a suplementação com 15% de proteína aumenta a resistência e a resiliência dos cordeiros aos parasitas gastrointestinais.UEL2018-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/3053310.5433/1679-0359.2018v39n2p643Semina: Ciências Agrárias; Vol. 39 No. 2 (2018); 643-656Semina: Ciências Agrárias; v. 39 n. 2 (2018); 643-6561679-03591676-546Xreponame:Semina.
