摘要: This study examined tropical pasture contamination dynamics under different feeding systems for finishing lambs. The experiment aimed to evaluate the vertical distribution of gastrointestinal helminth infective larvae (L3) in erect grass subjected grazing and assess parasite load its impact on lamb performance three production systems. Three treatments based Aruana (Panicum maximum cv. IZ-5) were as follows: T1, only; T2, with 1.5 % body weight (BW) nutrient concentrate supplementation; T3, 2.5 BW supplementation. randomized block design had replicates treatments, six lambs per replicate. L3 recovered from strata (upper, middle, bottom), each representing one third sward height, correlated microclimatic data. Significant differences (P 0.05). Pasture microclimate did not correlate larval recovery. At end experiment, animal fecal egg count was similar among > results indicated that a grassland caused height but affect strata. Larvae found base top sward.
