[The behavior of hematological parameters (hemoglobin, hematocrit, leukocyte count) and clinicochemical values in plasma (glucose, total proteins, alpha-amino-N, urea, pepsinogen, ascorbic acid, Fe, Cu, Zn) and the content of ascorbic acid in liver, spleen and adrenal glands in healthy lambs and lambs infected with Haemonchus contortus and Trichostrongylus colubriformis].

In 8 healthy, noninfected lambs with an initial body weight (b. w.) of 24.79 +/- 1.16 kg as well as in 3 groups of lambs (n = 8 per group) of a similar body weight after an inoculation with 3rd stage larvae of Haemonchus contortus (2500) and Trichostrongylus colubriformis (10,000) analyses of the blood plasma were performed for 45 days thereafter. On the 37th day after infection ivermectin (0.2 mg/kg b. w.) was administered per os respectively subcutaneously to the lambs of 2 groups. After 7 and 8 days the content of ascorbic acid in the liver, the spleen and the adrenals as well as that of vitamin A in the liver was analysed. The behaviour of the values influenced by a moderate infection with trichostrongylid nematodes is discussed.
