Des chèvres infestées auparavant avec 100 métacercaires vivants de Fasciola gigantica et traitées avec du rafoxanide (Ranide, 7,5 mg/kg) à la quatrième semaine n'ont pas été protégées contre une invasion homologue de 250 métacercaires administrés deux semaines plus tard. La réinfestation s'est traduite par des lésions hépatiques plus sévères et un fort pourcentage de trématodes a été retrouvé par rapport à la première infestation. Cependant, la taille des trématodes de la seconde infestation (épreuve) était considérablement réduite. L'activité de l'enzyme plasmatique de l'aspartate amino-transférase (AST), du glutamate-dehydrogénase (GD) et du sorbitol déhydrogénase (SD) s'est élevée à un niveau comparable au cours des deux infestations. Cependant, la réponse des anticorps plasmatiques de F. gigantica était moins prononcée chez les chèvres réinfestées.

Abomasal Displacement

The main aim of the present field study was to evaluate various haematological parameters in cows with left abomasal displacement (LDA) and concurrent hepatic lipidosis (fatty liver) of different severity. A further objective was to compare these haematological values among animals with concurrent LDA and fatty liver that finally died or recovered. Sixty eight Holstein dairy cows with LDA and 110 control cows were included in the study. Blood and liver biopsy samples were obtained during standing LDA surgery. Liver tissue was examined histologically and classified according to the severity of fatty liver. Haematological analysis and biochemical determination of total lipids and triglycerides concentration of liver tissue were performed. The majority of the haematological parameters evaluated were within normal range. Haematocrit and haemoglobin median values were significantly lower in all LDA cows compared to controls, but no difference was recorded among fatty liver severity groups. Haematological parameters showed no significant difference in animals that finally died compared to the ones that recovered. Haematological parameters were not significantly influenced by the concurrence of LDA and fatty liver in dairy cows.

Condition Score

The aim of this study was to assess the severity and distribution of hepatic lipidosis in high-yielding dairy cows during the transition period by the evaluation of body condition score (BCS), serum levels of non-esterified fatty acids (NEFA) and β-hydroxybutyrate (BHB) and histological liver lipid content (GdL). Twenty-seven dairy cows, with a milk production of ~10 000 kg per year were enrolled in an experiment. Clinical examination was performed to evaluate the health status or the presence of periparturient diseases after calving. Animals were divided into two groups: healthy (HG; n = 11) and sick (SG; n = 16). The evaluation of BCS, NEFA, BHB and liver biopsies were performed at 15 ± 5 days prepartum (T0), 10 ± 2 days postpartum (T1), 30 ± 2 days postpartum (T2) and 50 ± 2 days postpartum (T3). Two-way repeated-measure ANOVA was applied to assess statistical significance of sampling time and between groups for all variables. Pearson’s correlation coefficient was used to investigate the relationship between all variables. Results showed BCS loss from T0 to T3 in SG and a significant increase of NEFA and BHB at T1. The GdL began to be mild at T0 increasing and becoming moderate to severe at T1, fairly regressing, but not disappearing, at T2 and T3, in both groups. This study showed that high lipomobilisation with a mild to moderate fat infiltration does not imply that ketosis or other periparturient diseases might be present. Our results suggest that hepatic lipidosis is associated with long-term histological and metabolic changes in dairy cows.
