Monitoring of changes in some blood laboratory parameters in 34 horses after ingesting freshly harvested maize that was to be used for ensiling, heavily contaminated with young Datura stramonium plants, is described. For a 7-day period the following parameters were monitored: haemoglobin content (HGB), red blood cell counts (RBC), white blood cell counts (WBC), haematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), differential white cell counts (DWC), erythrocyte sedimentation rate (ESR), protein fractions, aspartate aminotransferase (AST), lactate dehydrogenase (LDH), total bilirubin (TB), direct bilirubin (DB), blood glucose (Glu), total protein (TP), globulin (Glob) and albumin (Alb). The intoxication was accompanied by erythrocytosis, leukocytosis, regenerative left shift neutrophilia, lymphopaenia, eosinopaenia, increased haematocrit values, low erythrocyte sedimentation rate, hyperglycaemia, bilirubinaemia, hypoproteinaemia and increased activity of AST and LDH. No changes occurred in the mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), albumin, globulin and globulin fractions (a1, a2, b1, b2 and g). The blood parameters returned to normal between post-intoxication days 2 and 5. The observed changes in clinical chemistry indices could be used in the diagnosis, differential diagnosis and prognosis of Jimson weed intoxication.
Abstract. Aflatoxins are highly toxic fungal metabolites encountered in feed ingredients at various concentrations. The aim of this study was to investigate the effect of aflatoxin В1 administered either alone or with Mycotox NG on productive traits (body weight, weight gain, feed intake and feed conversion) in Pekin ducks. The birds were divided into one control and six experimental groups (n=10): group І (0 mg/kg AFB1 without Mycotox NG); group ІI (0.5 g/kg Mycotox NG); group ІІI (1.0 g/kg Mycotox NG); group IV (0.2 mg/kg AFB1); group V (0.4 mg/kg AFB1); group VI (0.2 mg/kg AFB1 + 0.5 g/kg Mycotox NG) and group VII (0.4 mg/kg AFB1 + 1.0 g/kg Mycotox NG). Trial duration was 42 days; changes in productive traits were determined on 14th, 28th and 42nd day. Lower productive traits in terms of body weight, daily weight gain and feed intake along with higher feed conversion ratio were found out in ducklings from experimental groups IV and V. The addition of 0.5 g/kg or 1.0 g/kg Mycotox NG to the diet of groups VI and VIII reduced or prevented the deleterious AFB1 effects on studied productive parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
