Stress Response to Long Distance Transportation of Common Carp (Cyprinus carpio L.)

The stress responses and changes in biochemical and haematological indices were investigated in three-year-old common carp (Cyprinus carpio L.) during a long-distance transportation in special truck tanks. Twelve-hour transportation caused a significant increase in ammonia (p < 0.01), mean corpuscular volume MCV (p < 0.01), metamyelocytes ( p < 0.05) and band neutrophils (p < 0.01), and a significant decrease in Cl- (p < 0.05), lactate (p < 0.05), ALT (p < 0.05) and ALP (p < 0.01) levels. The values of LDH (p < 0.01), AST (p < 0.05), CK (p < 0.01) and haematocrit PCV (p < 0.05) were also significantly influenced by the transportation, but no time-dependent relation was found. On the contrary, the levels of cortisol, glucose and total protein in the biochemical profile, and the values of erythrocyte count (RBC), haemoglobin (Hb), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), leukocyte counts (WBC) and leukogram (except for metamyelocytes and band neutrophils) in the haematological profile were not significantly influenced by the transportation. Results showed that pre-transport fish manipulation (hauling, netting, handling, loading) was found to be an important stressor for fish. Long-distance transportation itself was relatively considerate for the common carp tested

Neuro-fuzzy control design of processes in chemical technologies

The paper presents design of neuro-fuzzy control and its application in chemical technologies. Our approach to neuro-fuzzy control is a combination of the neural predictive controller and the neuro-fuzzy controller (Adaptive Network-based Fuzzy Inference System - ANFIS). These controllers work in parallel. The output of ANFIS adjusts the output of the neural predictive controller to enhance the control performance. Such design of an intelligent control system is applied to control of the continuous stirred tank reactor and laboratory mixing process

Effect of Low Environmental Temperature on Performance and Blood System in Broiler Chickens (Gallus domesticus)

The aim of this study was to assess the effect of low environmental temperature on growth, feed conversion, performance and selected biochemical and haematological indicators in broiler chickens. The decrease in air temperature since the 22nd day of growth influenced significantly (p p < 0.01) the level of triiodothyronine, haemoglobin (in male broiler chickens), haematocrit, abdominal fat content (in male broiler chickens), and heart weight too. The results have clearly confirmed that during growth, the decrease in environmental temperature (cold stress) negatively influenced some indices of performance and blood system in broiler chickens
