Résumé partiel
Analysis of hot ambience associated alterations in liver enzymes of pathways of carbohydrate metabolism in non-descript goat from arid tracts was carried out in the present investigation. Liver sample were collected from male and female non-descript goat ageing from 3 to 12 months during mild (months of October and November) and extreme hot (May, June and July) ambiences from private slaughter houses. The male and female animals were categorized as 3-6 months ; 6-9 months and 9-12 months of age groups in each ambience. To accomplish the objectives of the investigation, enzymes of pathways of carbohydrate metabolism (hexose monophosphate shunt, gluconeogenesis, glycolysis, TCA cycle and miscellaneous metabolic reactions ) and glycogen were measured in the liver during mild and extreme hot ambiences. The enzymes incorporated in the study were glucose-6phosphate dehydrogenase (G6PDH) ; glucose-6-phosphatase (Glc-6Pase) ; phosphoenol pyruvate carboxykinase (PEPCK) ; aspartate aminotransferase (AST) and alanine aminotransferase (ALT) ; aldolase (ALD) ; hexokinase (HK) ; phosphoglucose isomerase (PGI) ; glyceraldehyde-3-phosphate dehydrogenase (GAPDH) ; pyruvate kinase (PK) ; isocitrate dehydrogenase (ICDH) ; malate dehydrogenase (MDH) ; lactate dehydrogenase (LDH) ; glutamate dehydrogenase (GDH) and sorbitol dehydrogenase (SDH). Control mean value was obtained during mild ambience for each parameter. Then the mean value obtained during extreme hot ambience was compared from respective control value of the analyte. Supervision of the effect of sex and age group was also determined. Per cent changes in analytes during extreme hot ambience were calculated to analyze the hot ambience associated alterations in liver enzymes of pathways of carbohydrate metabolism. Interactions of sex X age group ; ambiences X sex ; ambiences X age groups ; ambiences X sex X age groups for enzymes of pathways of carbohydrate metabolism and glycogen in the liver were calculated and were found to be highly significant (p≤0.01) divulging the supremacy of impacts in each group. ii A significant (p≤0.05) rise in the mean values of all liver enzymes was observed during extreme hot ambience as compared to respective mild ambience mean value except for GAPDH and PK, which revealed a significant (p≤0.05) decline in the mean values.
