Influence of Aflatoxin Present in Forages and Concentrated Feedingstuffs on Milk and Some Serum Biochemical Parameters in Goats

Abstract

Eight private farms as groups were used in the study. Each group contained randomly selected ten goats. These animals were fed forage and concentrated feed. Serum glucose, total protein.. albumin, globulin, cholesterol, and triglyceride levels, and ALP (alkaline phosphatase), ALT (alanine -amino transferase), AST (aspartate amino transferase), GGT (gamma-glutamyl transferase), and LDH (lactate dehydrogenase) activities were analysed. There were no correlations between glucose, ALP, AST, GGT and feed total aflatoxin (AF) concentrations. There were positive correlations between feed AF and LDH activities (P < 0.01), between feed AF and milk aflatoxin M1 (AFM1) (P < 0.01). On the other hand, there was a negative correlation (P < 0.01) between feed AF and total protein levels were also present. There was negative correlation between ALT concentration (P < 0.05) and AF in feed. There was negative correlation between concentrations of albumin and globulin (P < 0.01) and positive correlation between triglyceride concentration (P < 0.05) and AF level in feed. It was noticed that a marked increase in the level of AFM1 in milk due to an increase in total aflatoxin levels in feeds (P < 0.01).
