The present work was aimed to study the relation between the tapeworm Khawia armeniaca infection and some metabolic extents in both the parasitic tapeworm and the parasitized fish Barbus grypus, using LDH and transaminase activities as a vital connotation. 57 adult Barbus grypus fish (Hekle fish) were hunted from Tigris river - Rashidiya area -North of Mosul - Iraq. The adult tapeworm K. armeniaca were collected from small intestine of the fish. Extract of Liver and intestinal tissues of the infected and uninfected fish in addition to tapeworm tissues were prepared. Some macromolecules concentrations and LD, AST and ALT activities were assayed using colorimetric methods.The results revealed that concentration of proteins, carbohydrates and lipids were lesser significantly at P≤0.05 in the intestinal tissues of infected fish 176.92µg/gm wet weight, 147.21µg/gm wet weight and 112.14 mg/dl respectively than that of uninfected fish 264.70µg/gm wet weight, 223.71µg/gm wet weight and 176.37 mg/dl respectively. Concentration of lipids in the tapeworm tissues was relatively high 130.67mg/dl. As for Liver LDH activity, it was significantly higher in the infected fish 279.90 IU/L than that of the uninfected fish 253.56 IU/L. whereas, liver ALT activity was diminished significantly at P≤0.05 in the liver of uninfected fish. On the other hands, there were no significant different in liver AST activity between the infected and the uninfected fish. There were significant differences at P≤0.05 between activities of the three enzymes in both infected and uninfected fish and tapeworm tissues. On the other hands, AST activity 35.46 IU/L was relatively higher than ALT activity 27.22 IU/L in tapeworm tissues. It is concluded that activitiesofliver LDH and ALT were significantly affected by intestinal tapeworm infection in Hekle fish and may considered as bioindicators for tapeworm infection in fish.

The current study aimed to investigate the effect of garlic juice supplementation with broiler drinking water on performance, immune response, lipid profile, blood picture and activity of liver enzymes under heat stress. For this purpose 100 four days aged broiler checks (Ross) were allocated into control (C) and three treatment groups (25 each). All group checks were housed at 5 ºC above normal ambient temperature during the experiment. Treatment groups (T1, T2 and T3) checks were supplemented with 0.5, 1 and 1.5 ml/L, respectively, with garlic juice in drinking water (6 hrs a day). Food and water were supplemented ad libitum. Body weights were monitored every five days and blood samples were obtained at 25 days for assessment of blood picture and antibody titers after vaccination, total cholesterol and triglycerides concentrations and activity levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP) were estimated. At 30 days age, T3 group broiler checks reported higher body weights than other groups. Total number of white and red blood cells, hemoglobin concentration, hematocrit levels and ratio of heterocytes to lymphocytes increased significantly in treated groups, whereas significant decline of cholesterol and triglycerides concentrations as well as ALT and AST levels were shown in T3 group broiler checks. Significant increase was shown in the levels of antibody titers against both Newcastle (ND) and infectious bursal disease (IBD) vaccines. In conclusion, treatment of broiler checks early with garlic juice increase broiler performance and immune response against vaccination program and may be protect the broilers from heat stress.
