EFFECT OF FORCE-FEEDING ONFATTY LIVER AND SERUM BIOCHEMICAL PARAMETERS IN MULE DUCKS

Abstract

A study on the changes of body weight, liver and blood serum biochemical parameters - L-aspartat-2-oxoglutarat aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamyltransferase, total cholesterol, triglycerides and creatinine of male and female mule ducks before and after force-feeding was carried out. The forcefeeding of ducks with maize was taken after 74-days of age and continued 13 days. During force-feeding period, the body weight increased with 47.25% in males (from 3983±133.85 g to 5865±212.33 g) and with 38.06% in female ducks (from 3450±215.06 g to 4763±87.73 g). The liver weight increased 7.53 times in males (from 82±5.40 g to 600±22.86 g) and 5.65 times in females (from 77±4.81 g to 435±46.79 g). After 13 days of force-feeding significantly increased the blood serum concentration of alanine aminotransferase (P<0.05 in males and P<0.01 in females), total cholesterol (P<0.001 in both sexes) and triglycerides (P<0.001 in both sexes), and decreased of γ-glutamyltransferase (P<0.01 in males and P<0.05 in females), and creatinine (P<0.01 in males and P<0.001 in females).
