Effects of L-carnitine administration on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks

Abstract

Effects of L-carnitine administration via drinking water on growth performance, carcass traits, blood serum parameters and abdominal fatty acid composition of ducks was examined. One hundred day-old Turkish native duck chicks were divided into two groups, each with five replicates and given the same diets with 0 and 200 mg/l carnitine chlorhydrate via drinking water. The study lasted 8 weeks, with the first 4 weeks as a starter and the last 4 weeks as grower period. At the end of the study five ducks were randomly selected from each subgroup for slaughter. Growth performance parameters of ducks were not affected significantly by L-carnitine administration. Live weight, daily weight gain, cumulative feed consumption and average feed conversion efficiency were found to be 1490 and 1621 g, 26.0 and 28.1 g, 5386 and 5662 g, 3.75 and 3.54 kg/kg in the control and in the carnitine groups respectively. L-carnitine administration did not effect carcass traits and serum cholesterol, total lipid, triglyceride and glucose levels. Total saturated fatty acid content of abdominal fat significantly decreased, mono- and polyunsaturated fatty acid content were not affected by L-carnitine administration. In conclusion, L-carnitine administration by drinking water did not affect growth performance, carcass traits and blood parameters in ducks.

Effects of housing system, slaughter age, and sex on slaughter and carcass traits of native Turkish ducks

“…The feed conversion efficiency at the eighth week and in the range of 0-8 weeks in the cage system were 6.84 and 4.48 kg, respectively. These results were in agreement with the reports by Arslan et al (15) for native Turkish ducks raised on a fattening platform. Feed conversion ratio was better in the deep litter floor system than in the cage system.…”

“…The effects of housing system, sex, and slaughter age on hot carcass, cold carcass, leg, breast, wing, neck, and back percentages. carcass percentages for males and females (65.96% and 64.65%, respectively) at 8 weeks of age in cage systems were similar to those given by Arslan et al (15), who reported hot carcass percentages of control and carnitinefed groups (63.60% and 65.90%, respectively) at 8 weeks of age in native Turkish ducks raised on a fattening platform. Moreover, in the present study the hot carcass percentages in the cage system (68.98%) and deep litter floor system (67.06%) at 10 weeks of age for male ducks were found to be similar to those reported by Laçin and Aras (7), who showed hot carcass percentages at 10 weeks of age for male Pekin ducks in duck-fish integration groups (69.90%), in nonintegrated groups with ducks raised only in ponds without fish (68.90%), and in poultry house conditions (69.10%) with ducks raised without fish or ponds.…”

“…In the present study, the slaughter weights for males and females (1763 and 1660 g, respectively) at 8 weeks of age in the cage system were similar to those given by Arslan et al (15), who reported slaughter weights of carnitine-fed and control groups (1750 and 1653 g, respectively) at 8 weeks of age in native Turkish ducks raised on a fattening platform. Slaughter weights observed in the present study were, however, lower than those reported by Sarı et al (18) in native Turkish ducks.…”

Effect of L-carnitine supplementation on drake semen quality

“…L-Carnitine (β-hydroxy-γ-trimethylammonium butyrate) is a highly polar natural compound found in microorganisms, plants and animals (Arslan et al, 2003). It has been shown to have beneficial effects on the heart and skeletal muscles, and conditions such as disorders of the central nervous system, certain types of male sterility and some disorders in newborns (Benvenga et.…”
