Özet
The aim of this study was to evaluate the effect of diet supplemented with L-arginine (L-Arg)on growth performance, some serum biochemical parameters and duodenal motility of broilers during three time periods: 0 to 10, 11 to 28 and 29 to 42 days old. A total of 500, mixed sex, one-day-old Ross-308 broiler chicks were divided into five groups as follows: Arg deficient group and four experimental groups. Each group was then divided into five subgroups of 20 chicks each. Arg deficient group for all time periods was fed by basal diet which contained 10% less L-Arg than optimum Arg requirement recommended by the breeder. Experimental groups were fed by basal diet supplemented with L-Arg which was progressively 10% increased in groups. The highest body weight gain (BWG) was observed on days 11-28 and 0-42 in experimental group fed by basal diet supplemented with 110% L-Arg, whereas the lowest feed conversion ratio (FCR) was determined on days 29-42 and 0-42 in the same experimental group. Feed intake did not change in all three periods, while serum urea nitrogen level in the experimental group in which diet supplemented with 10% L-Arg, was lower than other groups on day 0-10. On contractility studies, it was observed that L-Arg inhibited the amplitude of contractions in duodenum in a dose-dependent manner in vitro. These results suggest that the basal diet formulated with 90-130% Arg is not effective on growth performance of chicks on days 0-10, whereas the diet supplemented with 10% L-Arg more than optimum Arg requirement is adequate during the days 11-28 and 29-42. Moreover, although the L-Arg decreased the duodenal contractility in vitro, it is suggested that the diet supplemented with 10% L-Arg more than optimum Arg requirement may be negatively affected the FCR in broilers.
