폭염 하에서 음수 내 비타민 C와 트리메칠글리신 공급이 오리의 혈액 매개변수 및 생산성에 미치는 효과

초록

The objective of this study was to determine the effect of drinking water containingtrimethyl glycine or ascorbic acid on growth performance and blood parameter profiles of duckexposed to scorching heat stress. A total of 480 ducks were randomly assigned to the followingeight experiment groups for 42 days : control group C with general water, treatment group 1 (T1)with drinking water containing 100 ppm ascorbic acid, treatment group 2 (T2) with drinkingwater containing 200 ppm ascorbic acid, treatment group 3 (T3) with drinking water containing300 ppm ascorbic acid, treatment group 4 (T4) with drinking water containing 400 ppm trimethylglycine, treatment group 5 (T5) with drinking water containing 800 ppm trimethyl glycine,treatment group 6 (T6) with drinking water containing 1,200 ppm trimethyl glycine, treatmentgroup 7 (T7) with electrolytes of KCl (0.5%) + NaHCO3 (1.0%)+NaCl (0.5%). Our resultsrevealed that the body weights and feed intakes of treatment groups, especially T3 and T6, wereincreased compared to the control group, where as the feed conversion ratios of treatment groupswere decreased (p<0.05). Blood levels of total cholesterol, triglyceride, LDL-C, glucose, AST, ALTand pH in treatment groups were lower compared to those in the control group (p<0.05). Bloodlevels of red blood cell, platelets profiles, electrolyte and gas in treatment groups were highercompared to those of the control group (p<0.05).
