title: Insulin and glucagon secretory patterns during propionate and arginine tolerance tests in Japanese black cattle with growth retardation.
abstract: To evaluate the energy condition of cattle with growth retardation, propionate (PTT) and arginine tolerance tests (ATT) were carried out. The insulin/glucagon concentration ratio immediately before PTT or ATT in the cattle with growth retardation was lower than in the control. In the growth-retarded cattle, insulin-AUC(0-120 min) during PTT was lower than in the control, while glucagon-AUC(0-120 min) was the same as in the control. Insulin-AUC(0-120 min) during ATT in the cattle with growth retardation tended to be lower than in the control, whereas glucagon-AUC(0-120 min) was the same. Therefore, insulin-AUC(0-120 min)/glucagon-AUC(0-120 min) in the cattle with growth retardation was lower than in the control during both tolerance tests. The growth-retarded cattle showed lower insulin/glucagon ratio similar to that found in starved and lactating cattle, suggesting a lack of energy.
