The use of Cloprostenol and prostaglandin F2alpha to induce luteolysis in reindeer calves (Rangifer tarandus)
AbstractA total of 126 reindeer of about 7 months of age, were isolated from a flock at the end of the breeding season. The animals were treated either with 12.5 mg prostaglandin F2alpha (n = 41) or 0.25 mg cloprostenol (n = 50). Thirty-five animals were left untreated. Blood samples were collected before treatment and 2 Vi days later and the plasma progesterone concentrations were determined. A significant fall in progesterone concentration was seen in both treatment groups. A large proportion of animals responded to treatment with cloprostenol than with prostaglandin F2alpha. It was concluded that prostaglandins can be used to induce luteolysis in reindeer.
