Abstract: A veterinary pharmaceutical composition, including at least one active veterinary pharmaceutical substance which is selected among gonadorelin and gonadorelin analogs as well as salts of gonadorelin and of the gonadorelin analogs, is provided. The composition includes a liposome-free matrix which delays the release of the active veterinary pharmaceutical substance from the composition, which matrix includes a basic material which is selected from the group consisting of natural and synthetic triglycerides, vegetable oils, diacylpropanediols, diacylbutanediols and mixtures of these substances, the veterinary pharmaceutical composition including no biodegradable polymer.

Abstract: A method for inducing the onset of the reproductive cycle of female breeding animals is provided. To this end, the animals are injected with an agent that contains synthetically produced FSH releasing hormones as the active substance which comprise known sequences, consisting of 10 amino acids (decapeptide). The active substances are administered to the animals in the form of solution 0 to 96 hours after termination of the preceding anestrus or inhibition or a biotechnical treatment. The agents used promote an onset of the reproductive cycle after the young animals have been weaned from the mature animals and a synchronization of heat in animals that are to be inseminated for the first time.
