High Quality good supplier 850-52-2 Altrenogest in stock CAS NO.850-52-2

Altrenogest is a progestin of the 19-nortestosterone group. As a veterinary medication, it is used extensively in the reproductive management of mares to control the reproductive cycle, help maintain pregnancy, and help with behavior modification. Altrenogest has been demonstrated to maintain pregnancy in oophorectomized mares and may be of benefit in mares that abort due to subtherapeutic progestin levels. Altrenogest is typically administered orally by applying directly on the base of the mare’s tongue or on the mare’s feed.

Altrenogest (Allyltrenbolone) is a progestogen structurally related to veterinary steroid trenbolone. Treatment of embryo-recipient mares with Altrenogest (Allyltrenbolone) appears to be beneficial in extending the degree of donor-recipient synchrony required for successful embryo transfer. The oil and gel Altrenogest (Allyltrenbolone) preparations are equally effective in modulating estrous behavior and time to estrus and ovulation. Altrenogest (Allyltrenbolone) treatment started late in diestrus appears to result in a high incidence of ovulation during treatment and when luteolysis and ovulation occur during treatment; the subsequent luteal phase is frequently prolonged due to failure of regression of the CL.

Altrenogest is effective in normally cycling mares for minimizing the necessity for estrus detection, for the synchronization of estrus, and permitting scheduled breeding. Estrus will ensue 2 – 5 days after treatment is completed and most mares ovulate between 8 – 15 days after withdrawal. Altrenogest is also effective in suppressing estrus expression in show mares or mares to be raced. Although the drug is labeled as contraindicated during pregnancy, it has been demonstrated to maintain pregnancy in oophorectomized mares and may be of benefit in mares that abort due to sub-therapeutic progestin levels.

The product Matrix is labeled for synchronization of estrus in sexually mature gilts that have had at least one estrous cycle. Treatment with altrenogest results in estrus (standing heat) 4-9 days after completion of the 14-day treatment period.
