Study On The Self-made Sponges With Progestongen For Deer

Fluffy deer mainly refers to wapiti and sika deer, two deer are submit deer subfamily (Cervinae), a deer (Cervus). Because of its seasonal estrus and characteristics of single births, new requirements in the process of rearing its breeding work, and the current number of livestock reproductive technology for the efficient breeding deer has provided a new opportunity, which the estrus synchronization is one of them.In the beginning of the 20th century for the 60 clinical Fluoride progesterone vaginal suppository sponge was has been induced by cattle and sheep to become the preferred method of estrus abroad. Improve reproductive rate and induce superovulation, etc.. So far, this has been progesterone products in the United States, Ireland, Canada, France, the United Kingdom, Australia, the Netherlands, and animal husbandry developed countries widely used. In recent years, some countries due to the rise of Deer Industry, is gradually applied to the breeding of deer.Test in the breeding season and pre-season use of different types of vaginal suppository to induce or deer for estrus synchronization test, designed to reduce Selt-made sponge with progesterone costs and improve the effectiveness of their estrus synchronization, so that the products can be in production in deer been widely applied.Test respectively in the following areas: different seasons vaginal suppository estrus effect, pre-breeding season PMSG injection dose and time, Selt-made sponge in different periods progesterone suppository content and implants, vaginal embolization estrus synchronization results, the natural estrus synchronization of estrus with the same period of comparison, the rate of twins, the different methods of estrus synchronization cost comparison of test results show that:1 Selt-made sponge with progesterone deal with the same period with imports CIDR estrus synchronization can advance the breeding season, conducive to the growth and the postpartum resume.2.In the breeding season selt-made sponge with progesterone 40 mg, 12-14d dismantling have the best effect. before breeding season, 7-9d dismantling PMSG 600IU injection have the best effect.3. Selt-made sponge with progesterone have good effects in produce deer and raise deer (P > 0.05 ) artificial induction estrus significantly enhanced the twins pregnancy (P < 0.05 ).4. Selt-made sponge with progesterone is a low-cost, good heat effect estrus synchronization suppository products with CIDR (P > 0.05 ).
