Development of an injection molded ethylene-vinyl acetate copolymer (EVA) intravaginal insert for the delivery of progesterone to cattle
(Elsevier Science, 2015-05)
The purpose of this study was to develop a new injection-molded intravaginal insert man-ufactured from ethylene-vinyl acetate containing progesterone for a 7-day insertion periodin cattle. The manufacturing process resulted ...
Hormonal changes and follicular activity after treatment with intravaginal progesterone-releasing devices in llamas
(Wiley Blackwell Publishing, Inc, 2016-12)
Plasma progesterone (P4) concentrations and follicular activity after administration of different P4 doses were evaluated in 33 adult female llamas treated with intravaginal devices. In Study 1, a group of llamas (n = 10) ...
Strategies to improve fertility in postpartum multiparous Bos indicus cows submitted to a fixed-time insemination protocol with gonadotropin-releasing hormone and prostaglandin F-2 alpha
(Amer Soc Animal Science, 2009-09-01)
In Exp. 1, we evaluated the effects of 2 lengths of progesterone exposure [CIDR (controlled intravaginal drug release); 7 vs. 14 d] before a modified CO-Synch protocol [50.0-mu g injection of GnRH 6.5 d before a 25.0-mg ...
Design and evaluation of a recyclable intravaginal device made of ethylene vinyl acetate copolymer for bovine estrus synchronization
(Springer, 2020-01)
In bovine estrus synchronization, intravaginal devices made of silicone are used to administer exogenous progesterone with the aim ofmaintain plasmatic levels above 2 ng ml−1 during the treatment. After their use, devices ...
Autoclaved, previously used intravaginal progesterone devices induces estrus and ovulation in anestrous Toggenburg goats
(Elsevier B.V., 2011-11-01)
Intravaginal progesterone devices are used worldwide for estrus induction in goats. Reused devices are able to induce estrus; however, this can be a health risk within a flock. The objective was to compare new and previously ...
