Intravaginal progestagen for estrus and parturition control in sows Repositório Alice
GASPERIN, B.G.; FRELING, G.F.; FERREIRA, R.; OLIVEIRA, J.F.C. de; BORDIGNON, V.; GONÇALVES, P.B.D..
The objective of this work was to evaluate the use of intravaginal devices (IVD) for the control of reproductive events in swine. Sows at 112 days of pregnancy received an injection of PGF2á (control, n = 15) or PGF2á plus an IVD containing medroxyprogesterone acetate (IVD group, n = 14) for 48 hours. Sows initiated labor 27.7±1.6 and 82.3±3.8 h after PGF2á aplicaction, in control and treated groups, respectively. Regarding control of estrus cycle, ten sows received IVD for 12 days starting immediately after weaning, and estrus was confirmed 17.25±0.17 days after weaning, in comparison to 4.00±0.25 days for the control group. Intravaginal devices with progestagen can be applied for the control of reproduction in swine.

Prepartum progestagen supplementation in swine: a strategy to facilitate piglet care and prevent early parturition Ciência Rural
Haas,Cristina Sangoi; Santos,Monike Quirino dos; Rovani,Monique Tomazele; Santos,Joabel Tonellotto dos; Mellagi,Ana Paula Gonçalves; Bortolozzo,Fernando Pandolfo; Gasperin,Bernardo Garziera; Gonçalves,Paulo Bayard Dias.
ABSTRACT: Gestation length in swine has a considerable amplitude and both early and delayed parturition are common. This variation increases the occurrence of unassisted farrowing and could lead to a wide-ranging age at weaning for piglets born from one batch. Supervision of sow parturition is crucial to reduce mortality of neonate piglets. To facilitate assistance, induction of farrowing using prostaglandin F2α (PGF) has been widely used in batch farrowing systems, whereby synchronization would concentrate the time of farrowing, allowing for better organization of employees. However, a viable alternative method that can be implemented to manage farrowing is to sustain high progestagen levels in the final days of gestation and, consequently, prevent early...

Qualitative and quantitative analysis of bacteria from vaginitis associated with intravaginal implants in ewes following estrus synchronization Ciência Rural
Vasconcelos,Carlos Otávio de Paula; Brandão,Felipe Zandonadi; Martins,Gabriel; Penna,Bruno; Souza-Fabjan,Joanna Maria Gonçalves de; Lilenbaum,Walter.
ABSTRACT: This study evaluated the presence of vaginitis and the bacterial load associated with different intravaginal implants in ewes. Twenty-four Dorper and crossbred ewes were allocated into three groups and received intravaginal implant containing 0.3g progesterone (CIDR(r)), 60mg MAP or sponges without progesterone (CONTROL) for six days. Then, CIDR and MAP treated-ewes received 12.5mg dinoprost and 300IU eCG. Vaginal mucus samples were collected at four times: before device insertion, at the day of its removal, 24 and 48 hours after. The samples were cultured and the colonies were counted (CFU/mL) and identified. The results obtained from the counting of CFU mL-1 were submitted to Kruskal-Wallis H test, with P<0.05 being considered significant....
