Abstract: The use of the CIDR (controlled internal drug release) dispenser as a progestagen-synchronizing agent was evaluated in 37 Karakul ewes during the breeding season, using the intravaginal progestagen sponge as a control (30 ewes). Although there was no significant differences in oestrous response, following intravaginal insertion for 14 days, between these two progestagen devices, the time from device withdrawal to the onset of the induced oestrous period (31,2 vs 62,5 h) and the duration of the induced oestrous period (32,7 vs 47,4 h) was significantly (P<0,01) shorter in the CIDR dispenser group. The mean time from device withdrawal to the serum preovulatory LH peak and the interval from the onset of oestrus to the pre-ovulatory LH peak was significantly (P<0,01) earlier in the CIDR dispenser group (28,0 vs 78,0 hand 5,3 vs 17,3 h respectively). No significant difference in the serum progesterone concentrations was noted between the two groups. No significant difference in reproductive performance was obtained with conception, lambing rates and fecundities of 72,2 vs 79,3%; 75,0 vs 89% and 103,8 vs 113,0% for the dispenser and sponge treatment groups respectively. Results confirm the potential of the CIDR dispenser as an efficient synchronizing agent and the more concentrated synchrony obtained makes it ideal for fixed-time insemination.

Alhoewel daar geen betekenisvolle verskil in estrusrespons na intravaginale toediening vir 14 dae tussen die twee progestogeenbehandelings was nie, was die tydsduur vanaf die einde van behandeling tot die aanvang van estrus (31,2 vs 62,5 h) en die tydsduur van die gei'nduseerde estrusperiode (32,7 vs 47,4 h) betekenisvol (P<O,Ol) korter in die CIDR-dispensorgroep. Die gemiddelde tydsduur vanaf onttrekking tot die voor-ovulasie LH-piek en die interval vanaf die aanvang van estrus en die voor-ovulasie LH-piek was betekenisvol (P<0,01) vroeer in die CIDR-dispensorgroep (28,0 vs 78,0 h en 5,3 vs 17,3 h respektiewelik). Geen betekenisvolle verskil in die serum-progesteroonkonsentrasies is waargeneem tussen die twee groepe nie. Geen betekenisvolle verskil in vrugbaarheidsresultate is verkry met konsepsie, lampersentasie en fekunditeite van 72,2 vs 79,3%; 75,0 vs 89,7% en 103,8 vs 113,0% vir die CIDR-dispensor- en sponsbehandelingsgroepe respektiewelik. Resultate dui op die potensiaal van die CIDR-dispensor as 'n effektiewe sinkronisasiemiddel en die meer gekonsentreerde sinkronisasie verkry, maak dit ideaal vir uitvoering van KI op 'n vasgestelde tyd.

Le Brésil a initié deux politiques publiques territoriales pour le développement rural durable, le Programme National pour le Développement Durable des Territoires Ruraux (PRONAT) et le programme territoires de la Citoyenneté. Ces politiques s'appliquent dans des Territoires Ruraux et visent à re-équilibrer les rapports de forces entre les acteurs au sein de la Collégialité pour le Développment territorial (CODETER) de chaque Territoire Rural. Notre recherche étudie l'hypothèse selon laquelle, dans les Territoires Ruraux soumis aux politiques publiques PRONAT et PTC, les rapports de pouvoir et de réciprocité entre les acteurs engagés dans les CODETER ont effectivement évolué, en faveur des représentants de la société civile et au détriment des pouvoirs publics établis, notamment les mairies. Cette recherche a développé une méthode de modélisation et de simulation des relations de pouvoir et de réciprocité au sein des entités territoriales. À partir de l'étude des modèles nous pouvons affirmer que les politiques à un nouvel équilibri des rapports de forces entre la société civile et les pouvoirs publics. |
