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.

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.

RESUMO: No intuito de contribuir para um desenvolvimento agrícola e pecuário sustentável no estado de Goiás, este artigo analisa as áreas prioritárias para a recuperação de pastagens no vale do Araguaia, uma região especializada nesta atividade. Para tanto, foram utilizadas as seguintes variáveis: mapa de degradação de pastagens (plataforma Pastagem.org), aptidão agrícola e vulnerabilidade ambiental, requisitos analisados em conjunto em um Sistema de Informações Geográficas. Nossos resultados indicam a existência de mais de 460 mil hectares de pastagem aptos à reforma ou recuperação, podendo gerar um incremento de mais de 2,6 milhões arrobas de proteína bovina. Por ser uma das maiores regiões pecuárias do país e de seu rebanho se alimentar primordialmente de pastagens cultivadas, a recuperação destas se mostra crucial ambiental e economicamente. DEFINITION OF PRIORITY AREAS FOR THE RECOVERY OF DEGRADED PASTURES AND THEIR ECONOMIC IMPACT IN THE ARAGUAIA VALLEY, GOIÁS STATE ABSTRACT: To contribute to sustainable agricultural and livestock development in the state of Goiás, this article analyzes the priority areas for the recovery of pastures in the Araguaia valley, a region specialized in this activity in Brazil (Cerrado biome). For that, the following variables were used: pasture degradation map (Pastagem.org), agricultural aptitude and environmental vulnerability,requirements analyzed together in a Geographic Information System. Our results indicate the existence of more than 460 thousand hectares of pasture suitable for reform or recovery, which may generate an increase of more than 2,6 million arrobas of bovine protein. As it is one of the largest livestock regions in the country and its herd feeds primarily on cultivated pastures, their recovery is crucial in environmental and economic terms.
