Última Manejo reproductivo postparto en ovejas de pelo. Colegio de Postgraduados Castillo Maldonado, Paulina Paola. En este estudio se evaluó el efecto del amamantamiento y un protocolo de sincronización postparto (PP) con el efecto del carnero y destete temporal en la respuesta reproductiva de las ovejas de pelo. Aisladas de los carneros dos meses antes de la sincronización, 96 ovejas fueron clasificadas aleatoriamente al parto en dos grupos (n=48): amamantamiento continuo por 18 horas (Ac) y lactancia controlada con amamantamiento por 30 min 2 veces día-1 (Lc). En el día 35 PP las ovejas se sincronizaron con CIDR por 10 días; y 48 horas antes de retirarlo se les aplicó 7.5 mg de dinoprost y se probó el efecto del carnero (Ca) y el destete temporal (Dt). Se determinó el contenido de progesterona plasmática (P4) por RIA a los 30, 35, 50, 55 y 64 días PP. Las ovejas...

Ano: 2012 URL: http://hdl.handle.net/10521/1092 Evaluating Regulatory Impact Analyses AgEcon Harrington, Winston; Morgenstern, Richard D.. Federal agencies in the United States are required to prepare regulatory impact analyses (RIAs) for every major regulatory action they undertake. Increasingly, other OECD countries are imposing similar requirements. However, there has been little examination of the quality of these documents or of the uses to which they have been put in the regulatory process or elsewhere. In this paper we survey previous efforts to evaluate RIAs and find a fair amount of evaluation of RIAs as stand-alone documents, but much less evaluation of their contribution to producing better regulations.

Ano: 2004 URL: http://purl.umn.edu/10774 Correlation between sperm characteristics and testosterone in bovine seminal plasma by direct radioimmunoassay R. Bras. Zootec. Souza,Luiz Waldemar de Oliveira; Andrade,André Furugen Cesar; Celeghini,Eneiva Carla Carvalho; Negrão,João Alberto; Arruda,Rubens Paes de. The objectives of this study were to validate a non-extractive RIA for seminal testosterone and quantify the hormone using a solid-phase commercial kit, and study the correlation between testosterone in seminal plasma and sperm characteristics. Parallelism showed a correlation index r = 0.992 (Y = -5.47 + 1.073X; R² = 0.985), indicating that the non-extractive method presented is indicated particularly for assessment of testosterone when establishing comparisons between samples. Overall mean (±SD) of testosterone level was 0.60±0.65 ng/mL. Correlation was only found between the seminal concentrations of testosterone and pH of the semen.
