Abstract

The objective of this paper was to test three different protocols for DNA extraction regarding the extraction efficiency, quantity, quality of DNA extracted and extraction cost. Animals were from a farm in Rio de Janeiro state. Feathers samples of free-range chickens were collected from pectoral and blood samples were collected from brachial vein. The protocols tested were: 1) Rapid alkaline extraction from total blood collect; 2) Rapid alkaline extraction from feathers bulb of pectoral; and 3) DNA extraction with blood commercial kit (Nucleo Spin® Tissue) in FTA Card (NucleoCard). After the extraction, samples were quantified e the concentration and quality of DNA were verified in all protocols, using spectrophotometry. The protocols 1 and 2 had good result in the amount of DNA extracted, but they had high concentration of proteins. Protocol 3 had low amount of DNA extracted, but it has high purity. All protocols had good results in relation to the quality of amplification, although, protocols 1 and 2 of alkaline extraction had more facility to use, higher speed in extraction and lower cost than protocol 3.
