Eficiência da eclodibilidade de incubadoras artificiais

Abstract

The experiment was carried out with the objective of evaluating the efficiency of hatchability in the models of hatcheries produced by hand. Low-cost and efficient materials that achieve good hatch rates were sought. Three brooders, 1 styrofoam (A) and 2 wood (B1) and (B2) were elaborated to test the hatchability efficiency. Two experiments were carried out at different periods. A total of 80 quail eggs were obtained, in the experiment I incubated 20 units in each model (A and B1), in the model (A) we obtained 11 eggs from the 20 incubated, in the brooder (B1) there was no hatching, but the temperature variable (B1) had large dimensions for the quantity of eggs introduced, it is possible to observe the delay of the heating in the interior during the experiment, there was then a need to redo the wood model (B2) in reduced dimensions, since factors such as ventilation, so that CO2 accumulation did not lead to the death of the embryo, and the egg turning for oxygen availability, were performed in a suitable way in the two models tested. In the second experiment, 20 eggs were used in each model (A and B2), the brooder (A) of the 20 eggs incubated or the hatching of 18 eggs, in the brooder (B2) 14 of the 20 eggs hatched. The models in question showed efficiency, but styrofoam (A), in both experiments presented higher indices in relation to the wooden brooder, but its construction is simple and if used correctly can be a good investment.
