(1998-12-01)
Differences in culture duration, metamorphosis rate and the productivity in hatchery culture of M. rosenbergii using a closed system with natural and artificial brackish water were evaluated. Reuse of brackish water in ...
Fuzzy modeling to predict chicken egg hatchability in commercial hatchery
(Poultry Science Assoc Inc, 2012-10-01)
Experimental studies have shown that hatching rate depends, among other factors, on the main physical characteristics of the eggs. The physical parameters used in our work were egg weight, eggshell thickness, egg sphericity, ...
Heat loss of fertile eggs on the road between the hatchery and hatcher
(2016-01-01)
The microenvironment around the fertile egg on incubation process can influence the development of the embryo and reflect on the hatching rate in the post-hatching performance, and also the quality of the hatched chicks. ...
