Effect of organic selenium and zinc on the performance and egg quality of Japanese quails
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2011-06-01)
The present study aimed at evaluating the effect of the dietary inclusion of organic trace minerals selenium and zinc on the performance and internal and external egg quality of Japanese quails submitted to heat stress. ...
Bioinsecticide action of the venom of Africanized bees Apis mellifera Linnaeus 1758 (Hymenoptera: Apidae): I - The most susceptible age of Diatraea saccharalis Fabricius 1794 (Lepeletier: Pyralidae) eggs to the venom action
(1996-01-01)
The present paper aimed at testing the action of non-lyophilized venom of Africanized bees Apis mellifera through topical applications on Diatraea saccharalis egg masses. The CL50, DL50 and the most susceptible age of eggs ...
Correlations between thermal environment and egg quality of two layer commercial strains
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2008-06-01)
