Physical quality of different industrial versus non-industrial eggs obtained from groceries and markets in southern Chile
(Faculty of Veterinary Sciences - Universidad Austral de Chile, 2023)
Genetic analysis of female reproduction traits of fanned coho salmon (oncorhyncus kisutch)
(ELSEVIER SCIENCE BV, 2004)
Based on 8 years of data on 891 daughters from 190 sires and 398 dams, females produced an average (standard deviation) of 4251 (957) green eggs with a total weight of about 680 (191) g; the females produced 3226 (1255) ...
Mortality, production and quality of eggs of different rearing systems
(2018-07-01)
The conventional production of eggs in cage systems is intense and compromises the laying hens welfare. More demanding consumer markets have been pushing to abolish the use of cages and thus provide better welfare in poultry ...
Modelling the egg components and laying patterns of broiler breeder hens
(2016-01-01)
There is scant information about the reproductive process in broiler breeders, with which to develop a feeding strategy that will be economically optimal for these birds. This study aimed to model the egg production of a ...
Egg production in relation to paternal weight in a freshwater caridean shrimp (Decapoda)
(Wiley Blackwell Publishing, Inc, 2019-04)
In diverse invertebrate species, sperm quantity and quality are positively correlated with male size, egg fertilization rates being consequently affected by paternal weight. This factor may also have an indirect effect on ...
Effects of Ascorbic Acid Injection in Incubated Eggs Submitted to Heat Stress on Incubation Parameters and Chick Quality
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2015-04-01)
Dose-dependent positive effects on hatchability and hatchling weight have been attributed to ascorbic acid (AA) when eggs were submitted or not to intermittent heat stress during incubation. Fertile breeder (Cobb (R)) eggs ...
Genetic parameters of body weight and egg traits in meat-type quail
(Livestock Science, 2018)
Methods to evaluate the eggshell quality of table eggs
(2019-01-01)
The objectives of this study were to determine the most suitable probe diameter and egg position to perform the eggshell breaking strength test using a texturometer, as well as the most reliable parameter to estimate ...
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. ...
Rhodocyclus gelatinosus biomass for egg yolk pigmentation
(Poultry Science Assoc Inc, 2004-09-01)
Biomass of the photosynthetic bacterium Rhodocyclus gelatinosus was used at different levels in laying hens' rations as a xanthophyll source. Sixty-four hens were used in the experiment that investigated the effects of ...
