During the cooling process of embryonated eggs, there is a natural air flux from the surface to the inner part of the eggs, carrying contaminants such as bacteria and fungi through the shell's pores, infecting embryos and resulting in the inability to hatch or poor chick quality.

Introduction: Egg quality and its components are important indices to consumers, and the economic success of producers depend on the total number of eggs sold. Egg quality is based on the characteristics of the eggs that affect its acceptability, and the egg components are of nutritional importance. Therefore, the study was carried out to determine the chemical and mineral compositions of ostrich eggs found in southern guinea savannah environ of Nigeria. Methods: Eighty freshly laid eggs were obtained from Ostrich birds in Old Oyo National Park and were used for the experiments. Data were obta

Abstract Stocking with eggs has been widely used as a management measure to support degraded salmonid stocks. In Finland, Atlantic salmon and both sea-migrating and lake-migrating brown trout are stocked as eggs, alevins, fry, parr, and smolt, whereas trout are also stocked as mature fish. The aim of this stocking is to improve catches and to support collapsed spawning stocks. We assessed the success of stocking with brown trout eggs in a study of 17 Finnish boreal forest rivers, of which 9 were subject to egg stocking. All rivers contained some naturally spawning trout.

Additionally, strains within a species can exhibit differential susceptibility to formalin.

The cestode Schistocephalus solidus is a simultaneous hermaphrodite that grows in 2 intermediate hosts and reproduces rapidly within a few days in the gut of a bird.

Egg production in an in vitro system was found to depend on the cestodes' social situation. When kept alone, larger cestodes produced larger eggs. This was not so when kept in pairs – the difference between these 2 reproductive modes b
