Influence of Oxygen Concentration on Hatchability and on Selecting for Hatchability , ,
Poultry Science, 1955 Abstract OBTAINING a respectable hatching percentage from the eggs of domestic poultry is one of the important problems of the poultry industry in areas of high elevation. This problem exists at Laramie, Wyoming, where the elevation is approximately 7,200 feet above sea level. The Wyoming Agricultural Experiment Station, highest in the United States,

Influence of eggshell ultrastructural organization on hatchability
Poultry Science, 2013 Eggshell quality is associated with hatchability, and ultrastructural organization is an important eggshell quality parameter. To the determine the relationship of shell ultrastructural properties with hatchability, we measured the effect of eggshell thickness, mammillary layer thickness, and the average size of mammillary cones on hatchability.

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Suitability of calorie fortified diets for improving the production of Clarias gariepinus broodstock and fry [PDF]
, 1993 The findings are presented of an experiment conducted to determine the adequate level of calorie in diets that is necessary to bring Clarias gariepinus female broodstock to grand stage. The effect of different calorie level on the quality and quantity of

Successful handstripping of hatchery bred and reared male African catfish, Clarias gariepinus (Burchell, 1822) [PDF]
, 1999 A total of 45 Male and 5 female Clarias gariepinus bred and reared in the hatchery in sunning for one year were obtained for this experiment. The fish were then housed separately according to their sexes and maintained on trout diet at 10% body weight ...
