The aim of this study was to evaluate interrelationships of body weight and bone weight and densitometric properties of the tibiotarsus in White Koluda Geese (W31) in the post-hatching period. The stu...
The influence of cadmium (Cd) on the last stage of Prussian carp (Carassius auratus gibelio B.) oocyte maturation and embryonic development was investigated. The (postvitellogenic) oocytes were incuba...
We examined the effect of orally administered L-carnitine (at a dose of 30 mg per kg of feeding mixture) on egg hatching and some haematological and biochemical parameters of blood plasma in COBB 500 ...
This study investigates, in red-legged partridge (Alectoris rufa), the effects of the time to change from incubation to hatching temperature on egg weight loss, hatchability, chick weight at hatch, in...
Dormant eggs of zooplankton are considered to be tolerant of harsh environmental conditions, yet lethal thresholds of exposure have rarely been determined. We describe 3 yr of dose–response experimen...
To test the hypothesis that variation in hatching and survival of Daphnia dormant eggs is fostered by genetic differences among populations, rather than system-specific availability of environmental ...
The objective of this study was to determine if the bore diameter of needles used for in ovo injection of amino acids (AA) would affect subsequent chick hatchability. In Experiment 1, needles of diffe...
Non-coliform gram-negative bacteria like Salmonella, pseudomonas and proteus are the causes of yolk sac infection. In this study, we evaluated the effect of formaldehyde on the reduction rate of egg s...
The purpose of the present study was to establish the effect of the prolonged storage of Japanese quail hatching eggs upon the incubation performance and the quality of hatched quail chicks. The durat...
In this study, we conducted various experiments in order to develop enhanced cultural conditions for in vitro-produced porcine embryos. All embryos were produced by in vitro maturation (IVM) and ferti...
This paper provides information on the relation of abiotic factors (moisture content, nest depth, distance of nest from the sea and distance from vegetation) and a biotic factor (clutch size) with the...
The effects of dark-control (D) and continuous green light (GL) exposure of incubated meat-type breeder eggs (Hybro) on embryonic growth from 5 to 15 days of age, hatching time, hatchability per cent ...
