Five hundred ten duck eggs of Pekin and each of Muscovy duck eggs were incubated to determine fertility and hatchability. The eggs were cleaned and stored at 18-21oC for 6 days prior to setting in the incubator. The eggs were incubated in a forced-draft electric incubator and the hatching performances were recorded. Ninety Pekin and ninety Muscovy day-old ducklings were randomly selected from t...

An experiment was conducted to determine whether spraying hatching eggs with electrolyzed oxidizing (EO) water would decrease eggshell microbial load and hence improve hatchability, chick quality, and broiler growth performance. Eggs were collected from a broiler breeder flock; half the eggs were sprayed with EO water and the other half were left untreated. Enterobacteriaceae and total aerobic ...

Fifty white leghorn chicken (Gallus domesticus) eggs per group were injected with 0.1, 1.0, 10.0, or 20.0 microg perfluorooctane sulfonate (PFOS)/g egg before incubation to investigate the effects of PFOS on the developing embryo. Hatchlings were weighed, examined for gross developmental abnormalities, and transferred to a battery brooder, where they were raised for 7 d. Chicks were then weighe...

A 12-wks laying trial was conducted to study the effect of dietary chromiummethionine chelate supplementation on laying Japanese quail (Coturnix coturnix japonica) performance, egg quality, fertility %, hatchability % and some plasma constituents during summer months. A total of 225 laying Japanese quail (150 ♀+ 75 ♂) of 8 wks old were randomly assigned in 5 equal groups of 3 equal replicates e...

zataria multiflora essential oil, hydrogen peroxide(h2o2) and malachite green (mg) were used to assess their effects on rainbow trout egg hatchability and survival of larvae up to 1-1.2 g body weight using spring water at 12.5 °c, dissovled oxygen 8-9 mg/l, carbon dioxide 7±2 mg/l, ammunia

 Effect of nanosilver particles was studied on the hatchability of rainbow trout (Oncorhynchus mykiss) egg and survival of the produced larvae at about 12ºC. In the first experiment the water-based nanosilver particles was used at concentrations of 0.5, 1, 2 and 4 mgL-1 for 30 minutes per day starting 24 hour post egg incubation until the hatching time. The mean percentage of hatchability reach...

BACKGROUND Snail intermediate host control is a widely canvassed strategy for schistosomiasis control in endemic countries. While there have been increasing studies on the search for potent molluscicides in the past years, the use of nanoparticulate agents as molluscicides is yet to gain wide attention. The aim of this study was to assess the molluscicidal potential of curcumin-nisin poly lacti...

Exposing eggs multiple times to ultraviolet light (UV) and 3% hydrogen peroxide (H2O2) results in a greater reduction of eggshell bacteria compared to eggs treated only once with this combination. However, it is unknown if this repetitive treatment will have any effect on hatchability. Therefore, the objective of this experiment was to determine if hatchability would be affected by reducing egg...

This study aimed to investigate the effects of pre-incubation in ovo injection with different levels L- carnitine (L-Car) on hatchability traits Bronze Turkey eggs, blood plasma constituents and subsequent growth performance hatched chicks. A total 300 hatching eggs were chosen (averaged 80.0 g) randomly divided into four main groups each three replicates (25 each). The 1st group was used as a ...
