Techniques for Identifying Fertile Hens’ Eggs

The Eagle’s EGGs: fertile or sterile?

We present a deep, high spatial resolution (0.35 arcsec FWHM), near-infrared (1–2.5 μm) imaging survey of the Eagle Nebula, M 16, made with the VLT, centred on the famous elephant trunks. We compare these data with the existing HST optical images to search for evidence of ongoing or recent star formation in the trunks, and in particular in the 73 small evaporating gaseous globules (EGGs) on the...

Prevalence of Salmonella Spp. On Exterior and Interior of Fertile Eggs from Vaccinated Breeding Hens of Different Breeds

Salmonellosis is one of the most common infections of poultry and other host species including human. It causes food borne diseases in humans when eggs may get contaminated by horizontal or vertical contamination [1]. Salmonella have been known to cause illnesses for more than 100 years and are Gram negative bacilli belonging to the Family Enterobacteriaceae. Like most Enterobacteriaceae they a...

ANNEX B Distribution of Salmonella Prevalence in Hens and Eggs ANNEX B - Distribution of Salmonella Prevalence in Hens and Eggs

The presence of Arcobacter species in breeding hens and eggs from these hens.

The presence of Arcobacter spp. in 2 breeding hen flocks was determined by examination of the intestinal tract, oviduct magnum mucosa, and ovarian follicles of slaughtered chicken. The bacteria were detected by PCR and cultural isolation in 34 out of 40 intestinal tracts from one flock (A) and 6 out of 30 from the other (B). The strains were Arcobacter butzleri, Arcobacter cryaerophilus, and Ar...

Vitamins A, E and fatty acid composition of the eggs of caged hens and pastured hens

In the US farmers often market pastured poultry eggs for a premium price, claiming animal and human health benefits. We examined how moving pastured hens to forage legumes or mixed grasses influenced hen (Gallus gallus L.) egg omega-3 fatty acids and concentrations of vitamins A and E. We also compared the eggs of the pastured hens to those of hens fed a commercial diet in cages. We used a cros...
