Silky Fowl (Gallus gallus domesticus) Dietary Supplementation with Dried Red Pepper (Capsicum annuum): Effects on Egg Quality, Blood Biochemical Parameters, and Egg Storage Stability
Egg yolk coloration influences consumer perceptions of table eggs. Red pepper (Capsicum annuum) is a known dietary source of carotenoids, which enhances yolk pigmentation, but its effects in silky fowl (SF) remain unexplored. We examined how dried red pepper flakes influence blood biochemical…

A Model to Describe the Genetic Potential for Nitrogen Deposition and Estimate Amino Acid Intake in Poultry
The maximum protein or nitrogen deposition is commonly used as the basis for modeling the amino acid intake in growing birds. In previous studies, the exponential functions of the nitrogen balance data were used to estimate the theoretical maximum for nitrogen deposition (NDmaxT) as a reference…

Determination of the Requirements of Standardized Ileal Digestible Methionine Plus Cysteine and Lysine in Male Chicks of a Layer Breed (LSL Classic) During the Starter Period (1–21 d)
In most countries, male siblings of laying hybrids are culled immediately after hatching because their rearing is economically unfeasible due to low growth performance, poor feed efficiency, and a body composition unacceptable to consumers. In Germany, however, culling male day-old chicks has been…

Expression of the 60 and 70 kDa Family of Heat Shock Proteins in Trachea Epithelium Cells of Poults Experiencing Bordetellosis
Heat shock protein (HSP) gene families are known to be expressed preferentially over normal cellular proteins when poultry cells are exposed to environmental stressors. Bordetella avium infection leads to bordetellosis, which is characterized by severe inflammation of the tracheal epithelium…

Morphometrics and Density of Japanese Quail Eggs vs. Their Fertility and Hatchability: Preliminary Findings from a Pilot Trial
Pre-incubation sorting for infertile and non-viable eggs could save significant resources in quail farming. Previous research has revealed often contradictory correlations between egg morphometric parameters used to assess incubation success. The current pilot study aimed to identify these…

Effects of Bedding Materials on Growth Performance, Footpad Dermatitis, Blood Parameters, and Economic Outcomes in Broiler Chickens
A 42-day trial compared rice hulls and rubberwood shavings as broiler litter applied at an equal rate (7.5 kg/m2) in a house equipped with an evaporative cooling system. A total of 552-day-old male Ross 308 broiler chicks were randomly assigned to two treatments, with 12 replicate pens per…

Microbiological Investigations of Bacteria Infecting Yolks of Broiler and Broiler Breeder Embryos and Hatchlings
Enterococcus cecorum has been identified as causing early sepsis in commercial broilers. We hypothesized that vertical transmission may contribute to the spread of the pathogen. Sampling of 360 commercial broiler eggs from a previously infected flock detected Enterococcus gallinarum and…
