Inheritance of Egg Quality Traits in the Japanese Quail

International Journal of Poultry Science, 2013
A tot al of 471 eggs were collected from 205 female Japanese quails at 20 weeks of age in 3 consecutive days. The mixed model least-squares and maximum likelihood computer programme of Harvey (1990) was applied to estimate heritability, genetic and phenotypic correlations of egg quality traits.

Egg quality characteristics of South African Potchefstroom Koekoek and commercial Lohmann brown layer chickens: A comparative study.

PLoS ONE
Egg quality is an important feature in egg production and is affected by many factors, including the genetic makeup of the bird. However, the influence of the chicken genotype on egg quality traits is limited and inconclusive. Therefore, this study aimed

Phenotypic Correlations Between Egg Quality Traits Amid the Laying Phase of Broiler Breeder Hens

Contemporary Agriculture, 2022
In order to determine phenotypic correlations between the quality traits of eggs from 41-week-old broiler breeder hens (Cobb 500), a total of 105 eggs suitable for incubation were analyzed using descriptive statistics and Pearson’s correlation ...

Effect of Sulfanomides Residues on Egg Quality Traits

International Journal of Poultry Science, 2013
This study was conducted to detect the effects of Sulfanomide drug on table egg quality and to determine the withdrawal time after which eggs are save for human consumption. Sulfanomide (Coccidiofan) was administrated to 36 layer hens, at a dose of 1g/liter in the drinking water for three 3 consecutive days.

How phagocytic cells kill bacteria: Lessons from a professional killer

FEBS Open Bio, EarlyView.
How phagocytic cells ingest and kill bacteria has been studied for more than a century, but many questions remain unanswered. The study of the amoeba Dictyostelium discoideum brings new answers, and new questions. Professional phagocytic cells such as neutrophils and macrophages, as well as free‐living soil amoebae like Dictyostelium discoideum, employ

Seasonal variations in egg quality traits in Belgrade supermarkets

Biotechnology in Animal Husbandry
The aim of this study was to determine the quality of eggs available in Belgrade supermarkets during different seasons (winter, spring, summer), for various housing systems (cage, floor, and free-range), and to assess the representation of eggs from cage and non-cage systems in the year when Serbian egg producers have been granted an extended ...

Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Androgen Receptor‐Induced Lactoferrin Accelerates Prostate Tumorigenesis Through Modulating Ferroptosis

Advanced Science, EarlyView.
This study demonstrates that transcription factor androgen receptor (AR) directly binds the LF promoter, driving lactoferrin overexpression to promote ferritin (FTH1/FTL) upregulation and inhibit p53‐ALOX12‐mediated ferroptosis in prostate cancer. Lactoferrin could be a new potential therapeutic target in prostate cancer.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

Advanced Science, EarlyView.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Effect of Cage Density on Performance and Egg Quality Traits of Layers

Journal of Applied Animal Research, 2007
Abstract Sahin, S., Macit, M., Esenbuga, N. and Karaca, H. 2007. Effect of cage density on performance and egg quality traits of layers. J. Appl. Anim. Res., 31: 37–39. This experiment was carried out to assess the effect of cage density levels of 4, 5 and 6 birds per cage, at 540 (low-density=L), 432 (normal-density=N) and 360 (high-density-H) cm,2 ...
