The Effect of Natural Aromatase Blocker on the Growth Comb and Body Weight of Layer Chicken [PDF]

BIO Web of Conferences, 2022
The aim of this research is to evaluate the effect of Anadara granosa shell powder as a natural aromatase blocker (NAB) and zinc sulfate (ZnSO4) on the growth of the length comb, width comb, and body weight (BW) of layer chicken.

Genetic variation in eggshell crystal size and orientation is large and these traits are correlated with shell thickness and are associated with eggshell matrix protein markers [PDF]

, 2012
The size and orientation of calcium carbonate crystals influence the structure and strength of the eggshells of chickens. In this study, estimates of heritability were found to be high (0.6) for crystal size and moderate (0.3) for crystal orientation ...

Low Pathogenic Avian Influenza Exposure Risk Assessment in Australian Commercial Chicken Farms

Frontiers in Veterinary Science, 2018
This study investigated the pathways of exposure to low pathogenic avian influenza (LPAI) virus among Australian commercial chicken farms and estimated the likelihood of this exposure occurring using scenario trees and a stochastic modeling approach ...

The chicken embryo and its micro environment during egg storage and early incubation [PDF]

, 2008
When egg storage periods are prolonged (>7 days), hatchability and chick quality declines. The reason for this decline has been investigated, but is still not completely understood.

Route of infectious bronchitis virus vaccination determines the type and magnitude of immune responses in table egg laying hens

Veterinary Research, 2021
Chicken immune responses to infectious bronchitis virus (IBV) vaccination can depend on route of administration, vaccine strain and bird age. Typically for layer chickens, IBV vaccinations are administered by spray in the hatchery at day-old and boosted ...

Eimeria species occurrence varies between geographic regions and poultry production systems and may influence parasite genetic diversity [PDF]

, 2017
Coccidiosis is one of the biggest challenges faced by the global poultry industry. Recent studies have highlighted the ubiquitous distribution of all Eimeria species which can cause this disease in chickens, but intriguingly revealed a regional divide in

Immunopathogenesis of Ascaridia galli infection in layer chicken

Developmental & Comparative Immunology, 2011
Gastro-intestinal nematode infections in mammals are associated with local T lymphocyte infiltrations, Th2 cytokine induction, and alterations in epithelial cell secretion and absorption. This study demonstrates that Ascaridia (A.) galli infection in chicken also elicits local gut-associated immune reactions and changes in the intestinal electrogenic ...

Comparison of Growth Curve in Male Layer Chickens

Journal of Research in Veterinary Medicine, 2021
This study was aimed to obtain the growth curve of body weight in male layer chickens (Lohman MB 202) based on Logistic and Gompertz models. The frequently data of body weight from one day age to adult age were used for growth curve prediction. Total of one thousand birds from private sector poultry farm in Tasikmalaya Regency, Indonesia were used in ...

Carcass and meat quality of dual‐purpose chickens (Lohmann Dual, Belgian Malines, Schweizerhuhn) in comparison to broiler and layer chicken types

Poultry Science, 2018
Currently, there is an intensive ethical discussion about the practice of culling day‐old layer cockerels. One solution to avoid this practice could be using dual‐purpose types, where males are fattened for meat and females used for egg production.
