Histological Study of Exocrine Portion of Pancreas in Guinea fowl (Numida meleagris)

Wasit Journal for Pure Sciences, 2023
 The histological structure of the exocrine pancreas was examined in the current study for fifteen healthy adult female Laying hens. The study showed the pancreas was serous tubuloacinar gland, which has both an exocrine and an endocrine component, the ...

Age-Related Involutory Changes in Bursa of Fabricius of Anas crecca: Histomorphometric and Ultrastructural Investigation. [PDF]

Vet Med Sci
This scientific diagram illustrates age‐related changes in the Bursa of Fabricius (BF) of green‐winged teal (Anas crecca) ducks at two developmental stages. In the 8th week, the BF shows maximum maturation with peak morphometric measurements (body weight, bursal dimensions), the thickness of cortex and medulla layers and well‐developed ultrastructure ...

Photoperiodic-dependent morpho-biometric changes in the excurrent duct system of sexually-matured helmeted guinea fowl (Numida meleagris)

Sahel Journal of Veterinary Sciences, 2022
Photoperiod is considered to be one of the most effective environmental factor in controlling the reproductive cycle and gonadal maturation in some mammalian species, but very limited information are available on its effects on  reproductive biology of ...

Interspecific germline transmission of cultured primordial germ cells. [PDF]

PLoS ONE, 2012
In birds, the primordial germ cell (PGC) lineage separates from the soma within 24 h following fertilization. Here we show that the endogenous population of about 200 PGCs from a single chicken embryo can be expanded one million fold in culture.

Histological and Histochemical Study of the Esophagus Before and After Crop in the Guinea Fowl (Numida meleagris)

Egyptian Journal of Veterinary Sciences
. Abstract SOPHAGUS is an important organ of the digestive system and having different layers of tissue in every species of animal plays an important role in digestion. The length and diameter of the esophagus are also different in animals and without on

Observations on the embryonic development of domestic meat-type guinea fowl (Numida meleagris)

Italian Journal of Animal Science, 2021
Guinea fowl breeding for meat production is widespread across Europe and the USA. For hatcheries to achieve their output potentials, they need in-depth knowledge about incubation techniques and guinea fowl embryonic development. The aim of this study was

A Dynamics and Stability Framework for Avian Jumping Take-off

, 2018
Jumping take-off in birds is an explosive behaviour with the goal of providing a rapid transition from ground to airborne locomotion. An effective jump is predicated on the need to maintain dynamic stability through the acceleration phase.

Rheological and Flow Behaviour of Yolk, Albumen and Liquid Whole Egg from Eggs of Six Different Poultry Species

Foods, 2021
Liquid egg products are one of the basic raw materials for the food industry. Knowledge of their rheological and flow behaviour in real technical elements is absolutely necessary for the selection of suitable technological equipment for their processing.

Effect of Body Configuration on Perturbation Resistance Across Arboreal Lizard Species

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 2, Page 127-136, March 2026.
ABSTRACT Animals that inhabit high‐risk habitats often exhibit morphological and behavioral adaptations to contend with environmental challenges. In arboreal (tree‐based) habitats, such adaptations can include corrective behaviors, such as modification of body‐limb angles, to avoid dislodgement by perturbations.

Adsorption of Toxic Metals from Landfill Leachate onto Guinea Fowl Eggshells in the Era of Green Chemistry

BioResources, 2023
One of the best and most affordable ways to remove harmful metals from water is by adsorption. This study investigated the efficiency of guinea fowl (Numida meleagris) eggshells as a low-cost adsorbent for cadmium (Cd) and nickel (Ni) removal from ...
