Introduction: Vitamin D3 is one of the important vitamins in calcium metabolism, which increases the active transport of calcium and phosphorus in the intestinal epithelium. However, the mechanism by which vitamin D3 increases the absorption of calcium and phosphorus is not fully understood. The active form of vitamin D3 or 1,25-hydroxycalciferol is transported to the nucleus of the intestinal cells. In the presence of 1, 25-hydroxycalciferol, a specific RNA is secreted from the cell nucleus, which is translated into a specific protein by the ribosomes, thereby increasing the uptake of calcium

In avian species, the central nervous system orchestrates feeding behavior through intricate interplay among diverse neurotransmitter pathways. Epidermal Growth Factor (EGF), a key peptide in cell growth and repair, has been implicated in appetite control in mammals, but its role in avian species remains unexplored. The present study was conducted to investigate the effect of central infusion of EGF on food consumption in neonatal broilers and to determine the possible involvement of dopaminergic and adrenergic systems. In a series of experiments, 5-day-old male broilers were subjected to intr

Artificial incubation is a potential solution to mitigate the impact of nest harvesting on wild populations. This study aimed to examine the morphological characteristics of swiftlet eggs from Buntok, Central Kalimantan, and their hatchability under controlled incubation.

ABSTRACT Dietary inclusion of lipid sources has been one of the methods adopted by nutritionists aiming at better energy balancing. However, alternative energy feedstuffs have been sought in an attempt to reduce production costs. In this regard, lipid sources that can replace conventional ones, such as beef tallow, cottonseed oil, and sunflower oil have been investigated. The objective of this study was to examine the effects of different lipid sources on the performance, egg quality, biometrics of digestive organs, and bone quality of white-egg commercial layers in the first production cycle.
