Palm kernel cake (PKC) is the main byproduct from the palm oil industry in several tropical countries that contains considerable amounts of oligosaccharide. We earlier demonstrated beneficial prebiotic effects of oligosaccharides extract of PKC (OligoPKC) in starter and finisher broiler birds. This study was envisaged to elucidate the effects of in ovo and/or oral administration of the OligoPKC...

BACKGROUND: In ovo injection of nutrients as an early feeding method in birds directly supplies the nu- trients to the developing embryo. OBJECTIVES: This study was designed to evaluate the effects of in ovo injection of nicotonic acid, panto- thenic acid and folic acid on the performance and immune system of broilers. METHODS: </st...

This experiment was conducted to investigate the effect of in ovo feeding (IOF) and dietary feeding of Silybum marianum (SM) extract on the immunity of chicken under heat stress conditions. A total of 360 fertile eggs from a commercial broiler breeder (Ross-308) farm was used for in ovo feeding of 0, 100 and 200 mg/L SM water extract at day 17.5 of incubation. After hatching, 240 chicks were tr...

BACKGROUND AND AIM Nanoparticles can bypass conventional physiological ways of nutrient distribution and transport across tissue and cell membranes, as well as protect compounds against destruction prior to reaching their targets. In ovo administration of nanoparticles, may be seen as a new method of nano-nutrition, providing embryos with an additional quantity of nutrients. The aim of the stud...

________________________________________________________________________________ Abstract Eggs from a meat-type breeder flock at 29 and 35 weeks of age were used in two trials to investigate the effects of in ovo feeding of carbohydrates (CHO) and high incubation temperature (37.5 vs. 38.5 °C (HIT)) during days 16 to 21 of incubation on hatchability traits, chick weight at hatch as an absolute ...

PURPOSE Following decapitation, the planarian Schmidtea mediterranea regenerates its head and eyes. The gene ovo is required for eye maintenance and regeneration in response to wounding. In this study, we investigated whether eye regeneration in S. mediterranea could occur absent a wound healing response. METHODS One hundred twenty S. mediterranea were treated with ovo RNA interference (RNAi)...

In ovo feeding is one way to increase poultry productivity by providing additional nutrition during the incubation period and can embryo growth. Many implementations of in-ovo techniques have been carried out on various types poultry, but a summary use has never reported, therefore this study was conducted. This review article aims determine in poultry. conducted based literature studies analyz...

The effects of in ovo feeding of carbohydrates on hatchability, BW, yolk sac weights (YSW), pectoral muscle weights (PMW), liver and pectoral muscle glycogen concentration, serum glucose level, and hepatic glucose-6-phosphatase activity of domestic pigeons, hatched from eggs laid by a 40-wk-old breeder flock, were investigated. At 14.5 of incubation, fertile eggs were injected with 200 μL of 1....
