Designed-enriched products have been recently one of the most interesting areas research and innovation in animal production food industry. These are considered functional foods contain ingredients that beneficial physiological effects on human health. Designed or enriched eggs an important type poultry production. Demand for market has increasing recent years. Due to increased interest people ...

Remarkable progress has recently been made in molecular biology of double axis formation in Xenopus laevis. Leaving aside, for the time being, the problem of the gene expressions regulating Xenopus laevis development, here I show that pulse treatment could induce formation of a secondary axis in a fertilized Xenopus laevis egg. At 3 min after insemination, metal oxides were added to Xenopus fer...

The current study was carried out to evaluate the effect of phytogenic feed additive (PFA) on egg production performance in Hy-Line brown layer birds. A flock size 14190 birds selected commercial poultry farm which maintained with standard management practices at Spain. baseline data (T1) recorded for 20 days, thereafter, were fed PFA (500 g/ton) (T2) supplemented 11 days. parameters viz. numbe...

artificial neural networks (ann) have shown to be a powerful tool for system modeling in a wide range of applications. the focus of this study is on neural network applications to data analysis in egg production. an ann model with two hidden layers, trained with a back propagation algorithm, successfully learned the relationship between the input (age of hen) and output (egg production) variabl...

In a context of high productivity, eggs’ quality assessment is necessary for enhanced safety and quality assurance towards the consumers and feedback for producers. The quality assessment of eggs and egg products is performed using destructive and time-consuming methods, therefore the use of rapid tools becomes mandatory, especially in the case of a high production rate. Near Infrared (NIR) spe...

We tested the hypothesis that a negative fitness-density relationship exists in haematophagous ectoparasites. We studied the effect of flea density on the number of blood meals necessary for starting oviposition and egg production in Xenopsylla conformis and Xenopsylla ramesis when exploiting two rodent hosts, Meriones crassus and Gerbillus dasyurus. The number of blood meals taken by a flea pr...

Dormancy is a common adaptation in invertebrates to survive harsh conditions. Triggered by environmental cues, populations produce resting eggs that allow them to survive temporally unsuitable conditions. Daphnia magna is a crustacean that reproduces by cyclical parthenogenesis, alternating between the production of asexual offspring and the sexual reproduction of diapausing eggs (ephippia). Pr...

Aflatoxin B1(AFB1) and total Aflatoxins (AFT) contaminated feed effect on aflatoxins residue level in eggs, muscles (breast, leg), organs (liver, kidney, gizzard) and excreted aflatoxins in chicken litter of layer hens were monitored. Laying hens were on four levels of aflatoxins for 6 weeks and monitored weekly for the change in both AFB1 and AFT levels. Pronouncedly, the AFB1 and AFT were det...

In areas where schistosomiasis is endemic, a negative correlation is observed between atopy and helminth infection, associated with a low prevalence of asthma. We investigated whether Schistosoma mansoni infection or injection of parasite eggs can modulate airway allergic inflammation in mice, examining the mechanisms of such regulation. We infected BALB/c mice with 30 S. mansoni cercariae or i...
