The effects of nanosilver on egg quality traits in laying Japanese quail

Abstract

Silver nanoparticles could prove to be a valuable alternative raw material for antibiotics and disinfectants as it is relatively free of adverse effects. Nanosilver is now been put to practical use in commonly used items, such as, clothes, electric home appliances, and electronic industry, but has not been widely applied in the medical or pharmacological fields. This study was designed to investigate the effects of nanosilver on egg quality traits in laying Japanese quail in completely randomized design with four treatments and six repetitions at 0, 4, 8 and 12 ppm of silver nanoparticle levels. Eggs collected daily and egg parameters, including egg weight, length, width; yolk weight and eggshell thickness were examined. The effect of the different silver nanoparticle levels was determined using the General Linear Model of SAS procedure, whilst differences between the groups were determined using least significant difference test. Results indicated that silver nanoparticles at all levels caused significantly reduce of yolk weight and hen-day egg production for each week than the control treatment (P \ 0.05), whilst silver nanoparticle had no significant effect on egg weight, egg length and width and eggshell thickness.

Silver (Ag) in tissues and eggshells, biochemical parameters and oxidative stress in chickens

“…For three days, there was a rapid decline Previous studies have shown that silver nanoparticles are absorbed and metabolized by soft tissues where they display toxic activity and produce macro-and/or microscopic changes [19,20].…”

“…In the work of Sawosz et al [6] and Fondevila et al [7] the application of silver nanoparticles is investigated as a likely alternative to feed additives for stimulating bird growth. A number of authors have emphasized that nanosilver is a disinfecting agent that is relatively safe for health [2,7,19]. However, its potential use in poultry production needs more thorough studies on its possible toxic effects.…”

The Measurement of Cadmium, Zinc and Silver in Chicken Meat in Isfahan Province, Iran

“…These compounds are now used less in water and chicken feeds. However, according to two recent studies, the application of these compounds even on the mucosa can be absorbed and affect the chickens [30,31]. Finally, the current accumulation of silver ions in meat and other edible tissues of chickens supplied in Isfahan, is very minimal.…”

Effects of Light Intensity and Photoperiod on growth and reproductive performance of Coturnix japonica: A review

“…Higher body weight gain rates in birds may be to less energy expenditure and better feed intake by the birds. The interaction among energy intake and expenditure significantly affects the overall performance of birds particularly body weight gain (Farzinpour et al, 2013). Overall body weight gain increases by modulating the light duration and consequently decreasing dark period for birds to improve intake It is evident that consequences of food activity depends upon the photoperiod.…”
