The aim of this study was to assess the performance and meat quality of meat-type guinea fowl fed commercial diets under two different feeding programs similar to those for turkeys and broilers. Findings of the study suggest that these diets can be used in meat-type guinea fowl rearing without affecting the productive traits and meat quality. However, due to the lower price of chicken feed (due to lower protein content), its use seems to be more justified from an economic point of view.

The results of this research indicate that eggs from organic farming have a richer chemical composition in terms of the content of nutrients such as calcium, magnesium and zinc compared with eggs obtained from caged hens. Therefore, consumers purchasing eggs should consider the system in which the hens were reared, as eggs can be a valuable source of these elements in the diet.

The aim of this study was to evaluate the time to sexual maturity and the quality of the initial eggs of Japanese quail affected by in ovo injection of plants extracts: ginger, garlic, oregano and cinnamon. The in ovo use of medicinal herbs may considerably modify both the time of sexual maturity and the quality of the initial eggs of Japanese quail.

Glycerol, a by-product of biodiesel production, is non-toxic to humans and environment. With the increase in demand for fuels obtained from biomass, the amount of glycerine waste increases. There are many ways to dispose it (pharmaceutical, cosmetics and chemical industry), but its utilization is still insufficient. Due to the fact that glycerine is a safe, cheap and easy to apply substance, the possibility of using it on a large scale in the aspect of chicken eggs storage seems to be possible.

This paper shows the impact of the rearing system used for laying hens on their productivity and egg quality. Newly created laying hen hybrids dedicated to organic or pro-ecological farming were used. The results showed different reactions of two types of hens to extensive and intensive rearing systems. A significant positive impact of the extensive rearing system (access to open runs, natural length of daylight, farming fodders) on birds and their productivity was found.
