Abstract

The purpose of the current study was to detect the effects of different levels of rosemary volatile oil (VO) supplemented to laying quail diets on performance, egg quality parameters, and egg yolk oxidative stability. In this study, a total of 105 laying quails (Coturnix coturnix Pharaoh) at the age of 6 weeks were used and 3 main groups were formed, each containing 35 quails. Also, each main group was separated into 5 replicates containing an equal number of quails. Quails were fed a control diet without rosemary VO or diets which were containing at different levels (200 or 400 mg/kg) of rosemary VO supplemented to the control diet. At the end of the study, which was continued for a total of 56 days, no significant difference was found in the feed intake, feed efficiency and egg weights among the control and experimental groups. The supplementation of rosemary VO at the levels of 200 and 400 mg/kg to the diets caused an increase in quails' egg production (P<0.01). However, there was no effect on the exterior and interior egg quality parameters. A significant decrease in malondialdehyde (MDA) levels in egg yolk were observed with both levels of rosemary VO at storage (+4 0 C) for 7 (P<0.001) and 28 (P<0.01) days. Considering these data, it was concluded that rosemary VO can be supplemented to laying quail diets as a natural antioxidant without negatively affecting performance and egg quality parameters.

The physical characteristics of quail egg fed lower grade tobacco as a feed additive in the tropical environment

“…However, the egg weight of quail which fed rations with lower grade tobacco tent to increase as the additive level increased and it was equivalent to previous research of ranged stocking densities combined with ascorbic acid usage in a hot tropical environment that ranged 9.2-9.5 g [9]. Contrary, it was lower than the weight of quail eggs spread out in several markets in Jember Regency which is 11.9-12.20 g [21] as well as the study of supplementing rosemary volatile oil in laying quail diets resulted egg weight ranged 11-11.6 g [13]. The different weight of quail eggs might be caused by the type of quail and diets, environmental conditions, and the treatment applications.…”

“…Several studies have been carried out to reduce the impact of quail heat stress in tropical environments, either by regulating population density [5] or through feed additive [6] and supplementation [7,8] approaches. Generally, heat-stress of laying poultry is reduced by adding antioxidants chemically [9] or herbal [10] in the form of vitamins [11], selenium [12] or others [13]. One of the potential feed additives due to potential bioactive compounds, antioxidant and antimicrobial properties in Jember Regency is tobacco waste.…”

Potential implications of natural antioxidants from plant to improve nutritional quality, oxidative stability and lipid degradation of egg yolk: A review

“…Rosemary is an aromatic plant specific to the Mediterranean climate (Deniz et al, 2022). Belong to the Labiatae family, rosemary is known as a herb with the highest antioxidant activity (Estevez et al, 2007).…”

The Effect of In Ovo Administration of Rosemary Essential Oil on Hatchability, Relative Hatching Weight, and Embryo Mortality Rate in Japanese Quail (Coturnix coturnix japonica)

“…Specifically, Rosmarinus officinalis EO appears to be one of the most interesting and efficient supplements in poultry diets; it has been proved to provide antioxidative (effective against oxidative stress), antimicrobial, and growth stimulator effects in different avian species [ 18 , 19 ]. In the last few years, in ovo technology has not been restricted to the improvement of growth performance or the prevention of avian diseases; instead, this technique has been widely used to fight against antibiotic resistance by administering upstream plant extracts (substitute molecules) in relation to their antioxidant, antimicrobial, and growth enhancer properties on the embryonic development of avian species [ 11 , 20 ].…”
