The present study investigated the effect of supplementing a diet containing 5 % soybean oil, which provided 30 g/kg of polyunsaturated fatty acids (PUFAs), with two levels of vitamin E (30 or 60 mg/kg, as-is basis) in combination with two levels of selenium (0.15 or 0.30 mg/kg, as-is basis) on hen performance, the fatty acid profile and antioxidant status of the yolk. A 12-week study was perfo...

A study was conducted to assess the physical characteristics, chemical composition and fatty acid profile of ostrich eggs. Fifteen eggs were collected randomly and used for the conduct of study. Studies revealed the average size to be 1435.1 ± 20.10 g, length 151.5 ± 0.83 mm, width 113.6 ± 0.34 mm, shell thickness 2.56 ± 1.12 mm and shape index 74.2 ± 0.82. Three principal components amounted t...

Marigold flower extract (MFE), a natural source of xanthophylls, was added to the diets of hens at different concentrations (0, 150, 250, and 350 mg/kg of diet) to determine the effects of MFE on hen performance, physical characteristics of egg quality, and carotenoid content of the egg yolk of hens housed in enriched cages. Additionally, the highest dose of MFE (350 mg/kg) was tested under com...

Abstract: ‘Sarabba’ is a popular traditional drink that mostly consumed in South Sulawesi Province, Indonesia. has been known for its health benefits because ingredients contain some spices, but this poorly studied. This study aimed to characterise the physicochemical properties, sensory perception, and volatile compounds of ‘Sarabba’. The importance was provide valuable insight small-scale man...

Astronotus ocellatus, popularly known as Oscar, is a cichlid fish from the Amazon basin (Brazil) with a great potential for fish farming. The aim of this research is to describe the morphology of eggs and larvae of A. ocellatus under stereomicroscopy and scanning electron microscopy. Eggs from natural spawnings were taken to hatcheries, collected at previously established time periods and then ...

The present study was conducted to determine egg production traits and egg quality characteristics in black and brown lines of Japanese quail. A total of 500 quails comprising 400 females and 100 males obtained from two breeding centers were raised according to the standard procedure for Japanese quail. They were grouped in according to their plumage colours. Age at first egg-laying has been re...

For reasons of aspired naturalness and cost reduction, vitamin additions should be kept low in organic livestock systems. To define safe lower threshold levels riboflavin supplementation poultry feeding, 135 hybrid layers were allocated to three dietary treatments supplemented with either 4.5 (R4.5), 3.0 (R3.0) or 1.5 mg (R1.5) GMO-free added per kg feed. This resulted total measured concentrat...

The quality of eggs and the hatching traits of two slow-growing lines – La Belle (LB) and Bresse Gauloise (BB) reared under conventional or alternative system with pasture access were compared. The birds of both lines in the study were at the age of 27-37 weeks. Two-way ANOVA was used to assess the effect of the rearing system as well as the line on the quality characteristics of the eggs and h...
