Th is study was designed to investigate whether inclusions of coenzyme Q10, alpha lipoic acid and their combination into diets of hens improve egg quality characteristics. Forty-eight, 33 weeks old Lohmann Brown hens were assigned randomly to four groups of 12 hens each and fed either a basal diet or basal diet supplemented with 2 g/ kg coenzyme Q10, 0.4 g/kg alpha lipoic acid and 2 g/kg coenzy...

Successive generations of multivoltine species experience selection specific to the spatiotemporal environments encountered that may lead to adaptive divergence in reproductive traits among generations. To compare reproductive effort within and between generations, appropriate volumetric models, selected on the basis of the analysis of egg shape, are required to estimate the sizes (volumes) of ...

introduction breeding quail and quail egg industrial production because of the high nutritional value of these products has been developing these years. considering the high demand and economical production, further development in the future is predicted. in order to design and effective utilization of the equipment for transportation, separation, packaging and storage, the physical and mechani...

background: the foramen magnum (fm) is an important landmark of the skull base and a transition zone between spine and skull as well as its close relationship to the brain and the spinal cord. so the fm has gained considerable interest due to its comparative anatomy, ontogeny, clinical, and animal breeding viewpoints. objectives: the aim of this study was to determine morphology and morphometry...

The aim of the study was to analyze the pattern of oviposition time in laying sequences in broiler breeder hens and to determine a relationship between egg position in the sequence and egg quality. The sequences were described using mean oviposition time (hour) within a sequence, mean lag of oviposition time between successive ovipositions, and mean and cumulative lag of oviposition for a seque...

A total number of 225 Fayoumi hens 34 weeks old , were used in this experiment to study the effect of supplementing layer diet with 0.2% casein (c) with or without 0.015% iodine as 0.02% potassium iodide (KI) in drinking water on the performance and egg quality. The experiment continued for 90 days. Birds were randomly divided into three groups , each group contained 3 replicates of 25 each . B...

A study was conducted to determine the effect of live weight of partridges on egg production and egg quality characteristics. A total of 144 Rock Partridges were divided into control, heavy, middle, and light BW groups at 32 wk of age. Live weights averaged 512.78 g for the control group, 576.18 g for the heavy group, 523.49 g for the middle group, and 473.83 g for the light group. Egg producti...

the aim of current study was to determine the effects of vitamin c on bone mineral density (in terms of osteoporosis), eggshell quality and investigation of correlation between these factors in laying hens reared under normal condition. one hundred and ninety two 24 - weeks - old laying hens diet was supplemented with 4 levels of vitamin c (0, 250, 500 and 750 mg/kg diet). the experimental desi...

Eggs are an important and convenient source of protein for those living in rural regions. In addition, eggs from local hens popular traded a fair price. As result, the primary goal this study was to evaluate egg laying quality parameters Sakini (Gallus gallus domesticus) Nepal order better understand chicken’s reproductive fitness relationship between parameters. For this, total 120 different w...
