________________________________________________________________________________ Abstract In this study dietary boron at different doses (0, 25, 50, 100 and 200 mg/kg feed) was supplemented to layers from 4 to 64 weeks of age. There was no significant difference between treatments with respect of mortality, egg production, egg weight, egg mass and cracked eggs. Significant increases were observ...

This study evidence for tension transmission by microtubules and desmosomes in the follicular epithelium during anisometric growth of certain insect eggs. Most insect oocytes, and the follicles which surround them, grow anisometrically as they assume shapes which approximate to those of long prolate spheroids. Surface growth is most rapid in directions which parallel the polar axis of an oocyte...

Meat and bone meal (MBM) and oyster shell meal (OSM) were supplemented to a basal diet (LMS), either alone or in combination, in order to assess the dietary influences of those complementary Ca sources on performance and egg quality of laying hens. Four hundred and thirty-two Brown-Nick hens, at the beginning of their second production period, were divided into four treatment groups with six re...

We propose an Economic Stability Index (ESI) incorporating house prices and stock prices as components of the measure of the inflation rate in order to allow the European Central Bank (ECB) to achieve both price and macroeconomic stability. We use an optimisation approach to estimate target weights for different sectoral prices in the broader price index, which depend on sectoral parameters oth...

The evolution of egg shape across birds has been associated with breeding ecology, body constraints and nest microclimate, among other factors. We model the effects migratory status, climate, clutch size volume on variation over distribution fork-tailed flycatchers Tyrannus savana. Although status climatic variables appear to be influencing intraspecific shape, these are not significant when ac...

In this study, it was aimed to determine the internal and external quality traits of the Guinea fowl eggs as well as the phenotypic correlation among the these traits. Totally 100 Guinea fowl eggs were collected in three sequential days were used for this study. The birds were housed at Poultry Research Unit of the Department of Animal Science, Faculty of Agriculture, University of Akdeniz. Val...
