Reliance on seasonal wild harvests of the edible long-horned grasshopper Ruspolia differens (Serville) (Orthoptera: Tettigoniidae) needs to be broken through developing efficient mass rearing protocols. This study aimed at boosting productivity laboratory colonies R. understanding ways minimising cannibalism, selecting suitable oviposition substrates and enhancing egg development hatchability. ...

Dolenec, Z.: Breeding characteristics of the barn swallow (Hirundo rustica) in NW Croatia. Nat. Croat., Vol. 11, No. 4., 439–445, 2002, Zagreb. The research was carried out in the village of Mokrice (46°00'N, 15°55'E) in NW Croatia during 1998–1999. Egg length averaged 19.16 mm, egg breadth 13.72 mm, egg volume 1840.8 mm3, egg shape index 1.40 and egg weight 1.81 g (during both years). The nest...

objective: both the length of extra-alveolar time and type of storage media are significant factors that can affect the long-term prognosis of replanted teeth. this study aims to compare propolis 50%, propolis 10%, hank’s balanced salt solution (hbss), milk and egg white on periodontal ligament (pdl) cell survival for different time points. materials and methods: in this in vitro experimental s...

Whole-tissue rotations have recently been recognized as a widespread morphogenetic process important for tissue elongation [1-4]. In Drosophila ovaries, elongation of the egg chamber involves a global rotation of the follicle epithelium along the anterior-posterior axis [5]. Individual egg chambers rotate either in a clockwise or counterclockwise direction; however, how the symmetry of egg cham...

in this study, the effects of dietary egg lecithin on digestive enzymes and body biochemical composition of juveniles mesopotamichthys sharpeyi was evaluated. four experimental diets including control diet (with 0% egg lecithin) and three diets containing 2%, 4% and 6% egg lecithin were used. at the end of the experiment, digestive enzymes activity (lipase, amylase and alkaline phosphatase) and...

An experiment was conducted to determine whether egg quality during the late stage of egg production can be improved by using diets that are effective in reducing egg size. The experiment was conducted in completely randomized design with six treatment groups and four replicates each with ten hens from 94 to 106 wk of age. Three 28-d periods used for different dietary factors including: 1) Cont...

In this study, the effect of basil seed gum (BSG) on the stability and rheological properties of egg white albumin (EWA) emulsions was investigated. A constant amount of EWA (0.5% w/v) and different concentrations of BSG (0-0.3% w/v) were used for the manufacture and stabilization of oil-in-water emulsions (30% w/w). The results showed that by increasing BSG concentration, the storage (21 days)...

this experiment was conducted to evaluate and compare antibiotic, organic acid, probiotic and prebiotic effects on performance, egg quality and blood metabolites in commercial laying hens. the experiment was a completely randomized design with 160 laying hens strain hy line (w-36) from 32 to 42 weeks of age with 5 treatments and 4 replicates of 8 hens each. the experimental treatments consisted...

INTRODUCTION We present a case of quail's egg allergy without allergy to chicken's egg. CASE Girl of 10.5 years old who presents anaphylactic reaction after she ate an uncooked quail's egg. She had eaten boiled quail's egg before. She eats chicken's eggs without clinical symptoms. METHODS We made a prick to chicken's egg and prick-by-prick to uncooked quail's and raw chicken's egg. We deter...

The C. elegans egl-36 gene encodes a Shaw-type potassium channel that regulates egg-laying behavior. Gain of function [egl-36(gf)] and dominant negative [egl-36(dn)] mutations in egl-36 cause reciprocal defects in egg laying. An egl-36::gfp reporter is expressed in the egg-laying muscles and in a few other tissues. Expression of an egl-36(gf) cDNA in the egg-laying muscles causes behavioral def...
