the experiment was carried out in poultry experimental station belonging to nrc, cairo, egypt. a total of 120 fayoumi layers, 45 weeks old, were randomly divided into four equal groups. each group included three replicates (10 hens in each). the first group was fed the control diet containing 3.3% gram ca, whereas, the other three received diets containing 2.8, 2.6 and 2.4% gram ca, respectivel...

This study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (PSP) on performance and blood parameters in laying hens. A total of 96 layers hens (Hy-line W-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of PSP, with 4 replicates containing 6 layers in each. Results showed no significant effec...

This trial was conducted to evaluate the effects of high-dose daidzein supplements on laying performance, egg quality and antioxidation in laying hens during the late laying period. Seven hundred sixty eight 55-wk-old Hyline Brown were randomly assigned to four groups with 8 replicates of 24 birds each (192 laying hens per group) and fed diets supplemented with 0 (control), 10mg/kg, 50mg/kg and...

the objective of this study was to evaluate the effect of frying temperature, time and different batter formulations on the rheological properties and mass transfer during deep fat frying of kurdish cheese nuggets. the effects of white egg (0, 5, 10%) addition to the batter formulation of cheese nuggets and frying at 150, 170 and 190◦c for 0, 1, 2, 3 and 4 min have been investigated. the result...

Effects of soil matrix potential on longevity of egg masses of Meloidogyne incognita were determined during simulated winter conditions. Egg masses were recovered from isolated root fragments incubated in field soil at matrix potentials of -0.1, -0.3, -1.0, and -4.0 bars throughout winter survival periods of 10 weeks for tomato roots and 12 weeks for cotton roots. Egg masses were more superfici...

this study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (psp) on performance and blood parameters in laying hens. a total of 96 layers hens (hy-line w-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of psp, with 4 replicates containing 6 layers in each. results showed no significant effec...

In birds, egg size aff ects chick growth and survival and it is an important component of reproductive success. Th e shiny cowbird Molothrus bonariensis is an extreme generalist brood parasite that uses hosts with a wide range of body masses. Survival of cowbird chicks decreases with host body mass, as competition for food with nestmates is more intense in large than in small hosts. We studied ...

Understanding reproductive performance in ecologically impoverished vs. more sustained anthropogenic habitats is critical to assess population health status and to develop land use and conservation management strategies. We compared resourcebased maternal effects, reproductive performance, and offspring quality in a model migratory passerine bird, the European starling (Sturnus vulgaris). We as...

the present study is based on the investigation of a soil hyphomyces, paecilomyces lilacinus, an opportunistic bio-control agent, in controlling root-knot nematode meloidogyne javanica on tomato in greenhouse conditions. p. lilacinus, effectively promoted the growth of plants inoculated with m. javanica by suppressing its pathogenesis as root galling by the nematode and egg mass production was ...

The objective of this experiment was to compare the effects of 2 sources of phytase on performance of commercial Leghorns fed corn-soy diets. Seven diets were fed to Hy-line W-36 hens (n = 840; 8 replicates of 15 hens per treatment) from 21 to 33 wk of age. The treatments consisted of a control diet containing 0.38% nonphytate P (NPP) and a 2 x 3 factorial arrangement of 2 dietary NPP concentra...
