ABSTRACT The aim of this study is to evaluate the influence including levels calcareous seaweed flour in replacement for calcite limestone on diet under egg conservation at different storage periods. 140 Japanese quails were used a completely randomized experiment consisting 4x4 factorial design. design was four inclusions (0%, 10%, 20%, and 30%) periods (zero, seven, 14, 21 days) with ten repl...

The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – ...

the experiment was designed to study the changes in production performance and egg quality of old laying hens after injection of different doses of growth hormone (gh) and testosterone (ts). a total of 160 old laying hens (hyline w-36) at 73 wks of age were randomly assigned to four treatments with four replicates and 10 birds in each replicate in a completely randomized design. treatment group...
