The experiment studies the injection of a HEPES buffer into the stored eggs in three groups (14 days for the first group, 7 for the second, and 4 for the third). It also investigates the prolongation of the storage period of hatching eggs by injecting them with HEPES buffer in addition to its effect on the qualitative hatching characteristics and chicks specification. The groups of eggs were injected with HEPES buffer of (H50 mM, H75 mM) concentration and then stored for 14, 7 and 4 days. The eggs were brought in groups from the fields of broiler mothers, ROSS 308 breed, from the Modern Poultry Company in (Wasit, Azizia). The first group of 294 days old (42 weeks) was stored for 14 days. The second group of age 308 days (44 weeks) was stored for 7 days and the third, at the age of 311days, was stored for 4 days. The eggs were divided into 15 treatments of 30 eggs each. At the end of the storage period, the results of the experiment show that injecting HEPES buffer with a concentrati...

The hypothesis of modulating stressor factors such as raising chicks in batteries by synbiotic treatment were studied. Two major factors; types of raising (batteries and litter) by four synbiotic treatment were conducted in factorial experiment (2×4), 288 unsexed one day old chicks were distributed into 8 treatments (interactions between the major factors), with three replicates per treatment and 12 chicks per replicate (36 chicks/ treat.). Field experiment was carried at one of poultry houses (Animal Resources Dept./ College of Agriculture/ Al-Anbar university), the trial lasted 49 days from 4 th Dec., 2011 to 22 th Jan., 2012. The chicks were raised at litter and treated with encapsulated synbiotic mixture 1 (ES1), ES2, encapsulated feed (EF), no encapsulate, (NE) in 1 st , 2 nd , 3 rd and 4 th treatments respectively, and in 5 th , 6 th , 7 th and 8 th treatments the chicks were raised in batteries with ES1, ES2, EF and NE respectively. ES1 was contained 300 mg of prebiotic;100 mg of chicory (Cichorium intybus(, 100 mg of Jerusalem artichoke (Helianthus tuberosus( and 100 mg of Saccharomyces cerevisiae + 100 mg of probiotic (at least 10 8 CFU of Lactobacilli, Lactobacillus acidophilus, Bacillus subtilis and S. cerevisiae). ES2 contained 200 mg of prebiotic; 75 mg of chicory and 75 mg of Jersualem artichoke + 200 mg of probiotic. There were insignificant effect of two majors factors and its interactions on accumulative broiler performance of first four weeks of age (0-28 days), whereas, raised chicks in batteries caused significant decreases in accumulative weight gain, feed consumption and relative growth rate (RGR) at last three weeks of broiler age (29-49 days), synbiotic treatment significantly decreased the effect of batteries stress on accumulative feed consumption and RGR in chicks that raised in batteries and treated with synbiotic mixtures. The same trend was noticed in accumulative broiler performance in whole period (0-49 days) in batteries major factor through significantly decreasing final body weight, accumulative weight gain, feed consumption and RGR. Synbiotic treatments interact with batteries to reduce their effects on performance traits except final body weight. Type of raising and synbiotic mixtures were insignificantly affect carcass traits, but synbiotic mixtures significantly decrease effect of batteries factor in relative weight of breast and wings.
