A total of 1800 broiler breeder , Ross 308 at 47 wks old , hatching eggs .Were used in the present study . Eggs were randomly distributed into 12 experimental treatments ,150 eggs pretreatment groups . The treatment groups were as follows :
T1 treatment without pre-incubation + 4 days eggs storage period
T2 treatment without pre-incubation + 8 days eggs storage period
T3 treatment without pre-incubation + 12 days eggs storage period
T4 treatment 4 hours pre-incubation + 4 days eggs storage period
T5 treatment 4 hours pre-incubation + 8 days eggs storage period
T6 treatment 4 hours pre-incubation + 12 days eggs storage period
T7 treatment 8 hours pre-incubation + 4 days eggs storage period
T8 treatment 8 hours pre-incubation + 8 days eggs storage period
T9 treatment 8 hours pre-incubation + 12 days eggs storage period
T10 treatment 12 hours pre-incubation + 4 days eggs storage period.
T11 treatment 12 hours pre-incubation +8 days eggs storage period
T12 treatment 12 hours pre-incubation + 12 days eggs storage period.
Experimental parameters measured included : Fertility , hatchability percentage from the total incubated eggs and from fertile eggs , hatching chicks length , weekly embryonic mortality ,piped eggs and quality evaluation of navel for hatching chicks .
The results of this study showed a significant increase (P <0.05) in the rate of early embryonic mortality of the treatment which was pre- incubated for 8 hours and stored for 12 days compared to the treatment that was unpre-incubated and stored for 4 days, medium embryonic mortality increased to a treatment which was pre-incubated for 8 hours and stored for 12 days compared to the treatment that was pre-incubated for 8 hours and was stored for 4 days , the rate of piped eggs was significantly (P<0.05) increased to the treatment 4 hours pre-incubated x 12 days storage compared to most others treatments. The percentage of hatched chicks its have the navel type A significantly (P<0.05) increased for the treatment 4 hours × 4 days compared to the treatment 12 hour × 12 days , while significantly (P<0.05) decrease the percentage of hatched chicks type navel B for treatment 0 hour × 4 days compared to the treatment 12 hour × 12 days , either quality type C It has significantly (P<0.05) decreased for both treatments 4 hour ×4 days and 4 hour ×8 days compared to the treatment 12 hour × 12 days

This study has been carried out to determined the prevalence rate of cryptosporidiosis in broiler flocks. 150 fecal samples from 30 broiler flocks (5 samples for each flock) in different areas of AL-Qadisiyah province were used. They were collected starting of January till November 2016 with two age groups of chickens, (10-15 and 30-35) days old. Samples were examined with Modified Ziel -Neelsen stain to detect the positive samples by microscopic examination. After that, a nested-PCR technique was performed on 60 samples. Results of microscopic examination showed that total infection rate of Cryptosporidium was 29.33% . The highest rates of infection were recorded in 10-15 days group and during spring season, infection rates reached were 35.71% and 34.28% respectively. The lowest rates were observed in 30-35 days group and during summer season were 23.75% and 20% respectively. No significant differences within percentage in both two age group or among percentage in seasons at level (P < 0.05) were recorded. According to Nested Polymerase Chain Reaction test, the results showed that overall percentage of infection is 20%. The highest rate of observed infection is 23.33% in 10-15 days aged group, while the lowest rate of infection is (16.67 %) in the other age. No significant differences was observed between percentage in ages. On the other hand, result of comparing nested-PCR test with microscopic examination shows that there are no significant differences between the percentage of both tests.
In conclusion, cryptosporidiosis is widespread in broiler flocks in AL-Qadisiyah province, but there is no significant impact found concerning the relationship between infection rates and age of chickens or seasons of the year..

The objective of this study is to determine the effect of diet supplementation with coriander seed and rosemary leaves or a mixture for them on biochemical characteristics of blood, immune organs and bacteria count in meat of broiler carcass (colony forming unit/g). A total of 1080 broiler chicks , Ross-308 at one day old, were randomly allocated for nine treatment groups . Chicks in each treatment group were subdivided for three replicates with 40 chicks for each replicate. Chicks in the first and second treatment are fed on diet supplemented with coriander seed (0.25 % and 0.50 % ) , respectively . While, chicks in the third and fourth treatment are fed diet with rosemary leaves (0.25 % and 0.50 %) , respectively . Also, Mixed of the two medical herbs are added to fifth, sixth, seventh and eighth treatment .Whereas, chicks in the ninth treatment are fed diet without medical herbs supplementation and used as a control group. At marketing age (42d) 12 blood samples are taken to measure the total protein and glucose in serum. Also 9 birds from each treatment group are culled to determine Bursa and spleen weight. Also, the relative weight of Spleen and Bursa Index are calculated. Total bacteria count (colony forming unit(cfu)/ g )and coliform and Salmonella in each one gram of mixed meat from each treatment are recorded.
Data show that dietary treatment doesn't significantly affect the serum protein contain, relative weight of bursa and bursa index. However the dietary treatment is significantly ( p < 0.05) increases the serum glucose and spleen relative weight . Total bacteria count, coliform and salmonella count are not affected by dietary treatment.
In conclusion, diet supplementation with Rosemary or coriander seed has an effect on biochemical characteristics of blood, immune organs and bacterial count.

The aim of this study is to evaluate the possible protective effect of (toxicom) 5gkg of ration against the toxic effects of mixed mycotoxins in growing broiler chickens .Total of 75 chicks ,one week old, are divided into 5 treated groups, 15 birds for each. The first group (G1) fed a contaminated ration with mycotoxin and supplemented with toxicom 5g/kg of ration and vaccinated with Infectious Bursal Disease (IBD) vaccine at 15 and 22 days of age. The second group (G2) is fed a ration contaminated with mycotoxin and vaccinated with IBD vaccine at 15 and 22 days of age and not supplemented with toxicom. The third group (G3)is fed a commercial broiler ration and vaccinated with IBD vaccine at 15 and 22 days of age . The fourth group (G4 ) is only fed a contaminated ration with mycotoxins. The fifth group (G5) is fed a commercial broiler ration as a control group. The mycotoxins in diet is analyzed by ELISA and the level is as follows : Aflatoxin B1 0.001 mg/kg ,Dezoxivalenol 1.24 mg/kg ,Zearalenon 0.068 mg/kg ,Ochratoxin 0.005 mg/kg ,T2 toxin 0.09 mg/kg ,Fuminisen B1 0.2 mg/kg. Results showed that toxicom significantly (P<0.05) protect chicken body weight, severity of clinical signs, morbidity and mortality rate. It is concluded which produced in Vitebsk State Academy of Veterinary Medicine is protect chicken that this preparation is protect chicken bioavailability parameters in comparison with the other groups and is recommended to use it as antitoxic material Republic of Belarus.
