Abstract: The aim of this study was to investigate the occurrence and distribution of Salmonella in commercial layer farming environments of 26 flocks belonging to seven egg businesses (free-range and barn-laid) in Western Australia (WA). Between November 2017 and June 2018, a total of 265 environmental s les of dust, feed, water, pooled feces, and boot swabs were tested for detection of Salmonella according to standard culture-based methods. Isolates were assayed for serovar and subtyped by multilocus sequence typing (MLST). Salmonella spp. were recovered from 35% (93/265) of all tested s les. Dust (53.8%, 28/52) and pooled fecal (54.5%, 18/33) s les provided the highest Salmonella recovery rates. Nine different Salmonella serovars were characterized across the positive (n = 93) environmental s les, of which S. Typhimurium (60/93, 64.5%) and S. Infantis (21/93, 22.5%) were the most prevalent. MLST revealed that all S. Typhimurium isolates were of sequence type ST-19. Microbiological screening of Salmonella was not routinely practiced in any of the surveyed egg businesses. Some of the egg businesses exhibited variable levels of compliance with basic biosecurity measures as well as high-risk egg handling practices. Egg businesses in WA should be encouraged to adopt a voluntary program of environmental s ling and verification testing for Salmonella. Such voluntary programs will aid in supporting solutions for the management of this pathogen in the human food chain.

Abstract: This study was conducted in the Poultry farm technical-Agriculture research center in Salah Aldeen to investigate amla and green tea extract effect to product performance and some blood parameters on Japanese quail. In total, 300 17 weeks old quail birds were used in this study and were randomly distributed into four treatments (three replicate each treatment (n=25). The treatment groups were control (basal diet) without supplement, 1% green tea extract (GT 1%), 1% amla (AM 1%) and 1% mixed (GT+AM 1%) respectively. The results show that amla extract improved egg production significantly (P≤0.05) compared to control. The egg weight and egg mass were not significant (P .05) between each group. Amla aqueous extract (1%) shows a significant difference in feed intake as compared to the control. Hematology traits revealed a significant increase in Red Blood Cell (RBC) and hemoglobin (Hb) in green tea and amla extracts compared with control and a significant difference was observed between the aqueous extract groups and control in PCV % value. The results showed that there are no significant differences between treatments in each of Total Protein, Albumin and Globulin, but the results indicated a significant decrease (P .05) of Triglyceride, Cholesterol and Glucose, in the treatments of amla and green tea aqueous extract compare the control treatment.

Abstract: The study objectives were to evaluate effects of zinc oxide nanoparticles (ZnO NPs) on growth rate, gut histomorphology, and physiological parameters of broilers. A total 360 birds were randomly assigned into five groups (n = 72 birds per group four replicates per group n = 18), the control group drink water without nano zinc, and ZnO NP groups added 6, 8, 10, and 12 mg/liter to drinking water. The results presented that ZnO NP groups showed significant ( p 0.05 ) in growth performance with reduced feed intake in all ZnO NP groups in comparison to the control at 35 and 42 days of age. Villus height and villi to crypt ratio showed significant differences (p .05) in all ZnO NP groups compared to the basal control, but the results showed there was no significant difference (p .05) between the ZnO NP and control in crypt depth. There was no significant effect of ZnO NP on total protein and albumin in broiler serum compared to the control at 35 and 42 days of age. The data showed that ZnO NP had a positive effect and improved the ratio of serum globulin and globulin to albumin compared to the others of broilers at 35 and 42 days of age. On the other hand, liver enzyme activity was significantly ( p 0.05 ) different in ZnO NP groups compared to the basal control. The inclusion of ZnO NPs in drinking water significantly improved growth performance and gut histomorphology, and it had an impact on antioxidant and biochemical parameters.

Abstract: In recent years, the number of human salmonellosis cases in Western Australia (WA) has increased more dramatically than in any other Australian state. In 2017, the number of cases in WA was more than double the five-year average, and eggs had emerged as the key culprit for several Salmonella foodborne disease outbreaks. To better understand such an epidemiologically intriguing situation, our research goal was to investigate the prevalence, serovar ersity, multilocus sequence types, and antimicrobial resistance of non-typhoidal Salmonella contamination in retail eggs produced and sold in WA. A total of 200 visually clean and intact retail egg s les (each containing a dozen eggs) were purchased for one year (2017-2018) from supermarkets in metropolitan Perth, the capital of WA. For each s le, the contents and shells of the 12 eggs were separately pooled and cultured according to standard methods. Overall, Salmonella was detected in 11.5% (23/200) of the tested egg s les. Salmonella was isolated from 4.5% (9/200) and 3% (6/200) of eggshells and egg contents, respectively. In 4% (8/200) of the s les, Salmonella was recovered from both eggshell and egg contents. Isolates from positive retail egg s les were serotyped as either S. Typhimurium (52.2% [12/23]) or S. Infantis (39.1% [9/23]). Both serotypes were concurrently recovered from two different retail egg s les. We retained a set of both S. Typhimurium (n = 29) and S. Infantis (n = 12) isolates from all Salmonella-positive retail packs (n = 23) for further characterization. Only two (S. Typhimurium) isolates showed resistance to icillin, of which one carried β-lactamase resistance gene bla
