SummaryAmmonia production in commercial poultry sheds poses a problem for farmers as high levels can affect animal's respiratory health, resulting in hock and foot pad lesions and thereby affecting performance. A study was conducted to evaluate the suitability of whole, chopped and dried Yucca schidigera (De-Odorase™, Alltech Inc, USA) to reduce ammonia excretion from broilers and investigate the impact on broiler performance. Nine hundred and two, one-day-old Cobb broilers were randomly assigned to one of two diets, without (control) or supplemented with 500 g/t De-Odorase™. Birds fed the treatment diet had significantly higher body weight (P < 0.05) at 42 d and improved FCR (P < 0.05). Significant reductions in ammonia from litter were reported at 37 and 42 days old (P < 0.05 and P < 0.1, respectively). No significant differences were seen in foot pad, gait score, feather score or carcass data; although the birds fed De-Odorase™ had consistent numerical improvements in these parameters. The results of this study suggest that feeding whole, chopped and dried Yucca schidigera as a functional ingredient in the diet can be part of an ammonia management programme to improve broiler welfare and zootechnical performance.

ABSTRACT While measures to control carcass contamination with Salmonella at the processing plant have been implemented with some success, on-farm interventions that reduce Salmonella prevalence in meat birds entering the processing plant have not translated well on a commercial scale. We determined the impact of Salmonella vaccination on commercial poultry operations by monitoring four vaccinated and four nonvaccinated breeder (parental) chicken flocks and comparing Salmonella prevalences in these flocks and their broiler, meat bird progeny. For one poultry company, their young breeders were vaccinated by using a live-attenuated Salmonella enterica serovar Typhimurium vaccine (Megan VAC-1) followed by a killed Salmonella bacterin consisting of S. enterica serovar Berta and S. enterica serovar Kentucky. The other participating poultry company did not vaccinate their breeders or broilers. The analysis revealed that vaccinated hens had a lower prevalence of Salmonella in the ceca (38.3% versus 64.2%; P < 0.001) and the reproductive tracts (14.22% versus 51.7%; P < 0.001). We also observed a lower Salmonella prevalence in broiler chicks (18.1% versus 33.5%; P < 0.001), acquired from vaccinated breeders, when placed at the broiler farms contracted with the poultry company. Broiler chicken farms populated with chicks from vaccinated breeders also tended to have fewer environmental samples containing Salmonella (14.4% versus 30.1%; P < 0.001). There was a lower Salmonella prevalence in broilers entering the processing plants (23.4% versus 33.5%; P < 0.001) for the poultry company that utilized this Salmonella vaccination program for its breeders. Investigation of other company-associated factors did not indicate that the difference between companies could be attributed to measures other than the vaccination program.

The intensification in aquaculture production leads to increasing attention on the management of ammonia from its waste. Natural solutions such asYucca schidigeraextracts have shown beneficial effects. Their origin (harvested from the wild), however, call for alternative and equally efficient solutions in order to increase the sustainability of their production. In this work, juvenile Nile tilapias (Oreochromis niloticus) were supplemented with different doses of a commercial mixture of saponin-rich plants (Norponin® OPTI, CTL: 0ppm, D1: 100ppm, D2: 500ppm and D3: 2500ppm). The impact on water quality was monitored, with a particular attention to total ammonia excretion (TAN). TAN was significantly reduced in treatments D1 and D2 compared to the control and D3 treatments (p<0.05). Overall, the present study demonstrates that a supplementation with low doses of the feed additive (100 or 500ppm) induced beneficial effects on TAN management.

Salmonella is a foodborne pathogen commonly associated with poultry products. The aims of this work were to 1) estimate the impact of critical steps of the slaughter process on Salmonella detection from broiler chicken carcasses in two commercial poultry slaughter plants in Quebec, Canada, 2) investigate the presence of the pathogen in the slaughter plant environment, 3) describe, using a high resolution melting (HRM) approach, the HRM Salmonella profiles and serotypes present on carcasses and in the slaughter plant environment and 4) evaluate if the HRM flock status after chilling could be predicted by the flock status at previous steps of the slaughter process, or by the status of previous flocks, or by the status of the processing environment, for a same HRM profile. Eight visits were conducted in each slaughter plant over a 6-month period. A total of 379 carcass rinsates from 79 flocks were collected at 5 critical steps of the slaughter process. Environmental samples were also collected from seven critical sites in each slaughter plant. The bleeding step was the most contaminated with &gt;92% of positive carcasses. A decrease of the contamination along the slaughtering process was noted, with carcasses sampled after dry-air chilling showing ?2.5% Salmonella prevalence. The most frequently isolated serotypes were S. Heidelberg, S. Kentucky and S. Schwarzengrund. The detection of the S. Heidelberg 1-1-1 HRM profile on carcasses after chilling was significantly associated with its detection at previous steps of the slaughter process and in previously slaughtered flocks during a same sampling day. Results highlight the importance of the chilling step in the control of Salmonella on broiler chicken carcasses and the need to further describe and compare the competitive advantage of Salmonella serotypes to survive processing. The current study also illustrates the usefulness of HRM typing in investigating Salmonella contamination along the slaughter process.

The exploration of novel nonantibiotic interventions in the field, such as the use of bacteriophages, is necessary to avoid the presence of Salmonella. Bacteriophages are a group of viruses widely distributed in nature, strictly associated with the prokaryotic cell. Researchers have demonstrated the success of phage therapy in reducing Salmonella counts in poultry products. However, the impact that phage concentration in the environment may have against certain Salmonella serovars is not well understood. Therefore, the aim of this study was to assess Salmonella phage prevalence in commercial poultry farms in terms of the production type: layers or broilers. The most prevalent Salmonella serovars isolated in poultry production were used for phage isolation. Salmonella specific phages were isolated from 141 layer and broiler farms located in the Valencia region during 2019. Analysis of the samples revealed that 100% presented Salmonella phages, the most prevalent being against serovar S. Enteritidis (93%), followed by S. Virchow (59%), S. Typhimurium (55%), S. Infantis (52%) and S. Ohio (51%). These results indicate that poultry farms could represent an important source of Salmonella phages. Nevertheless, further studies are needed to assess the epidemiology of phages against other serovars present in other countries and their diversity from the point of view of molecular studies.

The impact of breastfeeding on respiratory health is uncertain, particularly when the mother has asthma. We examined the association of breastfeeding and wheezing in the first year of life.We studied 2773 infants from the Canadian Healthy Infant Longitudinal Development (CHILD) birth cohort. Caregivers reported on infant feeding and wheezing episodes at 3, 6 and 12 months. Breastfeeding was classified as exclusive, partial (supplemented with formula or complementary foods) or none.Overall, 21% of mothers had asthma, 46% breastfed for at least 12 months and 21% of infants experienced wheezing. Among mothers with asthma, breastfeeding was inversely associated with infant wheezing, independent of maternal smoking, education and other risk factors (adjusted rate ratio (aRR) 0.52; 95% CI 0.35–0.77 for ≥12 versus <6 months breastfeeding). Compared with no breastfeeding at 6 months, wheezing was reduced by 62% with exclusive breastfeeding (aRR 0.38; 95% CI 0.20–0.71) and by 37% with partial breastfeeding supplemented with complementary foods (aRR 0.63; 95% CI 0.43–0.93); however, breastfeeding was not significantly protective when supplemented with formula (aRR 0.89; 95% CI 0.61–1.30). Associations were not significant in the absence of maternal asthma (p-value for interaction <0.01).Breastfeeding appears to confer protection against wheezing in a dose-dependent manner among infants born to mothers with asthma.

BACKGROUND: Inconsistent operational definitions during asthma surveillance can lead to inaccurate estimation of disease burden and formulation of health policy. This study aimed to evaluate the impact of different definitions on the prevalence estimates and predictors of asthma among university students in Ilorin, Nigeria. The secondary aim was to compare level of agreement of the different definitions.METHODS: This cross-sectional study was carried out from June to August 2015. The European Community Respiratory Health Survey (ECRHS) questionnaire was self administered by 1485 students. Asthma diagnosis was based on five definitions used in previous studies in the country. These were ECRHS, International Study of Asthma, Allergies in Childhood (ISAAC), Probable, Modified ECRHS and Modified Probable asthma definitions.RESULTS: The prevalence rates varied from 10.4 to 24.1% depending on the definition. Prevalence obtained by using ECRHS definition significantly differed from estimates by other definitions (Z score ≥ 1.96 p<0.0001) except modified probable asthma. Identified predictors of asthma varied from five to six depending on the definition, and their strength also differed by definition. Regardless of the definition, reported nasal allergy, skin allergy, family history of nasal allergy, asthma and parental smoking were the predictors of asthma. The Kappa statistics demonstrated a fair to almost perfect association between the ECRHS and other asthma definitions (Kappa = 0.334-0.841, p < 0.001).CONCLUSION: The prevalence rates and predictors of asthma are affected by operational definitions. Researchers need to adopt a uniform definition for accurate estimation of disease burden, international comparison of result and formulation of prevention policy.

THE EFFECT OF PARTLY SUBSTITUTION OF DIET WITH WHITE CHINESE CABBAGE (Brasscia pekinensia L) WASTE PRODUCT ON BIOLOGICAL PERFORMANCE OF BROILER CHICKEN The present study was conducted to characterize the effect of white Chinese cabbage (Brasscia pekinensia L) waste product as an alternative feed source for broiler chicken.  The experiment was conducted at Faculty of Animal Husbandry’s experimetal station for 21 days using 60 MB-202 broiler chicken. The experiment was started at 21 days of age and terminated at 42 days of age. Birds were allocated to 20 experimental battery cage, 3 birds in each cage. Completely Randomized Design (CRD) with 5 treatments and 4 replications was employed to analyze experimental data. Treatment diets were formulated as follow: R0 = 100% basal diet and 0% white Chinese cabbage waste product; R1 = 95% basal diet and 5% white Chinese cabbage waste product; R2 = 90% basal diet and 10% white Chinese cabbage waste product; R3 = 85% basal diet and 15% white Chinese cabbage waste product; and R4 = 80% basal diet and 20% white Chinese cabbage waste product. Parameters measured were: 1) daily feed consumption; 2) daily gain; and 3) feed conversion ratio (FCR). The results of the study during which feed consumption (138,09-141,57g), weight gain (64,95-68,53g), and feed conversion (2,07-2,12). The results showed that partly substitution (up to 20%) of basal diet with white Chinese cabbage waste product gave non significant (P > 0.05) effect on feed consumption, daily gain, and feed conversion ratio (FCR) of broiler chicken. It can be concluded that white Chinese cabbage waste product can be used up to 20% feed gives good results on broiler performance. Key Words: Substitution, white Chinese cabbage waste product, broiler performance
