Dietary inclusion of phytase and stimbiotic decreases mortality and lameness in a wire-ramp challenge model in broilers
Avian Pathol. 2024 May 22:1-47. doi: 10.1080/03079457.2024.2359592. Online ahead of print.ABSTRACTAbstractLameness due to bacterial chondronecrosis with osteomyelitis (BCO) is an infection of weak bone by opportunistic bacteria that infiltrate the circulation as a result of immune suppression or gastrointestinal deterioration. One mitigating strategy is the dietary inclusion of products to support overall broiler robustness and bone health. To test the ability of phytase and stimbiotic supplements to alleviate lameness, broilers were reared for 56 days on either litter flooring or wire ramps to induce BCO and fed one of 6 ...

Quantification of the effect of vaccination on the control of horizontal transmission of < em > Mycoplasma synoviae < /em > under field conditions
In this study the effect of MS live vaccination on horizontal transmission was quantified under field conditions by analysing four-year MS monitoring data from non-MS-vaccinated broiler and layer breeders and MS-vaccinated broiler breeders with good biosecurity in single-age housing systems. Flocks were monitored at 20 and 30 weeks of age and every 12 weeks thereafter. Every sampling sixty blood samples or 24 tracheal swabs were tested using rapid plate agglutination test and ELISA serially or MS DIVA PCR respectively. The MS incidence rate was calculated and the association with vaccination was analysed by logistic regres...

Genomic characterization of infectious bursal disease virus in Argentina provides evidence of the recent transcontinental spread of Chinese genotype A2dB1b
Avian Pathol. 2024 May 14:1-20. doi: 10.1080/03079457.2024.2355918. Online ahead of print.ABSTRACTThe infectious bursal disease virus (IBDV) is a significant pathogen affecting the poultry industry worldwide. Its epidemiological history has been marked by the emergence of strains with different antigenic, pathogenic, and genetic features, some of which have shown notable spread potential. The A2dB1b genotype, also known as novel variant, has become widespread and gained increased relevance in IBDV epidemiology. This genotype was described in China in the 2010s and rapidly spread in Asia and Africa. The present study descri...

Intestinal microbiota diversity from broilers with runting and stunting syndrome performed by metagenomics
This study aimed to investigate the compositional changes in the bacterial community of the ileum of 7-day-old broiler chicks naturally affected and not affected by RSS, using next-generation sequencing (NGS) technology. Twenty-one samples were obtained from the ileal contents and mucosa of 11 chicks with RSS and 10 healthy chicks, raised in a dark house system located on a farm in the state of Minas Gerais, Brazil. The results revealed overall changes in the gut microbiota of the chicks with RSS, including a decrease in microbial richness and diversity. In particular, there was a decrease in Lactobacillus and an increase ...
