Iohexol-based assessment of intestinal permeability in broilers challenged with , or both.

Impaired intestinal integrity in broilers reduces performance and health, highlighting the importance of accurately measuring intestinal permeability (IP) to maintain gut health. The objective of this study was to evaluate the efficiency of iohexol as an IP marker in broilers challenged with , , or both during both peak challenge (day [d] 21) and recovery (d 28) periods. One-day-old male Ross 708 birds (n = 56) were distributed into 4 treatment groups: NC (no-challenge control); EM (challenged with 5,000 .

Positive impact of dietary marine sulfated polysaccharides derived from macroalgae during a necrotic enteritis challenge.

Caused by the Gram-positive bacteria Clostridium perfringens, necrotic enteritis (NE) is an enteric disease with significant economic implications in broiler production. This study employed an experimental NE model involving co-infection with Eimeria maxima and C. perfringens to assess whether sulfate polysaccharides extracted from marine macroalgae could mitigate the adverse effects of NE in broilers.

Impact of early postbiotic supplementation on broilers' responses to subclinical necrotic enteritis.

Necrotic enteritis (NE), an enteric disease caused by Clostridium perfringens, results in damage to the intestinal epithelial lining disrupting its function, nutrient absorption, and utilization. This study evaluated the effects of in ovo and post-hatch applications of a Saccharomyces cerevisiae-based postbiotic on performance and nutrient transporter genes of broilers during a NE challenge. At embryonic d 18, Ross 708 fertile eggs were injected with 0.

Evaluating performance, intestinal lesions, and immunity related genes in heritage and modern broiler breeds during a necrotic enteritis challenge.

In this comparative study, the differential responses of heritage (ACRB; Athens Canadian Random Bred) and modern (Cobb) broilers to a necrotic enteritis (NE) challenge were evaluated. The design was a 2×2 factorial with breed (ACRB and Cobb) and challenge (non-challenged and NE-challenged) as main factors. On day (d) of hatch, 96 male chicks (48 ACRB and 48 Cobb) were allocated to 4 experimental groups with 8 replicate cages and 3 birds/cage.

Auditory brainstem response findings in autism spectrum disorder speech delay population.

Objectives: Evaluate pediatric auditory brainstem response (ABR) findings in children with Autism Spectrum Disorder (ASD) after the 2013 DSM-5 update.

Study Design: This was an IRB-approved, six-year retrospective chart review evaluating ABR results from pediatric patients with speech delay. Diagnosis of ASD and other neurodevelopmental abnormalities were collected for patient stratification.
