Comparison of the Effects of Deracoxib, Buffered Aspirin, and Placebo on the Gastric Mucosa of Healthy Dogs
… (COX-2) inhibitor, would result in lower gastric lesion scores than administration of buffered aspirin and gastric lesion scores similar to placebo when administered to healthy dogs for 28 days. Twenty-four, healthy, random source dogs were divided into three groups. Group I received buffered …

The Effects of Probiotics on Performance and Immune Response of Broiler Chickens during Coccidiosis
… collected from d20-d24 for oocyst counts, and lesion scores were evaluated on d21. Data were analyzed using the Fit Model platform in JMP Pro 10.0 (SAS). Differences in experimental treatments were tested using Tukey HSD following ANOVA with significance reported at P ° 0.05. Overall, NEG birds …

Nutritional strategies to control clostridium perfringens in gastrointestinal tract of broiler chickens
… populations, α-toxin production and NE lesion scores. Majority of birds showed clinical signs of disease with 4.16-8.33% mortality. There was a direct correlation between intestinal C. perfringen populations, NE lesions scores and mortality with dietary glycine level. However, due to the …

Studies on the immunopathologic mechanisms of intestinal lesion formation in turkey poults infected with hemorrhagic enteritis virus
… enteritis virus (HEV) induces intestinal lesion formation associated with clinical infection is unknown. These studies were designed to 1) determine differences in age susceptibility to HEV infection and parameters which best indicate severity of virus infection, 2) determine the …

Performance and Microbial Profiles of Broiler Chickens fed Phytogenic Feed Additives or Probiotics during Coccidiosis
… Eimeria maxima, E. tenella, and E. acervulina. Lesion scores were assessed on d21. Body composition was analyzed via Dual Energy X-Ray Absorptiometry (DXA) on d28. Results indicated a trend (P < 0.1) toward improved D28 body composition, lower Clostridium in DFM-fed challenged broilers compared …

Managing Poultry Gut Integrity, Immunity and Microbial Balance During Necrotic Enteritis
… Supplementation of certain additives reduced NE lesion scores, improved performance and increased mRNA abundance of claudin-3, a key epithelial TJ protein. Multi-strain probiotics and multi-component additives (including a symbiotic and a product containing probiotics, prebiotics and essential …

Impact of Dietary Beta-glucan Supplementation on Performance and Immune Response of Broiler Chickens During Challenge
… were taken on d 7, 14, 21, and 28, and lesion scores assessed on d 21. The challenge resulted in reduced BW, and higher feed conversion ratio (FCR) was observed in the challenged birds with Sal and BGZn. Escherichia coli (E. coli) is normally commensal to the gastrointestinal tract, but …

Renal allograft biopsies at Groote Schuur Hospital: a histopathologic descriptive study with molecular insights
… rejection- and non-rejection pathologies, Banff lesion scores and DSA status. A computer- based tool was used on historic data to re-calculate Banff 2022 classification diagnoses, which were compared to historic diagnoses. Logistic regression assessed C4d as a predictor of DSA. Results: The …

Lung auscultation as a predictor of lung lesions and bovine respiratory disease outcome in feed yard cattle
… diagnosis of BRDC ante-mortem and respiratory lesions at slaughter. The objectives of the studies reported here were to: 1) validate a thoracic auscultation scoring system by correlating ante-mortem lung sounds with post-mortem lung lesions and 2) evaluate thoracic auscultation and rectal …

The effects of erythrocyte alloantigen L on the avian immune response
… six times over 10 weeks postinoculation. Tumor scores were used to assign a tumor profile index (TPI) to each chicken. Results were evaluated by ANOVA. The B complex affected the responses. Separate analyses revealed L system effects ( P < 0.05) only in B5B 5 chickens.</p><p>Experiment 2 …
