Evaluation of the Effect of a Lippia organoides Essential Oil Extract on Clostridium perfringens Proliferation In Vitro and Necrotic Enteritis in Broiler Chickens
… with Salmonella Typhimurium on day 0, Eimeria maxima on day 18, and Clostridium perfringens on days 22 and 23. Treatment groups included a 1) non-challenged, negative control, 2) challenged control, and 3) challenged, Lippia origanoides (37ppm in the diet). Group 1 (negative control) …

A Forty-Nine Day Evaluation of Bio-Mos® Replacement of Roxarsone in a Commerically Based Broiler Feeding Program
… 14 replicate pens/treatment were challenged with Eimeria maxima (3 x 104 oocysts/bird). Tibias were collected on day 28 and 49 to determine bone-breaking strength. Non-challenged birds had higher body weight gains (BWG) and lower feed conversion (FCR) from day 0 to 49 than challenged birds (P < …

Cellular Events During Coccidial Infection in Chickens
… coccidiosis is caused by the intestinal protozoa Eimeria. The parasite's site of infection in the intestine is site specific. Eimeria acervulina mainly affects the duodenum, E. maxima the jejunum, and E. tenella the ceca. Lesions in the intestinal mucosa cause reduced feed efficiency and body …

The combined effects of purified fiber and dietary threonine on chick growth, and gut health, when infected with coccidiosis
… of purified fiber and dietary Thr during an Eimeria maxima coccidiosis infection. In Experiment 1, chicks received corn/soybean meal (SBM) based diets containing 7% added silica sand (control), cellulose, or high-methoxy pectin through d 14 post-hatch. Inclusion of pectin reduced (P < 0.05) …

Performance and Microbial Profiles of Broiler Chickens fed Phytogenic Feed Additives or Probiotics during Coccidiosis
… of commercial broilers fed either PFAs or Eimeria challenged broilers fed probiotics. During the probiotics study, 1056 day-old male Ross broiler chicks were assigned to one of 6 treatments, 8 replicates per treatment, with 22 birds per floor pen in a 2x3 factorial arrangement, with DFM mix …

Investigating the Potential of Microbial Metabolites and mTOR Signaling on Chicken Necrotic Enteritis
… acid (DCA). The birds were challenged with Eimeria maxima (20,000 oocysts/bird) at d 18 and C. perfringens (109CFU/bird/day) at d 23 and d 24 to induce NE. Birds were sacrificed at d 26, and ileal tissue and digesta samples were collected. DCA alleviated the subclinical NE-induced intestinal …

The Influence of Necrotic Enteritis, Environmental Factors, and Genetics on Intestinal Development Pathways and Disease Occurrence in Broiler Chickens
… the host response to infection of the parasite Eimeria maxima that predisposes chickens to a bacterial infection Clostridium perfringens. Intestinal structure, function, inflammatory response, and epithelial composition was examined during a mild subclinical infection. Analysis of E. maxima and …
