Coccidiosis is one of the main challenges for the worldwide poultry industry, and several anticoccidial treatments have been used to fight these protozoa. Resistance of Eimeria parasites against anticoccidials—and the public opinion about these treatments—demands for alternatives. In this trial, we tested Yucca schidigera (500 g/T) as a natural alt...

The present study used a PCR approach to characterize prevalence of coccidial species in fecal samples obtained from 40 individual Midwestern turkey flocks to characterize distribution of species in commercial flocks. Each sample was screened for 6 prominent Eimeria species using species-specific primers and was supplemented with a primary nested-P...

The effect of Eimeria challenge on standardized ileal digestibility (SID) of amino acids (AA) in major poultry feed ingredients fed to broiler chickens was determined. A total of 840 male 9-day-old Ross 708 chicks were placed in 84 cages (10 birds/cage) and allocated to either a nitrogen-free diet (NFD) or one of the 6 test diets based on a single ...
To exploit aqueous-soluble formulation and improve the anticoccidial activity of 4,4′-dinitrocarbanilide (DNC, active component of nicarbazin), this paper prepared DNC/GA/PVP K30 solid dispersion (SD) with glycyrrhizic acid (GA) and polyvinylpyrrolidone (PVP) K30 by a mechanical ball milling method without using any organic solvent. Fourier transfo...

An anti-diclazuril monoclonal antibody (mAb) was developed for use in enzyme-linked immunosorbent assay (ELISA)-based detection of diclazuril with high sensitivity and specificity, which can be used to measure anti-coccidial drug residues. The anti-diclazuril mAb had a half-maximal inhibitory concentration of 0.449–0.517 ng/mL. The mAb cross-reacti...
The objective of this study was to evaluate the effects of dietary sulfur from either organic (methyl sulfonyl methane, MSM) or inorganic (sodium sulfate, SS) sources on the growth performance of broiler chickens challenged against a high-dose coccidiosis vaccine. A total of 320 day-old Ross 308 broiler chicks were randomly placed into 32 pens of 1...

Macrophage colony-stimulating factor-1 ( M-CSF-1 or CSF-1 ) is a hematopoietic growth factor that stimulates the survival, proliferation, and differentiation of the mononuclear phagocyte lineage and is involved in bone metabolism, fertility, pregnancy, inflammatory processes, and homeostasis. CSF-1-activated macrophages display unique features, suc...

Matrix metalloproteinases ( MMP s) are a family of proteases, that can process extracellular matrix ( ECM ) components and non-ECM molecules. MMPs can also function intracellularly in proteolytic and nonproteolytic functions. The participation of MMPs in the remodeling of the chicken gastrointestinal tract is largely unknown. The aim of the present...
The effects of chlorogenic acid (CGA) on growth performance, anticoccidial indicators (oocysts per gram of excreta, cecal lesion score, and bloody diarrhea score), immunity, antioxidant status, and intestinal barrier function in coccidia-infected broilers were investigated. A total of 240 one-day-old Arbor Acres broilers were randomly divided into ...

A systematic review and meta-analysis was conducted to investigate the role of Eimeria species, dose and inoculation time, on performance and infection outcomes of different broiler strains infected for different study durations. The meta-analysis addressed E. acervulina, E. maxima, E. tenella, and mixed species infections, and involved data from 7...
