Effect of in ovo-delivered prebiotics and synbiotics on lymphoid-organs’ morphology in chickens
Prebiotics and probiotics, either alone or together (synbiotics), can influence the intestinal microbiota and modulate the immune response. We aimed to investigate the effects of prebiotic and synbiotic administration during the early stage of development on the histological structures of central (... Continue reading...

Antioxidative effect of ginseng stem-leaf saponins on oxidative stress induced by cyclophosphamide in chickens
Previous investigation demonstrated that oral administration of ginseng stem-leaf saponins in chickens could enhance the immune response. The present study was designed to evaluate the effects of ginseng stem-leaf saponins on oxidative stress induced by cyclophosphamide in chickens. One hundred and... Continue reading...

Efficacy of a novel prebiotic and a commercial probiotic in reducing mortality and production losses due to cold stress and Escherichia coli challenge of broiler chicks
Prebiotics consisting of resistant starch may alter intestinal ecology, thus modulating inflammation and increasing intestinal health through increased cecal production of short-chain fatty acids (SCFA). Probiotics may directly alter the intestinal microbiome, resulting in the same effects. We... Continue reading...

Use of yeast cell wall extract as a tool to reduce the impact of necrotic enteritis in broilers
The use of a yeast cell wall extract derived from Saccharomyces cerevisiae (Actigen®) has been proposed as an alternative to in-feed antibiotics. This experiment was conducted to investigate the efficacy of yeast cell extract as an alternative to zinc bacitracin or salinomycin using a necrotic... Continue reading...

Efficacy of beer fermentation residue containing Saccharomyces cerevisiae cells for ameliorating aflatoxicosis in broilers
This study aimed to determine the aflatoxin B1 (AFB1) binding capacity of a beer fermentation residue (BFR) containing Saccharomyces cerevisiae cells, and the efficacy of BFR to ameliorate the toxic effects of AFB1 on performance, serum biochemistry, and histology of broilers. The BFR was collected... Continue reading...

Effects of Clostridium butyricum on growth performance, antioxidation, and immune function of broilers
To investigate the effects ofClostridium butyricum on growth performance, antioxidation, and immune function of broilers, 320 one-day-old Arbor Acres commercial male chicks were assigned to one of 5 treatments with 8 replicates in a completely randomized design for 42 d. The 5 treatments were basal... Continue reading...

Growth promoting effects of prebiotic yeast cell wall products in starter broilers under an immune stress and Clostridium perfringens challenge
This study was designed to investigate the growth promoting effects of supplementing different sources and concentrations of prebiotic yeast cell wall (YCW) products containing mannanoligosaccharides in starter broilers under an immune stress andClostridium perfringens challenge. Through a series... Continue reading...

Effect of multi-enzymes in combination with a direct-fed microbial on performance and welfare parameters in broilers under commercial production settings
The objective of this study was to determine the response of broilers to the combination of multi-enzymes and direct-fed microbial (DFM) under commercial production settings. A total of 7,000 1-day-old male broilers (Ross 308) were distributed over 10 pens (700 broilers/pen). Two dietary treatments... Continue reading...

Prophylactic administration of a combined prebiotic and probiotic, or therapeutic administration of enrofloxacin, to reduce the incidence of bacterial chondronecrosis with osteomyelitis in broilers
Bacteria entering the bloodstream via translocation from the gastrointestinal tract spread hematogenously and can trigger bacterial chondronecrosis with osteomyelitis (BCO) by infecting osteochondrotic microfractures in the epiphyseal-physeal cartilage of the proximal femora and tibiae. In... Continue reading...
