The effects of yeast derivatives and adult cecal droppings on growth parameters and intestinal morphology in commercial broilers
… alone or in combination effected performance or gut morphology of broilers during a mild coccidia challenge. Day-old Cobb 500 chicks were placed in floor pens on litter seeded with coccidia and fed diets with or without yeast products. The objectives of the second and third studies were to 1) …

An Evaluation of Corn and Sorghum as a Winter Food Source for Ring-necked Pheasants
… diets of com and/or sorghum to pheasants. 1be gut morphology and body condition of 110 pen-reared hen pheasants fed ad libitum and restricted (112, 147, 173 kcal/bird/day) corn and sorghum diets were evaluated in the winters of 1990-91 and 1991-92.Durinq the same winters, in eastern south …

Impact of intestinal bacteria on the anatomy and physiology of the intestinal tract in the PRM/Alf mouse model
Introduction: Intestinal bacteria influence gut morphology by affecting epithelial cell proliferation, development of the lamina propria, villus length and crypt depth [1]. Gut microbiota-derived factors have been proposed to also play a role in the development of a 30 % longer intestine, that is …

A Forty-Nine Day Evaluation of Bio-Mos® Replacement of Roxarsone in a Commerically Based Broiler Feeding Program
… of roxarsone and Bio-Mos® on broiler production, gut morphology and bone strength. Three thousand and ten broilers were randomly assigned to 1 of 5 dietary corn-soybean meal based treatments: 1) negative control (NEG), basal diet; 2) positive control (POS; NEG + 27 ppm Bacitracin MD); 3) roxarsone …

The Effects Of Microencapsulated Vitamin And Trace Mineral Premixes And Red Osier Dogwood Extract On Growth Performance, Immune Response, And Gut Health Of Broiler Chickens In A Coccidiosis Vaccine Challenge Model
… need for nutritional strategies to support gut health and immunity of broiler chickens. This thesis investigated the effects of two distinct dietary feed additives on growth performance, nutrient digestibility, immune response, and meat yield during a coccidiosis vaccine challenge using a …

Select novel carbohydrates affect glycemic and insulinemic response, energy value, and indices of gut health as measured using canine, avian, rodent, and in vitro model systems
… decrease cecal Escherichia coli concentrations. Gut histomorphology was positively affected by SFD and SCF. Increased crypt depth, goblet cell numbers, and acidic mucin were observed in both the cecum and colon of rats supplemented with SFD, SCF, and Pectin. These novel, low-digestible …

Nutritional control of gene expression, larval development and physiology in fish
… of development of external sensory organs, gut morphology and relevant digestive enzymes under controlled conditions using electron microscopy, histology and spectrophotometric assays. The developmental sequence of larval cobia could be separated in two phases, with a transition period …

Investigating the morphological adaptations and fungal associations of the small hive beetle, Aethina tumida Murray (Coleoptera: Nitidulidae)
… aimed towards improving our understanding of SHB morphology and associated fungal communities to gain a better understanding of how these beetles protect themselves, exploit honey bee food stores, and maintain their associated fungal communities. This study found no significant differences in …

Reducing crude protein levels in diets fed to young pigs to optimize growth performance and intestinal health
… diarrhea (PWD), blood characteristics, gut morphology, and products of protein fermentation. Both experiments used the same formulation of 3 corn-soybean diets to generate 3 experimental treatments: 3 diets contained 22% and 19% CP that provided amino acids (AA) at the requirement, and …
