Poultry gut health
The efficient conversion of feed into its basic components for optimal nutrient absorption is vital for both broiler and broiler breeder production and welfare. Gut health, an intricate and complex area combining nutrition, microbiology, immunology and physiology, has a key role to play. When gut health is compromised, digestion and nutrient absorption are affected which, in turn, can have a detrimental effect on feed conversion leading to economic loss and a greater susceptibility to disease. In addition, recent changes in legislation on the use of antimicrobials, differing feed requirements and more efficient birds highlight the need for a better understanding of gut function and gut health.
Introduction The poultry industry has experienced unprecedented growth in the past 70 years due to improved genetics, nutrition, housing, water quality and veterinary care driven by post-WWII consumer demands (Havenstein, et al., 2003). Modern-day poultry efficiently convert feed to meat and eggs, but genetic selection for improved performance may have inadvertently selected for a negative correlative response to other traits such as immune function (Cheema et al., 2003). The reader...

Introduction Blackhead disease, also known as Histomoniasis, is an important poultry disease caused by Histomona meleagridis, which is a protozoa that spreads in the bird by the roundworm Heterakis gallinarum, and infects the cecum and liver. Turkeys are highly susceptible to this disease. Although mortalities in turkey flocks reach 80-100% and economic losses exceed 2 million USD/year, there are lack of approved drugs against blackhead disease. Therefore, phytogenic compounds...

An experiment was conducted to determine the effects of corn particle size (CPS) on turkey hen performance, intestinal permeability (IP), and litter dry matter. Hybrid turkey hens were housed in floor pens from 0 to 42d. Hens were fed a crumbled starter 1 (0 to 21d) and pelleted starter 2 (22 to 42d) diet. The experiment was a 2 x 2 factorial with diet phase (starter 1 and starter 2) and CPS (fine or coarse), resulting in 4 treatments of 18 replicates of 22 turkeys. Corn was manufactured...

INTRODUCTION Production of broilers with high growth rate and feed efficiency through impressive genetic improvement is often directly linked with digestive problems, such as passage of undigested feed (or) feed passage syndrome with impaired gut health function. The passage of undigested feed inside the poultry house is a sporadic problem in integration or individual farms mainly during rainy season. This may be due to the limited availability of major raw materials in diet and...

The overuse of antibiotics has led to the development of antibiotic-resistant bacteria in poultry production. However, there are some additives, like probiotics and prebiotics, which can be used as alternatives to reduce the need for antibiotics. In that sense, how can we determine if feed additives are helpful for birds? Simply put, maintaining a healthy gut is crucial for the overall well-being of poultry, since it leads to better growth and immunity. That means that developing models to...

Vaccination against coccidiosis is on the rise. It is supported by a growing societal demand for antibiotic-free meat products. However, vaccination may be accompanied by some adverse effects, such as a negative impact on growth and/or the development of necrotic enteritis. Moreover, during the time of the establishment of immunity, the birds are only moderately protected. In this study, we investigated different strategies of associating cocci vaccination and a mixture of saponin plants...

The objective of this study was to evaluate the impact of an Eastman monoglyceride blend on broiler performance under a 25-day necrotic enteritis challenge model in battery cages. A total of 320 one-day old male Cobb broilers were obtained from a local hatchery and randomly distributed into 4 groups with 10 chicks per cage and 8 replicates per treatment: (1) non-challenged control (NCC); (2) challenged control (CC); (3) challenged control + 500 mg/kg monoglyceride blend (low-dose); (4)...
