Spray-dried plasma (SDP) contain immunoglobulins and glycoproteins that possess antibacterial properties. Two floor-pen trials were conducted to determine the efficacy of dietary SDP and bacitracin methylene disalicylate (BMD) antibiotic in reducing intestinal colonization by Salmonella Enteritidis (SE) in broiler chickens. Experiment 1 was a 2-wee...

Broiler embryonic development depends on the nutrients that are available in the egg, which includes mostly water, lipids, and proteins. Carbohydrates represent less than 1%, and free glucose only 0.3%, of the total nutrients. Considering that energy requirements increase during incubation and metabolism is shifted toward the use of glycogen stores...
Article
Locally grown feed ingredients of high energy and protein content, such as peanuts, maybe economically feasible alternatives to corn and soybean meal in broiler diets. Even though normal-oleic peanuts have been demonstrated to be a viable feed ingredient for poultry, few studies to date have examined the use of high-oleic peanuts (HO PN) as an alte...

Early feeding trials using peanut meal prepared from normal-oleic peanuts helped to identify peanuts as a suitable alternative feed ingredient for poultry. Yet no studies to date have examined the use of high-oleic peanuts (HO-PN) as a feed ingredient for meat type chickens. Therefore, this study aimed to determine the effect of feeding whole unbla...
Article
Previous studies have demonstrated that allergenic feed proteins from peanuts in the diets of layer hens are not detected in the eggs produced. Hence, in this study, we aimed to determine if soy and/or peanut proteins in poultry feed rations of broiler chickens or layer hens would be transferred or detectable in the meat or eggs produced. To meet t...

Previous studies have identified peanut meal prepared from normal-oleic peanuts as a suitable and economical ingredient for broiler feed. However, to date, no studies have examined the use of new, high-oleic peanut (HO-PN) cultivars as a feed ingredient for poultry. This project aimed to determine the effect of HO-PNs as a feed ingredient for broil...

The history of the feed industry is pertinent in terms of understanding how and why certain practices have evolved. Some of these practices have been superseded by modern, more natural alternatives, for example the traditional use of antibiotics in feed. In other cases, such as inorganic minerals, more natural versions akin to those found in plant...

Anti-nutritional factors (ANFs) in feed ingredients can challenge gut health and reduce nutrient utilization. Birds typically activate their innate immune system as a protective response against the adverse effects of ANF, which often involves the secretion of mucin. Although dietary supplementation of exogenous enzymes are commonly used to allevia...

Although dietary inclusion of corn distillers dried grains with solubles (DDGS) in turkey diets may be cost effective, it increases the amount of non-starch polysaccharides, such as water-insoluble arabinoxylans, which compromises nutrient digestibility but may also serve as fermentation substrate for commensal microflora.

Accessory to Obesity? Melanocortin receptors are a family of cell membrane receptors that control diverse physiological functions. Mutations in the gene encoding melanocortin 4 receptor (MC4R) are a cause of familial early-onset obesity. Asai et al.

β-mannanase is an enzyme that reduces the anti-nutritional effects of β-mannan in the diet of poultry by hydrolyzing the β -1, 4 glycosidic bonds of mannan into smaller, less viscous mannan oligosaccharides. Soybean meal (SBM) protein and hulls, typically included in poultry feeds, contain a significant amount of β-mannan, thus dietary supplementat...
