Nutrient composition of individual feed ingredient in mixed feed is important for accurate formulation of animal feeds. However, each feed ingredient can be different depending on its origin. Therefore, this study was conducted to investigate the variability in nutrient compositions of corn, wheat, and barley grains from different origins. Cereal grains used in this study were from 5 countries ...

This review focuses on phytase functionality in the digestive tract of farmed non-ruminant animals and the factors influencing in vivo phytase enzyme activity. In pigs, feed phytase is mainly active in the stomach and upper part of the small intestine, and added phytase activity is not recovered in the ileum. In poultry, feed phytase activities are mainly found in the upper part of the digestiv...

The rapid growth of aquaculture and the lack fish meal demand new sustainable ingredients. Although fungal biomass is found to be a promising feed supplementation candidate, characteristics this protein-rich source are closely influenced by quality applied medium. In work, nutritional properties pure filamentous provided from cultivation Aspergillus oryzae, Neurospora intermedia Rhzopus oryzae ...

A large part of the environmental impact of animal production systems is due to the production of feed. Insects are suggested to efficiently convert feed to body mass and might therefore form a more sustainable food and/or feed source. Four diets were composed from by-products of food manufacturing and formulated such as to vary in protein and fat content. These were offered to newly hatched Ar...

Bovine Spongiform Encephalopathy (BSE, Mad cow disease) is generally considered to be caused by recycling animal by-products as ingredient in animal, especially ruminant, feed. Feed bans were enforced to minimize the risk on infections, and monitoring programs are effectuated for controlling the ban. The only official detection method is visual (microscopic) examination of the presence of prima...
