INTRODUCTIONFinishing diets are composed of about 45% to 55% starch based on typical dietary corn inclusion (Samuelson et al., 2016). While the rumen is the primary site of starch digestion, it is highly dependent on grain source, processing method, and degree of grain processing (Owens et al., 1997). Steam flaking corn usually improves cattle performance due to an increase of starc ...

INTRODUCTION The importance of nutritional management for improving production and minimizing environmental impacts from beef and dairy cattle industry is well-established (McAllister et al., 1996; Havlík et al., 2014; Bach et al., 2020). Corn grain is the most commonly used cereal grain for dairy and beef production in the United States and its high starch content yields energy to sup ...

IntroductionProtein is a major and expensive component of animal feed, accounting for about 20% of the total dry matter content of swine and poultry diets. Soybean meal is the leading source of feed protein [1]. In the gut, protein is hydrolyzed by endogenous proteases, principally pepsin (EC 3.4.23.1), trypsin (EC 3.4.21.4) and chymotrypsin (EC 3.4.21.1), releasing peptides that are processed fur ...

1. Introduction Energy intake and digestibility, particularly the energy obtained from starch, is the limiting factor for growth in feedlot beef cattle [1]. Corn is the predominant grain (dry rolled, ground, high moisture or steam flaked) and starch source used in the US, Central and Latin America feedlots [2]. Among the grain processing methods, steam flaking is an effective way to increase starc ...

For a general and quick understanding of protein-phytic acid interactions and the role of microbial phytases in hydrolyzing the phytate in such complex, please watch our 1min Youtube video: https://www.youtube.com/watch?v=IER7kauUImo

1. IntroductionPhytase is the enzyme that hydrolyzes phytic acid and its salt phytate (myo-inositol hexakisphosphate, IP6), resulting in the formation of inositol pentakis-, tetrakis-, tris-, bis- and monophosphate (IP5-IP1) in a stepwise manner and five inorganic phosphates (Pi) (Skoglund et al., 1998; Greiner et al., 2000). Inclusion of phytase in animal feed not only makes the phytate-bound pho ...

A breakthrough in our understanding of phytase enzyme mode of action and the associated matrix values in feed formulation has been provided in a recent paper published by Tran et al. in the January 2011 edition of Analytical Biochemistry entitled 'A simple and fast kinetic assay for phytases using phytic acid–protein complex as substrate'.While at first glance the relevance of the title to a ...
