An increase in dietary phytate concentration may limit the availability of both phosphorus (P) and calcium (Ca) as a result of the progressive formation of Ca-phytate complexes along the gastrointestinal tract (Selle et al., 2009). However, inconsistent results were reported regarding the impact of phytate on P and Ca release in the presence of phytase with broilers, presumably due to the differen ...

Mycotoxins are secondary metabolites produced by fungi, the most abundant of which belong to the genera Aspergillus, Penicillium, and Fusarium. The conditions required for fungal development and the production of mycotoxins vary strongly with the substrate on which the fungal species develop.Because mycotoxins are mainly present in food and feed, the gut is the first target for mycotoxin toxicity, ...

IntroductionHeat stress (HS) is one of the most challenging environmental stressors despite the modern climate control equipment in broiler chickens’ houses. Broiler flocks may be seasonally exposed to HS that varies in intensity according to the relative humidity of the region [1]. Multiple studies have identified the various adverse effects of acute or chronic HS on chickens, such as a sev ...

1 IntroductionAmino acids are organic compounds containing both amino (—NH2) and carboxyl (—COOH) groups. Due to the presence of asymmetric carbon, all amino acids except glycine exhibit optical activity and exist as D- and L-isoforms or enantiomers (Lehninger et al., 2005). The asymmetric α-carbon imparts chirality, a phenomenon where the molecule is not superimposable to its mi ...

Pressure on feed cost is and will remain a decisive factor for profitability and sustainability in pork and poultry production. In the backdrop of soaring inflation, other production costs have escalated. Corollary minimizing the costs associated with production has never been of greater importance. Arguably, feed formulation is a precise science that seek to compute combination of feedstuffs to m ...

    A 41-d floor pen experiment was conducted to evaluate the effects of supplementing higher doses (up to 3 times the standard dose of 500U) of phytase (CIBENZA® PHYTAVERSE®, Novus International, Inc.) in broiler chicks fed non-phytate phosphorus (NPP) deficient corn-SBM based diets. A total of 1584 Ross 308 male broiler chicks were assigned to 6 treatments with 12 pens/trea ...

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 ...

The objective of this study was to evaluate if the supplementation of guanidinoacetic acid (GAA) either on top or included with an energy matrix in broiler feed, improves or equalizes the productive and economic parameters in broilers, respectively. The study was carried out in an experimental farm located in the department of Santander-Colombia and lasted 34 days. A total of 1088 Ross 308 AP day- ...
