1. Introduction Genetic selection for production traits, to meet increased requirements for chicken meat, has been applied to broiler chickens at an unprecedented rate (Siegel, 2014; Tixier-Boichard et al., 2012; Zuidhof et al., 2014). Such an emphasis on productive traits may have compromised the ability of modern broilers to cope with metabolic and skeletal disorders (Dawkins and Layton, 2012; ...

Introduction Dietary arginine supplementation higher than the recommended levels was shown to improve broiler performance (Murakami et al. 2012; Xu et al., 2018; Zampiga et al., 2018). It suggests that arginine levels needed for maximum performance could be higher in modern broilers, which is probably related to the several functions of arginine on animal metabolism. Besides, arginine enhances th ...

Introducción Quantitative genetic selection, using a weighted index of economically important traits, has been used by commercial breeders for over 60 years to improve the performance of egg-type stocks.  That selection has been made primarily on BW, feed conversion (FC), egg number, egg size, various measurements of interior and exterior egg quality, and income over feed and chick co ...

The more divalent cations in the diet the less soluble phytate becomes. This is especially true when drinking water pH is high and when phytate concentration is also high. In diets with high concentrations of e.g. Ca (from limestone, drinking water Ca, inorganic P sources, vegetable sources, V&M premix etc), high phytate concentration and more alkaline drinking water then the need for superdosin ...

Background The avian ceca generally have a more important role in digestion than the cecum in most mammals. Avian ceca are usually finger-shaped blind pouches, presenting as lateral extensions at the junction of the small and large intestine and are commonly present in pairs. In birds the ceca vary considerably in size and morphology; ranging from very long, such as in most domestic poultry, to c ...

Some producers complain that their meat or egg type chickens suffer from problems in bone or egg shell quality when they include phytase in the diet as a partial substitute for the inorganic phosphorus sources (MCP; DCP; bone meal) according to the matrix value provided by the manufacturing company. Under field conditions, phytase activity is controlled by several par ...

Excellent article,covering in quite simply way all aspects of phytates /phytase /phosphorus. I like it very much. Just some additional words. 1.phytase unit: there is more than one unit name and value.The registration conditions (eg.pH 5,5, temp 37C, 1 min....) are same but other factors (the buffer, colorant, etc in lab conditions) are different. Eg.one unit FTU (Du Pont) is not equall to FYT (DS ...
