Zinc is an essential element, a cofactor of many enzymes, and performs catalytic, structural and regulatory functions. Once in the gastrointestinal tract, zinc can interact with food constituents. Phytic acid, the major phosphorus storage in plants, limits zinc availability from animal feeds due to the formation of insoluble complexes with phytates. This study tested the effect of supplemental zinc source (zinc sulfate and a chelate zinc proteinate) and the addition of exogenous enzymes from a solid-state fermentation product of Aspergillus niger to a high phytate diet. The study was designed according to three Latin Squares 4 × 4 with a 2 × 2 factorial arrangement of treatments, with four periods, four diets, and 12 young adult Beagles. Periods lasted 5 weeks each. Diets were supplemented with 75 mg/kg of zinc sulfate (IZ) or zinc proteinate (OZ), and without or with 200 mg/kg of exogenous enzymes (IZ+, OZ+). Results showed that zinc proteinate increased the bioavailability of phosphorus, yet the zinc biomarkers remained unaffected by the zinc source, with the exception of lymphocyte subsets that benefit from zinc proteinate. The use of exogenous enzymes did not affect zinc availability nor nutrient and energy digestibility.

“…Phytase (myoinositol hexakis [dihydrogen phosphate] phosphohydrolase, EC 3.1.3.8) is the enzyme that catalyzes the sequential release of orthophosphate groups from the inositol ring of PA to produce free inorganic phosphorus, minerals and/or proteins, with a chain of intermediaries myoinositol phosphates (inositol pentaphosphate to inositol monophosphate) [7]. Monogastric animals (dogs, pigs, and poultry) cannot metabolize phytate (IP6) as they produce low amounts of endogenous phytases [8]. Due to this, inorganic phosphate (Pi) is supplemented in the diets of these animals to meet their nutritional requirement.…”

Partial characterization and purification of phytase from Lactobacillus plantarum CRL1964 isolated from pseudocereals

Cereals and pseudocereals are a rich source of nutrients and trace elements, but their dietary bioavailability is low due to the presence of phytate (IP6), an antinutritional compound with the ability to chelate cations and proteins. Phytase is an enzyme that catalyzes the hydrolysis of IP6 and it is used as an additive improving the nutritional quality of grain‐based foods. The aim of this study was to select lactic acid bacteria (LAB) isolated from pseudocereals with phytase activity, characterize their production and activity, and purify the enzyme. LAB strains isolated from grains and spontaneous sourdough of quinoa and amaranth were grown in the Man Rogosa and Sharpe medium where the inorganic phosphate (Pi) was replaced by 1% of IP6. Phytase activity was determined by measuring the Pi released from IP6. Phytase of Lactobacillus (L.) plantarum CRL1964 (PhyLP) showed the highest specific activity from 73 LAB evaluated. IP6 induces PhyLP production, which is at its maximum at the end of the exponential phase. PhyLP was thermostable and maintained its activity under acidic conditions. The enzymatic activity is stimulated by ethylenediaminetetraacetic acid, Co2+, and ascorbic acid. PhyLP was partially purified and showed a molecular mass of 55 kDa. L. plantarum CRL1964 and/or PhyLP have the potential to be included in the processing of cereal/pseudocereals based products for animal feed and/or the food industry improving its nutritional value.

“…Thus, if in one hand, the use of nutritional techniques and technologies can bring a benefit in terms of reducing the costs of animal feed (Boyd et al, 2018;Sitanaka et al, 2018), on the other hand, they can interfere in the chemical composition of the manure (Caniatto, 2011;Cowieson et al, 2016), and consequently, in the manure logistical and distribution costs.…”

Animal production systems and agribusiness Full-length research article How can nutritional strategies and feed technologies in pig production affect the logistical costs of manure distribution? ABSTRACT-The objective with this study was to evaluate the impact of different swine nutritional strategies and technologies, as well as the land spread system, on logistical costs of pig manure distribution. For this, pigs were fed a conventional diet (C0) or a diet supplemented with 0.01% phytase (C1); organic minerals (40% substitution; C2); synthetic amino acids at reduced dietary crude protein levels (C3); or a combination of the three strategies (C4). All pig manure was weighed, then its chemical composition was determined. The mineral values and volume of manure produced were extrapolated to corresponding pig farm sizes in Sao Paulo state (300, 650, and 1000 sows) from real pig manure levels to produce simulations. To determine the logistical cost of manure distribution, two distribution systems were considered: vacuum tank tractor and vacuum tank truck (4.30 and 15 m³, respectively). The land spread truck system had the highest cost/hour worked due to the higher fuel consumption. However, this cost might be different over greater distances. Manure production, as well as the nutrient levels of N, P, and K, were lower for swine fed diets supplemented with nutritional technologies. Therefore, the different nutritional technologies reduced the transportation and distribution cost of pig manure by reducing the area and, consequently, the distances that need to be traveled for distribution. However, from an agronomic point of view (i.e., to meet a crop fertilization demand per hectare), manure from pigs fed diets supplemented with nutritional technologies had a higher application rate on land.
