“…The piglet stomacal pH is generally higher than in the gizzard (Lé tourneau-Montminy, 2009;Schlegel et al, 2010), and piglets seem not capable to release a significant amount of native Zn from phytates. The capacity of broilers to release native Zn from phytates would also explain the 8 times lower Zn equivalence of supplemental phytase (500 FTU/kg diet) in broilers compared with the equivalence in piglets (Jondreville et al, 2005 and2007) also when the capacity of supplemented phytase to hydrolyze PP is similar between the two species Ravindran 2007 andLé tourneau-Montminy et al, 2010 and2012). It is also in accordance with the lower Zn requirements in this species compared with piglets (National Research Council 1994 and.…”

Zinc (Zn) is essential for swine and poultry and native Zn concentrations in feedstuffs are too low to meet their Zn requirement. Dietary Zn bioavailability is affected by phytate, phytase and Zn supplemented in organic form is considered as more bioavailable than inorganic sources. A meta-analysis using GLM procedures was processed using broiler and piglet databases to investigate, within the physiological response of Zn, (1) the bioavailability of inorganic and organic Zn sources (Analysis I); (2) the bioavailability of native and inorganic Zn dependent from dietary phytates, vegetal and supplemental phytase activity (Analysis II). Analysis I: the bioavailability of organic Zn relative to inorganic Zn sources ranged, depending on the variable, from 85 to 117 never different from 100 ( P . 0.05). The coefficients of determination of the regressions were 0.91 in broilers and above 0.89 in piglets. Analysis II: in broilers, bone Zn was explained by supplemental Zn (linear and quadratic, P , 0.001) and by supplemental phytase (linear, P , 0.001). In piglets, the interaction between dietary Zn and phytates/phytases was investigated by means of a new variable combining dietary phytic phosphorus (PP) and phytase activity. This new variable represents the remaining dietary PP after its hydrolysis in the digestive tract, mainly due to phytase and is called non-hydrolyzed phytic phosphorus (PP NH ). Bone Zn was increased with native Zn ( P , 0.001), but to a lower extent in high PP or low phytase diets (ZN N 3 PP NH , P , 0.001). In contrast, the increase in bone zinc in response to supplemental Zn ( P , 0.001) was not modulated by PP NH ( P . 0.05). The coefficients of determination of the regressions were 0.92 in broilers and above 0.92 in piglets. The results from the two meta-analyses suggest that (1) broilers and piglets use supplemented Zn, independent from Zn source; (2) broiler use native Zn and the use is slightly enhanced with supplemental phytase; (3) however, piglets are limited in the use of native Zn because of the antagonism of non-hydrolyzed dietary phytate. This explains the higher efficacy of phytase in improving Zn availability in this specie.

“…More farm-specific models of P utilization and P stored in soil are necessary to evaluate the local impact of phytase on EP. However, further improvement in modeling P in livestock systems such as those presented by Létourneau-Montminy et al (2010) and Symeou et al (2014) is expected to improve estimates of the impact of phytase on EP and AP depending on input data availability. Greater use of renewable energy sources in the production of SFI is expected to reduce PED, and it is considered an area where the industry could take action.…”

Livestock production has a variety of environmental impacts such as greenhouse gas emissions, water pollution, acidification, and primary energy consumption. The demand for livestock products is expected to grow substantially, creating even more environmental pressure. The use of specialty feed ingredients (SFI) such as supplemented AA and phytase can reduce nutrient input into the system without compromising productivity and consequently can reduce emissions. The global change impact of using SFI in pig and broiler production systems in Europe and North and South America was studied. A life cycle assessment according to international standards (ISO 14040/44) analyzed contributions from producing SFI and animals to global change. Three different alternatives were analyzed. In addition, partial sensitivity analysis was conducted using 5 scenarios for each region for both production systems. Specialty feed ingredient supplementation in pig and broiler diets reduced greenhouse gas emissions (cradle to farm gate) by 56% and 54% in Europe, 17% and 15% in North America, and 33% and 19% in South America, respectively, compared to an unsupplemented diet. A total of 136 Mt CO 2 equivalent (CO 2 eq) was saved in 2012, rising to 146 Mt CO 2 eq in 2050 on the basis of United Nations population projections. Considerable benefits of supplementation with SFI were apparent in European and South American diets when direct land use change was considered because of the reduced demand for soybean meal. The eutrophication potential of unsupplemented diets was reduced by up to 35% in pig and 49% in broiler production systems compared to supplemented alternatives. The acidification potential of supplemented strategies was reduced by up to 30% in pig and 79% in broiler production systems. The primary energy demand was similar in all alternatives, and this could be an area where the SFI industry can improve. Overall, SFI supplementation substantially reduced the global warming, eutrophication, and acidification potentials in all regions studied.

“…This may be related to the lower electrolytic capacity of divalent ions compared with monovalent ions or because of the presence of a relationship between Ca and P, as shown here. A relationship between Ca and P is known in relation to bone deposition, where both minerals are required for bone mineralization and a shortage of one mineral may result in losses of the other (Létourneau-Montminy et al, 2010). Fecal P content has been shown to rapidly increase when optimum tibia ash content is reached (Waldroup et al, 2000).…”

High litter moisture content, often referred to as wet litter, is a major problem in poultry production. Wet litter is often related to poor management, diseases, and digestive problems. In this experiment, the objective was to study the relationship between nutrient content and the moisture content of the excreta of broilers. A dataset containing 351 observations was built and contained the nutrient contents data including moisture content of excreta samples collected in 8 different broiler feeding trials. A biological based model approach was used to create a model with 10 and another one with 14 variables that may explain the excreta moisture level response. Subsequently, these models were compared with a statistical model that was built automatically and adjusted only if this improved the biological model. The R 2 of the 10 variable model was 0.54, in which Zn content and the interaction of NDF × K and Ca × P content were negatively associated with excreta moisture. Sodium, P, and Ca content and the interaction between content of NDF × Na were positively associated with excreta moisture. The R 2 of the 14 variable model was 0.58, in which Zn and K content and the interaction of NDF × protein and Ca × P content were negatively associated with excreta moisture, and Na, protein, P, and Ca content and the interactions in contents of NDF × Na, NDF × Zn, and K × Cu were positively associated with excreta moisture content. In conclusion, the models confirmed the effect of Na, protein, P, and Ca on excreta moisture content. Furthermore, hitherto unknown nutrient interactions that contribute to excreta moisture level were identified. As excreta levels of most nutrients can be manipulated by adjusting dietary nutrient levels, dietary formulation can be adjusted with the findings of this analysis to change levels of excreted nutrients and, consequently, also moisture output.
