“…Supplementation of diets with microbial phytase (1000 FTU/kg) increased P digestibility by 16.3 and 13.7% in SBM and RSM diets, respectively. The equations obtained in our study have shown that the effect of both types of phytase is additive; this is in agreement with the observations of Diingelhoef et al (1994). However plant phytase was 32 and 41% less effective than microbial phytase in diets with RSM and SBM, respectively.…”

“…Apparent P digestibility coefficients for maize and barley are similar to those obtained by Jongbloed and Kemme (1990a), Wecke et al (1994) and for wheat by Jongbloed and Kemme (1990a), Berk and Schulz (1993) and BarrierGuillot et al (1996). According to Diingelhoef et al (1994) and Rodehutscord et al (1996) the digestibility of wheat phosphorus was higher (62-68%) than obtained in our study. In contrast, the digestibility of P determined in triticale was about 8% lower than cited in the literature (Berk and Schulz, 1993;Diingelhoef et al, 1994).…”

The experiment was carried out on 24 growing Polish Landrace pigs. The apparent digestibility of P from cereal grains (maize, barley, wheat, triticale, rye or mixture of barley with rye) and from diets containing cereals and 25% rapeseed meal (RSM) or 40% soyabean meal (SBM) was determined. The diets were unsupplemented or supplemented with microbial phytase (1000 FTU/kg). The digestibility of P was measured by an indirect method (with Cr 2 0 3 as an indicator) in 129 individual collections.The activity of intrinsic phytase in maize and oil meals was low (no more than 180 FTU/kg DM) and was considerably higher in other cereals (from 750 FTU in barley to 2077 FTU/kg DM in rye). The apparent digestibility of P in barley, wheat, triticale and rye did not differ between species (average 37.1%) and was about 17% percentage points higher (PO.01) than in maize.Although it was estimated that the effect of intrinsic and microbial phytase on digestibility of P was additive, plant phytase was 32 and 41% less effective than microbial phytase in diets with RSM and SBM, respectively. The intrinsic phytase content in cereal improved P digestibility in diets with RSM or SBM by 9.3-9.6% per 1000 FTU. Supplementation of diets with microbial phytase (1000 FTU) increased P digestibility by 13.7 and 16.3% in RSM and SBM diets, respectively. However, the increase in the content of digestible P by microbial phytase was similar (about 1 g/kg) in diets with both protein sources.

“…In most protein-feeds of plant origin phosphorous is poorly available for pigs due to the proportion of phytate P in feedstuffs and the lack of intrinsic phytase (Dungelhoef et al, 1994;Rodehutscord et al, 1996). Numerous reports have shown that addition of microbial phytase to pig diets can release a significant portion of the bound P, improving phosphorus availability (Nasi et al, 1995;Helander et al, 1996;Kornegay and Qian, 1996).…”

Thirty-three female pigs from 25 to 70 kg body weight were fed isocaloric and isoprotein diets composed of rapeseed (RSM) or soyabean meal (SBM) and a wheat-barley mixture with high intrinsic phytase content (over 900 FTU/kg). Basal diets containing 0.19-0.20% of digestible P were unsupplemented or supplemented with either microbial phytase (1000 FTU/kg, Natuphos®) or dicalcium phosphate to the level of 0.25% recommended for growing pigs. Apparent digestibility of nutrients, growth performance, carcass value, physical properties of the femur, third metatarsal and metacarpal and chemical composition of the whole bodies of pigs were investigated.Microbial phytase supplementation increased (P<0.01) the content of digestible P to a higher degree in the diet with RSM (0.78 g) than with SBM (0.48 g/kg), and in the empty body increased ash, calcium and phosphorus contents by 1.55, 0.58 and 0.34 g/kg, respectively. The phytase-supplemented pigs had similar Ca:P ratios as unsupplemented ones and higher (PO.01) ratios of ash and phosphorus to protein in their bodies. Growth performance, carcass characteristics, protein and energy content in the body and physico-mechanical properties of the femur and metatarsal were not MICROBAL PHYTASE FOR PIGSchanged by phytase or dicalcium supplementation, except the strength value in the third metacarpal which was higher in pigs receiving the diet supplemented with inorganic P. Utilisation of digestible P was significantly higher (85-87%) in pigs fed basal diets than in animals fed diets supplemented with microbial phytase or dicalcium phosphate (67-73%). Daily protein deposition in the body was not decreased by reducing the P content in the diet to 0.19%). RSM, as the high protein feed in the diet with barley and wheat, supplied a sufficient amount of P to cover the requirements of growing pigs. The results of the experiment indicated that cereal phytase has a beneficial effect on total phytic P utilisation.

“…The concentration of native phytase depends on the grain species and it occurs in high quantities only in some grains. Rye and triticale are high in native phytase (Düngelhoef et al, 1994;Czech and Grela, 2004;Czech, 2007), whereas wheat and barley are not so rich in this enzyme. Maize and oil industry by-products are particularly poor in endogenous phytase (Selle et al, 2000).…”

ABSTRACT:Two experiments were conducted to examine the influence of addition of microbial phytase to diets differing in native phytase content, on the performance of sows and digestibility of nutrients. Barley and wheat grains relatively poor in native phytase used in Experiment 1 mixtures were replaced by triticale and rye (rich in this enzyme) in Experiment 2 diets. There were 3 groups in each experiment. Group I (control) received basal diets enriched with dicalcium phosphate (10 g/kg), group II (negative control) was fed basal diets without any additive, and group III (negative control) was supplemented with microbial phytase (500 PU/kg). Body weights of sows were monitored at mating, before parturition, immediately after parturition and at weaning. Apparent ileal and total tract digestibility of basal nutrients, detergent fibre fractions, Ca and P of the investigated diets from particular treatments was determined. Microbial phytase (Natuphos ® , BASF AG, Ludwigshaven, Germany) supplemented at 500 PU/kg in pregnancy and lactation diets based on barley and wheat resulted in smaller body weight losses during lactation and higher weight gain over the whole cycle. Synergistic effects of microbial phytase and native phytase on body weight changes of sows, feed conversion ratio during pregnancy, and apparent (ileal and total tract) digestibility of both organic matter and minerals (total and phytic phosphorus and calcium) were found out.
