“…Piglets fed NC without phytase had 16% lower ATTD of P compared to PC fed pigs. Addition of phytase in NC resulted in significant increase in P digestibility in agreement with previous studies ( Zeng et al, 2015 ; Torrallardona and Ader, 2016 ; Dersjant-Li et al, 2017 ; Dersjant-Li and Dusel, 2019 ; De Cuyper et al, 2020 ). However, although NC+1,000 FTU/kg resulted to the highest ATTD of P relative to NC, this value was still lower than 65%, a maximum ATTD of P indicated by meta-analyses of phytase supplementation in pigs ( Rosenfelder-Kuon et al, 2020 ).…”

“…Supplementation of phytase doses (125 to 1,000 FTU/kg) from a mixture of bacteria of the species ( Hafnia , Yersinia , and Buttauxiella ) in low Ca and P diets had linear improvement on nursery growth and bone mineralization relative; however, there was no difference between 500 and 1,000 FTU/kg doses ( Torrallardona and Ader, 2016 ). Escherichia coli phytase fed at several doses between 0 and 1,000 FTU/kg in diet with 0.15% digestible P to nursery pigs exhibited linear and quadratic responses on growth and bone mineralization ( De Cuyper et al, 2020 ). Improvements in growth and bone mineralization in the current study and previous studies data can be ascribed to the release of phytate-bound P in the negative control diet.…”

Efficacy of Aspergillus niger phytase (ASP) was evaluated in nursery pigs fed low Ca and digestible P corn and soybean meal diet. Piglets were weaned on d 21, fed a common commercial starter diet for 7 d and assigned to pens (4 pigs/pen: 2 ♀ and 2 ♂) based on BW on d 7. Positive control (PC) and negative (NC) diets were formulated with similar energy and nutrients with exception of total Ca, total P and digestible P concentrations being 79%, 67%, and 55% that of PC diet, respectively. Two other diets were formulated by adding ASP in NC at 500 and 1,000 FTU/kg. All diets had 0.2% TiO2 indigestible marker. The diets were allocated to pens to give 6 replicates per diet and fed for 42 d. Feed intake and body weight were monitored at 14-d intervals. On d 42, 1 pig/pen close was bled and euthanized to access blood and tissue samples. Analyzed total Ca and P in NC diet was 71 and 69% of concentration in PC diet. Recovery of phytase in pelleted diets was 66.2 and 73.5% for NC+500 FTU/kg and NC+1,000 FTU/kg diets, respectively. Between d 15 to 42, pigs fed NC diet grew slower and ate less feed than pigs fed the other diets. Overall (d 0-42), phytase in NC increased (P≤0.05) ADG linearly and quadratically. On d 42, pigs fed PC, NC+500 FTU/kg and NC+1,000 FTU/kg were +6.1, +5.9 and +7.1 kg heavier (P<0.05) than pigs fed NC, respectively. Pigs fed PC and NC plus phytase exhibited higher (P=0.003) G:F relative to NC pigs between d 15 and 28. Pigs fed NC diet had lower (P<0.001) plasma P concentration, apparent total tract digestibility (ATTD) of Ca and P, metacarpal and metatarsal bones attributes than pigs fed any other diets. Supplementation of phytase in NC linearly increased (P<0.05) plasma P concentration, ATTD of Ca and P and bone attributes. Specifically, phytase increased (P≤0.025) dry weight, length, and ash weight in metacarpals and metatarsals. In conclusion, low total Ca and digestible P diet depressed growth and P utilization in piglets. Supplemental phytase improved performance in pigs fed NC linked to enhanced nutrients uptake and metabolism commensurate to pigs fed adequate total Ca and digestible P from inorganic source.

“…The quadratic increase in bone ash as phytase increased in diets is in agreement with previous data from pigs [ 44 , 45 ], and is the result of the increased ATTD of Ca and P as phytase was added to the diets. The breakpoint in the linear-plateau analysis indicates that there is no improvement in the concentration of bone ash after addition of 1,222 FTU/kg.…”

Background The effect of microbial phytase on amino acid and energy digestibility is not consistent in pigs, which may be related to the phytase dosage or the adaptation length to the diet. Therefore, an experiment was conducted to test the hypotheses that increasing dietary phytase after an 18-day adaptation period: 1) increases nutrient and energy digestibility; 2) increases plasma P, plasma inositol, and bone ash of young pigs; and 3) demonstrates that maximum phytate degradation requires more phytase than maximum P digestibility. Results Data indicated that increasing inclusion of phytase [0, 250, 500, 1,000, 2,000, and 4,000 phytase units (FTU)/kg feed] in corn-soybean meal-based diets increased apparent ileal digestibility (AID) of Trp (quadratic; P < 0.05), and of Lys and Thr (linear; P < 0.05), and tended to increase AID of Met (linear; P < 0.10). Increasing dietary phytase also increased AID and apparent total tract digestibility (ATTD) of Ca and P (quadratic; P < 0.05) and increased ATTD of K and Na (linear; P < 0.05), but phytase did not influence the ATTD of Mg or gross energy. Concentrations of plasma P and bone ash increased (quadratic; P < 0.05), and plasma inositol also increased (linear; P < 0.05) with increasing inclusion of phytase. Reduced concentrations of inositol phosphate (IP)6 and IP5 (quadratic; P < 0.05), reduced IP4 and IP3 (linear; P < 0.05), but increased inositol concentrations (linear; P < 0.05) were observed in ileal digesta as dietary phytase increased. The ATTD of P was maximized if at least 1,200 FTU/kg were used, whereas more than 4,000 FTU/kg were needed to maximize inositol release. Conclusions Increasing dietary levels of phytase after an 18-day adaptation period increased phytate and IP ester degradation and inositol release in the small intestine. Consequently, increasing dietary phytase resulted in improved digestibility of Ca, P, K, Na, and the first 4 limiting amino acids, and in increased concentrations of bone ash and plasma P and inositol. In a corn-soybean meal diet, maximum inositol release requires approximately 3,200 FTU/kg more phytase than that required for maximum P digestibility.

“…Bone parameters can be quantified and analysed, enabling conclusions to be drawn about the organism and its life circumstances (Mullender et al 1996;Doube et al 2011;Chirchir et al 2017;Tsegai et al 2018). As bone mineralization and bone microstructure are dependent on nutrient intake (Scholz-Ahrens & Schrezenmeir 2007;De Cuyper et al 2020), a fluctuating food availability across seasons could result in detectable changes in squirrel bones.…”

Sciurus vulgarisLinnaeus, 1758, the red squirrel, is a small, mostly arboreally living rodent, spread across the Palearctic. It is mostly vegetarian, feeding on plants, fungi and seeds, and is less active in the winter months, but does not hibernate. In this lateral study, the humeri of the subspeciesSciurus vulgaris fuscoater, the Central European red squirrel, were analysed to uncover potential intraspecific variation between individuals found in different seasons.The µCT-scans were obtained with a resolution of 26 microns. Five bone parameters were calculated and statistically evaluated with regards to seasonal variations: total volume, bone volume, endocortical surface, cortical thickness, and average trabecular thickness.Bone volume, trabecular thickness and endocortical thickness correlate with bone size, whereas cortical thickness does not. Seasonal differences were observed between the warmer summer and autumn months versus the colder winter and spring months for all parameters. We, speculatively, relate the observed seasonal variation to nutrient intake, notably calcium. These results offer a deeper understanding of intraindividual variation in red squirrels, that may be useful in further ecological, taxonomic, and paleontological research.
