“…Lizardo et al (2015) observed that increasing the Buttiauxella phytase dose up to 2000 FTU/kg improved dry matter (DM) and nitrogen (N) digestibility in growing pigs, while Amerah et al (2014) reported that supplementation of Buttiauxella phytase at 1000 FTU/kg improved ileal AA digestibility on average by 10% in broilers. Similarly, with the same phytase, improvements in starch and protein digestibility were found in broilers (Liu et al, 2014Truong et al, 2015). Bento et al (2012) reported that increasing Buttiauxella phytase dose up to 2000 FTU/kg not only improved apparent total tract digestibility of P and Ca, but also linearly improved DM digestibility in weaned piglets.…”

“…Liu et al (2014) observed that addition of Buttiauxella phytase at dose of 1000 FTU/kg improved weight gain, feed intake and feed efficiency in corn, wheat or sorghum based diets in broilers. However, phytase addition to corn-based diets generated more pronounced responses in weight gain and feed conversion ratio (kg feed/kg BW gain, FCR) compared to sorghum or wheat based pelleted diets.…”

SummaryThe effect of a Buttiauxella phytase, in a dose range of 0-1000 FTU/kg in feed, on production performance in growing/finishing pigs fed European type wheat, corn, barley and SBM based diet was determined. Five dietary treatments were tested including a positive control (PC), a negative control (NC) without inorganic P and with reduced Ca (-0.12%) and metabolisable energy content (-0.14 MJ ME/kg) or NC supplemented with Buttiauxella phytase (Axtra ® PHY, Danisco Animal Nutrition, DuPont Industrial Biosciences, Marlborough, UK) at 250, 500 or 1000 FTU/kg respectively. A total of 100 pigs (mean initial BW of 30 kg, Topig x Pi, 10 weeks of age) were used, with 20 replicates per treatment (50% gilts and 50% barrows). Pigs were individually housed in pens and randomly allocated on the basis of body weight (BW) and gender to the five treatments. Feed, in mash form, and water were offered ad libitum. Basal diets had an intrinsic phytase level of approximately 300 and 440 FTU/kg in NC grower and NC finisher diets respectively. Mean average daily gain (ADG), average daily feed intake (ADFI) and feed conversion ratio (FCR) were calculated for the feeding phases of 30-85 kg (grower), 85-125 kg (finisher) on trial and for overall period. During the grower phase, increasing phytase dose resulted in a linear increase in ADG. Phytase inclusion at 250, 500 and 1000 FTU/kg improved ADG by 3.5, 7.2 and 8.1% respectively compared to NC and by 0.8, 4.5 and 5.3% respectively compared to those fed the PC. Performance in the finisher phase, overall period and slaughter parameters were not different between dietary treatments. The data showed that it was beneficial to increase phytase dose up to 1000 FTU/kg in grower pigs up to 85 kg BW. In the finisher phase, in pigs with BW above 85 kg, 500 FTU/kg was sufficient to replace inorganic P and maintain performance and carcass characteristics comparable to pigs fed the PC.

“…Phytase significantly increased average starch digestibility coefficients by 7.27% (0.812 versus 0.757; p < 0.04) in the four small intestinal sites. Subsequently, Liu, et al [7] showed that there were numerical improvements in weight gain, feed conversion efficiency and N retention in sorghum-based diets following phytase supplementation (1000 FTU/kg). Truong, et al [93] found that phytase did not significantly influence nutrient utilisation and apparent digestibility of starch and nitrogen along the small intestine in birds offered sorghum-based diets.…”

“…This "phosphoric effect" of phytase in sorghum-based diet is in evidence as Truong, et al [21] reported that phytase significantly increased apparent disappearance rates of phytate in the proximal jejunum, distal jejunum, proximal ileum and distal ileum in boilers. Also, Liu, et al [7] showed that phytase significantly increased toe ash from 11.68% versus 12.29% in broiler chickens offered sorghum-based diets. However, the "extra-phosphoric" responses to phytase sorghum-based diets often appear to be muted.…”

Grain Sorghum: A Conundrum for Chicken-Meat Production

Abstract:The inclusion of grain sorghum in diets for broiler chickens is quite common; however, under Australian conditions, the utilisation of starch/energy by birds offered sorghum-based diets appears inadequate. Various factors inherent in sorghum, including kafirin, phenolic compounds and phytate, may limit energy utilisation. The recent quantification of kafirin, the dominant protein fraction in sorghum, has allowed its nutritional significance to be assessed. This is important as indirect evidence suggests that kafirin concentrations in local sorghums are increasing as an unintended consequence of breeding programs. Presently, Australian sorghums do not contain condensed tannin but, from analyses and assessments of other polyphenolic compounds and phenolic acids, "non-tannin" phenols appear to be negative influences. Anecdotally, white sorghums are considered to be superior to red varieties thus the fact that polyphenolic pigments are responsible for the "redness" of sorghum assumes relevance. Inclusions of sulphite reducing agents in broiler diets have generated promising responses but seem dependent on sorghum properties. Preliminary studies have shown the possibilities of using rapid visco-analyser (RVA) starch pasting OPEN ACCESSAgriculture 2015, 5 1225 profiles, promatest protein solubilities and grain textures to indicate sorghum quality and further studies are required to confirm these hypotheses. These assessments may indicate which sorghums will best respond to reducing agents such as sodium metabisulphite. Finally, the usually modest responses of broilers to exogenous feed enzyme inclusions in sorghum-based are considered in this review.

“…KLEYN (2013) notes that phytase has an impact mainly on the anti-nutritional properties of PP, and that, although not directly measurable, may have a positive effect on the performance of the birds due to a better absorption of the other nutrients. In addition, PP present in wheat is located in the aleurone and due to its fibrous nature it ends up limiting the access of the phytase to its substrate, thus stopping PP degradation (LIU et al, 2014).…”
