“…The primary purpose for including phytase in broiler diets is to liberate phytate-bound P [20]. 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.…”

“…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. Truong, et al [21] reported that phytase (1000 FTU/kg) increased apparent disappearance rates of phytate in four small intestinal segments which indicates that phytase has the capacity to degrade phytate and generate "phosphoric responses" in sorghum-based diets. Thus phytase inclusions in sorghum-based diets have the potential to reduce levels of inorganic P source and reduce feed costs but the "extra-phosphoric" responses may be somewhat muted.…”

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.

“…Phytase has been shown to improve ileal Na digestibility coefficients in broilers or, in the main, reduce the extent to which these values are negative Selle et al, 2009). More recently, Truong et al (2014) reported highly negative Na digestibility coefficients in the proximal jejunum which became progressively less negative along the small intestine which demonstrates that phytase enhanced Na absorption. That total tract Na retention was positive in the present study suggests further recovery of Na was taking place in the large intestine.…”

Phytic acid has been considered as an antinutrient in broiler diet due to its strong chelator of divalent minerals. Phytic acid has ability for binding positively charged proteins, amino acids, and/or multivalent cations or minerals. The resulting complexes are insoluble, difficult to be hydrolyzed during digestion in poultry, and thus, nutritionally less available for absorption. The reduction of phytate activity can be carried out by phytase supplementation. The application of phytase with respect to animal feed supplement is reviewed in this paper. Application of phytase in broiler diet may liberate cations and other nutrients bound by phytate-P complexes resulting in improved production parameters in broilers. This is because phytase supplement increased nutrient (protein, minerals, amino acid, energy, and carbohydrate) digestibilities and availabilities. Overall, phytase could increase nutrient utilization in broiler, hence, increase the economic efficiency of broiler production and reduce the phosphor pollution to the environment. Key words: Phytic acid, phytase, broiler, growth ABSTRAKAsam fitat dianggap sebagai zat antinutrisi dalam ransum ayam pedaging karena mampu mengikat mineral bervalensi dua, disamping zat gizi lain seperti protein atau asam amino. Hasil pengikatan asam fitat dengan zat gizi menyebabkan zat gizi tersebut tidak dapat dicerna dalam saluran pencernaan ayam sehingga menurunkan tingkat ketersediaan untuk metabolisme dalam tubuh ayam pedaging. Penanganan zat antinutrisi asam fitat dapat dilakukan melalui suplementasi fitase ke dalam ransum. Beberapa studi menunjukkan bahwa suplementasi fitase ke dalam ransum ayam pedaging mampu meningkatkan pertumbuhan karena meningkatnya kecernaan zat gizi (protein, asam amino, energi, karbohidrat dan mineral) dalam usus. Penggunaan enzim fitase dalam ransum ayam pedaging juga meningkatkan efisiensi ekonomi dan menekan cemaran fosfor terhadap lingkungan. Kata kunci: Asam fitat, fitase, ayam pedaging, pertumbuhan PENDAHULUANPenambahan bahan sumber fosfor ke dalam ransum ayam pedaging akan menyebabkan sebagian besar dari fosfor tersebut terekskresikan melalui feses dan akan menyebabkan pencemaran air dan tanah, terutama ketika feses tersebut dimanfaatkan sebagai pupuk (Toth et al. 2006;Costa et al. 2008;Guo et al. 2009). Dampak negatif bagi lingkungan tersebut jika tidak dikendalikan akan berdampak negatif pula terhadap sektor peternakan karena dianggap sebagai sumber pencemaran lingkungan sehingga suatu waktu dapat dipolitisasi sebagai dasar dilakukannya tekanan terhadap sektor peternakan untuk menghentikan aktivitas peternakannya.Upaya pengurangan jumlah bahan pakan sumber fosfor yang digunakan dalam ransum ayam pedaging penting dilakukan karena akan mengurangi pengeluaran fosfor lewat feses sehingga akan menekan pencemaran lingkungan oleh fosfor yang berasal dari feses. Strategi dalam upaya untuk menekan pencemaran fosfor terhadap lingkungan dari cemaran fosfor yang terkandung dalam feses ternak ayam atau ternak monogastrik adalah melalui penin...
