“…Several authors have reported an increment of Ca ATTD when the phytase enzyme has been added to the diet (Braña et al, 2006;Almeida et al, 2013) because Ca is chelated by phytic acid, regardless of its original form (Woyengo & Nyachoti, 2013). When phytase hydrolyses phytic acid, it releases the chelated Ca, making it available for the pigs to use.…”

Soybean meal (SBM) is the protein source that is used most in feeding piglets, but its high price has prompted a search for alternatives. One option is sesame meal (SM), a by-product of sesame oil. This study evaluated the effects of SM and phytase on the intestinal morphology, total trypsin activity (TTA) and specific trypsin activity (STA), apparent ileal digestibility (AID) of amino acids (AAs), and apparent total tract digestibility (ATTD) of phosphorus (P), calcium (Ca), and energy (E) in weaned piglets. Twenty piglets weaned at 17 days old were placed in metabolic cages in a temperature-controlled room. When the piglets were 21 days old, cannulas were fitted at the terminal ileum. From the fourth day after surgery, piglets received the experimental treatments for nine days, namely an SM or SBM diet, each with or without phytase. The protein source or phytase did not affect villus height, crypt depth, or TTA. However, phytase increased STA. The AID of dry matter (DM), E, crude protein (CP), and AA was similar among treatments, except for arginine, which was more digestible in the SM diets (85.8) than in the SBM ones (81.6). The ATTD of DM and E was higher in the SM than in the SBM diets. Phytase increased the ATTD of Ca (22.7 %) and P (27.9 %). The findings showed that SM can be used as a protein source for piglets and that its consumption increases arginine intake. The addition of phytase to the diet increases the ATTD of P and Ca.

“…Assuena et al (2009) melaporkan bahwa fosfor memiliki peran penting dalam tubuh ayam, yaitu berperan dalam proses metabolisme dan secara khusus berperan penting dalam pertumbuhan ayam pedaging. Hal tersebut dikarenakan secara ekonomi, fosfor merupakan zat gizi yang memiliki nilai ekonomi tertinggi ketiga dalam formulasi ransum ayam pedaging setelah energi dan asam amino sehingga perlu dioptimalkan penggunaannya (Woyengo & Nyachoti 2013). Pemanfaatan asam fitat sebagai sumber fosfor dalam ransum ayam melalui proses hidrolisis pemecahan fosfat yang terikat fitat diharapkan dapat meningkatkan efisiensi penggunaan fosfor dalam ransum.…”

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...

“…Disamping kelebihan tersebut diatas, dedak padi memiliki kelemahan yang salah satunya adalah mengandung asam fitat yang dapat mengikat mineral sehingga penyerapan mineral akan terganggu. Kandungan asam fitat dalam diet untuk babi secara umum telah terbukti menurunkan penampilannya (Woyengo and Nyachoti, 2013). Kandungan fitat dalam pakan babi biasanya antara 7 dan 10 g / kg dari diet (Selle et al, 2009;National Research Council, 2012).…”

ABSTRACT:In countries with high plant biodiversity such as Indonesia, the availability of food of plant origin is very diverse. The presence of anti-nutrients in plants would potentially cause problems in cattle if not managed properly. phytic acid is one anti nutritional factor that have a role in disrupting the health and productivity The term phytate refers to the molecule phytic acid, which generally acts as a chelate to Mg, Ca, Na, and K, and in some cases protein and carbohydrates. Seeds of cereals, legumes and oilseed plant which is used as animal feed usually contains a lot of phytic acid which can cause a decline in nutritional value. However, with a variety of processing methods, levels of phytic acid in animal feed can be reduced or even eliminated. In addition to the processing method, the method of adding phytase enzyme may also be done to improve the nutritional value of the animal feed ingredients.
