“…Microbial phytase can be added to diets to increase availability of phytate bound P. The most common microbial phytase used in swine and poultry diets are from fungi (Aspergillus niger and Peniophora lycii) and bacteria (Escherichia coli) [22]. The activity of phytase depends mainly on pH, temperature, dose, and diet composition [24][25][26][27]. Phytase supplementation has mostly been studied in monogastric animals, and improvement of the P digestibility has been observed in Animal production for efficient phosphate utilization Kebreab, Hansen and Strathe 873 [33,34] poultry [21,28 ] and swine [22,29].…”

Phosphorus (P) is an essential nutrient for livestock but its efficiency of utilization is below 40%, contributing to environmental issues. In this review, we summarize recent approaches to optimize P availability in livestock diets and improve its utilization efficiency. Phase feeding could potentially reduce P excretion by 20%. Addition of phytase enzymes to diets increased P availability from 42 to 95%. Low phytate transgenic plants and transgenic animals increased P availability by 14% and 52-99%, respectively. In practice, a combination of phase feeding and enzymes has the highest potential for P reduction but legislation and ethics implications will prevent using transgenic animals in the short term. Functional and nutritional genomics may provide tools to improve efficiency in the future.

Advances and Future Directions in Poultry Nutrition: An Overview

In the past, poultry nutrition has focussed on increasing the production efficiency to meet the progress achieved in the genetic potential of broilers and layers. Future directions in poultry nutrition will be driven by not only by the need to maximise biological and economic performance of birds, but also by societal issues (environment, antibiotic growth promoters, welfare, traceability and use of genetically modified ingredients). Key advances in poultry nutrition are discussed and future directions, which can be expected, are highlighted. Given the tightening supply and ever-increasing cost of raw materials, there will be more pressure to extract every unit of energy and nutrients from feed ingredients. In this context, a number of feed additives are expected to play an increasingly significant role. Feed enzymes and crystalline amino acids, in particular, will have a profound effect on future sustainability of the poultry industry. Future nutritional research need to focus on identifying the barriers to effective digestion and utilisation of nutrients and, to achieve this objective, nutritionists must combine their expertise with those of specialising in other biological sciences, including immunology, microbiology, histology and molecular biology.

“…Keuntungan suplementasi fitase dalam dosis tinggi, memiliki implikasi tidak hanya untuk kinerja pertumbuhan ternak semata, tetapi juga untuk kesehatan ternak, serta memiliki pengaruh positif pada kualitas daging dan telur (Cowieson et al 2011). Efek positif yang ditimbulkan tersebut terjadi akibat: (1) Pelepasan mineral dari kompleks fitat-mineral; (2) Pemanfaatan inositol oleh anak ayam; (3) Peningkatan daya cerna pati; dan (4) Peningkatan daya cerna protein (El-Husseiny et al 2006;El-Deek et al 2009).…”

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...
