Phytate and other nutrient components of feed ingredients for poultry

Abstract

Samples of feed ingredients were collected from poultry feed mills in the United States and Canada: corn (133), soybean meal (114), corn distillers dried grains with solubles (DDGS; 89), bakery by-product meal (95), wheat (22), wheat middlings (31), canola meal (21), and wheat shorts (15). The samples were assayed by standard wet chemical techniques for CP, fat, neutral detergent fiber (NDF), acid detergent fiber, calcium, phosphorus, phytate phosphorus, and ash. There was considerable variation found in most of the ingredient components. Forty-two of the 64 CV were above 10.0%. The calcium contents of the ingredients were the most variable, followed by the fat contents. The CP contents were the least variable. There were some fairly consistent relationships observed across samples; in general, acid detergent fiber and NDF were positively correlated, as were ash and mineral levels. Crude protein and fiber levels were positively related, except for wheat shorts, but the relationships were not strong. Phytate P was found to be positively related to ash and total P, as expected, except for corn DDGS. The fat content of corn was found to be negatively related to the NDF content. Significant (P < 0.004) linear regressions were found between phytate P and total P for corn, soybean meal, bakery by-product meal, wheat, wheat middlings, and wheat shorts. The average nonphytate P content of the ingredients was 49.8%, ranging from 38.8% for wheat middlings to 73.2% for DDGS. The phytate P content of wheat and wheat by-products could be predicted from their proximate compositions, with coefficients of determination in excess of 0.740. Predictions for the other ingredients were not as good.

Effect of Phytase Treatment on Phosphate Availability in the Potential Food Supplement Corn Distillers’ Grains with Solubles

“…The phytic acid concentration in corn distillers' grains with solubles has been reported to be 0.257% in a prior investigation [29]. In this study, the phytic acid content of the corn distillers' grains with solubles was found to range from 0.220% to 0.255% which is very similar to the value determined in the previous study [29].…”

Initially, the effect of treating the grains with solubles with 2 or 4 units of fungal phytase activity per g of grains with solubles was explored relative to temperature and compared to untreated samples of corn distillers' grains with solubles.…”

Amino acids digestibility of pelleted microparticle protein of fish meal and soybean meal in broiler chickens

“…The differences in results between fish meal and soybean meal is assumably due to the presence of phytate component such as oligosaccharide and anti-trypsin in soybean meal. The inferior results found for soybean meal was seemingly attributable to the presence of phytate compound (Banaszkiewicz, 2011;Tahir et al, 2012), non-protein soluble component such as oligosaccharide (Kocher et al, 2002;Oliveira and Stein, 2016), and trypsin inhibitor (Banaszkiewicz, 2011;Pacheco et al, 2013). Phytate compound in soybean meal has been reported to be varied with the range of betwen 1 and 1.5% (Banaszkiewicz, 2012).…”

Utilization of Phytase to Overcome Phytic Acid in Broiler Diet

“…Bahan pakan berasal dari hasil samping proses penggilingan biji-bijian tanaman serealia, termasuk pula bungkil, dilaporkan mengandung asam fitat lebih tinggi dibandingkan dengan biji legum (Steiner et al 2007). Tahir et al (2012) melaporkan bahwa kandungan asam fitat dalam beberapa bahan pakan yang sering digunakan sebagai bahan pakan penyusun ransum unggas adalah sebagai berikut, jagung (0,186%), bungkil kedelai (0,395%), distiller's dried grains with solubles (DDGS) (0,257%), tepung limbah roti (0,192%), gandum (0,251%) dan tepung kanola (0,695%). Dedak padi termasuk bahan pakan yang mengandung asam fitat tinggi.…”
