Kanatlı Hayvanların Rasyonlarında Fitaz Enzimi Kullanılmasının Önemi

Bilindiği gibi kanatlı hayvanların rasyonları büyük ölçüde bitkisel kökenli yem maddelerinden oluşmakta-dır. Bu yem maddelerindeki toplam fosforun önemli bir kısmı kanatlılar tarafından yeterince yararlanılamayan fitik asite bağlı fitat fosforu formundadır. Bitkisel kökenli yem maddelerindeki fitik asit; fosfor dışındaki diğer mineral maddeler, nişasta, protein ve proteolitik enzimlerle de kompleks oluşturmaktadır. Kanatlı hayvanların rasyonlarına fitaz enzimi ilave edilerek; fitik asite bağlı fosfor, kalsiyum ve çinko gibi mineral maddeler ile pro-tein, amino asitler ve nişasta sindirilebilirliğinde artış sağlanmaktadır. Rasyona fitaz enzimi ilavesiyle besin maddelerinin sindirilebilirliğinde meydana gelen bu artışlar, kanatlı hayvanların performansında iyileşmeye yol açmaktadır. Ayrıca mineral maddelerin biyoyararlanımlarının artmasıyla gübredeki düzeyleri azalmakta ve böy-lece çevre kirliliğinin önlenmesine katkıda bulunulmaktadır. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Times New Roman'; min-height: 15.0px} p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 10.0px 'Times New Roman'} span.s1 {font: 12.0px 'Times New Roman'}

Significance of Using Phytase Enzyme in Poultry Ration

Poultry rations mostly consist of plant derived feedstuffs as known. Major portion of total phospho-rous in these feedstuffs is form of phytase phosphorous combined with phytic acid which is less available for poultry. Phytic acid in plant derived feedstuffs also creates a complex with other minerals except phosphorus, starch, protein and proteolitic enzymes. Supplementation of phytase enzyme in poultry rations improve the di-gestibility of phosphorous combined with phytic acid, minerals such as calcium and zinc, protein, amino acids and starch. The improvement of nutrient digestibility by supplementation phytase enzyme to the ration increases the performance of poultry. The levels of minerals in the poultry litter decrease by improvement of mineral bioa-vailability which contribute to the prevention of environmental pollution. p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 12.0px 'Times New Roman'; min-height: 15.0px} p.p2 {margin: 0.0px 0.0px 0.0px 0.0px; font: 10.0px 'Times New Roman'} span.s1 {font: 12.0px 'Times New Roman'}
