Determination of Changes Occurring Annual Nutritional Contents of Gum Tragacanth (Astragalus gummifer L.)

Öz

This research was conducted to determine the changes of annual nutritional content gum tragacanth
(Astragallus gummifer L.) grown in Igdir ecological conditions. In this research, Stem + leaf samples were collected
during 7 (seven) month between April and October that plant isn’t dormant in 2015 year. Changes as months of
CP (Crude protein), NDF (Neutral Detergent Fiber), ADF (Acid Detergent Fiber) ADL (Acid Detergent Lignin),
DMD (Dry matter digestibility), DE (Digestible energy), ME (Metabolizable energy), DMI (Dry matter intake),
RFV (Relative feed value) and DM (Dry matter ratio) contents of gum tragacanth were determined. According
to this results, the highest CP, DMD, DE, ME, DMI and RFV rates in April (16.04%, 58.63%, 2.77 Mcal g-1, 2.28
Mcal g-1, 2.29%, 104.19, respectively), and also the lowest rates in October (3.82%, 43.83%, 2.14 Mcal g-1, 1.76
Mcal g-1, 1.66%, 55.04 respectively) was determined. However, the highest NDF, ADF and ADL rates in October,
(74.47%, 57.84% and 9.96%, respectively) the lowest value in April (52.45%, , 38.85%, 6.02%, respectively) were
determined.

Sakız Geveni (Astragallus gummifer L.)’nin Yıllık Besin İçeriğinde Meydana Gelen Değişimlerin Belirlenmesi

Öz

Bu araştırma, Iğdır ekolojik koşullarında yetişen Sakız Geveni (Astragallus gummifer L.) çalısının yıllık
besin içeriği değişimini belirlemek için yürütülmüştür. Bu amaçla bitkinin dormant olmadığı Nisan ile Ekim
ayları arasında olmak üzere 7 (yedi) ay süresince sap + yaprak örnekleri alınmış ve yem örneklerinin HP (ham
protein), NDF (neutral detergent fbre), ADF (acid detergent fbre), ADL (acid detergent lignin), KMS (kuru madde
sindirilebilirliği), SE (sindirilebilir enerji), ME (metabolik enerji), KMT (kuru madde sindirilebilirliği), NYD
(nispi yem değeri) ve KOO (kuru ot oranı) içerikleri aylar göre değişimleri saptanmıştır. Yapılan çalışmada bitkide
gelişme döneminin ilerlemesiyle birlikte HP, KMS, SE, ME, KMT, NYD oranları azalmış, NDF, ADF ve ADL
miktarları ise artmıştır. Bu sonuçlara göre HP, KMS, SE, ME, KMT, NYD oranları en yüksek gelişme döneminin
başlangıcı olan Nisan ayında (sırasıyla % 16.04, % 58.63, 2.77 Mcal g-1, 2.28 Mcal g-1, % 2.29, 104.19), en düşük
ise Ekim ayında (sırasıyla % 3.82, % 43.83, 2.14 Mcal g-1, 1.76 Mcal g-1, % 1.66, 55.04) belirlenmiştir. NDF, ADF
ve ADL oranları ise en yüksek gelişme döneminin sonu olan Ekim ayında (sırasıyla % 74.47, % 57.84 ve % 9.96),
en düşük değerlerde Nisan ayında (sırasıyla % 52.45, % 38.85, % 6.02) belirlenmiştir.
