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

Abstract

ÖZET: 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 fibre), ADF (acid detergent fibre), 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. ABSTARCT: 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

Determination of In Vitro True Digestibility and Relative Feed Values of Alternative Roughage Sources

“…In this study, it was determined that the dry matter contents of F hay, G hay, and O leaves are higher than A and H hay. As it is known, trees and shrubs have higher DM and fiber concentrations and lower CP concentrations in summer than herbs (Demir and Keskin, 2016;Dökülgen and Temel, 2020). In this study, the CP content of hays ranged from 7.35 to 19.28%.…”

Bazı Dormansi Kırma Uygulamalarının ve Sıcaklığın Sakız Geveni’nin (Astragalus gummifer Labill.) Tohum Canlılığı Üzerine Etkileri

“…Astragalus species are spread over a wide area such as Europe, Asia, and North America, with 463 species and 41% (210 species) of these species endemic in Turkey (Dinç et al, 2013;Erkul and Aytaç, 2013). Astragalus species are widely used as a feed source for animals, as a raw material for medicine, dye, textile industry, as a source of nectar for bees, and also in the control of erosion areas (Demir and Keskin, 2016;Keskin and Temel, 2019;Bagheri et al, 2015;Budge et al, 2012;Lee et al, 2007;Abd Kadir et al, 2013). Astragalus brachycalyx, Astragalus gummifer, Astragalus kurdicus, and Astragalus microcephalus species from which gum called tragacanth is extracted are widely found in Turkey, Iran, Caucasus, and Afghanistan regions, and this gum obtained is used in pharmacy, paint and weaving industries (Khan and Abourashed, 2010).…”
