Determination of the feed values of Çaşir (Prangos ferulacea) and goat’s thorn (Astragalus gummifera) located in natural plant flora of the Southeastern Anatolia region

Bu çalışmada in vitro gaz üretim tekniği kullanılarak ve kimyasal içeriğine gore Türkiye’deki bazı alternatif yem kaynaklarının besin değerlerinin incelenmesi amaçlanmıştır. Çalışmada Çaşir (Prangos ferulacea) ve keçi dikeni (Astragalus gummifera) bitkilerinin yaprak, dal ve ana gövde kısımları kullanılmıştır. Elde edilen değerler yonca otu (Medicago sativa) ile kıyaslanmıştır. Yonca kuru otunun (YKO) protein değeri Prangos ferulacea yaprak (P1), dal (P2) ve gövde (P3) ile Astragalus gummifera yaprak (A1), dal (A2) ve gövde (A3) kısımlarından daha yüksek olmuştur (P

The aim of this study was to determine the nutritive value of some alternative forage in Turkey by using chemical composition and in vitro gas production kinetics. In this study, casir (Prangos ferulacea) leaves, branch, corpus and goat’s thorn (Astragalus gummifera) spines, branch and corpus were used. The values of these forages were compared with alfalfa hay (AH=Medicago sativa). The crude protein content of AH was significantly higher than those of P. ferulacea leaves (P1), P. ferulacea branch (P2), P. ferulacea corpus (P3), A. gummifera spines (A1), A. gummifera branch (A2), A. gummifera corpus (A3) (P<0.01). The neutral detergent fiber (NDF) content of P. ferulacea leaves was significantly higher than those of other forages (P2, P3, A1, A2, A3) (P<0.01). There were significant differences among P. ferulacea, A. gummifera and AH in terms of in vitro gas production kinetics as well as estimated parameters such as metabolizable energy (ME), net energy lactation (NEL) and organic matter digestibility (OMD). ME, NEL and OMD values of Prangos leaves were significantly higher than those of AH. The RFV of AH were significantly higher than those of P1, P2, P3 and A1, A2, A3 (P<0.001). Current results show that the feed value of P. ferulacea is higher compared to A. gummifera but lower than feed value of alfalfa hay.
