Determination of potential nutritive value of young, old and senescent leaves of Arbutus andrachne tree.

Abstract Kamalak, A., Canbolat, O., Atalay, A.I. and Kaplan, M. 2010. Determination of potential nutritive value of young, old and senescent leaves of Arbutus andrachne tree. J. Appl. Anim. Res., 37: 257–260. Potential nutritive value of young, old and senescent leaves of Arbutus andrachne tree was measured using chemical composition and in vitro gas production technique. Maturity had a significantly adverse effect on the chemical composition and in vitro gas production kinetics. Although crude protein (CP), neutral detergent fiber (NDF) and acid detergent fiber contents decreased, condensed tannin (CT) and ash contents increased with maturity. The organic matter digestibility (OMD) and metabolisable energy (ME) ranged from 59.34 to 65.47% and 8.84 to 9.76 MJ/kg DM, respectively. It is concluded that young and old leaves of Arbutus andrachne tree could be considered a moderate quality forage for sheep and goats. However, senescent leaves are only low quality forage.

Bingöl Koşullarında Bazı Burçak [Vicia ervilia (L.) Willd] Genotiplerinin Ot Verimi ve Kalite Özelliklerinin Belirlenmesi

Bu calismada, Bingol ekolojik kosullarinda yetistirilen bazi burcak [ Vicia ervilia (L.) Willd] genotiplerinin ot verimi ve bazi kalite ozelliklerinin belirlenmesi amaclanmistir. Arastirma; Bingol Universitesi, Ziraat Fakultesi, Arastirma ve Uygulama arazisinde 2014-2015 yillarinda yazlik yetistirme sezonunda yurutulmustur. Arastirmada, 14 adet burcak genotipi (IFVE 248-SEL 2785, IFVE 973-SEL 2795, IFVE 2698-SEL 2798, IFVE 2920-SEL 2801 IFVE 3977-SEL 2802, IFVE 3351-SEL 2804, Yerel Lice, D-357, MP, HAT-3, HAT-9, HAT-13, HAT-14 ve HAT-17) bitki materyal olarak kullanilmistir. Calismada tarla denemesi, tesaduf bloklari deneme desenine gore uc tekrarlamali olarak kurulmustur. Arastirmada; bitki boyu, yesil ot verimi, kuru ot verimi, ham kul orani, ham protein orani, ham protein verimi, asit deterjanda cozunmeyen lif (ADF), notral deterjanda cozunmeyen lif (NDF), sindirilebilir kuru madde orani, kuru madde tuketimi ve nispi yem degeri parametreleri incelenmistir. Arastirmada sonucunda, bitki boyu disinda incelenen tum ozellikler bakimindan genotipler arasinda istatistiki olarak p<0.05 ve/veya p<0.01 duzeyinde onemli farkliliklar belirlenmistir. Iki yillik arastirma sonucuna gore, kuru ot ve ham protein verimi ile ADF ve NDF oranlari dikkate alindiginda, IFVE 248-SEL 2785, IFVE 3977-SEL 2802 ve HAT-14 genotiplerinin one ciktigi; adi gecen bu genotiplerin yorede kaba yem uretimine katki saglamasi bakimindan ivedilikle islah calismalarina alinmasi onerilmistir.

CHANGE IN YIELD AND CHEMICAL COMPOSITION OF TALL FESCUE (Festuca arundinacea Schreb.) PLANTS UNDER SALT STRESS

The present study was conducted to investigate the effects of different irrigation water salinity levels (0, 3, 5 and 8 dS/m) on hay yield, chemical composition, gas and methane production, metabolic energy (ME) and organic matter digestibility (OMD) of plants. Experiments were conducted in randomized blocks design with four replications for two years (2014-2015). Calcium chloride (CaCl2), sodium chloride (NaCl) and magnesium sulfate (MgSO4) salts were used to prepare irrigation waters with different salinity levels. Drip irrigation was used. Fresh and dry hay yields, plant height, acid detergent fiber, neutral detergent fiber and crude oil contents decreased with increasing salt doses. Tall fescue Olympus cultivar exhibited a moderate tolerance to salinity. Fresh hay yield decreased by 8.2% at 1.85 dS/m threshold salinity level and dry hay yield decreased 8.2% at 1.97 dS/m threshold salinity level. Crude protein content, gas and methane production, net energy lactation, metabolic energy and organic matter digestibility increased with increasing salt doses. Despite the decreases in hay yield, 8 dS/m did not result in any decreases in protein yields and resulted in low gas and methane production.

GT Biplot Analysis for Silage Potential, Nutritive Value, Gas and Methane Production of Stay-Green Grain Sorghum Shoots

Bu calisma, GT Biplot analizi kullanilarak kalici yesil sorgum genotiplerinin olasi silajini arastirmak icin yurutulmustur . Tahil hasatini takiben, 41 sorgum genotipi silaj yapmak icin dogranmistir. Biyokimyasal analizler, 60 gun silajdan sonra gerceklestirildi. Sonuclar, yesil ot veriminin 13.40-65.96 t ha- 1 arasinda degistigini ortaya koymustur kuru madde oranlari% 24.26-35.83, ham protein orani% 3.44-7.03, ADF oranlari% 27.46-52.01, NDF oranlari% 40.80-69.12, ham kul oranlari% 5.89-15.14, laktik asit icerigi% 1.657-4.914, propionik asit icerigi% 0.000-0.247 arasindadir. Metan uretim degerleri 14.15-21.80%; gaz uretimi 18.51-47.36 mL arasinda, metabolik enerji (ME) 6.68-11.67 MJ / kg DM ve organik madde sindirilebilirligi (OMD) arasinda% 47.20-89.93 arasinda degismektedir. GT biplot analizine gore, asetik, butirik ve propiyonik asitler, pH, kul ve protein icerikleri arasinda metan, ME, OMD ve gaz-metan uretimi arasinda ADF, NDF ve DM arasinda pozitif korelasyonlar vardi; gaz uretimi, ADF ve NDF ile bitki ortusu verimi, ham protein, organik asitler, pH ve ham kul arasinda negatif korelasyonlar vardi. Genotipler arasinda, Sugar grazer, herbisit verimi, G4 ve G3 genotipleri ham protein ile belirgindi. Butun parametreleri goz onune alirsak, genotip G20 ideal genotip gibiydi.
