Bazı Sebze Yaprakların Kimyasal Kompozisyonları ve Ruminant Hayvanlar için Besleme Değerinin Belirlenmesi

Bu çalışma bazı sebze yapraklarının kimyasal kompozisyonunu ve ruminantlar için besleme değerinibelirlemek için yürütülmüştür. Sebzenin türü yaprakların kimyasal kompozisyonunu önemli (P<0.001) derecedeetkilemiştir. Sebzelerin kuru madde, ham kül, ham protein, nötral deterjan fber, asit deterjan fber içeriklerisırasıyla %8.29 ile 20.89, %17.78 ile 26.36, %13.55 ile 22.51, %24.84 ile 35.72 ve %16.18 ile 25.93 arasındadeğişmiştir. Kırmızı ve beyaz turp yaprağının ham protein içeri diğer sebzelerin ham protein içeriğinden önemliderecede (P<0.001) daha yüksek bulunmuştur. Şeker pancarı yaprağının nötral deterjan fber içeriği diğer sebzelerinnötral deterjan fber içeriğinden önemli derecede (P<0.001) daha yüksek bulunmuştur. Sebze türü sebzelerin gazüretimini, metabolik enerji ve metan üretimini önemli derecede (P<0.001) etkilerken sebzelerin organik maddesindirim derecesini önemli derecede (P>0.05) etkilememiştir. Sebzelerin gaz üretimi 37.93 ile 45.25 ml arasındadeğişmiştir. Siyah havuç ve kereviz yaprağından üretilen gaz miktarı diğer sebzelerden önemli derecede (P<0.001)daha yüksek bulunmuştur. Sebzelerin metabolik enerji içeriği 8.90 ile 10.16 MJ/kg arasında değişmiştir. Sebzelerinmetan üretimi 6.67 ml ile 11.13 ml arasında değişmiştir. Şeker pancarı yaprağının metan üretimi diğer sebzelerinmetan üretiminden daha yüksek bulunmuştur. Metan gazı üretiminin yüzdesel olarak 17.60 ile 25.46 arasındadeğişmiştir. Siyah havuç, beyaz havuç, kırmızı turp, beyaz turp, kereviz ve şeker pancarı yaprağı ruminanthayvanlara enerji ve protein sağlamada önemli bir potansiyele sahiptir. Bununla birlikte şeker pancarının ruminanthayvanların rasyonlarına katılması durumunda şeker pancarının yüksek miktarda metan üretim potansiyeli gözönüne alınmalıdır.

Determination of Chemical Composition and Nutritive Value of Some Vegetables Leaves for Ruminant Animals

The current experiment was carried out to determine the chemical composition and nutritive valueof leaves of some vegetables for ruminant animals. The species signifcantly (P<0.001) affected the chemicalcomposition of vegetable leaves. The dry matter (DM), crude ash (CA) crude protein (CP), neutral detergent fber(NDF) and acid detergent fber (ADF) of vegetables leaves varied between 8.29 and 20.89%, 17.78 and 26.36%,13.55 and 22.51%, 24.84 and 35.72%, and 16.18 and 25.93% respectively. The CP contents of leaves from Raphinusradicula and Raphinus sativus were signifcantly (P<0.001) higher than the other vegetables. The NDF content ofleaves from Beta vulgaris was signifcantly (P<0.001) higher than the others. The ADF content of Raphinus sativuswas signifcantly (P<0.001) higher than the others. The species signifcantly (P<0.001) affected the gas production,metabolisable energy and methane production although OMD of vegetable leaves was not signifcantly (P>0.05)affected by species. The gas production of vegetable leaves varied between 37.93 and 45.25 ml. The gas productionof Daucus carota var atrorubens and Apium graveolens were signifcantly (P<0.001) higher than the others. Themetabolisable energy ranged from 8.90 to 10.16 MJ/kg DM. The methane production (ml) varied between 6.67ml to 11.13 ml. The methane production of Beta vulgaris was signifcantly (P<0.001) higher than the others. Thepercentage of methane production ranged from 17.60 to 25.46%. Leaves of vegetables from Daucus carota varatrorubens, Daucus carota, Raphinus radicula, Raphinus sativus, Apium graveolens and Beta vulgaris have asignifcant potential to provide considerable amount of energy and protein for ruminant animals. However highlevel of methane production potential of leaves of Beta vulgaris should be taken into consideration when includedinto ruminant diets
