Nutrient and botanical composition of pasture in Ceylanpınar Agriculture Farm

Bu çalısma, Ceylanpınar Tarım İsletmesi merasının, degisik vejetasyon dönemlerinde (1 Nisan -1 Haziran), kalitesini belirlemek amacıyla yapılmıstır. İki haftada bir toplanan ot örneklerinde bitki boyu, kuru madde verimi, besin madde [kuru madde (KM), ham protein (HP), ham yag (HY), ham kül (HK), neutral detergent fiber (NDF), acid detergent fiber (ADF) ve organik madde (OM)] ve enerji içerikleri belirlenmistir. Çalısmada ayrıca, meranın organik madde sindirilebilirligi (OMS) ile birim alandan elde edilen sindirilebilir organik madde (SOM) ve enerji miktarları da hesaplanmıstır. Vejetasyonun ilerlemesine baglı olarak mera otlarında KM, NDF ve ADF düzeyleri artarken (P< 0.05); HP ve HY düzeyi ile OMS ve enerji düzeyleri azalmıstır (P< 0.05). Meranın kuru ot veriminin, örneklenmenin 3. ve 4. döneminde en üst düzeyde olması, SOM ve enerji verimlerini 3. dönemde maksimum düzeye yükseltmistir. 1., 2., 3., 4 ve 5. örnekleme dönemlerinde meranın kuru ot verimi sırasıyla 32,96, 48,62, 66,51, 59,04 ve 40,71 kg/dekar; ham protein düzeyi %14.88, %14.08, %11.99, %9.19 ve %7.18; OMS sırasıyla %67.09, %62.24, %60.35, %58.96 ve %55.95; ME degerleri sırasıyla 10.15, 9.42, 9.13, 8.92 ve 8.46 MJ/ kg KM; NEL degerleri ise aynı sıraya göre 6.38, 5.88, 5.68, 5.54 ve 5.23 MJ/ kg KM olarak belirlenmistir. Bu çalısmada, Ceylanpınar Tarım İsletmesi merasının, iklim sartlarının da etkisiyle, mayıs ayının ikinci yarısından itibaren hızla kartlasmaya ve kurumaya basladıgı ve dolayısıyla besin maddeleri ve enerji bakımından fakirlestigi; özellikle bu dönemden sonra merada otlayan hayvanlara ek yemleme yapılmasının zorunlu oldugu sonucuna varılmıstır.

Ceylanpınar tarım işletmesi merasının besin ve botaniksel kompozisyonu

This study was performed to determine the pasture quality at different vegetation periods (1 April-1 June) in Ceylanpınar Agricultural Farm. Plant length, dry matter yields and nutrient matter [dry matter (DM), crude protein (CP), ether extract (EE), ash, neutral detergent fiber (NDF), acid detergent fiber (ADF), organic matter (OM)] and energy contents were determined at plant samples collected once every two weeks. In this research, organic matter digestibility of pasture (OMD), and digestible organic matter (DOM) and amount of energy obtained per area unit has also been calculated. CP, EE, OMD and energy levels decreased (P<0.05), whereas DM, NDF and ADF levels increased (P < 0.05), in pasture hay because of advancing maturity. The highest level of hay yield in the pasture at third and fourth period of sampling increased DOM and energy yield of pasture to the maximum level at the third period. Dry matter yields, crude protein, OMD, ME and NEL of pasture in sampling periods of 1st, 2nd, 3rd, 4th and 5th were found as 32.96, 48.62, 66.51, 59.04 and 40.71 kg/decare; 14.88% , 14.08 %, 11.99 %, 9.19 % and 7.18 % ; 67.09 %, 62.24 %, 60.35 %, 58.96 % and 55.95 %; 10.15, 9.42, 9.13, 8.92 and 8.46 MJ/ kg DM; 6.38, 5.88, 5.68, 5.54 and 5.23 MJ/ kg DM, respectively. In conclusion, Ceylanpınar Agricultural Farm Pasture begin to grow old and dry after second period of May because of climate conditions and become insufficiency of nutrients and energy. For this reason, food supplementation is inevitable to grazing animals at the pasture, especially following this period.
