Bu çalışmanın amacı, farklı hasat zamanının pamuk dikeninin (Onopordum acanthium) kimyasal kompozisyon, in vitro gaz üretimi, metan üretimi, metabolik enerji (ME) ve organik madde sindirim derecesi (OMSD) üzerine etkisini belirlemek için yapılmıştır. Hasat zamanı pamuk dikeninin kimyasal kompozisyonunu, in vitro gaz üretimi, metan üretimi, ME, OMSD’i önemli derecede etkilemiştir (P<0.01). Hasat zamanının ilerlemesiyle birlikte pamuk dikeninin kuru madde (KM), ham yağ (HY), nötral deterjan fiber (NDF), asit deterjan fiber (ADF) ve metan (%) içeriği artarken, ham kül (HK), ham protein (HP), in vitro gaz üretimi (ml), metan üretimi (ml), OMSD ve ME değerleri ise azalmıştır. Pamuk dikeninin KM, HP, HY, NDF ve ADF içerikleri sırasıyla %16.22 ile 33.03, %8.72 ile 15.09, %2.68 ile 4.37, %38.25 ile 60.13 ve %27.08 ile 42.91 arasında değişmiştir. Pamuk dikenin in vitro gaz üretimi (mL), metan üretimi (mL), metan gazı (%), OMSD ve ME sırasıyla 32.84 ile 48.49 mL 4.83 ile 5.94 mL, %12.25 ile 14.73, %49.71 ile 63.18 ve 7.46 ile 9.97 MJ/kg KM arasında değişmiştir. Bundan sonra pamuk dikenin ruminant hayvanların yem tüketimine ve performansına etkisine belirlenmek için in vivo çalışmalara ihtiyaç vardır.
The aim of this study is to determine the effects of different harvest times on the chemical composition of cotton pine (Onopordum acanthium), in vitro gas production, methane production, metabolic energy (ME) and organic substance digestive degree (OMSD). The time of harvest has significantly affected the chemical composition of cotton pipe, in vitro gas production, methane production, ME, OMSD (P<0.01). With the progress of the harvest time, the content of cotton cotton dry material (KM), raw oil (HY), neutral detergent fiber (NDF), acid detergent fiber (ADF) and methane (%) has increased, while the raw ashes (HK), raw protein (HP), in vitro gas production (ml), methane production (ml), OMSD and ME values have decreased. The content of cotton pipe is KM, HP, HY, NDF and ADF respectively; 16.22 to 33.03, 8.72 to 15.09, 2.68 to 4.37, 38. It varied from 25 to 60.13 and 27.08 to 42.91. The in vitro gas production (mL), methane production (mL), methane gas (%), OMSD and ME varied from 32.84 to 48.49 mL respectively; 4.83 to 5.94 mL, 12.25 to 14.73, 49.71 to 63.18 and 7.46 to 9.97 MJ/kg KM respectively. After that, in vivo studies are needed to determine the impact of cotton pine on feed consumption and performance of ruminant animals.
The aim of the current experiment was carried out to determine the effect of different harvesting time on the chemical composition, in vitro gas production, methane production, metabolisable energy, organic matter digestibility of cotton thistle. The harvesting time had a significant effect on the chemical composition, gas production, methane production, organic matter digestibility and metabolisable energy of cotton thistle (P<0.01). The dry matter, ether extract, neutral detergent fiber, acid detergent fiber and methane production (%) increased with advancing maturity whereas crude ash, crude protein, gas production (ml), methane production (ml), organic matter digestibility and metabolisable energy decreased with advancing maturity. Dry matter, crude protein, ether extract, neutral detergent fiber, acid detergent fiber contents of cotton thistle ranged from 16.22 to 33.03%, 8.72 to 15.09%, 2.68 to 4.37%, 38.25 to 60.13% and 27.08 to 42.91% respectively. Gas production (mL), methane production (mL), methane production (%), organic matter digestibility and metabolisable energy of cotton thistle ranged from 32.84 to 48.49 ml, 4.83 to 5.94 mL, 12.25 to 14.73%, 49.71 to 63.18% and 7.46 to 9.97 MJ/kg DM. Further in vivo studies are required to determine the effect of cotton thistle on the feed intake and performance of ruminant animals.
