Yonca kuru otu ve çayır kuru otunun hücre duvarı unsurlarının rumende parçalanabilirlikleri ve parçalanma özellikleri

Bu araştırmada yonca kuru otu (YKO) ile çayır kuru otu (ÇKO) hücre duvarı unsurlarının rumende parçalanabilirlikleri ve parçalanma özellikleri karşılaştırılmıştır. Bu amaçla, 70 kg canlı ağırlığındaki rumen kaniillü 3 baş Akkaraman koç kullanılmıştır. Deneme yemleri 8, 16, 24, 48, 72 ve 96 saatlerde rumende inkübasyona maruz bırakılmıştır. Araştırma sonucunda, nötr deterjanda çözünmeyen lif (NDF) ve asit deterjanda çözünmeyen lif (ADF) için rumende çözünebilir kısım (a) (P

Degradability and degradation characteristics of cell wall components of alfalfa hay and grass hay in rumen

In this research was to compare degradability and degradation characteristics of cell wall components of alfalfa hay (AH) and grass hay (GH) in rumen. For this purpose, 3 Akkaraman rams were used, which were 70 kg live weight and rumen cannulated. The experimental feeds were incubated in the rumen for 8, 16, 24, 48, 72 and 96 hours. At the end of the research, it was found that the differences between the two feeds are important (P< 0.05) for neutral detergent fiber (NDF) and acid detergent fiber (ADF), according to the solüable part in the rumen (a) (P< 0.01), the degradable part in various time intervals (b), the rate constant of degradation of b (c), maximum degradability (a+b) and effective degradability (ED) (k=2) (P< 0.05). It was also found out that for level k=5, the differences.between the feeds according to effective degradability are not important (P>0.05). It was observed that the acid detergent lignin (ADL) didn't degredate until 72 hours. As a result, the two forages were found to be different according to NDF and ADF degradability and degradation characteristics (GH>AH) and it was also observed that degradability and degradation characteristics are affected by the cell wall components.
