Determination of microbial gas production, fermentation kinetics and digestibility of alternative crop silages

Öz:

Yedi farklı bitki familyasından yapılmış silajların (arpa, üçgül, çim, kolza, gazal boynuzu, kaba yonca, korunga) ve bunlara ait 10 farklı yemin, tercih edilmeyen kısmının (refusal) kuru madde kaybına dayalı sindirilebilirligi, fermentaston kinetiği ve mikrobiyal gaz üretimi belirlenmiştir. Mikrobiyal gaz üretimi taze ve öğütülmüş silajlar ve artık yem örnekleri kullanılarak 120 saatlik inkübasyonun belirli dönemlerinde basınç ölçme tekniği (PTT) ile tayin edilmiştir. Taze ve öğütülmüş silajların mikrobiyal gaz üretimi birbirine benzer bulunmuştur (r2 = 0,90). Öğütülmüş ve taze silajlarda kolza en fazla mikrobiyal gaz üretimine neden olurken tercih edilmeyen yemler için en fazla mikrobiyal gaz üretimi çim silajında gerçekleşmiştir. Farklı silajlara ait lag süreleri arasında bir farklılık gözlenmemiş fakat gaz üretiminin % 50 ve % 95'e ulaşma zamanı öğütülmüş silajlarda taze ve tercih edilmeyen kısm silajlara oranla daha kısa bulunmuştur. Toplam uçucu yağ asitlerinin üretimi artık yemlerde taze ve öğütülmüş silajlara oranla daha az gerçekleşmiş fakat taze ve öğütülmüş silajlar arasında uçucu yağ asitleri üretimi bakımından farklılık gözlenmemiştir. Kuru madde (KM) kaybı öğütülmüş ve taze silajlarda benzerlik göstermesine rağmen artık yemlerdeki KM kaybı daha az düzeyde gerçekleşmiştir. Bu sonuçlar tercih edilmeyen yemin hayvanlar tarafından kullanılabilecek değerli ve sindirilebilir bir yem kaynağı olduğunu göstermiştir.

Microbial gas production (MGP), fermentation kinetics and DM loss of crop silages made from 7 different plant families (barley/pea, clover, grass, kale, lotus, lucerne, sainfoin) and 10 different refusals were determined. The pressure transducer technique (PTT) was used to measure the microbial gas production of fresh and ground silages and refusal samples at regular intervals throughout the 120 h incubation. The MGP of fresh and ground silages were similar (r2 = 0.90). The maximum gas production was obtained from kale for ground and fresh silages whilst grass silage yielded the maximum gas pool for refusals. No differences were found between lag time but times to produce 50% and 95% gas pool were shorter with ground silages than with fresh silages and refusals. Total volatile fatty acid (VFA) production was notably lower for refusals compared to fresh and ground silages, yet ground and fresh silages yielded similar VFA levels. Dry matter (DM) losses of ground and fresh silages were similar. However, lower DM losses were observed for refusals. These results suggest that refusals could be used as a valuable and digestible feed-stuff for animals.
