“…Inclusion of hemp stems in an oaten chuff diet in sheep increased apparent digestibility of OM, CP, NDF and ADF and acetate and butyrate concentrations in the rumen [36], underlining the ability of the rumen microorganisms to degrade hemp straw effectively despite its high fiber content. For flax straw an organic matter digestibility of 33.9% was reported in an in vitro assay [37], while lambs were able to digest 49% of flax straw organic matter [38]. In a comparison of barley straw, canola straw, timothy and alfalfa hay, in situ NDF and ADF digestibility of canola straw reached about 27% after 48 h which was considerably lower than for the other substrates [39].…”

To mitigate greenhouse gas emissions and improve energy supply security, there is an increasing effort toward the use of non-fossil energy sources. Crop residues have a great potential to be exploited as biomass for biogas production. However, due to their lignocellulosic structures they are difficult to degrade and do not reach competitive performance. A feasible option to mine these substrates is present in the forestomach of ruminants. Therefore, the aim of the present study was to use rumen microorganisms to improve anaerobic digestion (AD) of crop residues. For this purpose, hemp straw, mechanically pre-treated hemp fibers and shives, flax straw, flax shives, and aged and fresh rapeseed straw were evaluated using the rumen simulation technique. The AD of the substrates was divided into three batches. In two batches, hay was added as a control substrate. In summary, none of the analyzed substrates had an equivalent performance as the control hay, but pre-treated hemp fibers and shives had better AD parameters compared to all other alternative substrates, with the lowest pH (mean: 6.81), highest short chain fatty acid (20.0 mmol/day) and H2 production (25.6 mM) and highest degradability (25.2%). Flax straw had the second-best performance (6.81, 17.4 mmol/day, 20.6 mM and 22.2%, respectively), followed by fresh rapeseed straw, hemp straw, aged rapeseed straw and flax shives. Therefore, hemp fibers and shives demonstrated to be the most suitable substrates for AD. However, since pre-treatment can represent significant additional costs for biogas production, flax straw also demonstrated to be a good alternative.

“…Nowadays, flax straw appeared in the surface as its abundant by-products of oil seed flax industry and available in a large quantity (31,000 tons/year in Egypt, ARC, 2004).In the same time, few trails were conducted to enhance the availability of flax straw for ruminants feeding by treatments such as ammoniation and supplemented with barley grain for beef cattle (Mann et al, 1988). Also, it was tried to fed ammoniated flax straw with sweet clover hay for sheep (Howard et al, 1991). Many studies have been done to enhance the utilization of crop residues of cereal and legumes using pre-treatment methods.…”

Six male adult Barki sheep (42kg± 1.5kg), three each group were used for digestibility trails. Four lactating cows were arranged in 4x4 Latin square to carry out the lactation experiment. Animals were fed experimental diets containing 1. Flax straw without (FS). 2. Flax straw treated with urea at 4% on DM basis, (UFS). 3. Flax straw treated with Trichodema viride (FFS). 4. Flax straw treated with urea and Trichodema viride (UFFS). The results explained that, FS treatment had significant effect on digestibilities of DM (P < 0.0003), OM (P< 0.0001), CF and CP (P < 0.0004), and EE (P < 0.036), while no significant effect was detected for NFE. Sheep fed diet containing UFFS showed higher (P < 0.0001) digestibility of NDF and cellulose followed by those fed FFS containing diet without significant differences .But they had higher (P < 0.0001) digestibility of ADL and hemicellulose compared to other diets. While, those fed FFS containing diet, had the highest (p < 0.0001) digestibility of ADF (39.76 %). Treatments of flax straw had no significant effect on dry matter intake (DMI). But, it had significant effect (P < 0.0001) on NB and biological value of N (NB/AN). Diet of UFFS was more effective for increasing N-utilization of experimental diets and feeding value expressed as TDN (P < 0.0001) and DCP (P < 0.0007). Diet of UFFS increased milk yield and yields of milk fat, milk protein and 4 % (FCM) yields. No significant influences were observed for milk lactose, SNF, TP, and ash while increased (P < 0.0018) milk TS and fat (%). Treatments of FS had no harmful effects on blood patterns. UFFS diet showed the best economic feed efficiency followed by FFS, FS and UFS diets. It can be concluded from this study that, treatments with urea followed by fungus (T. viride) treatment could be promising for utilization straw for sheep and dairy cows.

caeruleus (L.) Desr.)'nın Farklı Gelişme Dönemlerindeki Yem Verimi ve Kalitesinin Belirlenmesi* Determination of Forage Yield and Quality of Blue Melilot (Melilotus caeruleus (L.) Desr.) at Different Growth Stages under Edirne Ecological Conditions *Bu makale, yüksek lisans tezinden özetlenmiştir. ÖZAmaç: Bu çalışma, farklı gelişme dönemlerinin mavi taş yoncasının ot verimi ve kalitesine etkisinin belirlenmesi amacıyla yapılmıştır. Materyal ve Metot:Edirne ili Hasanağa köyü çiftçi koşullarında 2016-2018 yılları arasında 2 yıl süreyle Tesadüf Blokları Deneme Desenine göre 3 tekrarlamalı olarak yürütülen araştırmada, Tekirdağ Namık Kemal Üniversitesi Ziraat Fakültesi Tarla Bitkileri Bölümü tarafından geliştirilen BG-3 mavi taş yoncası hattı materyal olarak kullanılmıştır. Ekim normu 3 kg/da olacak şekilde sıra arası 20 cm olan ve 5 m uzunlukta 8 sıradan oluşan parsellere sonbaharda kışlık ekim (birinci yıl 21.10.2016 tarihinde, ikinci yıl 25.10.2017 tarihinde) yapılmıştır. Tomurcuklanma başlangıcı, % 50 çiçeklenme ve meyve bağlama dönemlerinde morfolojik gözlemler (bitki boyu, bitkide yaprak sayısı, yaprak uzunluğu, yaprakçık boyu ve eni ile yaprak/sap oranı) yapılarak yeşil ve kuru ot verimleri ile bazı kalite özellikleri (ham protein oranı, asit deterjanda çözünmeyen lif ve nötr deterjanda çözünmeyen lif ) belirlenmiştir.Bulgular: Farklı gelişme dönemlerinin bitki boyu, bitkide yaprak sayısı, yaprak/sap oranı, yeşil ot verimi, kuru ot verimi, ham protein oranı, asit deterjanda çözünmeyen lif ve nötr deterjanda çözünmeyen lif oranlarını etkilediği, yaprak uzunluğu, yaprakçık eni ve boyuna ise etkili olmadığı tespit edilmiştir.Sonuç: Mavi taş yoncasının farklı büyüme dönemlerinde yapılacak biçimle elde edilen yeşil ve kuru ot verimleri ile otun kalitesinde farklılıklar olduğu, yüksek ot verimi için meyve bağlama döneminde biçilebileceği belirlenmiştir.
