    Effect of different garlic oil doses on in vitro gas production, rumen fermentation and methane production of sainfoin hay
    (Ankara Univ Press, 2019) Uzatici, Ahmet; Canbolat, Onder
    This study was conducted to determined, effects of addition of garlic oil (GO) 0 (control), 100, 200, 400, 800, 1200 and 1600 mg/L rumen fluid (RF) by in vitro gas production technique, on the true organic matter digestibility (TOMD), organic matter digestibility (OMD), neutral detergent fiber digestibility (NDFD), metabolizable energy (ME) compound and rumen fermentation parameters, carbon dioxide (CO2) and methane (CH4) gas production of the sainfoin (Onobrychis sativa L.) hay. In vitro gas production technique was used to determine the effects of different doses of GO on rumen fermentation, OMD and metabolic energy (ME) level. GKMS and NDFS contents of sainfoin hay were determined by Daisy incubator technique. The addition of GO significantly decreased the in vitro gas production, OMD, NDFD, ME, total volatile fatty acids content (VFA), acetic acid (AA), propionic acid (PA), butyric acid (BA) and the other volatile fatty acids levels of sainfoin hay (P<0.01). In addition, the addition of GO at different doses to the rumen fluid also reduced the production of CH4 and CO2 production (P <0.01). As a result, in vitro gas production, rumen fermentation, nutrient digestion, methane and carbon dioxide production on the most adverse effect garlic oil dose was found to be 1600 mg / L RF. It was concluded that it would be appropriate to use low doses (400 mg / L RF) because of the high GO doses that affect rumen fermentation and the digestion of feed.

    Effect of Sodium Hydroxide Treatment on Chemical Composition and Feed Value of Common Reed (Phragmites australis) Straw
    (Mdpi, 2022) Uzatici, Ahmet; Canbolat, Onder; Kamalak, Adem
    This research was undertaken with the aim of determining the effect of sodium hydroxide (NaOH) treatment on the chemical composition, in vitro gas production, neutral detergent fiber digestibility (NDFD) and true dry matter digestibility (TDMD), dry matter intake (DMI), and relative feed value (RFV) of common reed (Phragmites australis) straw. Reed straw was treated with 0% (control), 1%, 2%, and 3% NaOH and stored in 1.5-L glass jars in triplicate for 21 days. NaOH treatment had a significant effect on the chemical composition, in vitro gas production, NDFD and TDMD, DMI, and RFV of the reed straw. While it decreased the cell wall content of the reed straw, it significantly increased the NDFD, TDMD, DMI, and RFV. The neutral detergent fiber content of the reed straw decreased with NaOH treatment in a dose-dependent manner and ranged from 56.03% to 65.05%, whereas the NDFD increased and ranged from 53.10% to 59.99%. Metabolizable energy, organic matter digestibility, and TDMD values were improved, ranging from 9.15 to 10.19 MJ/kg DM, 58.46% to 65.05%, and 55.29% to 62.33%, respectively. The estimated RFV and DMI also improved, ranging from 84.70% to 95.58% and from 1.87% to 2.14% of body weight, respectively. The most effective treatment dose of NaOH was 3%. Therefore, it can be suggested that NaOH treatment has the potential to improve the nutritive value of reed straw. However, before large applications, further in vivo investigations are required to determine the effects of NaOH treatment on the feed intake and production of ruminant animals.
