“…The OM, CP, starch, NDF, and ADF content of the substrate were 92.2, 18.1, 50.8, 12.8, and 4.6% of DM, respectively. Seven concentrations of pure tea saponin were tested (0, 0.04, 0.08, 0.12, 0.15, 0.30, and 0.50 mg/mL), with dosages selected according to previous in vitro experi-ments with tea saponin (Hu et al, 2005a;Guo et al, 2008;Arhab et al, 2014). Within each incubation, every treatment was assayed in duplicate.…”

The effect of tea saponin supplementation in the ruminant diet on methane emissions, rumen fermentation, and digestive processes is still under debate. The objective of this study was to assess the effect of this plant extract on methanogenesis, total-tract digestibility, and lactating performances of dairy cows. The work included 2 independent and successive experiments. First, the effect of 7 tea saponin doses (from 0 to 0.50 g/L) on methane emissions and protozoa concentrations was tested in 2 repeated in vitro batch culture incubations using bovine rumen contents as inoculum and a cereal mixture as substrate. After 18 h of incubation, total gas production and composition as well as rumen fermentation parameters and protozoa concentration were analyzed. Increasing dosage of the plant extract reduced methane production and protozoa concentration, with a maximum reduction of 29% for CH (mL/g of substrate) and 51% for protozoa (10/mL). Tea saponin did not affect volatile fatty acids concentration, but marginally decreased total gas production by 5% at the highest dose. Second, a 2-period crossover design experiment was carried out with 8 lactating dairy cows fed a basal diet (54% corn silage, 6% hay, and 40% pelleted concentrates on a dry matter basis) without (control) or with 0.52% tea saponin (TSP). Each experimental period lasted 5 wk. Animals were fed ad libitum during the first 3 wk of the period (wk 1, 2, and 3) and restricted (95% of ad libitum intake) during the last 2 wk (wk 4 and 5). Intake and milk production were recorded daily. Methane emissions were quantified using open chambers (2 d, wk 4). Total-tract digestibility and nitrogen balance were determined from total feces and urine collected separately (5 d, wk 5). Rumen fermentation parameters and protozoa concentration were analyzed from samples taken after morning feeding (1 d, wk 5). Milk production, dry matter intake, and feed efficiency were reduced with TSP (-18, -12, and -8%, respectively). As daily methane production (g/d) was not affected, methane emissions (g/kg of dry matter intake) increased by 14% with TSP. Total-tract digestibility and nitrogen balance were similar between diets, except for acid detergent fiber digestibility, which tended to be improved with TSP (+4 percentage units). Rumen fermentation parameters and protozoa concentration were relatively unchanged by diets. Under the conditions of this experiment, tea saponin is not efficient to reduce methane emissions from dairy cows.

Bu çalışma Van YYÜ Ziraat Fakültesi deneme arazisinde 1 Nisan ve 20 Nisanda ekimi yapılan çemen bitkisinden elde edilen kuru otlar üzerinde gerçekleştirilmiştir. Ekimler sırasında, nodozide bakteri inokulantı ve Diamonyumfosfat (DAP), Kentsel arıtma çamuru (KAÇ), Humik Asit (HA), Çiftlik gübreleri (ÇG) uygulanmıştır. Çalışmada Gürarsan çeşidi çemen (Trigonella foenum graecum L.) bitkisinin kuru otlarının besin maddesi içeriklerinin ve in vitro sindirim değerlerini belirlemek amaçlanmıştır. Elde edilen çemen otlarının kuru madde (KM), ham kül (HK), organik madde (OM), ham protein (HP), nötral deterjan fiber (NDF), asit deterjan fiber (ADF) değerleri ve in vitro KM, HK ve OM sindirimleri tespit edilmiştir. Çalışma sonunda edilen bulgular değerlendirildiğinde, 20 Nisanda, bakteri uygulaması yapılarak, Humik asit içeren gübre kullanılması hayvan besleme açısından besin madde içerikleri görece daha iyi olan çemen otlarının elde edilebileceği söylenebilir. İn vitro sindirim değerleri dikkate alındığında ise 1 Nisanda ekimi yapılan çemen bitkisine bakteri uygulaması ve DAP gübresi kullanılmasının daha iyi olacağı kanaati oluşmuştur.

Macrotyloma uniflorum (kulthi) seeds, Asparagus racemosus (shatavari) roots or Acacia concina (shikakai) pods were supplemented to total mixed rations (TMR) @ 0-3% (on DM basis) to assess the impact of herbal feed additives (HFAs) on the in vitro rumen fermentation pattern. The saponin content and 2, 2-diphenyl-1-picrylhydrazyl- hydrate (DPHH) antioxidant activity was highest in A. racemosus than other HFAs. But total phenols, non tannin phenols, true tannins, condensed tannins, vitamin C and flavanoid contents were highest inM. uniflorum and lowest in A. concina. The dose/level of supplementation of HFAs, irrespective of their nature did not affect net gas production (NGP) and availability of metabolizable energy (ME) from TMR, but digestibility of nutrients and partitioning factor (PF) decreased in comparison to the unsupplemented group. The total and individual volatile fatty acids (VFAs) production; and acetate to propionate ratio was improved when the TMR was supplemented with HFAs at 1% level. The methane and ammonia-N production was depressed at 2% level as compared to control group. Irrespective of the dose, the total VFAs, acetate, and propionate production was higher while ammonia-N decreased in M. uniflorum supplemented TMR than other HFAs supplemented groups. Methane production from the TMR was comparable in the diet supplemented with different HFAs, however, diet supplemented with M. uniflorum resulted in lower methane production. Amongst the tested HFAs, M. uniflorum was a richer source of most of the bio-active compounds. Based on in vitro fermentation parameters, M. uniflorum supplemented to TMR @ 2% gave the best results.
