This study was conducted in Grand station of Diwania/ Taj Al-Nahrain company- Al-Qadisiya Province for 84 days to investigate the effect of level of addition of commercial baker's yeast Saccharomyces cerevisiae,0, 15 and 30 g/cow/day to concentrate diet on rumen fermentation characteristics  in German Holstein Friesian lactating cows.  Nine multiparous Holstein cows in their mid-lactation were used. Daily feeding program applied in that station included offering 1 kg of concentrate diet per 3-4 kg milk produced divided into morning and evening meals, 10 kg of green forage, 10 kg whole plant corn silage and free choice of rice straw. Silage was characterized with accepted quality and fermentation parameters, values of pH, concentrations of ammonia nitrogen (NH3-N) and total volatile fatty acids (TVFA) were, 3.5, 0.98% of total nitrogen and 2.55 mM/DM respectively. Results revealed that addition of yeast at level of 15 and 30 g/cow/day reduced (P<0.01) concentration of NH3-N from 18.14 to 13.92 and 14.21 mg/100 ml respectively. Significant (P<0.01) increase in concentration of TVFA from 7.32 to 9.39 mM /100 ml was also observed due to addition of yeast at level of 15 g/cow/day. However, ruminal pH values were not affected by addition of yeast

The objective of this study was to evaluate short-term variations of trans fatty acids (TFA) in plasma lipoproteins and ruminal fermentation parameters of non-lactating cows subjected to ruminal pulses of vegetable oils. Three non-lactating, non-pregnant Holstein cows, each with a ruminal cannula, were arranged in a 3 × 3 Latin square design with three-day pulsing periods and four-day washout intervals between treatments. Cows were treated with single ruminal pulses of: (1) control (skimmed milk (SM); 500 mL); (2) soybean oil (SO; 250 g/d in 500 mL of SM) and (3) partially-hydrogenated vegetable oil (PHVO; 250 g/d in 500 mL of SM). Time changes after infusion in TFA contents were only observed for plasma C18:1 trans-4, trans-5 and trans-12, and high-density lipoprotein fraction C18:1 trans-9. After ruminal pulses, concentration of acetate decreased linearly; molar concentrations of propionate and valerate increased linearly; molar concentrations of butyrate and isovalerate changed quadratically and were greater at 1 h than at other times. There was an accumulation of several C18:1 TFA in plasma and lipoproteins, especially on the third day of pulsing. Overall, naturally occurring C18:1 TFA isomers (produced during ruminal biohydrogenation of SO) and preformed TFA (supplied by PHVO) elicited differential TFA partitioning and transport in plasma and lipoproteins.
