“…Approximately 100 mL of the fluid sample was stored at −30°C until subsequent analysis. For the analysis of volatile fatty acids (VFA), the rumen fluid samples were acidified with 1.5 mol/L sulfuric acid containing 12% metaphosphoric acid, and measured by gas chromatography as previously described (Shibata et al . 2011).…”

The effects of corn dried distillers grains with solubles (DDGS) feeding on rumen fermentation and milk production in cows were evaluated using diets high in neutral detergent fiber (NDF, 45.9-46.6%). The control diet (Control) consisted mainly of hay, corn silage and concentrates. In the experimental diets, the concentrates were replaced with DDGS as 10% dry matter (DM) (10%DDGS) and 20% DM (20%DDGS). Eight cows were used for each 14-day treatment period. Effect of DDGS feeding on DM intake was not significant. Ruminal volatile fatty acids and ammonia-N at 5 h after feeding of 20%DDGS were decreased compared to Control, whereas protozoal count at 2 h after feeding of 20%DDGS was higher than that of 10%DDGS. Milk yield of cows fed DDGS diets was greater than that of Control, although percentages of milk protein and solids-not-fat were decreased by DDGS diets. The proportions of C10:0, C12:0, C14:0 and C16:0 in the milk fat decreased, and those of C18:0, C18:1, C18:2 and cis-9, trans-11 conjugated linoleic acid (CLA) increased markedly with elevated DDGS. Increase in trans-11 C18:1 was observed in the rumen fluid at 5 h after feeding. These findings suggest that DDGS feeding enhanced milk yield, as well as CLA synthesis under a high dietary NDF condition.

“…1999; Belury 2002; Pariza 2004). There have been many attempts to increase milk CLA levels through increasing the fat content of the diet, and we previously reported that supplementation with soy sauce oil and Ca salts of fatty acids increased the CLA concentration in milk fatty acids (Shibata et al . 2011).…”

“…Cenkvári et al (2005) reported that when sheep were fed a diet composed of alfalfa hay and concentrate and supplemented with 75 g.day -1 of calcium salts of linseed oil (5.4% of dry matter), the total VFA concentration in the rumen fluid measured 3 h after feeding did not change, the acetate:propionate ratio decreased and the butyrate and valerate levels increased. Shibata et al (2011) reported that fed cows with 400 g.day -1 of CSFA had decreased total VFA 2 h after feeding with CSFA. Table 6.…”

Feeding goats with calcium salts of fatty acids (CSFA) can supply ruminants with lipids, with minimal effects on ruminal fermentation and fiber digestibility. However, there is a shortage of information on the effect of CSFA on characteristics of rumen fermentation in grassland goats. Thus, the present study aimed to assess the addition of CSFA to concentrate on the parameters of rumen fermentation of grazing goats. Five rumen cannulated goats were distributed in a Latin square 5x5 design (treatments: 0%, 1.5%, 3.0%, 4.5% and 6.0% CSFA. The pH, ammonia N and volatile fatty acids (VFA) content were analyzed in the ruminal fluid at 0, 2, 4, 6 and 8 hours after concentrate supplementation. The pH and ammonia N concentration showed a linear effect with the addition of CSFA. There was no effect observed for the VFA molar concentration after grazing goats were fed with the experimental diet. In conclusion, further research is needed to investigate the addition of CSFA to goat diets because there is evidence that CSFA increases ruminal pH and decreases excess ruminal ammonia without changing the VFA concentration in the rumen fluid.

“…Ruminal pH in the present study was within the optimal range (6.1-6.7) to ensure normal A c c e p t e d A r t i c l e growth of major rumen microbes [21], and other ruminal parameters including ammonia and VFA were not greatly affected by the administration of kg of soy sauce oil (Table 4). However, Shibata et al [14] reported that rumen fermentation was slightly inhibited by soy sauce oil at a lower level of administration (0.4 kg/d), as was observed for decreased VFA concentration. The reason for the different responses between the two studies is not clear, although the response in feed intake should be examined not by direct ruminal administration, but by a feeing study, and allowable supplementation levels should be proposed for the application of soy sauce oil.…”

“…Preliminary evaluation of soy sauce oil as a dietary lipid for ruminants was carried out by Shibata et al [14]. They indicated that soy sauce oil has no negative effect on dry matter (DM) intake, milk yield and composition, while the proportion of CLA in milk fat increased with ruminal administration of soy sauce oil at 0.4 kg/d.…”

Objective: To evaluate soy sauce oil (a by-product of making whole soybean soy sauce) as a new dietary lipid source, a large amount of soy sauce oil was administered into the rumen of dairy cows. Methods: Four Holstein dairy cows fitted with rumen cannulae were used in a 56-day experiment. Ruminal administration of soy sauce oil (1 kg/d) was carried out for 42 days from day 8 to day 49 to monitor nutritional, physiological and production responses. Results: Dry matter intake and milk yield were not affected by soy sauce oil administration, whereas 4% fat-corrected milk yield and the percentage of milk fat decreased. Although ruminal concentration of total volatile fatty acids (VFA) and the proportion of individual VFA were partially affected by administration of soy sauce oil, values were within normal ranges, showing no apparent inhibition in rumen fermentation. Administration of soy sauce oil decreased the proportions of milk fatty acids with a carbon chain length of less than 18, and increased the proportions of stearic, oleic, vaccenic and conjugated linoleic acids. Conjugated linoleic acid content in milk became 5.9-8.8 times higher with soy sauce oil administration. Blood serum concentrations of non-esterified fatty acid, 3-hydroxybutyric acid, total cholesterol, free cholesterol, esterified cholesterol, triglyceride and phospholipid increased with administration of soy sauce oil, suggesting a higher energy status of the experimental cows. Conclusion: The results suggest that soy sauce oil could be a useful supplement to potentially improve milk functionality without adverse effects on ruminal fermentation and animal health. More detailed analysis is surely necessary to optimize the supplementation level of this new lipid source in feeding trials.
