“…However, Radev (2012) found that dietary supplementation with DDGS increased rumen ammonia concentration in sheep. Similar effect was reported by Loy et al (2007) in the in vivo study in heifers. Converse results were obtained by Li et al (2014) who proved that feeding DDGS to laying hens resulted in 14% fall in ammonia emission.…”

“…Similarly, replacement of silage or barley grain with DDGS did not affect the total production and changes in the profile of SCFAs in the rumen of cows (Zhang et al 2010). The results of other studies showed that increasing DDGS content in the fermentation substrate lowered acetate with an increase in propionate and butyrate rumen production , Loy et al 2007. The in vitro studies showed that the use of DDGS decreased acetate and propionate levels in lambs (Behlke 2007).…”

The aim of the in vitro study was to determine the effect of corn dried distillers grains with solubles (corn DDGS), used as a replacement for the concentrate ingredients of sheep diet, on rumen fermentation. The material for the study was the ruminal fluid of Polish Merino sheep which was incubated during 4-, 8-or 24-hour periods. Five groups of samples were prepared for in vitro fermentation: C -control, incubated with the substrate consisting of the concentrate ingredients; D1, D2 and D3, where DDGS was used as a substrate added in proportions of 10, 20 and 30% of dry matter of the concentrate; and D4, where 100% DDGS was used as a substrate. After fermentation, the gas and short chain fatty acids (SCFAs) analyses were performed using gas chromatography. The ammonia concentration and pH were also determined, and the SCFA utilization index (NGR), the fermentation efficiency (FE) and the index of cell yield of ruminal microorganisms (CY) were calculated. This research showed no effect of DDGS on the methane emission. The positive correlations between the amount of methane and ammonia concentrations in the 8-and 24-hour fermentation periods were found. DDGS addition increased propionate proportion, but decreased production of acetate (p<0.01). Additionally, D1, D2, D3 and D4 substrates lowered isobutyrate (p<0.05) and isovalerate (p<0.01) production. Based on the results obtained, it can be stated that partial substitution of the concentrate ingredients with DDGS did not have deleterious effect on sheep rumen fermentation processes.

“…Given these calculations, the TDN value of DRC decreased from 90% at the LOW supplement concentration to 81% at the HIGH supplement concentration. This is likely due to the negative effect of starch and pH on cellulolytic activity (Loy et al, 2007). Although the decline in TDN was charged to the corn in our cal- culations, the decline in digestibility (TDN) was likely due to a decline in the digestibility of fiber of the hay.…”

“…We theorize that this decline is due to the fat content of the DDGS and the subsequent effect on ruminal cellulolytic activity (Loy et al, 2007). The fat of the HIGH DDGS diet was about 5.2%.…”

Crossbred heifers (n = 120; 265 kg, SD = 37) were fed individually (84 d) to determine the effect of supplement type, concentration, and frequency on intake and performance and to estimate the energy value of dry distillers grains plus solubles (DDGS) in a high-forage diet. Treatments were arranged in a 3 × 2 × 2 factorial, with 3 supplements, 2 concentrations, and 2 frequencies of supplementation. Supplements including dry-rolled corn (DRC), DRC with corn gluten meal (DRC + CGM), and DDGS were fed at 0.21% (LOW) or 0.81% (HIGH) of BW daily and were provided daily (DAILY) or 3 times weekly (ALT). Heifers were fed to consume grass hay (8.7% CP) ad libitum. Individual DMI, diet composition, BW, and ADG were used to calculate energy values for DDGS and DRC. Supplement type, concentration, frequency, and interactions were tested using the MIXED procedure of SAS, with BW included as a covariate. Supplement × concentration interactions for gain (P = 0.01) and G:F (P < 0.01) were detected. At the LOW concentration, heifers supplemented with DDGS gained more and were more efficient (P ≤ 0.03) than those supplemented with DRC or DRC + CGM. No performance differences were observed (P ≥ 0.22) between DDGS and DRC + CGM in HIGH treatments, although both improved (P ≤ 0.01) gain and G:F relative to DRC. Calculated TDN content of DDGS was 18 to 30% greater than DRC. Gain and G:F were improved (P < 0.01) in heifers fed HIGH vs. LOW. Total intake was greater (P < 0.01) for HIGH than LOW, but LOW heifers consumed more hay (P < 0.01) than HIGH. The DAILY heifers consumed more (P < 0.01) hay and total DM than the ALT heifers. The DAILY heifers gained more (P < 0.01) than ALT, but G:F was not affected (P = 0.85) by supplementation frequency. In a high-forage diet, DDGS has greater energy value than corn.

“…However, ethanol production from corn grain has made dried distillers grains (DDG) an available feedstuff that improves growth rate of grazing cattle (Griffin et al, 2012). In addition to demonstrating an increase in animal performance, previous research has demonstrated a substitution effect on forage intake when DDG is fed in forage-based diets (Loy et al, 2007;MacDonald et al, 2007;Griffin et al, 2012). If the cost of DDG is less than the cost of replaced grazed forage on a per unit of energy basis, then cost of production could be decreased by feeding DDG.…”
