“…The cows receiving high concentrate diet consumed on average 24.0 kg DM per day whereas the cows receiving the low concentrate diet consumed 22.7 kg DM per day. Erasmus (1997) observed an average DMI of 22.2 to 24.6 kg/day and Mutsvangwa et al (2002) reported a DMI of 22.1 to 23.0 kg/day in early lactating Holstein cows on lucerne based TMR's which is in agreement with results from this study. Aikman et al (2008) conducted a trial to determine the effect of Me on the productivity of early lactation Holstein cows with two TMR's differing in level of concentrate.…”

________________________________________________________________________________ AbstractSixty high-producing multiparous Holstein cows were used in a randomized complete block design experiment to determine the effect of a direct-fed microbial (DFM), Megasphaera elsdenii NCIMB 41125 (Me), on dairy cattle productivity and health. The cows received one of two experimental diets (total mixed rations (TMR)) from calving until 60 days post partum. Two experimental diets were formulated, namely a low concentrate diet (40% roughage : 60% concentrate) and a high concentrate diet (30% roughage : 70% concentrate) that were fed as a TMR for the duration of the trial. The low and high concentrate diets contained respectively 181 g/kg and 178 g/kg of crude protein, 448 g/kg and 504 g/kg of non-fibre carbohydrate, 282 g/kg and 238 g/kg of neutral detergent fibre and 42 g/kg and 43 g/kg of ether extract. There were four experimental treatments, namely: (1) Low concentrate diet control (LCC), (2) Low concentrate diet and dosed with Me (LCD), (3) High concentrate diet control (HCC) and (4) High concentrate diet and dosed with Me (HCD). Dosing with Me did not show any advantage, regardless of level of concentrate. Dry matter intake, milk production, milk composition, feed efficiency, body mass and body condition score were not affected by treatment. Furthermore, treatment did not affect rumen pH, rumen lactic acid or volatile fatty acid concentrations. Faecal pH, however, was statistically significantly higher, and faecal starch content significantly lower in cows dosed with Me. Lack of results suggests that further research is needed on dose time and/or frequency as well as the option to use it as an infeed product. ________________________________________________________________________________

“…Therefore, it is a major concern to prevent or alleviate the occurrence of SARA in dairy herds. In the past decade, several dietary strategies proposed for use in preventing SARA, such as sodium bicarbonate buffer and monensin iono-phones as well as probiotics, have been found to stabilise ruminal pH and improve animal production (Mutsvangwa et al 2002;Paton et al 2006;Chaucheyras-Durand et al 2008;Desnoyers et al 2009;Packer et al 2011). However, none of these approaches has consistently maintained higher and stable ruminal pH.…”

Effects of different dietary concentrate to forage ratio and thiamine supplementation on the rumen fermentation and ruminal bacterial community in dairy cows

Abstract.A subacute ruminal acidosis (SARA) model was induced gradually by increasing the proportion of dietary concentrate to evaluate the effect of thiamine supplementation on the structure of bacterial community in dairy cows. Three Holstein dairy cows with rumen cannula were randomly assigned to a replicated 3 · 3 Latin square design trial and received three diets during three successive 21-day periods in each square. The three dietary treatments were as follows: a lowconcentrate diet (control), a high-concentrate SARA-induced diet (SARA) and a high-concentrate SARA-induced diet with 180 mg thiamine/kg DM (SARA+thiamine). Real-time-polymerase chain reaction assay was used to quantify the population variation of SARA-related ruminal bacteria in these cows. The results showed that SARA was induced gradually when cows were fed with the high-concentrate diets. The mean ruminal pH value was higher in the control cows than in those of SARA and SARA+thiamine groups, the mean was decreased in cows fed on SARA diet, and the depression was alleviated by supplemented thiamine and the difference was significant (P < 0.05) especially at 9-h and 12-h sample times (or 1 h and 4 h after the second feeding). The populations of Streptococcus bovis and genus Lactobacillus in cows from the SARA group were increased in log copies/mL by 3.62% and 4.65%, respectively, compared with the control group (P < 0.05). In contrast, in log copies/mL, populations of Butyrivibrio fibrisovens and Megasphaera elsdenii were decreased by 1.14% and 4.90%, respectively (P < 0.05). Thiamine supplementation led to an obvious reduction of Strepococcus bovis and Lactobacillus (P < 0.05), whereas the number of log copies/mL of Megasphaera elsdenii was dramatically increased (P < 0.05). There was no significant effect of thiamine supplementation on the number of log copies/mL of Butyrivibrio fibrisovens and Selenomonas ruminantium (P > 0.05). It was concluded that thiamine supplementation to high-concentrate diets at concentrations of 180 mg/kg DM could help alleviate SARA by increasing rumen pH and balancing the population of lactic acid-producing and -consuming bacteria.

SummaryThe aim of this study was to explore the relationships between a Gram-positive bacterial population and methane production in the rumen of dairy cows supplemented with monensin and tallow, alone or in combination. Under each treatment condition, the following ruminal fermentation parameters were measured: pH, oxidationreduction potential (ORP), VFA, and methane production. Quantification of Gram-positive bacteria present in the rumen was performed by amplifying the 16S rDNA gene using PCR. Diversity analysis of Gram-positive bacteria was performed by PCR-denaturing gradient gel electrophoresis (DGGE), and bacterial taxonomy data were obtained by bioinformatics tools. Neither additive affected the pH or ORP, but they both reduced the total quantity of VFA. Supplementation with monensin, tallow, or their combination caused a decrease in methane production compared to the control diet. The best treatment to reduce methane production was monensin, with a reduction of 7.2% compared to the control diet. Supplementation with monensin or tallow did not affect the bacterial population. The Shannon diversity index was higher with monensin supplementation than with the other treatments. The analysis of each DGGE microbial community by the unweighted pair group method with averaging (UPGMA) revealed two clusters, one group with the control and monensin diets and the other with the tallow and combination diets. Taxonomic analysis of the dominant bands from the DGGE gel with the use of the Ribosomal Database Project (RBP) revealed that the Ruminococcaceae family was predominant, followed by the Lachnospiraceae family. Correspondence analysis (CA) suggested that both were negatively correlated with methane production in all treatments.
