“…The propionic acid is the main source of liver gluconeogenic substrate, and the ruminal propionic acid ratio was increased with NAM supplementation, suggesting the improved gluconeogenesis might be due to increased gluconeogenic substrate. This was in accordance with the result in Khan et al [13] The increased propionic acid could be due to the altered NAD/NADH ratio in microbes, as NAM is a precursor of NAD. Another reason would be that niacin increased rumen protozoa numbers [14], which was shown to contribute to higher ruminal propionic acid level [15].…”

Background: Improving energy efficiency is urgent during perinatal period because dairy ruminant is often in negative energy balance, resulting many metabolic disorders thus economic losses. It has been previously highlighted that nicotinamide (NAM) supplementation during perinatal period could benefit the energy balance, while the underlying metabolic alterations and the differences in NAM supplemented during different perinatal period have been poorly studied. This study aimed to elucidate the effects of NAM on energy efficiency, lipid metabolism, oxidative status, and liver metabolites profile of perinatal does during different perinatal period. Results: Fifteen multiparous does with similar parity, weight, and previous milk yield were paired and allocated to 3 groups (n = 5): control (C), postpartum supplementation (P, NAM supplemented after kidding), and entire-perinatal supplementation (EP, NAM supplemented from -21 to 28 d around kidding). Does were drenched with 5 g/d of NAM and slaughtered on d 28. The ruminal acetic acid tended to decrease, and the propionic acid and valeric acid were increased in P and EP. The does in P and EP had a decreased acetic acid to propionic acid ratio. Does in EP had higher liver mitochondrial respiratory chain complexes. The Complex Ⅱ was elevated in both P and EP and NAM supplementation tended to increase ATP production. Liver metabolomics analysis and tissues biochemical analysis revealed that lipid was decomposed in abdominal adipose, and in liver, the decomposition of lipid was more than the synthesis, and the amino acid metabolism were enriched by NAM. Moreover, the oxidative status of blood and liver were improved by NAM supplementation, and supplementation of NAM during postpartum only does not appear enough to cope with the metabolites of oxidative phosphorylation. Conclusions: Overall, these data suggested that NAM supplementation during perinatal period favored the rumen fermentation pattern to propionic acid-type, and improved liver energy efficiency with benefited lipid metabolism. The NAM supplemented from prepartum is needed for better oxidative status and energy metabolism of perinatal does.

“…They reported that the NH 3 -N was higher (P<0.05) in the rumen liquor of the buffaloes fed P. minor seeds as compared to that in control group. The NH 3 -N production, in the present study, is within the normal range as reported Khan et al, (2015) for TMRs having roughage to concentrate ratio of 60:40.…”

“…They reported that replacement of wheat grains by P. minor seeds up to 75% in concentrate mixture as well as inclusion of higher levels of P. minor seeds up to 60% in the concentrate mixture, showed no adverse effect on the TVFA concentration in the rumen. The TVFA levels in the present study were within the normal range as reported by Khan et al, (2015) who carried out in vitro evaluation of TMRs having roughage to concentrate ratio of 60:40. However, the values of TVFAs in the present study were lower than those reported by Ahmed (2013) from TMRs with roughage to concentrate mixed in the ratio of 60:40.…”

“…The CY increased the concentrations of serum urea-N by 8% may be related to a probable increased in ruminal ammonia-N, as indicated in the in vitro experiment. Moreover, feeding S. cerevisiae may have increased vitamin B (Ogunade et al, 2019) which may be linked to a positive influence on liver metabolism (Khan et al, 2015). Moreover, increased urea-N in cow's serum suggests increased N wastage either at digestive or at metabolic levels (Patra and Aschenbach, 2018).…”

This study compared the effects of feeding a new strain of Saccharomyces cerevisiae HSA2020 with a commercial strain on in vitro rumen fermentation and production performance of dairy cows. Permeate was used as a substrate for the laboratory production of the new strain of S. cerevisiae after the hydrolysis by β–galactosidase (5000 µ/mL at 37°C). Two experiments were conducted: in Experiment 1, the effects of three levels (1, 2 and 3 g/kg dry matter) of S. cerevisiae on in vitro ruminal fermentation kinetics were evaluated. In Experiment 2, for 60 days, sixty multiparous Holstein cows (639±24.8 kg BW, 3±1 parity, 7±1 days in milk, with a previous milk production of 23±2.0 kg/d) during the previous lactation, were randomly assigned to 3 treatments in a completely randomized design. Cows were fed without any additives (control treatment) or supplemented with 2 g/kg feed daily of laboratory produced (PY)or commercial (CY) S. cerevisiae. In Experiment 1, inclusion of PY and CY increased (P<0.05) gas production, propionate, and nutrient disappearance, while decreased (P<0.05) methane production and protozoal count. Moreover, in Experiment 2, PY followed by CY increased (P<0.01) nutrient digestibility, and serum concentrations of total protein, albumin, and glucose (P<0.05). Higher daily milk yield, and milk energy output were observed with PY and CY without affecting concentrations of milk components or milk fatty acid profile. Compared to control, increased feed efficiency was observed with PY and CY. Compared to PY, CY increased serum concentrations of urea-N and decreased triglycerides, while PY decreased serum aspartate transaminase and increased concentration of conjugated linoleic acids in milk. In early lactating cow diets, both strains of S. cerevisiae improved production performance at 2 g/kg improved production performance, and minimal differences between strains were found.
