Lactic Acid Content

<p>Feed intake, general condition, rumenal pH and lactic acid content was followed during feeding of starved reindeer on a coventional diet (RF-71). The result was a dramatic decrease of rumen pH (pH=5.1 in experiment no. Ill) a few hours after feeding of the coventional diet, but this could be counteracted significantly by addition of buffer (pH=6.4 in experiment no. Ill) of hydrogenated marine oil (pH=6.1 in experiment no. Ill) to the ration. The highest content of the lactic acid in the rumen was 40 mM in animals fed RF-71, whereas addition of buffer or hydrogenated marine oil completely supressed accumulation of this acid.</p><p>Foropptak, pH og melkesyre i vomma hos rein under overgangsforing med kraftfor tilsatt buffer og fett.</p><p>Abstract in Norwegian&nbsp;/ Sammendrag: Forinntak, almentilstand, pH og melkesyreinnhold i vom ble registrert under foring av sultede rein med konvensjonelt kraftfor (reinfor 71 = RF-71).

Comprehensive Study

This study provides important information about the impacts of various levels of oat (OBG) and bacterial (curdlan) β-glucan and fat contents in milk on survivability and metabolism of yogurt starter cultures. The results show that addition of β-glucans in the concentration higher than 0.25% reduced starter bacterial counts during storage and prolonged the milk acidification process. A significant increase in lactose consumption by starter cultures was noted in the yogurt samples with OBG addition up to 0.75%. The highest (by 567% on average) increase in lactic acid content was noted in the control yogurts. Whereas the lowest (by 351%) increase in lactic acid content was noted in yogurts with OBG. After 28-day storage, the acetic aldehyde content was significantly influenced by fat content, type and addition level of polysaccharide. A higher increase in acetoin content was noted in samples with 0.25% than in samples with 1% of polysaccharides. In turn, significantly lower increases in diacetyl and 2,3-pentanedione contents were observed in the yogurt samples with OBG than in these with curdlan, with diacetyl production increase along with the higher concentration of the polysaccharide. The addition of OBG and curdlan to milk contributed to differences in the starter culture metabolism, consequently, in the milk acidification dynamics.

Lactic Acid Content

Tetanic contraction of mammalian muscle under essentially anaerobic conditions was found to result in marked increase in the pyruvic acid content as well as in the lactic acid content. The increase in lactic acid content was proportionately greater than in the pyruvic acid content. Repeated single twitches at a rate of 1/sec., continued long enough to produce a steady state, resulted in only a slight increase in pyruvic acid content, with a marked decrease in the ratio of pyruvic to lactic acid. The pyruvic acid formed during the steady state of activity appears not to pass into the blood stream.
