“…Of secondary interest in these investigations was the observation that simultaneous sodium bicarbonate and lactic acid supple mentation resulted in formic acid accumulations that were otherwise not evident. This observation tends to confirm the suggestion of Jamieson (1959) Phllllpson (1952) observed that cobalt supplementation of a cobalt deficient diet narrowed acetate-propionate ratios and lowered butyric acid levels. A similar ruminai fermenta tion pattern was observed in a single flstulated lamb trial.…”

“…Jamieson (1959) Holding the guide tube secure, tension was placed on the suc tion line, drawing the strainer out of the rumen, up the esophagus until it butted up against the guide tube, at which time the complete assembly was withdrawn from the animal.…”

“…1959 (1952) and Jamieson (1959) found that ruminai ammonia nitrogen values showed a highly significant correlation with concentrations of iso-butyric, 2-methylbutyric and iso-valeric acids. Shazly (1952) con cluded that the power of microbes to decompose amino acids to ammonia and volatile fatty acids increased with elevated soluble protein diet levels.…”

“…Ruminai fermentation patterns observed in fistulated lambs that were off feed as well as those of Jamieson (1959) Higher ration concentrate levels resulted in increased feed efficiency, carcass grade, dressing per cent and separ able fat and decreased separable lean. Narrower acetatepropionate ratios, higher butyric acid levels, lower total volatile fatty acid and pH levels were noted in the high than in the low concentrate rations.…”

“…Jamieson (1959) reported that excessive ruminai ammonia levels were of course toxic to ruminants and produced narrowed acetate-propionate ratios. Burroughs et al (i960) concluded that antibiotic supplementation most often shows a response for ruminants in a high roughage type ration.…”

1. Africander and Mashona steers, fitted with rumen cannulae, were used to study levels of various nitrogenous fractions and of dry matter in the rumen of cattle grazing on natural subtropical herbage throughout the year. Some steers received various concentrate foods in addition to veldt grazing during winter. During the summer rainy season, four steers, two of each breed, were under trial, while in the winter drought period two extra steers of each breed were added to the experiment. The eight steers were divided into four groups for the winter, one group received a protein-rich concentrate, another group received a carbohydraterich concentrate, a third group was given a mixture of the two concentrates, while the fourth group received no additional food.
