Abstract
The purpose of this study was to investigate the digestibility and the rumen fermentation patterns of an oyster shell ration when compared to other rations. To accomplish this, a 2 ½ oyster shell ration was fed in each of two experiments. The first experiment also utilized of 20% corn cob ration while the second experiment utilized an all-concentrate ration, a 2 ½ limestone ration and a 10% corn cob ration besides the 2 ½ oyster shell ration. In addition, the comparison between all-concentrate and the 10% roughage ration would give information upon ration digestibility.
For purposes of specific comparison, protein, organic matter, energy and ash digestibility were determined along with nitrogen, calcium and phosphorus retention.Comparisons in the rumen fermentation patters were made with lactic acid levels, protozoa number and pH.
