[QUOTE="dcara, post: 290646, member: 473"] One of the papers I read on the subject discussed the efficency of the rumen microbes (both fiber eaters and starch eaters) as a function of the rumen PH level which is affected by the DM vs. CP ratio. In short, maximum rumen effeciency is obtained when there is a "proper balance" (not an equal balance) of the 2 different types of microbes. Some research suggests that for forage based diets this occurs with a DM/CP ratio of about 6:1 to 8:1. If the forage ration yields lower than this ratio then additional energy (i.e grains) can be added to the ration which well result in better rumen efficency and hence better ADG. If the forage ratio is higher then CP should be added to the ration. Adding energy to a ration that already has a high DM/CP ratio results in further decreased rumen efficency and energy "substitutaion" at less than a 1:1: rate. That is, they eat less forage due to the grain substituting their energy needs, BUT, since the rumen is now less efficient their overall energy uptake is less and hence ADG can fall off. [/QUOTE]
