A series of lactation studies reported in this dissertation hypothesized that supplementing different rumen modifiers would have consistent responses on ruminal fermentation and lactational performance under optimal rumen conditions.
The first experiment investigated the influence of magnesium exchanged zeolite on ruminal fermentation and lactational performance. Intake of dry matter (DM), milk yield, milk fat, and feed efficiency were not affected. Milk protein concentration tended (P = 0.15) to be higher for cows fed the zeolite. Ruminal pH tended to increase (P = 0.11) by feeding the sodium bicarbonate or the zeolite.
A second lactation experiment determined …
