A comparison of in vivo and in vitro techniques for the evaluation of varying roughage-concentrate rations

Creator:

Klett, Ramon Hollis

Abstract:

The objective of this study was to compare the total collection (in vivo), nylon bag, and in vitro digestibility techniques under standardized conditions. Twin steers were used simultaneously to measure the digestibility of five rations consisting of the following ratios of alfalfa hay to steamed roller barley: 4:0 (I), 3:1...

Ruminant and microbial physio-chemical response to abrupt ration changes as influenced by chemical and/or biological means

Creator:

Patton, Westley R.

Abstract:

Three trials with wethers and four trials with steers were conducted to determine some of the effects of sodium bicarbonate, calcium hydroxide and/or transfer of ruminal contents on ruminant adjustment to abrupt changes to concentrate rations. Lambs fed a basal concentrate diet plus sodium bicarbonate had the highest average feed...
