Manipulation of nutrient flow and digestion in defaunated sheep subjected to various dietary regimens
… to test the possibility of manipulating nutrient flow and digestion of defaunated sheep. The first study evaluated effects of urea (U) and sodium bicarbonate (B) supplementation. Control sheep were faunated (treatment 1), with soybean meal (SBM) as the major N supplement. Remaining sheep …

Varying rumen available carbohydrate and rumen available protein in diets of lactating cattle
… (RAP) on milk yield and milk composition, nutrient flow to the duodenum, ruminal and total tract nutrient digestibilities, and ruminal pH, ammonia-N, and VFA concentrations in lactating cows. The first study was a response surface design utilizing nine dietary combinations of RAC and RAP. …

Effects of source and amount of energy and protein on ruminal fermentation, nutrient passage to the small intestine, and performance of lactating Holstein cows
… and amount of energy and crude protein (CP) on nutrient flow to the duodenum. In each experiment, four Holstein cows were used in a 4 x 4 Latin square with treatments arranged in a 2 x 2 factorial.

Trojan horses in the marine realm: characterizing protistan parasite ecology in coastal waters
… and metabolically diverse drivers of energy and nutrient flow in the marine environment, with recent research suggesting significant roles in global carbon cycling throughout the water column. Top-down controls on planktonic protists include grazing and parasitism, processes that both contribute …

Lowering ruminally degradable protein in lacatating dairy cow diets
… protein yield, ruminal metabolism, passage of nutrients out of the rumen, and N excretion. The first study investigated the effects of decreasing RDP in lactating dairy cow diets on feed intake, milk production and apparent N efficiency. Forty mid-lactation cows (36 Holstein and 4 Jersey × …
