Myrie S, Bertolo R, Sauer W, Ball R
J Anim Sci
. 2007 Nov;
86(3):609-19.
PMID: 17998420
Most feedstuffs contain antinutritive factors (ANF) such as insoluble fibers, lignins, tannins, and lectins. Intake of these ANF has the ability to reduce nutrient digestibility and to increase endogenous protein...

J Anim Sci
. 2005 Oct;
83(11):2535-42.
PMID: 16230650
Although AA requirements for the mean in a population of growing pigs are well established, there are no direct estimates of their variability within the population. The indicator AA oxidation...

Bertolo R, Brunton J, Pencharz P, Ball R
Pediatr Res
. 2000 Oct;
48(5):701-7.
PMID: 11044495
Kinetics studies in neonates are important to establish the requirement for amino acids and to understand the mechanisms of normal and altered metabolism. During kinetics experiments, plasma amino acid concentrations...

Bertolo R, Pencharz P, Ball R
J Nutr
. 2000 May;
130(5):1261-6.
PMID: 10804082
In a previous study in piglets fed identical diets intravenously, intraportally or intragastrically, we determined that small intestinal atrophy affects nitrogen metabolism to a greater extent than liver by-pass. Because...

Brunton J, Bertolo R, Pencharz P, Ball R
Am J Physiol
. 1999 Aug;
277(2):E223-31.
PMID: 10444416
The indispensability of arginine has not been conclusively established in newborns. Because parenteral feeding bypasses the gut (where de novo synthesis of arginine occurs from proline), a dietary supply of...

J Nutr
. 1999 May;
129(5):1045-52.
PMID: 10222398
Whole-body nitrogen metabolism is altered during parenteral feeding as a result of gut atrophy and/or lack of splanchnic first-pass metabolism. We developed in vivo models to describe the metabolic and...

Bertolo R, Pencharz P, Ball R
JPEN J Parenter Enteral Nutr
. 1999 Mar;
23(2):47-55.
PMID: 10081992
Background: The amino acid requirement profile for infants is different than that for adults and needs to be established; this profile also is different for infants receiving total parenteral nutrition....

Bertolo R, Chen C, Law G, Pencharz P, Ball R
J Nutr
. 1998 Oct;
128(10):1752-9.
PMID: 9772146
Evidence is accumulating that the amino acid requirements for neonates receiving total parenteral nutrition (TPN) are significantly different than those for oral feeding and need to be determined. The parenteral...

Pediatr Res
. 1993 Feb;
33(2):118-24.
PMID: 8433886
Premature infants receive high dietary zinc and often glucocorticoids as a treatment for chronic lung disease. A piglet model was developed to investigate intestinal zinc transport and distribution of tissue...
