Dietary tryptophan effects on plasma and salivary cortisol and meat quality in pigs1,2

Autor: A. C. Guzik, L. L. Southern, Brian J. Kerr, T. D. Bidner, J. O. Matthews

Publikováno v: Journal of Animal Science. 84:2251-2259

Four experiments were conducted to determine the effects of supplemental Trp on meat quality, plasma and salivary cortisol, and plasma lactate. Experiment 1 was a preliminary study to measure plasma cortisol concentrations in 4 barrows (50 kg of BW)

Effects of supplemental L-tryptophan on serotonin, cortisol, intestinal integrity, and behavior in weanling piglets1,2

Autor: J. van der Meulen, L. L. Southern, Brian J. Kerr, A. C. Guzik, Rienk Dekker, S.J. Koopmans, J. Kogut

Publikováno v: Journal of Animal Science. 84:963-971

Stress occurs in intensive pig farming when piglets are weaned and mixed. In this study, we investigated whether this stress might be reduced with elevated dietary levels of Trp. The effects of supplemental dietary Trp (5 g/kg of feed, as-fed basis)

Publikováno v: Journal of Animal Science. 83:1303-1311

Five experiments were conducted to determine the true ileal digestible Trp (tidTrp) requirement of growing and finishing pigs fed diets (as-fed basis) containing 0.87% (Exp. 3), 0.70% (Exp. 4), 0.61% (Exp. 5), and 0.52% (Exp. 1 and 2) tidLys during t

Autor: B. J. Kerr, L. L. Southern, T. D. Bidner, A. C. Guzik

Publikováno v: Journal of Animal Science. 80:2646-2655

Five experiments were conducted to determine the true digestible Trp (dTrp) requirement of nursery pigs. Treatments were replicated with four or five pens of five or six pigs each. Pigs were weaned at 21 (Exp. 1, 2, and 5) or 19 d (Exp. 3 and 4), and
