Effects of cottonseed meal supplementation time on ruminal fermentation and forage intake by Holstein steers fed fescue hay

Autor: J. T. Broesder, L J Krysl, Stacey A. Gunter, M B Judkins, R. K. Barton, D W Holcombe

Publikováno v: Journal of Animal Science. 69:3789-3797

Four ruminally cannulated Holstein steers (average BW 303 kg) were used in a 4 x 4 Latin square design digestion trial to study the influence of daily cottonseed meal (CSM; 1.6 g of CP/kg of BW) supplementation time on forage intake and ruminal fluid

Influence of alkaloid concentration of tall fescue straw on the nutrition, physiology, and subsequent performance of beef steers

Autor: S. D. Brandyberry, Timothy DelCurto, M. M. Stamm, M. R. Horney, R. K. Barton

Publikováno v: Journal of animal science. 72(4)

Two experiments were conducted to evaluate digestion, performance, and physiological responses to Acremonium coenophialum-infected tall fescue straw offered to vary ergovaline concentrations. In Exp. 1, 16 Hereford x Angus ruminally cannulated steers

Influence of branched-chain fatty acid supplementation on voluntary intake, site and extent of digestion, ruminal fermentation, digesta kinetics and microbial protein synthesis in beef heifers consuming grass hay

Autor: L J Krysl, J. T. Broesder, M B Judkins, R. K. Barton, Stacey A. Gunter

Publikováno v: Journal of animal science. 68(9)

Four heifers (British x British; average BW 372 kg) cannulated at the rumen and duodenum and consuming a grass hay (fescue-orchardgrass) diet were used in a 4 x 4 Latin square and supplemented with four levels (0, 20, 40, and 60 g.head-1.d-1) of supp

Digesta kinetics, ruminal fermentation characteristics and serum metabolites of pregnant and lactating ewes fed chopped alfalfa hay

Autor: J. T. Broesder, B. R. Rueda, R. K. Barton, M B Judkins, D. M. Hallford, L J Krysl, D W Holcombe, Stacey A. Gunter

Publikováno v: Journal of Animal Science. 68:3821

Eight ruminally cannulated ewes (four control and four bred; average BW = 85.7 kg), limit-fed alfalfa hay (1.86% BW), were used in two experiments to determine the effects of pregnancy and lactation on digestive function and serum metabolites. Seven-

Thirty or sixty percent milk replacer reduction for calves: effects on alfalfa hay intake and digestibility, digestive kinetics and ruminal fermentation

Autor: L J Krysl, R. K. Barton, J. T. Broesder, M B Judkins, Stacey A. Gunter

Publikováno v: Journal of Animal Science. 68:2974

Twelve artificially reared, male Holstein calves, ruminally cannulated at 53 d of age, were used in a split-plot design to study the effects of no milk replacer reduction (CON), or reduction by 30% (30R) or 60% (60R) of this value on alfalfa hay inta

Estimating diet digestibility: a comparison of 11 techniques across six different diets fed to rams

Autor: L J Krysl, R. K. Barton, M B Judkins

Publikováno v: Journal of Animal Science. 68:1405

Six digestion trials were conducted using eight Suffolk rams (four/trial; two trials run concurrently) to determine the ability of 11 techniques to estimate in vivo apparent DM digestibility (DMD). Diets (trials) were as follows: 1) ad libitum access
