The effect of dietary selenium on humoral immunocompetence of ponies
Autor: W. J. Tyznik, D A Knight
Publikováno v: Journal of animal science. 68(5)
Fifteen Shetland ponies were used in a 7-wk trial to study the effect of supplemental Se on humoral antibody production. Four 3-yr-old, five 2-yr-old and six yearling ponies were depleted of Se before being assigned randomly to either a low Se (.02 p

Publikováno v: Applied and Environmental Microbiology. 54:1946-1950
Microbial numbers, pH, fluid volume, and turnover rate in the pony cecum were measured during an abrupt change from an all-forage to an all-concentrate diet, both fed at maintenance energy levels. Concentrate feeding resulted in increased (P less tha

Autor: D. A. Knights, W. J. Tyznik
Publikováno v: Journal of Animal Science. 60:1-5
Fourteen Quarter Horse foals were used to evaluate the effects of artificial rearing on growth. Seven foals were removed from their dams at 3 d of age and fed a reconstituted 26% crude protein (CP) milk replacer free choice for 1 mo, at which time ad

Cultivation of Rumen Protozoa. I. Factors Influencing the Cultivation of Rumen Oligotrich Protozoa 'In Vitro'
Autor: S. A Rahman, W. J. Tyznik, D. B. Purser
Publikováno v: The Journal of Protozoology. 11:51-55
SYNOPSIS. Factors influencing the cultivation of entodinia in vitro have been studied. It was found that removal of particulate material, culture division, or a combination of both resulted in similar maximum protozoal concentrations. At the same tim
