Effects of a specific blend of essential oil compounds on rumen fermentation
Autor: Freda M. McIntosh, Robert Wallace, Charles J. Newbold, P. E. V. Williams, Riccardo Losa
Publikováno v: Animal Feed Science and Technology. 114:105-112
Effects of a specific preparation of essential oil compounds on rumen fermentation were determined using four mature sheep, each fitted with a permanent rumen cannula and receiving 110 mg per day of dietary essential oils compounds (EO; CRINA RUMINAN

Publikováno v: Animal Science. 55:193-202
Forty-six Simmental × British Friesian bull calves were allocated to six treatment groups. In four groups (each of eight animals) half the animals were given a prime injection of gonadotropin-hormone-releasing-hormone (GnRH) either as the decapeptid

Feeding the young ruminant
Autor: A. I. Frost, P. E. V. Williams
Publikováno v: BSAP Occasional Publication. 15:109-118
Young calves and lambs are weaned early to reduce the amount of milk products consumed and potentially improve the profitability of rearing enterprises. At weaning the pre-ruminant must make a number of adjustments to cope with the change in dietary

Effects of Essential Oils on Ruminal Microorganisms and Their Protein Metabolism
Autor: Freda M. McIntosh, Charles J. Newbold, P. E. V. Williams, R. Losa, D. A. Beever, Robert Wallace
A commercial blend of essential oil (EO) compounds was added to a grass, maize silage, and concentrate diet fed to dairy cattle in order to determine their influence on protein metabolism by ruminal microorganisms. EO inhibited ( P < 0.05) the rate o

Optimal dietary concentration of vitamin E for alleviating the effect of heat stress on egg production in laying hens
Autor: P. E. V. Williams, S. Bollengier-Lee, C. C. Whitehead
Publikováno v: British poultry science. 40(1)
1. The effects of different dietary concentrations of vitamin E (alpha-tocopherol acetate) were investigated on laying hens exposed to chronic heat stress at 32 degrees C from 26 to 30 weeks of age. 2. Diets containing 5 dietary concentrations of vit

Influence of high dietary vitamin E supplementation on egg production and plasma characteristics in hens subjected to heat stress
Autor: M. A. Mitchell, C. C. Whitehead, S. Bollengier-Lee, P. E. V. Williams, D. B. Utomo
Publikováno v: British poultry science. 39(1)
1. The effects of different dietary concentrations of vitamin E (alpha-tocopherol acetate) were investigated in 2 experiments on laying hens exposed to chronic heat stress at 32 degrees C. 2. In the first experiment, egg production and plasma concent

Responses of meat-type chickens to choice feeding of diets differing in protein and energy from hatch to market weight
Autor: E. A. Dunnington, Paul B. Siegel, I. Nir, M. L. Picard, P. E. V. Williams, M. H. A. Willemsen
Publikováno v: Poultry science. 76(9)
Chickens from three genetic stocks known to differ in growth potential consumed ad libitum either a single (control) diet or a choice of two diets that differed in protein and energy. Formulation of the choice diets was such that when mixed in specif
