Observations were made on silage pH, chemical composition and 24hr in vitro dry matter digestion (IVDMD) to evaluate effects of various additives ensiled with annual ryegrass straw. Additives were compared in factorial designed trials utilizing .95 1 glass jar silos. Selection of additives used in each subsequent trial was based...
A series of in vitro laboratory trials and in vivo
sheep digestion trials were used to evaluate aerobically
or anaerobically fermented perennial ryegrass straw.
The laboratory trials consisted of a silage study, where
mini-silos were used in a 9 X 2 factorial design with
nine levels of whey (0 to...
Some effects of hormone treatment on feedlot heifers were
studied. The treatments were 15 mg diethylstilbestrol (DES) implant,
Synovex H implant, .25 mg oral melengestrol acetate (MGA)
per head per day, and .40 mg oral MGA per head per day. One
hundred heifers, 20 to each treatment, were used. All...
Six experiments were conducted to determine the effects of
DES implantation on preweaning performance and sexual maturation
of male calves when implanted at various stages of development and
different sites.
Calves receiving DES implants in Experiments I and II were
implanted at birth, at birth and at about three months...
Seven in vitro trials were conducted to compare the effects of
soaking annual ryegrass straw in solutions of sodium hydroxide (Na₄OH),
potassium hydroxide (KOH), ammonium hydroxide (NH₄OH), or sodium
formate (NaCHO₂) at varying levels. Dry matter digestibility (DDM)
was the criterion used to measure treatment response. A 3 x 3...
The objective of this study was to compare the total collection
(in vivo), nylon bag, and in vitro digestibility techniques under
standardized conditions. Twin steers were used simultaneously to
measure the digestibility of five rations consisting of the following
ratios of alfalfa hay to steamed roller barley: 4:0 (I), 3:1...
Three trials with wethers and four trials with steers were
conducted to determine some of the effects of sodium bicarbonate,
calcium hydroxide and/or transfer of ruminal contents on ruminant
adjustment to abrupt changes to concentrate rations.
Lambs fed a basal concentrate diet plus sodium bicarbonate had
the highest average feed...
