Wet vs. dry ad libitum feeding of growing-finishing swine

Glufosinate herbicide-tolerant (LibertyLink) rice vs. conventional rice in diets for growing-finishing swine.

Genetically modified (GM) rice (LibertyLink, event LLRICE62) that is tolerant to glufosinate ammonium (Liberty) herbicide was compared with a near-isogenic (NI) conventional medium-grain brown rice (cultivar, Bengal) and a commercially milled long-grain brown rice in diets for growing-finishing pigs. The GM and NI rice were grown in 2000. The GM rice was from fields treated (GM+) or not treated...

Feeding value of wet distillers byproducts for finishing ruminants.

Yearling and calf finishing trials (replicated over 2 yr) evaluated the feeding value of wet distillers byproducts (wet distillers grains and thin stillage). An additional trial estimated the amount of thin stillage bypassing the rumen when consumed by drinking. Yearlings were 5, 10, and 20% more efficient (linear, P < .01; quadratic, P = .05), whereas calves were 2, 6, and 14% more efficient (...

Effects of Programmed Feeding to a Constant Average Daily Gain vs. Ad Libitum Feed Intake on Performance and Carcass Characteristics of Finishing Beef Steers

Thirty-two Angus steers were used in a 140d feeding trial to examine the effects of ad libitum feed intake or a programmed rate of gain on feedlot performance and carcass characteristics. Ad libitum-fed steers had greater (P < .06) DMI, ADG, and feed efficiency from d 0 to 28, 0 to 56, and 0 to 84 than programmed-fed steers; however, no differences in ADG, DMI, or feed efficiency were detected ...

Effects of supplemental selenium on swine. II. Growing-finishing.

The effects of dietary selenium (Se), copper (Cu) and zinc (Zn) on growth characteristics, selected blood parameters and carcass traits in growing-finishing swine were evaluated in two experiments. In the first experiment, 48 Duroc barrows and gilts weighing approximately 30 kg were al lot ted by sex and weight to six dietary treatments. They were fed a basal 16% crude protein diet containing ....
