Effects of Franklin Feed-Grade Limestone vs. Aerion Industries Nutrion Limestone on performance and carcass characteristics of finishing beef steers
نویسندگان
چکیده
Because grains comprise the major portion of diets for finishing beef cattle, and grains contain little calcium, limestone is typically added to finishing diets at levels of .7 to more than 1% of the dry matter. Feedgrade limestone varies in quality and consistency, which could alter performance responses by finishing beef steers. Selection of superior sources of limestone and(or) treatment of selected limestones to increase their reactivity in the gastrointestinal tract, might alter the supply of available calcium. Our objective was to determine whether performance and carcass characteristics of finishing beef steers differed when a select source of treated limestone (Aerion Industries Nutrion limestone) was fed at two levels compared with a common feed-grade source of limestone.

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 ...
متن کاملSupplemental betaine and peroxide-treated feather meal for finishing cattle.
These studies evaluated the effects of betaine, provided either as feed-grade betaine or as concentrated separator by-product (CSB; desugared beet molasses), on performance and carcass characteristics of finishing cattle. In Exp. 1, 175 steers (410 kg initial BW) were fed a finishing diet based on steam-flaked and dry-rolled corn, and treatments included 10.5 and 21 g/d feed-grade betaine and 2...
متن کاملA dose-response study of melengestrol acetate on feedlot performance and carcass characteristics of beef steers.
The dose response of melengestrol acetate (MGA) on ADG (kg/d) and gain efficiency (gain/DMI, g/kg) was estimated in beef steers fed a finishing diet under commercial feedlot conditions. Melengestrol acetate is not approved for use in steers as a feed additive. The study design was five blocks of four pens (each pen was assigned a dose of MGA) with 166 to 200 steers per pen. Melengestrol acetate...
متن کاملComparison of alternative beef production systems based on forage finishing or grain-forage diets with or without growth promotants: 1. Feedlot performance, carcass quality, and production costs.
Forty Angus-cross steers were used to evaluate 5 beef cattle management regimens for their effect on growth performance, carcass characteristics, and cost of production. A 98-d growing phase was incorporated using grass silage with or without growth promotants (trenbolone acetate + estradiol implants, and monensin in the feed) or soybean meal. Dietary treatments in the finishing phase were deve...
متن کاملEffects of Source and Level of Ruminally Protected Choline on Performance and Carcass Characteristics of Finishing Beef Steers
Previous research (Galyean et al., 1997) indicated that daily gain and feed efficiency were improved when finishing beef steers were fed graded levels of ruminally protected choline (RPC; .25, .5, and 1% of dietary DM). Responses were cubic (P < .10) in nature, with an 11% increase in daily gain and a 6.8% improvement in feed efficiency for .25% RPC vs the control diet, but no effect on gain or...
