Effects of Barley Cultivar and Growing Environment on Feedlot Performance and Carcass Characteristics of Finishing Beef Cattle: Author: McDonnell, Michael F.; Date: 2004-08-15; Program: Animal and Range Sciences; Abstract: Thirty-two crossbreed beef heifers (initial weight 349 kg ± 2.21 kg) were individually fed finishing diets for 84 d in a 2 X 2 factorial experiment examining the effects of barley cultivar (Harrington vs. Valier) and growing environment (irrigated vs. dryland) on animal performance, carcass characteristics, and nutrient digestibility. No differences in ADG (P = 0.46; average 1.78 kg/d) or final weight (P = 0.23; average 498 kg) were detected due to cultivar. Barley cultivar did not affect DMI (P = 0.80; average 9.8 kg/d), or feed efficiency (P = 0.63; average 18.3 kg gain/100 kg ...; Download File | View full details

Variation in Supplement Intake by Grazing Beef Cows: Author: Kincheloe, Janna Jo; Date: 2004-05-15; Program: Animal and Range Sciences; Abstract: One hundred twenty-one pregnant Angus cross cows (3 to 9 years of age; avG. wt 636 kg ± 50 kg) grazing native range pastures (Agropyron spicatum, Festuca idahoensis) were used to determine effect of herd size and cow age on individual supplement intake of a hand-fed pelleted protein supplement, variation in supplement intake, individual forage intake, and performance. The study was conducted at the Montana State University Red Bluff Research Ranch near Norris, MT from October 14, 2002 to December 13, 2002. Treatment was herd size, with seventy-six cows assigned to a large herd an...; Download File | View full details

Is there a Genetic Basis for Forage Quality of Barley for Beef Cattle?: Author: Surber, Lisa Marie McKinley; Date: 2006-08-15; Program: Animal and Range Sciences; Abstract: Despite the importance of forage quality to animal performance, barley forage quality has not been used as a selection criterion in barley breeding programs. Our objectives were to: (1) evaluate Steptoe x Morex doubled haploid (DH) and Lewis and Karl recombinant inbred line (RIL) populations for forage quality characteristics; (2) identify QTL for forage quality characteristics; and (3) determine if variation in forage quality characteristics among barley lines is heritable. The 145 DH lines were grown in in 1999 and 2001 under irrigated conditions in Bozeman, MT while 146 RIL lines were grown...; Download File | View full details

Training responses of two-year-old Quarter horses fed rapidly fermentable carbohydrates: Author: Black, Wade Raymond; Date: 2009-05-15; Program: Animal and Range Sciences; Abstract: Two replicated experiments (ExP. 1: May 14 to June 8; ExP.2: June 25 to July 20) evaluated effects of feeding grain to 2-yr-old Quarter horses on behavior and physiological parameters during early stages of traininG. In each experiment, 6 different horses were allotted by sex and weight to 2 diets; hay only or hay plus 2.3 kg/d grain. Horses were group-housed with ad libitum access to grass/alfalfa hay and water, and were individually fed 1.15 kg grain or 40 g salt (placebo) at 0800 and 1600 for 7 d prior to and during traininG. The trainer was blind to diet assignments. Horses were trained 5 ...; Download File | View full details
