Genetics and Mapping of Quantitative Trait Loci of Feed Quality-Related Traits in Barley (Hordeum vulgare L.): Author: Abdel-Haleem, Hussein Ahmed; Date: 2005-05-15; Program: Plant Sciences; Abstract: The agricultural sector continues to outpace other industries in Montana. Cattle and calf production are 50% of Montana's agricultural cash receipts. Based on its moderate protein content and lower price, barley is an alternative to corn in finishing cattle diets. Most of Montana barley is produced for animal feed. The objective of this project is to encourage calf producers to retain more feeder calves in Montana by developing improved value feed barley for both the barley grower and cattle producers. Barley has been criticized for cattle feed because of its rapid digestion in the rumen, whic...; Download File | View full details

Genetic Routes to Modulate Rate of Dry-Matter Disappearance of Barley Grain in the Rumen of Cattle: Author: Jewell, Jeremy Burke; Date: 2007-05-15; Program: Plant Sciences; Abstract: Recent research has identified important characteristics of barley grain as feed for cattle. Of these, low ruminal dry-matter digestibility (DMD) is of particular importance as it is highly correlated with animal performance and with animal health. This research attempts to identify genetic loci that contribute to the ruminal DMD of barley grain. The utility of the barley ant18 mutation for decreasing ruminal DMD was investigated. The DMD of several barley cultivars and their ant18 mutations was investigated in a randomized complete block design in two environments. Genotype by environment int...; Download File | View full details
