Machine Learning and Statistical Models for Genomic Selection of Phytophthora Fruit Rot Resistance in Watermelon

Breeding for Phytophthora fruit rot (PFR) resistance caused by the devastating pathogen Phytophthora capsici remains challenging in watermelon mainly due to phenotyping constraints. To overcome these bottlenecks, we developed and validated genomic selection models using an inters...

44. A Benchmark Study of Feeding and Management Practices, Feed Utilization, and Adoption of Growth-enhancing Technologies by the Canadian Feedlot Industry.

Abstract The Canadian feedlot industry is exceptionally diverse, in both operational practices and feeding management. Previous Canadian feedlot industry surveys lacked detailed information on feed ingredient usage, feeding management, and the use of growth and health enhancing t...

331. Growth Performance of Backgrounding Steers Fed a Diet with Continuous or Intermittent Inclusion of Ergot Alkaloids with and Without a Mycotoxin Deactivating Product.

Abstract This study evaluated the effect of feeding a backgrounding diet (60% barley silage:40% concentrate; DM basis) containing ergot alkaloids, with and without a mycotoxin-deactivating product (MDP), on the growth performance of feedlot steers. Crossbred steers (n = 360; 330...

324. Behavioral Responses of Impaired Feedlot Cattle After Chronic Pen Entry and Associations with Time to Death.

Abstract In feedlots, chronically impaired cattle are often moved to specialized pens, where they have easier access to resources and to facilitate monitoring and care. Understanding how chronic cattle transition into this new environment may provide insights into their likelihoo...

Perennial and annual cropping sequences differentially influence soil functionality in Luvisolic soils

<title>Abstract</title> Cropping system diversification with perennial herbage seed crops has been proposed as a promising strategy for sustaining soil health and functional agroecosystems. We evaluated the impact of diversified cropping systems on key soil properties important f...
