CORN SILAGE VARIETY EFFECT ON YIELD AND MILK PRODUCTION IN DAIRY COWS IN
County Extension Agent
University of Georgia
Corn silage is a major crop utilized to feed 11,000 dairy cows in Brooks County, Georgia. The county ranks second in the state for milk production. Variety trials are essential tools used to assist both dairy and agriculture producers in the selection of varieties that give the highest tonnage and highest pounds of milk per acre. Thirteen varieties where planted in a randomized complete block design with three replications. Plots were harvested and weighed separately. Samples were analyzed at an outside lab for nutritional values and milk production. Twenty-four hybrids were selected with 13 having enough seeds for evaluation. Corn was strip-tilled in ryegrass stubble on April 4th in an irrigated field in Brooks County, Georgia. The eight row plots average one-half acre with three replications per variety. Trial was harvested on August 1st, 2nd and 3rd using a John Deere Chopper. Samples were chemically analyzed at Dairy One Laboratories in Ithaca, NY.
