Overnutrition induced metabolic dysregulation and partially decreased semen quality in young beef bulls.

ABSTRACT: The objective of this study was to characterize the systemic metabolic response to overnutrition in young bulls and to evaluate the effects of overnutrition on semen characteristics. Half-sibling yearling beef bulls (n = 44) were utilized in a completely randomized design, where bulls were randomly assigned 1 of 2 dietary treatments (n = 4 pens/treatment): 1) Moderate Gain (MG): diet formulated to promote an average daily gain of 1.2 kg/day, or 2) High Gain (HG): diet formulated to promote an average daily gain of 1.8 kg/day. Bulls were housed in a feedlot facility equipped with an automated individual feed intake monitoring system and fed their respective diets for 114 days. Body weight, carcass ultrasonography, and blood samples were collected on days 0, 36, 76, and 114. Blood samples we
