This experiment examined the effects of a synbiotic supplement (yeast-derived prebiotic + Bacillus subtilis probiotic), which replaced or was fed with feed-grade antimicrobials (monensin and tylosin), on performance and health responses of feedlot ca

The constantly growing size of the national beef cattle evaluations datasets creates computational challenges to estimate breeding values and their accuracies under the single-step methodology timely and in a robust way. This study aims to present st

The use of probiotics in swine production may be an alternative to antibiotics for both disease prevention and growth promotion. Limited data exist on their potential to modulate offspring immune function when fed solely to the dam. A study was desig

Two studies were conducted to estimate the SID Lys requirement for growth and feed efficiency of 35-80-kg DNA finishing pigs. In Exp. 1, 608 pigs (600 × 241, DNA; initially 36.3±0.91kg) were used to estimate the SID Lys requirement from 35-55-kg. I

When interseeded into bermudagrass (Cynodon dactylon), alfalfa (Medicago sativa) has shown to increase herbage accumulation and improve forage nutritive value in Southern forage systems. However, data is limited on biennial red clover (Trifolium prat

A total of 912 pigs (PIC TR4 × (Fast LW × PIC L02)) were used in a 43-d trial to evaluate the influence of feed grade amino acid levels in late nursery and grower diets containing 30% dried distillers grains with solubles (DDGS) on growth performan

Distillers dried grains with solubles (DDGS) has a high concentration of Leu, and the Trp requirement for growing pigs may be increased if diets contain excess Leu. Therefore, the objective of this experiment was to determine the optimum standardized

Warm-season perennial grass, also called C4, are the predominant forages for ruminant production in tropical and subtropical regions. In general, C4 grasses have greater herbage production in warm-climate regions due to a more efficient carbon fixati
