Book Description
Eight Angus cross-bred cows (669 ± 23.2 kg of BW) fitted with duodenal and ruminal cannulas grazing winter wheat pasture (WWP) were used in a split-plot design to evaluate the effects of monensin supplementation and WWP stage of maturity on forage intake, digestive function, metabolizable protein, and ruminal fermentation. Supplemental treatment was the main plot, and stage of maturity was the subplot. Two levels of monensin supplementation: 1) Control (CON; 1.0 kgcow−1d−1 of wheat middling only), and 2) monensin (MON; CON plus 200 mg of monensin); and two stages of WWP maturity: 2) mid-March (MAR; March 13 to March 26; vegetative stage), and 2) early April) (APR; March 27 to April 8; heading stage) of 2017 were compared in a 2 x 2 factorial arrangement of treatments. Cows grazed in a single wheat pasture with supplements deposited directly into their rumens through their rumen cannula at 0700 daily. Monensin supplementation did not affect forage intake (P = 0.64), nutrient flow to duodenum (P ≥ 0.47) or total tract digestion expressed as kg/d (P > 0.45). Although, OM and CP flowing to the duodenum were not affected by monensin supplementation (P ≥ 0.53), microbial OM and microbial CP decreased (P = 0.03) with monensin supplementation. As stage of maturity of WWP advanced, forage intake (P = 0.02), ruminal digestibility of DM and OM (P ≤ 0.05) and total tract digestion expressed as kg/d (P = 0.01) decreased. Also, total duodenal CP (P = 0.01), microbial protein (P = 0.01), and feed protein (bypass protein; P = 0.03) flow decreased with advancing WWP stage of maturity. Monensin supplementation increased (P = 0.01) propionate (18.38, and 20.79 ± 0.55 mol/100 mol), and decreased (P = 0.01) the acetate: propionate ratio (3.26, and 2.73 ± 0.13). Ruminal pH (6.03 and 6.31 ± 0.08), acetate (54.6 and 58.3 ± 0.98 mol/100 mol), and acetate propionate ratio (2.52, and 3.48 ± 0.13) increased (P ≤ 0.04), and propionate (21.9, and 17.3 ± 0.56 mol/100 mol) decreased (P ≤ 0.05) with advancing WWP stage of maturity. Results suggest that monensin increases propionate without affecting forage intake, digestibility or metabolizable protein of cattle grazing WWP. Key words: metabolizable protein, microbial synthesis, monensin, winter wheat pasture
