“…In addition, a reduction in ruminal pH values is expected with an increase in collection time after supplementation, due to the rapid fermentation of carbohydrates in the rumen and decreased salivation due to the shorter rumination time, resulting in a drop in pH [41]. This decrease in pH may also be associated with the peak concentration of ammonia in the rumen after feeding, as the reduced pH reduces the absorption of ammonia by the rumen and decreases microbial growth [42]. It is worth mentioning that the average ruminal pH values in this study were not reduced to below 6.2, both due to the treatment types and the collection times after supplementation, which may have favored the growth of cellulolytic bacteria [40] and thus contributed to fiber digestion.…”

Two experiments were conducted to evaluate the effect of replacing cottonseed meal with DDG on ruminal parameters, methane (CH4) emissions (Experiment 1), and animal performance (Experiment 2) of young Nellore bulls grazing Marandu grass during the rainy season. Four supplementation strategies were used in both experiments: (1) Mineral supplementation (MS); (2) conventional multiple supplement (energy/protein) with cottonseed meal and citrus pulp (CMS); (3) CMS with 50% cottonseed meal replaced by DDG (50DDG); and (4) CMS with 100% cottonseed meal replaced by DDG (100DDG). The 50DDG condition resulted in greater intake of dry matter (p = 0.033), organic matter (OM) (p = 0.050), forage (p = 0.035), and digestible OM (p = 0.031) than 100DDG. The supplemented animals presented greater final body weight (BW) and average daily gain than the animals consuming MS (p = 0.011), and lower pH, acetate, and acetate:propionate (p < 0.05). However, the treatments had no influence on stocking rate, gain per area, and enteric CH4 emissions (p > 0.05). Replacing cottonseed meal with DDG does not result in great variations in ruminal parameters, animal performance, and enteric CH4 emissions of grazing Nellore cattle during the rearing phase in the wet season. Both protein sources in 0.3% BW supplementation can be used to intensify beef cattle production in pastures.
