The post-weaning period is a critical time in the pig’s life with both short- and long-term consequences for both productivity and health. Nutrition plays a vital role in this transition…
…of DL‐methionine indicated that a dietary methionine + cysteine level of 15.7 and 12.5 g kg/diet (as fed) was required to reach 95% of maximum weight and protein gain. The…
…methionine to maintain bird growth and productive performance up to current industry standards given the recent restrictions that have been placed on synthetic methionine. Without synthetic amino acids, methionine requirements…
…(Oreochromis niloticus) to determine the effect of replacing fishmeal with soybean meal and methionine on growth, nutrient utilization, hematology, and plasma biochemistry. Four experimental diets (40% crude protein) were formulated,…
…replacements. Each soy protein source was replicated in diets with and without supplemental lysine + methionine. BP diets consistently performed better than SPC diets. Extrusion pretreatment led to improved consumption…
…control diet contained 40% fish meal, and 20%, 40%, 60% and 80% of the fish meal were replaced with SBM, supplied with 0.3% DL-methionine and 0.2%. In trial II, 60%…
