A weaned piglets, intestinal broad reshaping occurs to shift to adapt to solid feed from the liquid feed. The stage adaptation of nutritionists constitute a significant challenge, they must consider how to help the transition to solid feed pigs, but also to meet the expected costs.
From the perspective of an amino acid, reduce intestinal pressure while reducing the cost of the diet is an important strategy is an amino acid added to reduce rations by reasonable crystalline crude protein content. Reducing the crude protein content reduces the amount of the large intestine can ferment proteins, which would reduce the incidence of post-weaning diarrhea. This will also reduce the demand for protein sources, such as soybean meal, which will constitute the intestinal immune challenges, while also reducing the amount of some expensive protein sources. Early weaned pigs total lysine levels often configured as 1.65 to 1.7% or higher. At low levels of lysine (1.35% standardized ileal digestible (SID) lysine or 1.5% of total lysine) can reduce the need for expensive protein sources, but on pig performance is small.
When the low-lysine diets SID when other amino acids relative to lysine ratio is very critical. Other amino acids relative to the proportion of lysine, methionine plus cysteine was 58%, 62% threonine, valine 65%, isoleucine 52% (if the blood product usage is high, then the percentage should be 60%). Tryptophan ratio of lysine remains controversial, recommended ratio is between 16.5 to 20 percent, depending on the level of nutrients as well as the specific experiment. A particular amino acid (e.g. arginine or glycine, and glutamic acid) seem to be able to meet the needs of the non-essential amino acids, and for the development of the intestinal tract has the intended effect.
