| Bioactivity | DL-Methionine is an essential amino acid containing sulfur with oxidative stress defense effects. DL-Methionine can be used for animal natural feed. DL-Methionine also kills H. rostochiensis on potato plants[1][2][3]. Related Catalog Research Areas >> Infection Research Areas >> Inflammation/Immunology Target H. rostochiensis[1] In Vitro The impact of DL-Methionine supplementation on animal performance interacts strongly with the crude protein (CP) content of the diet. Supplementation of DLM to a 20% crude protein diet for broilers reduces their abdominal fat weight, whereas this is not the case when the diet contained 23% CP. Breast meat yield is increased and abdominal fat content is decreased with increasing DL-Methionine supplementation, and this response is more pronounced in chickens reared on a diet with a lower protein level (20.5% CP) compared with a higher protein level (26%)[2]. In Vivo DL-methionine significantly decreases the numbers of males, females, cysts and eggs of H. rostochiensis on potato plants. DL-methionine kills almost all the nematodes when applied 3 days after inoculation, and DL-methionine does not affect plant growth adversely[1]. References [1]. K. evans, et al.
