The chemical name of L-lysine is L-2,6-diaminoacetic acid, molecular formula: C5H14N2O2?HCL white crystal. Lysine is often the first or second restricted essential amino acid due to its high nutritional requirements and low levels of feed ingredients. The content of lysine in cereal feed is not high. Although the content of bean feed is high, soy cake or soybean meal as raw material for chicken feed is a by-product of processing. Lysine will reduce activity when it is heated or stored for a long time. Although there are many lysines in animal feed such as fishmeal, there are similar problems of inactivation. Thus, the lysine that can be utilized in the feed is only about 80% of the value obtained by chemical analysis. Antagonism between lysine and arginine is still present in the nutrition of lysine. Lysine is often added to the feed of broiler chickens to make it have a higher content, which tends to reduce the utilization of arginine, so it is necessary to supplement arginine at the same time.
Insulating glass units, or IGUs, are designed to keep homes warmer in the winter and cooler in the summer. consists of twoor more glass window panes separated by a vacuum or gas-filled space to reduce heat transfer across a part of the building envelope. A wide variety of colored Insulated Glass options are available to you. Colored Insulated glass can be reached through Colored pvb Laminated Glass, colored tinted glass, reflective glass, low-e glass with color itself, sometimes, printed with some design also can match.
