Performance Responses and Fillet Quality of Rainbow Trout () to Increasing Addition Levels of Dietary Supplementation of Guanidinoacetic Acid.

Guanidinoacetic acid (GAA) plays an important role in cellular energy use and protein synthesis. The objectives of this study were to determine the optimal level of dietary GAA regarding the growth performance and fillet characteristics of rainbow trout (). A total of 300 trout (initial weight, 66.

The effect of lysine intake on energy partitioning and utilization in growing pigs.

An experiment utilizing 12 castrated male pigs within a body weight range of 23 - 147 kg was conducted to ascertain whether the alteration of protein quality by varying the level of lysine intake is influencing total energy retention, heat production and therewith efficiency of energy utilization for growth. The animals were allotted to two treatments of a constant medium (11.5 g/d) or high lysine intake (13.
