Tissue Gain The separation of energy retained (gain, lactation, fetal development) from maintenance is artificial; maintenance and energy retention are highly integrated. Tissue gain should be considered as the net result of synthesis and degradation (turnover) rather than as simple accretion of body water, protein, fat and minerals. Tissue turnover accounts for a great deal of energy required by the animal. This takes away from energy efficiency and energy that could go to gain. Utilization of ME

Tissue Gain Normal pattern of growth influences the efficiency of utilization of ME for tissue energy gain. Utilization of ME Normal Pattern of Growth The efficiency of utilization of ME above maintenance for tissue energy gain is influenced by maturity and diet composition. As the animal ages, a greater portion of the gain is composed of fat relative to protein. Based upon the ruminant’s metabolic pathways, the theoretical maximum efficiency for growth is approximately 80%. Actual efficiency is less (especially for protein) due to tissue turnover and energy required for metabolic cycles such as ion transport.
