[Growth studies of fattening hybrid heifers. 3. Studies of the total retention of fattening hybrid heifers under different energy supply].
These investigations show that daily retention in the course of growth is subject to dynamic changes specific for each nutrient. While there are only insignificant differences between daily live weight growth as the practically usable parameter and body weight growth, daily dry matter deposition takes a comparatively different development. The specific development of dry matter deposition depends on the daily retention of protein and fat. Whereas in early age protein retention is higher, fat retention increases in the course of live weight development in dependence on the energy level. Different energy supply results in distinctly differentiated protein, fat and energy retention per day. The highest variation in daily retention could be ascertained for fat retention in dependence on energy supply. A comparison of the cumulated experimental results with model values generalised from the growth function corresponded well.
