Track 2-1-1: Grazing Systems, Grassland Restoration and Livestock Production
Description
When animals are kept under feed restriction for a certain period of time followed by availability of feed again had high growth rate and even exceeded those of animals that were well fed throughout the same period (Tolla et al., 2003), because of physiological impulse called compensatory gain. Thus it improves feed efficiency and reduces feeding cost (Neto et al., 2011). However, when this happens in females growing calves it is desirable, provided it does not occur during puberty so that there is no reproductive damage. But compensatory growth varies depending upon the intensity and duration of under nutrition before re-alimentation. In the present study the effects of moderate level of feed restriction and later re-alimentation with strategic supplementation approach (a mixture of protein and energy sources) on nutritional status and growth performances were recorded in female growing calves.
