Since there is enough genetic variability in these traits, improvement of growth capacity on pasture can be achieved by selection as shown by New Zealand results.

The microprocessor analysis differentiates between jaw movements devoted to prehension and mastication during eating, ruminating and idling, and summates both the jaw movements and time devoted to each action. Preliminary observations suggest that the ratio of time dev

Among the possibilities to restore these areas to agriculture, the re-introduction of suckler herds of beef cattle could be of interest. This production system could be advantageous because of the availability of low cost grazing land but most Italian farm

Summer Grazing and Winter Feeding Studies with Suckler Cows the high stocking rate had lowest daily gains in all three years. Prior to early August, stocking rate had no effect on calf performance except in year 2 when those at the high stocking rate had lower daily gains. From early August until the end of the grazing season stocking rate significantly aff
