What distinguishes first-last rotational grazing?

1. Dividing fields into smaller paddocks

2. Using one group of cattle only

3. Grouping cattle based on age and body condition score

4. Utilizing multiple types of forage simultaneously

The correct answer is: Grouping cattle based on age and body condition score

In first-last rotational grazing, the key feature lies in the strategic grouping of livestock based on physiological and nutritional needs, such as age and body condition score. This method allows for more effective management of pasture resources and ensures that each group of cattle receives the optimal forage necessary for their development, health, and productivity. By placing younger or less conditioned animals in the 'first' rotation, they can graze on higher-quality forage before it becomes overgrazed, promoting better weight gain and overall health. This approach contrasts with other grazing methods that might focus solely on dividing land into smaller sections, managing a single group, or utilizing various forage types. While those strategies may have benefits, they do not address the specific needs of different animal groups at different growth stages, which is vital for maximizing both pasture and animal productivity in rotational grazing systems.
