When measuring body condition, proportions, weight and growth in relation to age, it is possible to set up a weight–age and size–age chart for a number of rabbits and monitor them over a period of 10 weeks. Use a pre-weighed container of appropriate size and a triple beam balance or a bucket balance to determine the weight. A measuring tape can be used to determine overall length, girth, body proportions and size of skull. When measuring a rabbit’s dimensions, care should be taken not to exert too much pressure on the trunk, particularly of pregnant females.
