Calf growth

Growth rates between March and September were calculated each year (1987-1997) by linear regression of body weight on age in months for all calves less than 24 months of age on 1st March and for which at least 4 weights were recorded. Calves born later during March or April of the same year were also included.

The period from March to September was chosen because growth rate had been shown to be approximately linear during the wet season. Growth during the remainder of the year was more unpredictable and hence was not calculated.

The results are stored in CS10Data3 and documented in CS10Doc3.
