Extract

In order for producers to meet market requirements for lamb carcasses from the resources available, they need to know how breeds differ in growth and development over time and how this is affected by feeding regime. A previous paper explored the effect of diverse breed and feed types on carcass composition, growth and feed intake. This paper uses different mathematical descriptions of growth to study the relationships between live weight and time and between live weight and cumulative feed intake.
