Model for Lamb Production

Background

Raising lambs intensively in feedlots is becoming common in SA. As margins in intensive feeding systems are low, accurate growth curve data is important.

Aim of the project

The aim of this project is to develop a prediction model that can be applied to the growth and feedlot production characteristics of various South African sheep breeds.

Objectives of the project

To collect growth data and determine the growth curves of each breed and then to model the curves with nonlinear regressions.
To develop feed intake curves for each breed with the change in live weight.
To develop curves for the increase in backfat thickness, which is measured using ultrasound technology.
To develop curves to describe wool growth of the growing lambs of various wool breeds.
To determine the ideal slaughter weight of lambs from different breeds.
To assess the product quality of the wool, leather and meat obtained from the various breeds.
To develop curves to predict growth, intake, fat deposition and slaughter weight of crossbred lambs.
