Improving Growth on Excess Protein Pasture – Sheep

Supplementing grains to livestock grazing pastures high in protein manages the excess ammonia in the rumen and prevents energy wastage leading to lower production.

Compare managing excess pasture protein with supplementary feeding to providing no additional supplement.

When there is high quality and fast growing pastures, the maximum number of sheep per feeder is 250.
Growing out weaned sheep for 60 days post weaning on high quality pastures can be common.
150g / day is a common ration to manage the excess protein.

Managing High-Protein Pastures to Boost Growth Rates

Excess Protein Sheep Information Sheet

Many pastures are very high in protein during their elongation phase, which is when they are often used to grow and finish young stock. Weaned lambs typically require 14–16% protein in their diet, while pastures can contain 25–35%.

Excess protein must be processed by the lamb’s rumen and excreted via urine, a phenomenon known as “the protein cost.” It’s estimated that each extra 1% of protein excreted costs 0.15 MJ of energy.

Supplementing high-quality pasture with starch helps manage excess protein in the rumen, allowing stock to grow faster and increasing kilograms produced per unit of grass. Research shows that supplementing high-performing pastures with 100 g/day of wheat can increase live weight gain by more than 50 g/day.

Our information sheet provides a brief overview and explains:

  • How pasture composition can limit production.
  • The latest science on correcting pasture-related issues.
  • How to quantify potential gains from complementary feeding.

Additional Considerations Improving Growth on Excess Protein Pasture – Sheep

Farming operations are complex, and the following factors are not included in this calculator:

  • Multi-purpose feeder use: Feeders can be used for other purposes throughout the year, lowering depreciation costs and increasing return on investment.
  • Improved pasture utilisation: Supplementing pasture can slow feed passage and improve utilisation, producing more from the same amount of grass.
  • Enhanced growth and reproduction: Higher growth rates during this period lead to higher weights at joining and improved ewe lamb conception rates.
