Lab Analysis Results

Pasture Analysis

Pasture samples were taken to gain insight into the variation in feed quality attributes and mineral content, which it must be remembered are a snapshot at a point time, since these values will change through the year. Recall also, the samples were taken to be representative of how the intended livestock would graze, not a full pasture cut from ground up.

Plant energy reflects the combination of soil nutrition, grazing and species desirability.

Crude Protein%

11.3

15.2

9.0

> 15

Low protein (<18%) suggests legume component can be improved and quality is below optimal

Digestibility (DMD) (%)

> 60

Below 55% will likely reduce animal performance (ADG), above 60% is good quality feed

Neutral Detergent Fibre% (NDF)

<50

Higher plant fibre reduces total animal intake and associated performance, below 60 preferred

⁠

Plant Phosphorus is a good indicator of feed value, as it is strongly linked to plant metabolisable Energy, which directly impacts animal performance, ie ADG

⁠

The sample with good P levels was Bull Pdk, which was a high quality feed

⁠

All 3 samples show lower than desired metabolisable energy (ME) in the forage
