Suspicion of energetic overfeeding (>= 201 days)

This post is also available on: German

Definition/Causes

Formation of body energy reserves (fat accumulation) in the last third of lactation as a conditional preparation for subsequent lactation is a normal part of the live mass-energy cycle of the dairy cow. If the optimal fat accumulation is exceeded, obesity occurs with negative effects.
Extremely increasing or very high protein content in this lactation period indicates the risk of fatty degeneration.
If there is an insufficient proportion of structure in the ration, acidotic loads are to be expected.
Due to fatty degeneration, problems with calving as well as performance reductions, metabolic diseases and fertility disorders are inevitable in the subsequent lactation.

Signal values: increase in E% 0.6% > compared to the lactation period 101.-200. Day
or P% > 4.1

red

>= 30 % in the lactation section

yellow

>= 15 to < 30 % in the lactation section

Measures

Goal: Align energy intake with demand – reduce it – to avoid further fatty degeneration!

Check feed intake

  • is the feed ration (calculated) also eaten?
  • Can the animals select high-energy components?

Check feed quality

  • Roughage digestibility above 70%.
  • Secure 400 g of crude fibre for every 100 kg of body mass.
    • Pay attention to the proportion of structurally effective crude fiber.
    • 8 – 10% of the particles should be larger than 4 cm.
  • Feed without impurities and deteriorations (dirty, moldy, frozen)
  • Check on-demand feeding for function and calibration

Check feed ration

  • Ration calculation and ration control
  • Ensuring structure and versatility
  • Assignment to feeding groups
  • Adapting concentrate quantities to milk yield

Controlling animal health

Perform a body condition assessment (BCS). Animals can also gain body mass during dry periods
