Generalities in breeding


Livestock have a “comfort” temperature

The comfort temperature is the zone of thermal neutrality. Outside this zone, the animal expends energy to keep its body temperature stable. As a result, there is a decrease in production.

In addition, heat stress also leads to a decrease in immunity, making animals more sensitive to external aggression. In some cases, thermoregulation can also lead to behavioural changes. For example, an increase in breathing rate, agitated animals, etc. Heat stress therefore affects the reproduction of both males and females with a decrease in fertility.

Furthermore, animals recover slowly. For long-cycle animals such as ruminants, performance can decline several months after the hot period. For breeding animals, heat stress leads to increased sensitivity of the offspring: birth weight, immunity.

In conclusion, to support animals during this period, the CCPA Group innovates with natural nutritional solutions that act on the causes and consequences of heat stress.

Incorporating complex and synergistic formulas, the only ones able to act on these different levels, the products are specific to each species. The effects are quickly visible.

Overview of the consequences of heat stress in animals

Figure 1. Consequences of heat stress in animals
  • Influence of heat stress not on the animal itself but on “its descendants
  • Originally ruminants, here multi-species.
  • Specific organs (udders… pododermatites)

Between now and 2025, +25% days heat stress !

Figure 2. Time evolution of France mean temperature anomalies in summer relative to the 1976–2005 climatology simulated by the EURO-CORDEX models (historical simulations: grey, RCP4.5: green, RCP8.5: red). Solid lines give the median, shading and dashed lines give the envelope defined by the [25–75%] model range for each scenario. Time series are smoothed with a polynomial regression.
