• Condition optimization – avoiding both excessive weight gain and under-conditioning.
• Nutritional adjustments – gradually increasing energy and protein supply to meet the rising demands of the developing fetuses and prepare the udder for milk production.
• Health monitoring – any potentially stressful procedures, such as hoof trimming, vaccinations, or pen cleaning, should be completed no later than six weeks before the expected kidding date.

This preparation directly influences the start of lactation, with well-managed goats showing higher milk peaks, better fertility, and improved longevity in the herd.

Heat Stress as a Compounding Factor
When the transition period coincides with periods of high summer temperatures, heat stress can become a significant challenge. Dairy goats are sensitive to elevated temperatures, and prolonged heat stress negatively impacts feed intake, rumen efficiency, and overall metabolic function. In late gestation, heat stress can reduce fetal growth, impair immune function, and increase the risk of kidding complications.

Physiological signs of heat stress include increased respiration rate, reduced activity, and a decline in dry matter intake. Even short-term drops in feed intake can lead to energy deficits, which are particularly harmful during the critical transition phase.

Mitigation Strategies
To minimize the impact of heat stress during this period, farmers can focus on:

• Cooling systems – using fans, sprinklers, or misting systems to lower barn temperatures.
• Ventilation improvements – ensuring continuous air exchange, especially in enclosed housing.
• Feeding strategies – offering fresh feed during cooler hours of the day and formulating rations with highly digestible ingredients to maintain energy supply despite reduced intake.
• Access to shade and clean water – providing multiple water points and shaded areas in outdoor systems.

By combining proactive transition management with effective heat stress mitigation, farmers can safeguard the health and performance of their dairy goats, ensuring a smooth start to the fall kidding season and optimizing production potential.
