Understanding Heat Stress

a) Causes of Heat Stress

Heat stress occurs when an animal’s heat load exceeds its heat dissipation capacity. The major contributing factors include:

High environmental temperatures: Extreme heat, especially above 30°C (86°F), increases heat accumulation in animals.

High humidity: When humidity levels exceed 60%, animals struggle to cool down through sweating or panting.

Poor ventilation: Limited air circulation in housing facilities worsens heat stress.

Direct solar radiation: Exposure to direct sunlight increases heat absorption.

High stocking density: Overcrowding reduces air movement and increases heat production.

Inadequate water supply: Dehydration exacerbates heat stress.

Metabolic heat production: High-energy diets increase body temperature during digestion.

b) How Animals Regulate Heat

Livestock and poultry use various mechanisms to regulate body temperature:

Evaporative cooling: Sweating in cattle and panting in poultry and pigs help release excess heat.

Vasodilation: Expansion of blood vessels helps dissipate heat.

Behavioral adaptation: Seeking shade, reducing feed intake, and increasing water consumption.

When these mechanisms fail, animals experience heat stress, leading to health complications.

 

Effects of Heat Stress on Poultry and Livestock

Artificial insemination plays a crucial role in modern animal production by offering several benefits, including:

Genetic Improvement: AI enables the use of high-quality semen from superior male animals, improving offspring traits such as milk yield, growth rate, and disease resistance.

Disease Control: Since AI eliminates direct mating, it reduces the spread of sexually transmitted diseases.

Cost-Effectiveness: AI reduces the need for maintaining multiple breeding males, thus lowering feeding and management costs.

Better Fertility Management: Farmers can control and optimize breeding seasons to enhance reproductive efficiency.

Increased Productivity: AI allows selective breeding, which improves overall herd or flock performance.

Methods of Artificial Insemination

The AI procedure varies depending on the species. The key methods used in livestock and poultry are:

a) Artificial Insemination in Cattle

Semen Collection: Semen is collected from high-quality bulls using an artificial vagina or electroejaculation.

Semen Processing: Semen is analyzed for viability, diluted with extenders, and stored in liquid nitrogen (-196°C) for future use.

Insemination Process: A trained technician inserts the semen into the uterus using an AI gun.

Timing: AI is performed during estrus (heat period) for maximum conception rates.

 

b) Artificial Insemination in Sheep and Goats

Semen Collection: Fresh or frozen semen is used.

Insemination Techniques: Vaginal, cervical, or laparoscopic AI methods are used depending on the breed and semen quality.

Synchronization: Hormonal treatments are often used to synchronize estrus cycles for timed insemination.
