Libido and mating behavior in bulls, boars and rams. A review

Area of Science:

• Animal Science
• Reproductive Biology
• Behavioral Ecology

Background:

• Libido and mating ability are significant traits affecting production in livestock.
• These traits are heritable, variable, and measurable in food and fiber producing animals.
• Male rearing conditions can impact sexual behavior expression.

Purpose of the Study:

• To review literature on libido and mating behavior in bulls, boars, and rams.
• To highlight the importance of these traits for animal production.
• To discuss factors influencing mating behavior and reproductive performance.

Main Methods:

• Restricted literature review focusing on bulls, boars, and rams.
• Analysis of genetic, environmental, and social influences on mating behavior.
• Examination of male sexual response cues and female receptivity.

Main Results:

• Females primarily initiate sexual interactions.
• Visual cues are more critical than olfactory cues for male sexual response.
• Estrus status and social interactions among males significantly affect mating behavior and reproductive outcomes.

Conclusions:

• Assessing male libido and mating ability is vital for optimizing livestock production.
• Understanding social dynamics in multi-sire groups is essential for reproductive efficiency.
• Proper sire evaluation reduces risks associated with single-sire breeding programs.
