    Summary
    This summary is machine-generated.

    Calf suckling behavior in beef cattle shows distinct daily patterns, with activity peaking in the morning and evening. Heavier calves and higher-producing cows suckled less frequently.

    Area of Science:

    • Animal Science
    • Behavioral Ecology
    • Veterinary Medicine

    Background:

    • Understanding suckling behavior is crucial for assessing calf welfare and dam-calf bonding.
    • Previous research has identified diurnal patterns in suckling, but specific influences require further investigation.

    Purpose of the Study:

    • To quantify suckling incidence and duration in beef calves.
    • To identify peak suckling times and factors influencing suckling frequency and duration.

    Main Methods:

    • Eight 24-hour observation periods were conducted in a herd of Polled Hereford and Simmental cows.
    • Suckling events and duration were recorded, with data analyzed for influences of time of day, estrous cycle, milk yield, calf weight, age, breed, and sex.

    Main Results:

    Related Experiment Videos

    • Average suckling events per calf were 5.0 +/- 0.1, with an average duration of 46 +/- 1 minute per 24 hours.
    • Suckling activity peaked from 0500-0700, 1000-1300, and 1700-2100 hours.
    • Higher milk yield and heavier calf weight were associated with decreased suckling frequency (P < 0.01).

    Conclusions:

    • Calf suckling exhibits significant diurnal patterns, with specific peaks in morning and evening.
    • Individual calf and dam characteristics, such as calf weight and milk production, influence suckling frequency.
    • Estrous cycle, calf age, breed, and sex did not significantly affect suckling behavior.
