[Ruminants as breeding animals (author's transl)]

R A Prins

    Tijdschrift Voor Diergeneeskunde
    |February 15, 1981
    PubMed
    Summary

    Ruminants upgrade low-quality feed into valuable products. Breeding cattle for larger rumens and higher salivation will improve roughage digestion for future needs.

    Area of Science:

    • Animal Science
    • Nutritional Biochemistry
    • Ruminant Physiology

    Context:

    • Ruminants convert low-nitrogen, high-structural carbohydrate feeds into valuable products like milk and meat.
    • Agricultural wastes and low-value feeds are transformed by ruminants, benefiting monogastric animals.
    • Overfeeding concentrates leads to metabolic disorders and underutilization of ruminants' digestive capabilities.

    Purpose:

    • To highlight the unique digestive capabilities of ruminants.
    • To address the challenges of modern feeding practices in ruminants.
    • To propose criteria for breeding future cattle breeds.

    Summary:

    • Ruminants are efficient up-graders of poor-quality feedstuffs, converting them into essential animal products.
    • Current feeding practices often involve excessive concentrates, leading to suboptimal production and health issues.
    • Future breeding strategies should prioritize large ruminal volume and high salivation rates for enhanced roughage utilization.

    Impact:

    • Improved understanding of ruminant digestive physiology.
    • Potential for more sustainable livestock production systems.
    • Guidance for breeding programs to enhance feed efficiency and reduce metabolic disorders.
