Effect of processing soybeans on their use by calves

D A Prasad, J L Morrill

    Journal of Dairy Science
    |February 1, 1976
    PubMed
    Summary

    Roasting full-fat soybeans improved nitrogen retention in Holstein calves compared to raw or microwaved soybeans. This suggests roasting enhances soybean protein utilization for young cattle.

    Area of Science:

    • Animal Nutrition
    • Agricultural Science
    • Food Science

    Background:

    • Soybean protein is a vital nutrient in animal feed.
    • Processing methods can significantly alter soybean protein quality and digestibility.
    • Understanding optimal processing for Holstein calves is crucial for efficient livestock production.

    Purpose of the Study:

    • To evaluate the impact of different processing methods (grinding, roasting, microwave heating) on the nutritional quality of full-fat soybeans.
    • To assess the effects of these processed soybeans on nitrogen retention and nutrient digestibility in Holstein calves.

    Main Methods:

    • Full-fat soybeans were processed via grinding, roasting, or microwave heating.
    • Rations containing these processed soybeans were fed to Holstein calves.
    • Nitrogen digestibility, nitrogen retention, and the digestibility of dry matter, ether extract, crude fiber, and nitrogen-free extract were measured.

    Main Results:

    • Nitrogen digestibilities were similar across all rations.
    • Nitrogen retention was significantly higher for roasted soybeans compared to raw or microwaved soybeans.
    • Protein hydrolysis was higher in roasted soybeans, correlating with lower nitrogen solubility.
    • Digestibility of dry matter, ether extract, and nitrogen-free extract showed no significant differences.
    • Crude fiber digestibility was lower in the roasted soybean ration.

    Conclusions:

    • Roasting enhances the protein quality of full-fat soybeans for Holstein calves, leading to improved nitrogen retention.
    • The observed increase in protein hydrolysis and decrease in nitrogen solubility in roasted soybeans likely contribute to better nitrogen utilization.
    • While crude fiber digestibility was reduced, the overall benefits to protein utilization suggest roasting is a favorable processing method for soybean-based calf rations.
