    Area of Science:

    • Animal Science
    • Dairy Cattle Health
    • Mastitis Management

    Background:

    • Somatic cell count (SCC) is a key indicator of bovine udder infection and milk quality.
    • Mastitis significantly impacts dairy cow productivity, leading to substantial economic losses.
    • Quantifying milk yield loss due to mastitis is crucial for herd management.

    Purpose of the Study:

    • To develop a programmable calculator program for assessing milk yield loss in dairy cows.
    • To estimate economic losses associated with mastitis based on linear somatic cell count scores.
    • To project optimal milk production and herd composition for improved mastitis control.

    Main Methods:

    • Utilized linear somatic cell count scores to calculate milk yield loss.
    • Developed a program to display herd distribution by lactation number and linear score.
    • Quantified yield loss in pounds and dollars per cow and for the entire herd.

    Main Results:

    • The program calculates milk loss in pounds and dollars, providing cow-specific and herd-level economic impacts.
    • It visualizes herd distribution against present and optimal mastitis control scenarios.
    • Estimates were made for optimal milk production and the reduction in cow numbers needed to achieve mastitis goals.

    Conclusions:

    • The developed program offers a valuable tool for dairy farmers to quantify and manage mastitis-related economic losses.
    • It aids in setting achievable production goals and understanding the herd's current status regarding mastitis.
    • Implementing the program's insights can lead to improved herd health and financial outcomes.
