  • Beef Cattle

    Developing A High-Quality Angus Herd

    Current topics:

    • Improving Efficiency of Artificial Insemination/Estrus Synchronization.
    • Selection Criteria to Reduce Dystocia.
    • Supplementation Techniques to Improve Grazing Efficiency.
    • Understanding How Grazing Behavior and Animal Performance Interact.

  • Food Safety and Meat Science

    Several aspects of food safety and meat science have been or are currently under investigation at the MIR Center. Current research includes formulation trials for lamb summer sausage, meat goat carcass evaluation and retail product development, and microbial evaluations of livestock and wildlife grazing the same pastures.

    Recent publications include:

    • The Use of Ultrasound to Predict Lamb Carcass Yield.
    • The Use of Activated Charcoal to Bind E. coli O157:H7 and Salmonella Typhimurium in Sheep.
    • Relationships Among Weights, Ultrasound and Carcass Characteristics in Boer-Cross Goats.
    • Using Ultrasound to Predict Back-Fat of Lamb Carcasses.
    • Assessment of Microbial Contamination on Deer Carcasses.

    Plant-Herbivore Interactions

    We are currently working to increase use of unwanted plants by livestock while avoiding toxicosis through management solutions, such as feeding compounds in supplements to bind the toxins in poisonous plants and using experiences early in life to increase intake of unwanted plants like redberry juniper and salt cedar.

    Improving Wool and Mohair Production Through Proper Nutrition

    San Angelo is in the heart of the sheep and goat capital of the United States. As a result, research has emphasized improving sheep and goat production for decades.

    Current topics:

    • Effect of Different Protein Sources on Wool and Mohair Production.
    • Inclusion of Yeast to Improve Wool Production on Mineral Intake.
    • Genetics and Nutrition Interact to Affect Wool Characteristics.

    For more information, contact Dr. Mike Salisbury at or 325-942-2027.

  • Sheep and Goats

    Meat Goat Selection and Performance

    In 1995, the Management, Instruction and Research (MIR) Center began a meat goat performance test to help producers select sires with large muscling, limited fat and above-average feed efficiencies. The test is conducted every year.For more information, contact Dr. Mike Salisbury at or 325-942-2027.

    Improving Sheep and Angora Goat Production

    During the past 20 years, improving sheep and goat production on West Texas rangelands has been a primary objective of the MIR Center. That focus continues today as scientists strive to improve lamb weaning weights, fiber quality and marketability of products from the sheep and goat industry.

    Sheep are also included in the livestock the department has for sale every year. For more information, contact Dr. Mike Salisbury at or 325-942-2027.

  • Wildlife

    The deer herd on the ASU Management, Instruction and Research Center has been intensively managed for quality white-tailed bucks for more than 20 years. Our philosophy is based on cost-effective white-tailed deer herd management. This involves manipulating deer density, buck-doe ratios and selective harvesting.

    The property is not high-fenced and we do not feed deer on a year-round basis. We have found that through managing our deer herd population and improving habitat quality, we are able to produce exceptional-quality white-tailed bucks without the cost of high-fencing and intensive feeding.

    We maintain a deer density of one deer for every 15–20 acres and a buck-doe ratio of one buck for every 1.5 does. Brush control, range reseeding and prescribed burning are used on an annual basis to improve habitat quality.
