Learn about recommended protocols for artificial insemination of beef heifers using 1-Shot PG, 7-Day CO-Synch + CIDR, 5-Day CO-Synch + CIDR, 14-Day CIDR-PG, and MGA-PG in this University of Missouri Extension guide.
The Random Shuffle of Genes: Putting the E in EPD
Revised
Understanding EPD variability: how genetic shuffling during reproduction leads to differences among full siblings in cattle.
Using Beef Cattle Sire Summaries: A Practical Guide to Selecting Better Bulls
Revised
Learn how to effectively use sire summaries to make informed breeding decisions, enhancing herd genetics and productivity.
Selection of Replacement Heifers for Commercial Beef Cattle Operations
Revised
To maintain herd numbers, commercial cow-calf operations must buy or develop females to replace culled cows. Learn about different strategies so you can make the most economical decision for your farm or ranch with long-term profitability in mind.
Production Records for Commercial Cow-Calf Operations
Reviewed
Track key metrics like breeding, calving, and weaning to enhance cow-calf herd productivity and profitability through effective record-keeping.
Beef Cow Nutrition Through the Year: Managing for Efficient Reproduction
Reviewed
Profitable cow-calf operations manage so that a large proportion of the cow herd calves in the early portion of a short calving season. In order to maintain this, cows need to conceive on approximately a 365-day calving interval.
Reproductive Anatomy and Physiology of the Bull
Reviewed
Good reproductive performance of a bull is necessary to obtain a high percent calf crop when natural service is used for breeding. Gain a basic knowledge of the reproductive tract and an understanding of the bull’s reproductive system in this guide.
Guide to Estrus Synchronization Products
Reviewed
Several protocols and other resources allow beef producers to effectively synchronize estrus and ovulation in the herd. Read this guide for an overview of the function, handling considerations, and proper administration of estrus synchronization products.
Calving Season Considerations for Commercial Beef Cattle Operations
Reviewed
Explore key factors in choosing the best time of year to calve for improved efficiency, herd health, and profitability in beef cattle operations.
Preparation and Handling of Catheters for Artificial Insemination of Cattle
Reviewed
Learn proper semen handling to achieve maximum conception rates with artificial insemination in beef cattle. Reduced conception rates occur if semen is handled improperly before, during or after thawing. See this illustrated MU Extension guide for more.
Determination of Pregnancy Status in Beef Herds
Reviewed
Pregnancy examination provides valuable information that enables cow-calf operations to make management decisions that increase profitability and improve long-term reproductive efficiency. Learn about several methods in this MU Extension guide.
Reproductive Management of Bos indicus-Influenced Beef Cattle
Reviewed
Bos indicus cattle present challenges with estrus synchronization. Learn about the timing of estrus onset for them, their susceptibility to stress, and considerations and expectations when breeding them in this University of Missouri Extension guide.
Understanding and Minimizing Pregnancy Loss in Cattle
Reviewed
This publication details some common causes of pregnancy loss and provides management practices that can help minimize the incidence of pregnancy loss.
Determining Reproductive Fertility in Herd Bulls
Reviewed
Learn how to assess and enhance bull fertility through breeding soundness evaluations, puberty indicators, and nutrition strategies.
Care and Maintenance of a Liquid Nitrogen Tank
Reviewed
Semen is a significant cost in a cattle artificial insemination program. Maintaining a liquid nitrogen tank’s integrity is key to protecting that investment. Learn how to properly care for and maintain a liquid nitrogen tank in this MU Extension guide.
Artificial Insemination of Cattle Step by Step
Reviewed
Using correct techniques when performing artificial insemination on beef cattle can help ensure success and minimizing risk of injury. Learn how to deposit the semen in the proper location in the female reproductive tract while using sanitary techniques.
Herd Health Programs and Reproductive Efficiency of Beef Cattle
Reviewed
Comprehensive herd health programs enhance reproductive efficiency in beef cattle by addressing disease prevention, nutrition, and environmental stressors.
Nutritional Management of Developing Heifers: Intensive Versus Extensive Systems
Reviewed
This publication aims to provide insight on prudent nutritional management of developing heifers while discussing the pros and cons of various heifer development systems.
Reproductive Anatomy and Physiology of the Cow
Reviewed
The ability of a cow or heifer to successfully mate, conceive, give birth, and raise a healthy calf each year is essential for profitable and sustainable beef production. A good understanding of anatomy and physiology of both the male and female is helpful in successfully managing reproduction.
