Effects of Shipping and Heat Stress on Embryonic Mortality in Cattle

Nov 09, 2020

By Robin Salverson

Embryonic loss is the greatest economic loss in the cow/calf industry, affecting number of cows carrying to term and percent calf crop weaned.

Fertilization rates are usually between 90% and 100% when semen is present at ovulation. Fertilization usually takes place, but conception rates (number of animals that conceive divided by number of animals inseminated) are usually around 70% for natural service or artificial insemination.

Although nature (poor oocyte quality, disease, chromosomal abnormalities, etc.) contributes much of this loss, management practices can also increase embryonic mortality. Stress, particularly heat and shipping stress, can be detrimental to embryos and decrease pregnancy rates.

Video: What Does 20 MILLION Hogs a Year Look Like?

?? The Multi-Plant System Processing 20 Million Hogs Annually in the Midwest JBS USA operates multiple large-scale pork processing facilities across the Midwest, including major plants in Iowa, Minnesota, and Indiana. Combined, these facilities have the capacity to process approximately 20 million hogs annually.

Each plant operates high-speed automated slaughter systems capable of processing up to 20,000 head per day, followed by fabrication lines that break carcasses into primals, sub-primals, and case-ready retail products.

Hog procurement is coordinated through electronic marketing platforms that connect regional contract finishing operations and independent producers to plant demand schedules. This digital procurement system allows for steady supply flow and scheduling efficiency across multiple facilities.

Processing plants incorporate comprehensive food safety systems, including pathogen intervention technologies, rapid chilling processes, and integrated cold-chain management. USDA inspection is embedded throughout the harvest and fabrication stages to ensure regulatory compliance and product integrity. Finished pork products — from bulk primals to retail-ready packaged cuts — are distributed through coordinated logistics networks serving domestic and export markets.
