Company Goals
OUR MANAGEMENT Products and Services Available

Cergin Livestock Company is located 4 miles east of Marsing, Idaho, overlooking the Snake River. We raise purebred Suffolk sheep, purebred Rideau Arcott sheep and market lambs from our flock of commercial cross. We also sell Deccox, Merrick's Super Lamb Instant Milk Replacer, Special Feed Pellet and Trace Mineral Salt products.

Our Suffolk sheep flock has been enrolled in the VSCF Program for 15 years and has been certified free of scrapie for 9 years. The purebred Suffolk sheep flock is genotyped and all of the sires are codon 171 RR genetics.

We believe Suffolk sheep should be meat animals, not race horses and have bred them accordingly, selecting heavily for twinning, milking, weight gain, good feet, legs and survivability. For example, our Suffolks average greater than 190% live lamb crop and twin buck lambs average around 1.0 lb/day gain. We consistently top the Idaho Wool Growers Ram Sale with our Suffolk ram lambs.

Rideau Arcotts, a medium sized sheep, were developed at Agriculture Canada-Ottawa Research Station as a ewe breed. They breed out of season, have multiple lambs and milk well. They were developed from the Shropshire, East Friesian, Finnish Landrace, Dorset and Suffolk breeds. Ours generally have a 240% lamb crop.

Cergin Livestock Company's 300 to 400 head commercial sheep flock is mostly made up of offspring of Arcotts and Arcotts/East Friesan crossed ewes and a Suffolk ram. (No, the crossbred sheep were not a mistake or the result of rams getting in with the wrong group of ewes.)

The Arcott and Arcott/Friesian ewes crossed with Suffolk rams yield medium-sized, brown faced lambs that are very vigorous at birth and tend to gain better than the pure Arcott lambs. The cross ewes consistently twin and triplet, milk very well and raise their triplets. They help us achieve a lambing rate over 200%.

When the Arcott/Suffolk or Arcott/Friesian/Suffolk ewe crosses are bred back to Suffolk rams, resultant F2 lambs are black faced, fast growing, great market lambs.

Cergin Livestock Company's entire flock is closed;
only herd sires have been introduced over the last 20
years. Our Sheep are free of Johne's disease, foot rot, spider disease, epididymitis and OPP.


We identify and weigh our lambs within 5 days of life and keep excellent records. We vaccinate our lambs routinely with Clostrial vaccine (one containing Clostridium sordellii ), and our ewes are additionally vaccinated against Campylobacter (abortion) and Corynebacterium pseudotuberculosis (abscesses).

We designed our own trace mineral salt specifically for our sheep and have it manufactured and packaged in 50 lb bags. This mix is ideal for our sheep and sheep in our arid mountain region. It has no added copper, 90 ppm of selenium, Vitamin E to boost immunity, zinc to enhance fertility and hoof health, iodine, cobalt and other necessary minerals. We do make this salt available to other sheep producers.

We mix Deccox® into our trace mineral salt and feed this mixture free choice before and after lambing to ewes and lambs to control Coccidia. This procedure nicely controls the ubiquitous intestinal parasite which, even if not causing diarrhea, does reduce weight gains. If you would like to try this management tool, contact Marie mbulgindvm@gmail.com.

We feed our lambs a pellet we developed for maximum weight gain, feed efficiency and health and is fed with good quality alfalfa hay or pasture. It contains ingredients for the control of some common feeding problems i.e. urolithiasis (bladder stones), acidosis (grain over-load), bloat, and polio. This is provided free choice to market and ram lambs until they are sold and ewe lambs up to 6 month of age when they are taken off the pellet and left on pasture.
