Over the years, my father and I had tried quite a few
different breeds. We started in the late 1980s with a mix of
Rambouillet, Hampshire, Shropshire and Suffolk ewes. These were
crossed with Dorset rams. Around 1998 we
knew we had to change something. From '88 to '97 our average
weaning rate was 1.33 lambs per ewe. We were not making a whole
lot of money for the work involved. So, we brought in Polypay and
a Romanov x East Friesian rams. The first thing we noticed was
that ewe lambs could be as productive as mature ewes. Our ewes
starting raising triplets successfully. From 1998 through 2007 my
dad's flock weaning rate averaged 1.56.
In 2001, I
started my own flock of Polypay, East Friesian x Romanov and
Columbia ewes. My first lambing was in 2002. From 2002 through
2007 my flock weaned an average of 1.7 lambs per ewe. During that
time I was searching for the perfect breed/cross. My flock had two
types: very prolific ewes, which were harder to manage and "easy care"
sheep that I hoped would work with well with my off-farm employment.
The very prolific ewes were a mix of Romanov, East
Friesian and Polypay breeds. These sheep were harder to manage
because they required better health and nutrition practices, required
more help at lambing and often had more orphan lambs (especially the
Polypays). The "easy care" sheep were Columbia crosses which were
big and tough, but not especially prolific. The very prolific sheep
were more profitable, but it seemed a guy could handle more of the "easy
care" sheep, so I continued with a split flock.
Then
came the ethanol mandate. In 2005, corn averaged $1.76 per bushel
and lambs were $1.05 per pound. By 2007, corn was running $3.37 a
bushel and lamb fell to $0.97. If we thought things were bad in
1998, they looked downright hopeless in 2007. My father sold his
flock. That fall, I took a few days to strategize on a plan going
forward. I came up with a software system that would help me
manage my flock based on sound business principles. Two things
became clear: I had to cut costs (especially feed costs) and I hand to
get my unit production up. The "easy care" sheep had to go.
I now have a flock that is primarily Polypay, East
Friesian and Romanov crosses; some Suffolk ewes were recently added as
well. Over the last few
years I've progressed from searching for the perfect breed/cross
to seeking individual animals with exceptional production.
While there are certainly differences between breeds, there is probably
as much variation within a single breed as there is across breed
averages. Consequently, I am always looking for exceptional
individual animals, regardless of breed. Still, it is obvious that
there is a better chance of finding those individuals in some breeds
than others. The odds of finding a Southdown that can meet my
production requirements is lower than that of a Polypay.
I have identified the following breeds to have the most potential for my
system, but am open to any animal that has shown exceptional production
performance.
Polypay:
I have been raising Polypay sheep for nearly 15 years .
Based on NSIP data, it would seem that the average Polypay
cannot really out-produce an average Suffolk, especially
for feeder lamb production. However, a top-end Polypay can be
incredibly productive. Over the last 5 years, my mature Polypays
have weaned 2.11 lambs per year that finished to 138 lbs.
East Friesian:
If your ewes have a lot of triplets and quads, it doesn't take long
to figure out that milk is a limiting factor. East Friesians add
milk production, growth and prolificacy. Over the last 5 years, my
mature high-percentage Friesian cross ewes have produced 2.03 lambs that finished to 135
lbs. The big advantage of the Friesian is in the weaning weights
and first year performance of the ewe. Friesians cross ewe
lambs wean lambs that are much heavier than other breeds.
In 2011, Friesian-sired ewe lambs weaned twins that were 10% heavier
than the twins weaned by Polypay-sired ewe lambs and had total litter
weights 40% higher!
Romanov:
I have not been especially impressed with Romanovs as a pure breed.
Over the last 5 years my mature Romanov ewes have produced 2.30 lambs
averaging 112 lbs (not Romanov sired lambs). I find their value is
in cross breeding. My mature 1/4 Romanov ewes produce 2.28 lambs
per ewe that finish at 128 lbs.
Finn:
I don't have any Finnsheep at this time, but may in the future.
I would generally prefer a Romanov to a Finn.
Rideau:
I don't have any Rideau sheep at this time, but am very interested
in importing some semen from Canada. I think this breed could
outperform Polypays.
Suffolk:
It is hard to match the growth performance of Suffolks. The
problem is that some breeders have sacrificed too much to obtain that
growth. Fortunately, there is a lot of diversity in the Suffolk
breed. There are still some moderate-framed, heavy bodied Suffolks
out there. In 2010 and 2011, I added a total of 9 heavy-bodied Suffolk ewe lambs. I am hoping to mate them to some
maternal rams to infuse growth into the gene pool without
sacrificing maternal characteristics. They will not be given any
preferential treatment; if they can perform, I will retain their
daughters; otherwise they will be culled.
Charollais:
I have had limited experience with Charollais, but was very
impressed with them for light to medium weight lamb production.
The vigor of the lambs at birth is very good. The muscling is
incredible and they have almost a magical ability to condition on
pasture. I sold my ram but kept a son from him (Suffolk dam).
