Breeding sheep can be complicated. Four months, three weeks and four days, or 142 – 148 days: that is the gestation period of a lamb. Our shepherd, Christopher, uses that calculation to determine when to put the rams into the flock. We want our ewes to start to birth their lambs the second week of May, when the pastures should have sufficient green growth to support the ewes. It is much warmer and dryer for the newborns to plop onto grass in the fields, rather than in muddy barnyards.
In the late fall, Chris works to ensure a ‘rising plane of well-being’ for the ewes, calculating the quality and quantity of the food they receive so that their bodies are confident that all is well. This increases the probability of more ova being made available for fertilization; thus multiple births. We aim for an average of two lambs per mature ewe and one lamb per first year mama (known as “ewe lambs”). There are of course many additional factors in fertility, including genetics.
Our goal is always to create great-tasting lamb.
We now use mainly North Country Cheviot and Suffolk purebred rams to breed the ewes. They are put to 5 groupings of females: 2 larger groups of mature ewes totaling close to 800 (with 21 rams); 2 much smaller groups of purebred Suffolks, mature and young ones, to be bred by 2 Suffolks; then the Border Cheviot (a much smaller breed) rams will join the 300 ewe lambs. The latter produce a smaller, feisty lamb with a high drive for survival (which helps their inexperienced moms).
The two Teaser Rams (those with vasectomies) have finished their work to get the ewes in the mood by December 17th this year, the date the 25 intact rams head eagerly into the fields.
The 5 groupings of sheep are protected carefully by our 9 Maremma and Akbash guardian dogs. We hope to keep stress to a minimum, from predators and from weather – the latter of which of course we can’t control at all.
Healthy, happy lambs make great sheep and wool.
Our cycle begins again.
Topsy Farms produces beautiful washable wool products including sheepskins, six point wool blankets, wool for knitting and felting, and some of the finest local lamb in Ontario.
