2023年1月3日 · Keeping feed costs low while still supplying the necessary nutrients to keep the flock healthy should be the goal of every shepherd. Listed below are some guidelines on feeding the flock. Because a ewe's feed requirements change as her reproductive status changes, there are several distinct feeding periods.

2023年9月8日 · Improved fertility improves farm efficiency by increasing the number of lambs produced per ewe (or per hectare) and reducing barren rates. Sheep farming is very seasonal; a few key events throughout the year directly impact …

2024年6月25日 · Nutritional management is one of the most important aspects of sheep production. Ewes that are fed appropriately are more fertile, milk better and wean more lambs that grow faster (Figure 1). Not only do well-fed ewes wean more pounds of lamb per year, but they are healthier and more resistant to disease than ewes that are under nutritional stress.

2020年9月1日 · Peak fertility for the ewe is from late September through November. Ewes will cycle every 16 to 17 days until they are bred or they reach the anestrous period. They are normally receptive to the ram for 24 to 48 hours. Once fertilization occurs, the ewe will give birth from 144 to 152 days after mating.

2024年11月18日 · When managing your ewe flock, understanding the breeding options available can help optimize genetic gain, improve flock productivity, and adapt to market needs. Three primary methods of breeding your ewes include natural service, artificial insemination (A.I.) and embryo transfer (E.T.).

2023年9月8日 · Ewe lambs should be at least 60 per cent mature bodyweight at breeding (Fig 2); however, focusing purely on size may select for singles and afect prolificacy of the flock. In lowland flocks that are aiming for 150 to 200 per cent scanning, it is advisable to select well grown, early-born twins as replacements to maintain twinning rate.

2025年2月18日 · This procedure assures that the ewe lambs produced by the sires used first are from some of the more fertile and prolific ewes in the flock. About two years of permanently identifying the ewes that lamb first and produce twins will give the producer a basis for separating out the best ewes for producing replacements.

The American Sheep Industry suggests 100% as the benchmark for small flocks with less than 200 ewes. Medium size flocks of 201 to 750 ewes should have a benchmark of 98% and larger flocks, particularly range flocks, should have a benchmark of 96%.

2022年11月15日 · Pasture stocking rates, ewe productivity, feed efficiency and lamb values all play a part in determining what size ewe is most efficient for a particular operation.
