How do you get sheep to cycle?
Acyclic, seasonally anestrous ewes can be induced into estrus and ovulation with exogenous melatonin. Ewes are given melatonin 6 weeks before joining and are isolated from rams during that period. The joining period should cover two complete estrous cycles (35 days).How long does it take a sheep to cycle?
The average length of cycle used for sheep is 17 days. Figure 3 shows the length of 1,038 estrous cycles for 299 different ewes: 90% of the cycles were 14-19 days long, with an average of about 17 days. The start of the estrous cycle is considered to be when ovulation of an egg occurs from the ovary.How do you make a sheep ovulate?

- the use of teasers and the 'ram effect. '
- short term flushing with a high energy diet.
- use of products such as 'Ovastim' to increase ovulation rates.
- use of melatonin containing products which 'trick' the animal's reproductive system into thinking the days are shorter which triggers ewes to cycle.

The onset of the breeding season can be manipulated by:
- The ram effect.
- Melatonin implant.
- PMSG injections following progesterone sponges.
Why are my sheep not breeding?

Animals pair during a period of 'ruttishness'. The ewes are restless, shake their tails repeatedly and have a slightly swollen vulva. Note, however, that these signs are not as obvious in sheep as in cows. This is followed by a 'breeding rest', during which pairing does not take place.How do you increase lambing percentage?
A high ovulation rate (OR) is the first step in achieving a high lambing percentage. High ewe live weight and live weight gain during mating causes high OR - for each extra kg of ewe weight there will be 1-2% higher lambing percentage. A 10% increase in OR causes 6.9% more lambs born and 5.7% more lambs tailed.What month do sheep mate?
Specifically, sheep are short day breeders, breeding at times of the year when the day length is shorter and night time longer. Thus, ewes are normally sexually active (show 17 day oestrous cycles) mid-Autumn into Winter, and sexually inactive (anoestrous) from late winter through to autumn.What is the best breeding method for sheep?

Feeding a mineral and protein supplement can help provide additional nutrients needed to support sheep fertility, especially when forage quality and quantity decline. A good rule of thumb is to start supplementing protein 30 to 45 days before grass starts to visually decline.How can I improve my sheep breeding?
For increasing breeding efficiency by shortening the frequency of lambing the most suitable system is lambing three times in two years.

The joining period should cover two complete estrous cycles (35 days).How soon after giving birth can a sheep get pregnant?
After lambing, an average of 17 to 21 days is usually required before the reproductive tract will return to normal so ewes can begin to show estrous activity, if in the season of the year that will allow it. All ewes are in an- estrus for at least 17 to 21 days after lambing, regardless of the season.How can I increase my sheep's ovulation rate?
An increase in ovulation rate is the next step to lift the number of lambs conceived by those ewes that ovulate. This outcome can be achieved either by feeding supplements with highly digestible crude protein or by grazing improved pastures high in crude protein protected from rumen degradation.How many lambing pens for 100 ewes?
Lambing pens should be a minimum size of 2m x 1m, with 13 small pens allocated per 100 ewes. If you have synchronised your ewes, then there will be a considerable increase in the number of pens required – up to 3 times as many.What is the best feed to fatten up sheep?
The major sources of feed for fattening sheep are roughages, agro-industrial by-products, local brewery by-products, household food leftovers and screenings from cereals.

Birthing SheepWe average three born lambs per ewe, but have had as many as six! This high birth rate can present some challenges during parturition or delivery: Sometimes the lambs get tangled up in utero and more than one enters the birth canal at once and just like a traffic jam, they can't get through.
How long is a ewe pregnant?
The ewe's gestation period ranges from 144–151 days in length, with an average of 147 days. The date that the first lambing is to be expected can be calculated from the date of the first exposure of the ewes to a fertile ram.How to tell if a sheep is about to give birth?
'How can you tell when a sheep is in labour?'Licking the lips – a preparation for cleaning the lamb after it is born. Restless standing up and lying down. Pawing at the ground – scratching up a soft 'nest' for the lamb to be born into. Visible straining at regular intervals.
What is the best breed of sheep for beginners?
Consequently, novice sheep producers should probably not raise breeds of sheep that commonly produce triplets or quadruplets (e.g., Finnsheep or Polypay). If labor is in short-supply and annual shearing is a major burden, hair sheep breeds such as Dorper, Katahdin, Saint Croix, or Royal White might be a better fit.How many times a year do you breed sheep?
Most breeds of sheep only come into season once every 12 months, so each animal is only likely to produce one to two lambs during each year.How to help a sheep give birth?
If the ewe is roomy or the lamb is not large, often one can pull the lamb with the leg back.
