EWE Management Weaning to Mating. If there is a starting point for the preparation of ewes for the breeding season, then it is probably at weaning.

At least two months should be allowed between weaning and mating, so that ewes have time to recover from the rigours of. This is a must have for any sheep breeder.

Have consulted this book over and over. Everything from nutrition recommendations, lambing, disease and abnoramilty causes and treatments, to Ewe care. We just had twin lambs last night, Ewe for whatever reason has not come into milk yet so out came the trusty handbook to verify the dosage of Oxytocin /5(33).

Good management of lowland sheep depends on strategic uses of resources during the management cycle and manipulation of body reserves. Critical periods are around mating, late pregnancy and early lactation.

Good condition at mating is achieved by expanding the grazing area apportioned to the ewes in autumn. Thereafter, ewes are restricted to allow Cited by: 1. Lowland ewes should be in body condition score of to 3 at lambing and hill ewes 2 to If any are thin at vaccination time, they should be pulled out and fed preferentially.

Any underlying reason for the thinness should be investigated (e.g. teeth, liver fluke). Ewe lamb mating management The “ram effect” can be used to induce ewes (ewe lambs or adult ewes) to start cycling provided they are sufficiently close to the time of onset of normal cyclicity but have not entered their breeding season.

The schedule for exploiting the “ram effect” was discussed in detail in the last article (published on. • Use one teaser for ewes • Put teasers with ewes for up to 17 days - no longer • Remove before fertile rams go out • Increase ram power to 1 ram to 30 ewes.

Raddles Raddle marks are a useful management tool. They show you how tupping is going. They also help improve the accuracy of feeding, management and.

Breeding from ewe lambs Information provided by the ADAS Beef and Sheep Group Compiled by Dr Elwyn Rees and Kate Phillips. Key messages + Lambing ewe lambs can improve the financial viability of a sheep system.

+ Up to 55% of English lowland flock replacement females could give birth at one year of age. + Ewe lambs have lower fertility than matureFile Size: KB. Sheep Management Systems Sheep can be produced under many production systems in New Mexico.

Here are some things to consider when designing a sheep production system: Available forage. Plan to make maximum use of seasonal forage because feed costs often amount to 50 to 60 percent of the total cost of producing lamb and Size: 1MB.

Even when management and nutrition are proper, more lambing problems will be encountered with ewes lambing for the first time at 12 to 14 months of age.

While breeding ewe lambs increases their lifetime productivity, it may not be economically advantageous for all producers.

The most common system of accelerated lambing is three lamb crops in two years, resulting in an average lambing interval of 8 months or lambings per ewe per year.

The 3/2 system is usually characterized by a fixed mating and lambing schedule, such as May mating/October lambing, January mating/June lambing, and September mating/February. Good management of lowland sheep depends on strategic uses of resources during the management cycle and manipulation of body reserves.

Critical periods are around mating, late pregnancy and early lactation. Good condition at mating is achieved by expanding the grazing area apportioned to the ewes in by: 1. Ensure that a target BCS of for lowland ewes is achieved well before mating.

A ewe may lose BCS during pregnancy, and you want her to reach the target BCS of at lambing. Ewes should be grouped according to the number of lambs scanned and BCS.

Each group can then be fed accordingly. Ewe lambs should be fed 20% extra compared to the. Twice-a-year lambing. Out-of-season mating. Twin or triplet lambing through use of hormones or new breeds• Artificial insemination.

Early weaning and lamb nurseries. Ultrasonic pregnancy checking (using sound waves) and timely rebreeding or culling. Ram fertility and competence testing.

Predator avoidance and control. First-year lambing of ewes. Lambs – After eight weeks lambs derive most of their energy from grazing, therefore the ewes are competing with their lambs for grass.

Prioritise the best grazing for weaned lambs. Thin ewes – Thin ewes need sufficient time and a good diet to reach the optimum BCS at tupping. One BCS equates to 12% of a mature ewe’s Size: 1MB. Ewe lamb mating management.

Evidence suggests that it would take a 35 day joining period for first mating to be achieved by 90% of a ewe lamb flock. As ewe lambs have a lower pregnancy rate per oestrus than mature ewes, only 70% (approximately) of the animals would be pregnant after a 35 day joining period.

Mating not followed by pregnancy may present as ewes being marked repeatedly, a spread-out lambing period, and/or poor prolificacy in the ewes. Many of the reasons for failure to mate can also influence failure to achieve pregnancy.

The period from weaning to mating is important for preparation of ewes and rams for good reproductive performance. EWE WEIGHT AND CONDITION FOR MATING A good lambing percentage is largely achieved by early preparation between weaning and the next mating. Ewes need to be in good body weight and condition (CS3) for high ovulation rates at mating.

After a lambing, put the ewe and the lamb into the jug. Strip the ewe’s teats and “snip and dip” the lamb’s umbilical cord.

Make sure newborns get colostrums within 2 hours of birth. Give the ewe warm molasses water. Dock lambs’ tails when they are 2 to 3 days old and castrate male lambs when they are about 10 days old. ha of green land for mating, lambing and for ewes with singles males to weaning. Wether lambs were sold to export market for light lamb – some were finished indoors.

Lowland System ( ewes) – ewes spend about 30% of the year on the hill and had use of ha of green land for mating and from lambing to weaning. Ewe breed has been shown to influence lamb output of both hill (Carson et al., ) and lowland (Carson et al., ) flocks through its effects on litter size, lamb birth -E-mail: Growth targets for ewe lambs.

Ewe lambs can be joined from seven months of age, as long as they are at least 45 kg at joining and are provided with quality feed to continue to grow after joining through pregnancy to lambing. If ewe lambs achieve these targets, acceptable reproductive performance among ewe lambs can be realised.

system, eg hill or lowland, breed of ewe, time of year and ewe prolificacy. Preliminary results for the AHDB-funded sheep KPI project supports the hypothesis that BCS at key stages of the production cycle, is an appropriate KPI to predict weaned lamb weight.

At tupping, lowland ewes should have a condition score of -hill ewes – Ewes in CS at tupping should be on a rising plane of nutrition, so move ewes on to good, plentiful grass a couple of weeks prior to tupping.

If grass supply is poor, you can compensate by feeding some concentrates. Ewe lambs begin cycling later than mature ewes and their mating season is shorter in duration. It is likely that even in well grown lambs up to 20% will not become pregnant.

Ewe lambs have a shorter heat and are more reluctant to seek out rams; therefore more rams should be used and confine animals to a small area of land. The animals were kept in a single flock under intensive management and milked twice daily starting at lambing.

Lambs were removed from the ewes at birth into an artificial rearing : Elisha Gootwine. Ewes will normally be 2 years old before they become a breeding sheep. Scanning. Like humans, ewes are scanned on farm to find out how many lambs they are carrying.

The ideal number of lambs for a ewe to have differs depending on the farming system. Hill farms prefer ewes to have just one lamb, while sheep in the lowland strive to have twins. The aim on lowland farm is to have twins, as ewes have two teats on their udders so can rear two lambs.

However, single births and triplets are common, and quads and quins not unheard of. After scanning, ewes are usually split into groups according to how many lambs. stock (Lowland or Hill) held, or where there is a mix, the ratio stock type held and as reported in the Annual Sheep Census – • Applicants with greater than 50% lowland ewes must choose from the options for Lowland flocks • Applicants with greater than 50% hill type ewes must choose from the options for Hill flocks.

Mating book. The following data is recorded: ewe number, first, second, third service, date of service and sire. Lambing book should record: ewe number, lambing date, lamb number, sex of lambs, birth weight, sire, weaning weight, age at weaning and liveweight of lambs at days.

Simple ewe management strategies can greatly increase lamb survival rates. Having a thorough understanding of the breeding cycle, and identifying health issues early, will help you maximise your chances of sheep breeding.

The resultant F1 ewe is a prolific, heavy-milking mother with longevity and hardiness. No ram lambs are retained for breeding. These ewes are then bred to a terminal sire (eg, Suffolk or Texel).

The offspring of this mating–a terminal cross–gain well and have good carcass characteristics. Carry out all ewe preparations for tupping, including veterinary treatments at least three weeks before mating.

Ewe lambs should be at least 75 per cent of mature body weight at mating. This means that, for a lowland crossbred flock with an average mature weight of kg, ewe lambs need to be more than 45 kg at mating.

Managing rams before Author: Margaret Donnelly. Mate the ewes so that they lamb when grazing is plentiful. Lambs will then have a better chance of survival.

It also prevents the buying of expensive feed and the lambs are ready for the market at an early age. Limit the breeding season to 6 weeks to include two oestrus cycles. When the mating season is too long, flock management (dipping,File Size: KB. Sheep Breeding Management.

Sheep Breeding Management Practices #1: The ideal male sheep and female sheep ratio should be Sheep Breeding Management Practices #2: For better mating chances, young male sheep (rams) should be put in to experienced older ewes (female sheep) flock and older rams (male sheep) to younger ewes (female sheep).

A ewe should only be assisted at lambing if an examination reveals that she is unlikely to lamb successfully on her own or that further delay may jeopardise the life of the lambs. Ewes that have been unwell during pregnancy are best penned up in a separate area for ease of observation.

The shorter joining period also helps with better ewe & lamb management. Scanning – Ewes should be scanned at days from the time the rams were put in with the ewes. This allows the best time for viewing as the lambs have developed enough to be effectively seen but are not too large so as to impede view.

This chapter describes reproductive management, nutrition and disease control, with regards to the requirements for reproduction and mating management.

Onset of the breeding season in sheep is driven by short day length. Sheep are short‐day breeders so, for most breeds originating from northerly latitudes, the natural mating period is in autumn. 5 months pregnant – 3 months looking after lambs – 3 months dry period.

Sexual behavior. Ewes generally reach sexual maturity at six to eight months of age, and rams generally at four to six (ram lambs have occasionally been known to impregnate their mothers at two months).

Sheep are seasonally polyoestrus animals. Ewes enter into oestrus cycles about every 17 days, which last for approximately 30 hours. In addition to emitting a scent, they .Many management alternatives are available to the commercial sheep producer.

One major distinction among these alternative production systems is the season in which lambing occurs. Fall lamb production. For fall lambing, an abundant supply of fall and winter forage, small-grain pasture, alfalfa stubble, or other crop residue is necessary.For early lambing ewes, mated in August, the availability of grass is such that steps have to be taken to restrict herbage allowance to maintenance during the first month of pregnancy.
