Ewe Lactation & Lamb Finishing

Ewe Lactation and Lamb Finishing - South Island

Ewe lambing, lactation feeding and lamb finishing are the final important feeding periods of the sheep production system. It is important to note that breeding units and lamb finishing will not always occur on the property. They can often be described by two distinct periods:

PRE-WEANING SYSTEM

The breeding unit will often try to maximise the carrying capacity of the capital ewe flock to maximise the numbers of lambs at weaning.

The success of this system is often linked to the production potential of spring conditions.

While planning and farm management plays a major role in a successful season, grass cultivars and forage choices can greatly influence this late winter and early spring period.

Mid heading ryegrass

Samson and Reason AR37 or AR1 as well as early heading tall fescue such as Hummer and Haven have a significant influence on feed supply through September and October

Late heading ryegrass

Legion AR37, or Legion AR1 can be used in general sheep systems, having excellent density for periods of set stocking and winter grazing. Legion has a good spring growth habit with low aftermath seeding in summertime helping with pasture quality into autumn

Legumes and herbs

Relish red clover and Ecotain® environmental plantain have been proven to greatly influence weaning weights and ewe body condition at weaning

Lucerne

Torlesse and Titan 5 lucerne are very effective through mid to late lactation in
dry environments

EARLY SEASON SHORT TERM PASTURES

Manta diploid Italian ryegrass demonstrates very strong establishment and winter growth, peaking in performance through late September until the end of its first summer. While Manta is currently Nil endophyte, it has a particularly strong second winter growth habit which is productive and highly visual. With its strong establishment, Manta is ideal for undersowing into thinning or run-out pastures.
Mohaka AR37, or Mohaka AR1 tetraploid hybrid ryegrass has a role in short term high-quality pastures that may last 2-4 years and are ideally mixed with Relish red clover, Brace white clover and Ecotain environmental plantain.

POST-WEANING FINISHING SYSTEM

This system can occur for a property with the land type and scope that can maintain a finishing system post weaning. This can include farms with a capital ewe flock or it can be farms that trade in lamb finishing through summer, autumn and winter.

The extent of this system’s profitability can be vulnerable to the buying and selling margin of the store stock. Forage quality and timeliness of forage supply often define the success of these systems.

High-quality new pastures

Often considered finishing pastures, these will have significant legume and herb content in their first 2-3 years

Herbs and legumes

Choice chicory is a productive option in the summer and may also include Relish red clover and Attribute white clover, which can last for at least 2 years
Ecotain® environmental plantain, Relish red clover and Attribute white clover provide both summer and autumn/winter feed options for finishing
Relish red clover and Nomad white clover provide an option for summer and autumn finishing

Summer brassica

Excellent options for high liveweight gain potential through hotter summer months and come in many different starting date options

Hunter leafy turnip is ideal to start grazing 6-8 weeks from sowing
Mainstar rape, 10-12 weeks from sowing
Spitfire rape, 13-14 weeks from sowing
SovGold kale can provide useful winter feed crops, however early sown crops can be grazed early with sheep to manage stem height and maximise utilisation
