Breeds of sheep:

Did you know???

  • There are 47 breeds and types of sheep in the United States.
  • The breeds of sheep in the United States provide a diverse range of performance for growth, carcass merit, reproduction, milk and wool characteristics.

Help!

slide8

Breeds of sheep:

  • There are 6 different types of breeds in the United States.

Meat breeds

Dual purpose

Fine wool breeds

Hair breeds

Long wool breeds

Minor breeds

Click on the types to learn about an example of that breed type.

Help!

slide9

Hampshire

Wool cap

  • Meat type breed of sheep
  • Used as a source of terminal sires for commercial lamb production.
  • Large in size, moderately prolific. They also have a wool cap on their head with a black face and medium wool fleeces.
  • Hampshire sheep have very good milking abilities, as well as good growth and carcass cutability.

Help!

slide10

Rambouillet

  • The Rambouillet is the foundation breed of most U.S. range flocks.
  • They have an extended breeding season and produce a high quality fine-wool fleece.
  • They are white-faced in appearance with wool on their legs.
  • Rambouillets are the largest of the fine-wool breeds, rugged, and adaptable to a wide variety of arid range conditions.

Help!

slide11

Romney

  • The Romney is a medium-sized, white-faced breed with wool extending on their legs.
  • They make good mothers, and have average or better prolificacy, as well as good milk ability.
  • Romney’s produce a coarse, long-stapled fleece that is well-suited for spinning.

Help!

slide12

Columbia

  • The Columbia is the first breed developed in the United States.
  • They are a hardy and social breed that make good mothers.
  • Columbia’s have white faces with wool extending down the legs.
  • The Columbia is a dual purpose breed because they’re commonly used as terminal sires to produce fast growing, lean market lambs but also produce heavy, medium-wool fleeces with good staple length.

Help!

slide13

Katahdin

  • The Katahdin is a wool less breed of sheep that originated in Maine.
  • They have excellent mothering abilities, good milkers, and quite prolific.
  • They have an extended breeding season.
  • Very tolerant of environmental factors such as heat, humidity, and cold.
  • They are the largest of the hair breeds and naturally produce a lean and well-muscled carcass with good flavor.

Help!

slide14

Shetland

  • The Shetland is a primitive breed and also one of the smallest breeds.
  • They have a natural hardiness, good lambing ease and longevity.
  • They also are able to survive harsh environmental conditions.
  • Shetland sheep are known for their production of colorful wool upon which the Shetland woolen industry is based.

Now its time to learn about some general management practices at the Purdue Sheep Unit!

Help!

slide28

Purdue Sheep Unit

  • Manager: Gerald Kelly
  • Purdue’s sheep unit is home to 350-400 ewes annually, with half of the ewes lambing in the fall (non-traditional) and then traditional lambing in the spring.
  • There are approximately 50 acres of alfalfa, orchard grass, red clover, and birds foot trefoil pastures contained in seven-wire, predator control, high-tensile fence.
  • Provides facilities for research for intensive efforts in nutrition, reproduction, physiology, neuroendocrinology, and biomedical research.
  • Research, teaching, and extension activities are daily activities that take place, as well as the daily care of all animals.
  • The objectives of the sheep unit are to improve the quality of animal protein and increase efficiencies of production.

Help!

slide29

Reproductive Traits:

  • Sheep are seasonally anestrous and usually bred in the fall to lamb in the spring.
  • The gestation length is typically 144-152 days depending on the breed.
  • The estrous cycle is generally 16-17 days in length.
  • The estrus period is typically 20-42 hours
  • Age of puberty is 5-8 months
    • Typically breed ewes at 9 months if appropriate size/weight.

Help!

slide30

Common practices to prepare ewes for lambing

  • Vaccinate ewes with CD/T around 4 weeks before lambing to ensure passive immunity.
  • Shear ewes 6-8 weeks before ewes are scheduled to lamb.
  • Feed ewes an additional feed supplement for the last 6 weeks of gestation.
  • Ewes carrying twins and triplets should be separated from those ewes carrying a single so they receive more supplement.

Help!

slide32

DEFINITIONS:

Terminal sire: Used for the breeding of market animals. “Terminal” refers to the offspring from mating\'s being used for market or “terminated”.

slide50

DEFINITIONS:

Prolific: producing offspring in abundance. Sheep usually have twins or triplets. High prolificacy means greater chances of having multiples.

slide51

DEFINITIONS:

Gestation: the period of pregnancy from conception until parturition.

slide52

DEFINITIONS:

Estrous:the time between standing heats

slide53

DEFINITIONS:

Estrus: standing heat, ovulation usually occurs towards the end of standing heat in sheep.

slide54

DEFINITIONS:

CD/T vaccination: Vaccine usually used to protect healthy sheep against the three aforementioned clostridial diseases. It should be administered to ewes during their last month of pregnancy. 

slide55

DEFINITIONS:

Passive Immunity:Immunity in sheep is passed through the ewes milk to the lambs. Maternal antibodies that are passed to lambs will protect them for six to eight weeks so long as they consume adequate amounts of colostrum.
