Breeds of sheep: if you have any questions.

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!


Breeds of sheep: if you have any questions.

  • 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!


Hampshire if you have any questions.

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!


Rambouillet if you have any questions.

  • 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!


Romney if you have any questions.

  • 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.

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

Help!


Welcome to Purdue University’s Sheep Unit!! practices at the Purdue Sheep Unit!

Help!


Purdue Sheep Unit practices at the 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!


Reproductive Traits: practices at the Purdue Sheep Unit!

  • 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!


Common practices to prepare ewes for lambing practices at the Purdue Sheep Unit!

  • 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!

DEFINITIONS industry unit!!:

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


DEFINITIONS industry unit!!:

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


DEFINITIONS industry unit!!:

Gestation: the period of pregnancy from conception until parturition.


DEFINITIONS industry unit!!:

Estrous:the time between standing heats


DEFINITIONS industry unit!!:

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


DEFINITIONS industry unit!!:

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. 


DEFINITIONS industry unit!!:

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.
