Using the breeds discussed, make a booklet outlining their traits and names.
Then create a visual representation of the sheep in the booklet to help you remember what each breed looks like.

Why choose sheep?Why choose sheep?
Sheep can survive where cows can’t Sheep will eat problem weeds like Leafy
Spurge Profit per acre is the same for sheep
and cows, and usually higher for sheep Easier to get started due to less
equipment needed

Sheep ReproductionSheep Reproduction
Seasonal breeders - only breed in spring and fall
Gestation- 148 days Ewe lambs must be 100 lbs to breed Ram can service 12-15 ewes as a lamb,
and up to 100 as a yearling Most common = 3 rams / 100 ewes Usually not kept after 6 yrs

Marking harness - ram marks back of ewe with a crayon when mating
Change crayon colors every couple of weeks, if ewes are rebred, the first time was not successful
– may have a bad ram or ewe

Many lambs are lost in the first 24 hrs Twins - first born gets separated while
second is being born Assist difficult lambings Disinfect lambs navel with iodine

LambingLambing
Lamb should nurse within minutes, especially if cold weather
Strip teats to remove a mucous plug that seals the teat
Lamb may not be strong enough to suck the plug out and not get any milk, if he fails, he will quit trying and die

LambingLambing
Colostrum: mothers first milk (antibiotics) Keep ewe and lamb together for first 24
hours or more if the ewe doesn’t want to claim the lamb
Grafting: adopting lambs (triplets) onto other ewes (with singles or dead lambs)
– can be difficult to get ewe to claim lamb

RaisingRaising Identification: mark lambs with paint brands,
or ear tags or tattoo ears (purebreds) Docking: cut off tails
– tails are a bother
– between 1st and 2nd vertebrae of tail
– Elastrator: rubber band cuts off circulation
– Hot Iron: electric, heated knife stops bleeding

Castration: remove testicles
– Elastrator
– Cut with a knife
– Burdizzo crushes cords Dock & Castrate before 6 weeks old Wean at 5-6 months or 100 lbs..... Shear at least once per year, before
lambing (20-40% of income)

Culling: choosing animals not to keep for breeding purposes
Aging Sheep: less than 1 yr. = milk teeth– 1-2 yrs = middle two teeth replaced by 2
larger teeth– each year to 4 yrs = another set replaced– 6-7 yrs = begin to lose teeth (broken
mouth)

Increase nutrition 6 weeks prior to lambing until 1-2 months after lambing
Increase quality of feed not quantity
– stomachs shrink when pregnant due to lambs in uterus
Males - increase nutrition 6 weeks prior to breeding to build strength

Create a sheepCreate a sheep
1. Take out a sheet of paper 2. Draw a sheep (you don’t have to be an artist) 3. Name your sheep breed and list the following: 4. Wool color and type 5. Used for meat, wool, or both? 6. Any special traits (heat tolerant, cold tolerant, wet
adapted) 7. Using the supplies given, create a sheep (supplies
include construction paper, cotton balls, and anything students might have).
8. With this sheep, you must name it, give it traits, and give it color!

Some goats are used for meat and some for mohair (like wool)
But there are even some that are used for milk!

Angora Goat SelectionAngora Goat Selection
In selecting for fiber, one is interested in both quantity (weight) and quality of fiber (length, fineness, style, character, absence of kemp, etc.).
In addition to fiber, farmers are concerned with traits that contribute to the survival or viability (soundness, fertility, etc.) of the individual.
![Page 42: Breeds of Sheep. Objectives n Identify breeds of sheep n Describe the differences in the breeds n Discuss their uses based off of traits n Explain reproduction.](https://reader035.fdocuments.in/reader035/viewer/2022062516/56649e675503460f94b62dae/html5/thumbnails/42.jpg)
Selection based on quantity of fiber is accomplished by: size of the animal completeness of cover length of fiber (four inches minimum) diameter of fiber (finer fibers preferred) differences in density (desirable lock formation)
