Dual Purpose Breeds? Used either as ram or ewe breeds. Columbia Dorset Lincoln Montadale North Country Cheviot Polypay Romney
Ram breeds? Meat type breeds, known for size, growth rate, carcass merit and ease of lambing. Cheviot Hampshire Oxford Shropshire Southdown Suffolk
Characteristics of an Ideal Market Lamb: trim neck and breast muscular arm and forearm wide chest floor deep muscular loin trim firm finish thick upper leg (meaty) legs wide apart Straight top long rump trim front trim middle (belly) bulging leg
Characteristics of an Ideal Breeding Sheep: smooth muscular shoulders/top sex character(feminine, masculine) Breed characteristics large frame deep, wide chest heavy bone deep full heart girth plump muscular leg strong pasterns straight legs square dock long level rump

What are the daily water requirements? Adult sheep: 1-2 Gal Lactating ewes: 2-3 Gal Feeder Lambs: 1-2 Gal Baby lambs: .1-.3 gal
Other random facts about water: Ewes prefer warm water over cold sheep consume 12x more in summer than winter adequate water intake ensure excretion of toxins maintain water above 35 degrees in winter and below 75 in summer winter-warmer water= inc. consumption and inc. milk
Normal Physiological Values of Sheep: T: 102.5 F(102-103.5) Heart Rate: 75 bpm (60-120) R: 20bpm Onset of Puberty: 8 months (4-12) Length of estrous cycle: 17 days (14-20) Gestation period:148 days (140-155)

What are the Primary Parasites of Sheep? Skeep ked Sheep lice Sheep mange Sheep bot flies Wool Maggots Nuisance flies Worms(Round, tape, lung, liver)
Characteristics of Sheep Ked: Wingless fly: mistaken for tick, 1/8" long -cause irritation by sucking blood -on skin level, saliva allergic reaction, causes pruritis and anemia, wool damage from itching
Characteristics of Sheep Lice: primarily biting, less than 1/8" heavy infestations cause wool loss causes pruritis biting-teeth sucking-tubular mouth, causes anemia
Characteristics of bot flies: look like bees deposit larvae in nostrils causes sheep to run around and rub nose on ground irritate sinuses, cause discharge
Characteristics of Mange: microscopic, diagnose via skin scraping, pruritus, wool loss live in skin (dermis)
