Nutritional/Metabolic Problems in Sheep

Young Lambs Enterotoxemia u Clostridium perfringens type C Symptoms u Sudden death in 7-21 day old lambs

Young Lambs.... continued Prevention u Booster dams in late gestation u Vaccinate lambs at 21 days and weaning u Orphan vaccination u Maximum colostrum intake Misdiagnosed-selenium/Vit. E deficiency

GoiterGoiter Symptoms u Enlarged thyroid u Poor wool coat at birth u Low vigor/survival

Goiter..... continued Prevention u Iodized salt u Compensate for goitergens (kale, brassicas, etc.)

Finishing Lambs Enterotoxemia/OvereatingSymptoms u Best doing lambs u Uncoordinated movement u Rapid death

Finishing Lambs... continued Prevention u Vaccination - toxoid u Bunk management u Gradual ration changes u Antibiotics Misdiagnosed-polio and Vit. E/Se deficiency, pneumonia

Urinary Calculi Wether lambs and stud rams Several types-phosphate, calcium, silica Problem-concentrates are low in calcium and high in phosphorous

Urinary Calculi... continued Prevention u Water intake u Salt u Ammonium chloride or sulfate u Add calcium to achieve 1.5:1 ratio to phosphorous u Never add phosphorous

White Muscle/Stiff Lamb Disease Symptoms u Stiff rear legs and arched back u Sudden death u Aspiration Pneumonia u Poor suckling reflex

White Muscle/Stiff Lamb Disease... continued Cause u Deficiency of Vit. E and/or Selenium Note: Selenium is toxic but Vitamin E is not it is also cheap High grain rations reduce Vit. E Newborns only source of E is milk

Results - Serum E lambs ConE-GE-LE-GL 3 days days

Rectal Prolapse Prevention u Longer tail docking u Less dusty feed u Prevent pneumonia u Shearing u Feed some long fiber

PolioencephalomaciaPolioencephalomacia Thiamine deficiency Prevention u Maintain rumen health u Gradual ration changes u Feed some long fiber u Sulpher intake

Copper Toxicosis Breed Susceptibility Mineral interactions-Mo & Su, along with high Zn & Ca along with high Zn & Ca Normal copper, low molybdenum

Copper Toxicosis... continued Prevention u Sheep specific feeds u No additional copper u Feed some Mo Copper & Molybdenum are both toxic

Copper BMPS Sample feed deliveries Monitor feed delivery for appearance and texture Label sample Date, amount, what it was fed to, freeze, store six months Read mineral tag look for sodium molybdate

Pregnancy Toxemia Cause - Excess fat catabolism and ketone accumulation Prevention u Over conditioned ewes u Increased conc. feeding LG u Fetal scans u Pre-lambing shearing

Pregnancy Toxemia... continued Treatment u Propylene glycol u Induced parturition Severe cases usually do not recover

Grass Tetany Hypomagnesia Cause: excess potassium Lactating ewes on lush, spring pasture N fertilization increases risks

Grass Tetany... continued Magnesium oxide in mineral poor palatibility. Sudden death-confirmation by necropsy Stress induced

Milk Fever Ewes vs. Dairy Cows Cause u Calcium deficiency ?? u Stress induced

MIlk Fever... continued Late gestation ewes carrying triplets Symptoms u Depressed, lethargic, recumbent Treatment u Calcium gluconate u Rapid response

Wool Pulling Cause u Inadequate dry matter intake u Small particle size, effective fiber u Low phosphorous intake u Starvation

Wool Pulling... continued Prevention u Maximum 50% concentration ration u Improved feeding technique u Offer some low quality, long forage u Evaluate phosphorous level

Vaginal Prolapses Causes u Overfeeding roughage u Genetics u Short docks u Fat ewes

Vaginal Prolapses... continued Prevention u Feed higher quality roughage in LG u Restrict roughage in ration esp. for ewe lambs u Adequate bunk space u Prevent obesity in ewes u Cull problems

ListeriaListeria

BMP, listeria Corn silage feed adequate amounts correctly stored and harvested Dirt Tub grinder Rotten feed-Feedlot
