A Common sense approach to keeping goats & sheep healthy and profitable Dr. Beth Walker Thanks to Mr. Bruce Lane Basic Rules: •Don’t buy sick animals •Keep _______________ – know which ones get sick and which ones don’t •Follow ____________________ •Don’t believe everything you hear, from someone trying to sell you a goat •Never, ever buy from a _____________________ • Keep in mind…there is as much bad info as there is good info…be selective learners Nutritional Requirements Basic Nutrients • • • • • • Protein Energy Minerals Vitamins Water Requirements will vary according to physiological status of animal Protein • Most common sources • ______________(41%), _______________ (44%), peanut (52%) and sunflower meal • Alfalfa hay (________%) • Prairie hay (________%) • Corn & oats (______%), • Protein is associated with the insides of the plant cells • Older the plant, the more cells have burst, • dried out = higher fiber/protein ratio Goat Nutrition • High protein supplemental feedstuffs: • Gluten feeds, mill feeds and urea (in range blocks) can also be used • Choosing between alternative high protein feedstuffs is largely an economic decision. • Dividing the price of a cwt of feed by its protein content (lb protein/cwt of feed) will yield the cost of 1 lb of protein and facilitate comparisons. Energy • Used for _________________, activity, ___________ maintenance, growth, fat deposition, __________________ • Carbohydrates – 65-75% of dry weight of plants • Crude fiber = estimation of ________ content in a feed • Higher the crude fiber = _____________ the digestible energy • 8% CF = 73% TDN • 24% CF = 49% TDN Energy • High quality hay (alfalfa) can meet or exceed ________ & _____________ needs of mature, non-lactating does • Energy affects PH of rumen • Normal is __________________. To much grain = acidosis • Excessive starch intake can also cause bloat • Must use gradual shifts in diets Energy • Fat • • • • • _________ more energy than carbohydrates No more than ______% of diet Vitamins ____________ Minimizes dust Softens pellets, improves palatability • Dollar unit = __________ is best buy • Low cost • High energy • Be careful!! Nutritional Requirements • • • • • Total dry matter intake: ____________% body weight ______________ are higher in protein than ________ Environment will affect nutrient quality of pasture Roughages higher in _______ than _________ Feed Grains higher in _______ than __________ Forages • Legumes such as ____________, lespedeza and vetch are higher in protein and calcium than non-legumes such as bermudagrass, bluestems, johnsongrass, sudangrass and • Forages consumed by grazing, due to animal selection, are higher quality than hay from the same field. Roughages • Roughages are relatively higher in ____________ than in _____________, while feed grains generally have more ______________ than _______________ • Protein and TDN levels of individual roughages are dependent on several variables • _______________, soil fertility, ________________, harvesting procedures, storage conditions, variety, maturity (age) of the forage crop Flushing • Aids in synchronization of heat • Increases kids born per ewe • Methods • ____________ lb or corn and/or 0.5 lb of protein supplement day/head will usually suffice • Can feed 3x’s per week • Rotate to a fresh pasture • Deworm Missouri Fescue Case Study • Starvation Syndrome What's in your hay?

Soremouth Contagious ecthyma, contagious pustular dermatitis, scabby mouth, orf Soremouth Prevention of Soremouth Orf Club Lamb Fungus Club Lamb Fungus • Why is it be important to you? • It moves from flock to flock or from flock to person through contact. • Sheep/goats can still be contagious without exhibiting external signs of carrying the fungus. • The fungus is thought to be very hardy and can live for years in barns and equipment hidden from direct sunlight waiting for growing conditions to encourage development. Club Lamb Fungus (Ovine Dermatophytosis) • What is it? • First recognized in the 1980's. • Most commonly found in sheep prepared for shows. • It has been called woolrot, lumpy wool, ovine ringworm, and ovine dermatosis. • It is caused by two types of fungus, Microsporum and Trichophyton. Similar fungi cause ringworm in cattle, humans, horses, dogs and cats. • It is contagious to humans. Club Lamb Fungus • Identifying Infected Animals • Lesions can appear anywhere, however, most are found on the head, neck, and back. • Infected skin is thick, raised, red, and "weeping". • Later stages will appear crusty or scaly. • Lesions are small circular spots the size of a dime to fifty cent piece. • Infected spots start small and increase in size over a 4-8 week period. Spots contains lots of infective agents. Club Lamb Fungus • Lesions can be detected 2-4 weeks after infection. • Infections require 8-10 weeks for spontaneous recovery. • Hair re-growth is usually _______________________________________________ • All stages are contagious until hair growth has begun. Club Lamb Fungus • Transmission of the Disease • Most likely occurs at shows or sales. • Is spread by contact with other lambs/goats, humans, pens, or equipment (i.e. shears) • Usually enters through scrapes or cuts. * easily transmitted by contaminated clippers, blankets, combs, bedding, bunks, and pens. Contact of lambs at weigh-ins, "Jack-Pot" shows, etc., along with loss of natural protection because of close clipping, washing, and covering with blankets probably contributes significantly to the incidence and severity of the disease. Club Lamb Fungus • Prevention • • • • • • • • • • • Proper nutrition and care. Keep sheep and barns as dry as possible. Avoid nicks and cuts when shearing. Disinfect equipment (shearing equipment, etc.) with a commercial fungicide. Wash and shear show lambs as little as possible. Use protective gloves when handling infected sheep/goats. Quarantine new arrivals before mixing with flock. Separate infected from non-infected goats/sheep. Disinfect pens as needed. Show equipment such as like blankets towels and haltersshould be used on only one goat. Persons handling infected or exposed animals should wear rubber gloves and clothing with long sleeves. Wash thoroughly after handling animals and wash clothes thoroughly. Animals with active lesions should be removed from shows. • Vaccine? (one exists for cats) Club Lamb Fungus • Environmental control Captan, (available at garden centers) One pound in 15-20 gallons of water to spray down the premises and soak clippers, brushes, cards, etc…has been recommended. Veterinarians must be careful in recommending the use of this product anyway other than the label. There is no leeway for extra-label use in products controlled by the EPA. (AMDUCA does not apply) Bleach, and other agents with anti-fungal activity may be used Club Lamb Fungus • Treatment • Not enough data to currently recommend a particular treatment. Effective systemic anti-fungals have been reported to decrease the length of disease from 8-16 weeks down to 3 weeks. • Fulvicin (griseofulvin,) in lambs is thought to be effective in treating CLF. No efficacy trials have been conducted, however, anecdotal reports have been positive. • ThiabendizoleTM Club Lamb Fungus (TBZ) has been used. A veterinary-labeled product is no longer available, however a human product is still available. 1 lb. of petrolatum jelly 20 grams of ThiabendizoleTM 15 ml isopropyl alcohol Liquefy the vaseline, stir in powder, and add the alcohol. Makes approx. 4% ointment. Club Lamb Fungus • • • • • • • Over the counter human topical products such as 1% Chlortromazole, Tinactin TM, may be effective CaptanTM has been used with some success The efficacy of various fungicidal shampoos is questionable due to the short exposure time on the skin Iodine compounds (iodine based soaps, etc.) have not shown to be very effective against other dermatophytes. However these compounds may reduce the infectivity of the lesions. Commercial Products are on the market Moisturizing products Pipestone Recommendation: keep an antifungal spray on the lambs following each show to help prevent the spread of "Club Lamb Fungus." *Recommend using Nolvasan or a similar product prior to and following any contact with other lambs or exposure to show blankets or equipment used on other lambs. Lambs that develop the fungus lesions are usually done with their show career because of the long recovery period following a fungal infection. Club Lamb Fungus Regulations require a safe and reasonable withdrawal time be established before a drug can be prescribed extra-label. Currently no data in sheep is available, so a withdrawal time cannot be established. Pharmacokinetic data in other species vary greatly; consequently extrapolation of pharmacokinetic curves to sheep is not possible. Scrapie Scrapie Scrapie symptoms Scrapie Why do we need to eradicate scrapie? Transmissible Spongiform Encephalopathies (TSEs) TSE • • • • Always fatal, degenerative diseases of the central nervous system. Transmissible Creates spongy holes in brain. Theory: can TSE’s cross the species barrier????? Controlling and Eradicating Scrapie Third Eyelid Test • Live animal test • Test lymph tissue in third eye lid for presence of scrapie agent. • Difficult to do More Info on Scrapie? Scrapie Identification Program (Sheep) • The following animals need ear tags: All sheep 18 months and older All breeding sheep All scrapie exposed, suspect, test-positive, and high risk animals Breeding goats, except low-risk commercial goats All sheep and goats for exhibition * Always check ahead with shows and exhibitions for specific health requirements ** Check with Federal Veterinarians office in Jefferson City, MO for rule clarification or to obtain official program ear tags (573) 636-3116 Scrapie Identification Program (Goats) • Commercial low risk goats may be moved interstate commerce without identification. Commercial low risk goats are: • • • • • Raised for fiber and meat Not registered or exhibited Have not been in contact with sheep Not scrapie positive, high risk, or exposed animals Not from an infected or source herd * Sexually intact goats used for exhibitions, demonstrations, petting zoos, or that are registered will need individual I.D. numbers and have health certificates to cross state lines. Goats with legible registry tattoos accompanied by a copy of their registry certificate do not require additional identification.

High abortion rates have been recorded (up to 70 percent). Two strains - Campylobacter jejuni or Campylobacter fetus. Ewes are infected by oral ingestion. Incubation period from the time of infection and abortion is only two weeks. Vaccination can be effective in the face of an outbreak. Feeding of antibiotics (tetracyclines) has been shown to be effective. Less effective if jejuni strain. Disease spread can be prevented by isolating aborting ewes, disposal of fetus and membranes and disinfecting affected area. Infected ewes usually recover after aborting and are immune to re-infection. A vaccine is available for Vibrio. Vibrio vaccines – buy those that contain both intestinalis and jejuni strains. Enzootic Abortion (EAE) (Chlamydia psittici) • • • • • • Chlamydia is the most common cause of abortion Transmitted from aborting does to susceptible individuals Abortion during the last month of pregnancy Birth of kids that die shortly after birth May cause pneumonia in young kids Chlamydia abortions can usually be stopped or reduced by treating entire flock with tetracycline. High levels may be required in problem flocks • Vaccine is available Toxoplasmosis (toxoplasma gondii) • • • • • • • • • Causes abortion in ewes Cause is a protozoan that causes coccidiosis in cats Follows ingestion of feed or water contaminated with oocyte-laden cat feces. The organism migrates to the placenta and fetus(es) causing their death and expulsion. Ewes abort during last month of pregnancy or give birth to dead or weak lambs that usually die from starvation. Infection in the first two months of gestation results in embryonic death and reabsorption. Evidence that Rumensin® and Deccox® will partially prevent toxoplasmosis in pregnant ewes. Limiting cat populations and preventing contamination of sheep feed and water with cat feces helps prevent disease. There is no vaccine available in the U.S. for toxoplasmosis. Pneumonia (Pasteurella haemolytica or Pasteurella multocida) • • • • • • • A respiratory complex with no single agent being solely responsible for the disease Affected animals become depressed and go off feed They may cough and show some respiratory distress Temperatures usually over 104°F The disease may be acute with sudden deaths or take several days. Pneumonia is treated with antibiotics. One of the most common causes of death in newborns Polioencephalomylacia • Also called polio • Caused by a _________________________________________ deficiency • Since the rumen manufactures B vitamins, polio is not caused by insufficient thiamine, but rather the ability to utilize it • Most common symptom is blindness and star gazing • Most commonly occurs in kids on high concentrate diets • Polio can also occur in goats of all ages on pasture • Goats respond well to injections of thiamine hydrochloride Copper Toxicity • • • _____________________________ can be fed diets with copper Copper is closely related to molybdenum and toxicity occurs when dietary ratio of copper to molybdenum increases to about ____________________________ When consumed over a long period of time excess copper is stored in the liver. No damage occurs until a toxic level is reached at which time there is a hemolytic crisis with destruction of red blood cells. • • • • Affected animals suddenly go off feed and become weak. An examination of their mucous membranes and white skin will reveal a yellowish brown color. Their urine will be a red-brown color due to hemoglobin in the urine. Treatment of copper poisoning is based on inactivating the copper with ____________________ and sulfate. * Prevention: Be careful what you feed! Vaginal Prolapses • • • Most commonly observed during ____________________ month of pregnancy or shortly after lambing Suggested causes include genetics, hormonal/metabolic imbalances, overfat/overthin body condition, bulky feeds, lack of exercise, dystocia in previous pregnancies, increased abdominal pressure and fetal burden. Prolapses often recur in subsequent pregnancies Vaginal Prolapse Repair • • Exposed vagina of doe should be washed with soapy disinfectant solution and placed back into doe. After above, typical repair techniques are: 1. Harness (preferred by many veteran producers) 2. Retainer "spoon" can be inserted and secured in the doe to prevent further prolapsing. 3. In a doe that has lambed, sutures maybe used to secure the prolapse or the harness may be put back on the doe for a couple of weeks post lambing. * Affected doesand their offspring should probably not be kept in the flock for breeding animals due to the possibly hereditary nature of the problem. Vaginal Prolapse Harness Uterine Prolapse Uterine Prolapse • • • • • • • • • A uterine prolapse is when the womb is turned inside out and pushed through the birth canal by the abdominal strainings of the doe Can occur prior to kidding and immediately after lambing and is a life-threatening situation C-section and put the doe down Must be manually forced back into the doe The uterus should be cleaned with a warm, soapy, disinfectant solution prior to replacement and should be replaced before the tissues become dry or chilled Placing the does rear legs up over a panel or gate may reduce resistance and make it easier to insert the uterus back in the doe Sutures are necessary to keep the uterus in place. Older does are more commonly affected Cull affected does Mastitis Mastitis • • • • • Also called ________________________________________________________ Staphylococcus aureus and Pasteurella hemolytica Two types of mastitis: acute and chronic Affected doe may be reluctant to ______________________________ May hold up one rear foot • • • • • • May not permit her kids to nurse Does with chronic mastitis often go undetected. Mastitis is treated with antibiotics and systemic antibiotics There is no vaccine for mastitis. Prevented by good management and sanitation. Observe and handle udders Mastitis • Prevention • Peak milk production – 45 days • Problems most associated with high milking does and when kids are early weaned – 60 days • Some will wean male kids at 3 months and females at 4 months • Decrease fed to lactating does 2 weeks prior to kidding • Pen does and hold off of food and water 24 hours • Feed roughage sparingly until time which they have dried up • Relieve pressure on those that are still lactating Mastitis • Prevention • • • • • • Bedding in drop pens, mixing pens and lambing jugs should be clean and dry. There should be good drainage around the barn and lots. Animals should not be overcrowded. The incidence of mastitis is greater in closely confined flocks. Cull does with lumpy udders Could have a genetic component so might be wise to cull daughters Mastitis • Treatment • • • • Milk out affected side Get all the “cheesy” material out Put doe on antibiotic Visit with vet for Urinary Calculi • • • • • • • Also called ____________________________________________________________ Metabolic disease of wethers and rams characterized by the formation of calculi (stones) within the urinary tract Blockage of the urethra by calculi causes retention of urine, abdominal pain, distention and rupture of the urethra or bladder The most common cause of urinary calculi is feeding rations with high phosphorus levels. The ratio of calcium to phosphorus in the ration should be at least ___________________________________ Adding feed grade limestone to rations may be necessary addition of ammonium chloride to the ration will aid in preventing urinary calculi. It is also important that animals have an ample supply of clean, potable water. • The addition of salt to the ration will increase water intake and decrease stone formation Urinary Calculi Pinkeye • Also called infectious __________________________________ • Highly contagious disease affecting the eyes of sheep • May result from many different infective agents: _______________________________ certain viruses, and mycoplasma • The disease will usually complete its course in three weeks in individual sheep • The use of eye medications containing antibiotics may be helpful in individual cases • There are no effective vaccines available • The agent that causes pinkeye in sheep and goats is different from the one that causes it in cattle Pinkeye What’s in your medicine cabinet?
