Summary of disease report for October 2015 119 Reports from veterinary practices and laboratories were received (Mpumalanga (M) 12; Gauteng (G) 5; Limpopo (L) 6; North West (NW) 10; Free State (FS) 24; KwaZulu-Natal (KZN) 18; Eastern Cape (EC) 13; Western Cape (WC) 15; Northern Cape (NC) 7; Feedlots (FL) 2 and Laboratories (Lab) 7). Reports were also received from practices regarding ostriches, horses and game. These reports as well as the feedlot and laboratory reports are to be seen below the Disease distribution report as reported by veterinarians. I received this newsletter from Barry Symons, retired cattle breeder and beef management consultant (Estcourt) and with his permission I would like to share it with you: B ARRY S N EWSLETTER S UMMER 2015 G l e n b e l l a F a r m B a r r y S y m o n s - 0 8 2 8 9 6 9 0 7 6 age 1 I know it is really tough out there and I have been searching my mind for something positive to tell you. It has taken me some time to pluck up enough courage to write to you, yet I must. What to do during this etended drought which looks as though it is not due to end too soon? Even if it rains today, for many of us there will not be green grass before about the end of November.
Make sure animals have roughage. If you are running short, split herds and open up paddock fences. You can t get smart about grazing systems now. You will be surprized what cattle can find to eat. If you have thorn trees, they will have green leaves and this is a valuable source of fodder. Remember clean water is paramount. Watch out for muddy dams and vleis. Fence off if possible and pipe water to troughs. Consider carting water if necessary. Keep up protein licks. Cows with calves need about 800-1000g/d of crude protein, so try to fulfil as much of this as possible. If you can get a supply of chicken litter then do so and pay whatever they ask. I am not ashamed to tell you that my 50 odd cows are eating 3.5kg litter/day and if this drought lasts any longer then I will up that figure without feeling any guilt. (This topic might be controversial but may be life saving. Remember to vaccinate your animals against botulism at least twice before giving chicken litter! http://landbou.com/kundiges/vra-vir-faffa/hoendermis-as-aanvullende-voer-vir-beeste/ Faffa Malan) Leave your bulls in with the cows for as long as you think it needs to get them into calf. Getting cows in calf is your priority. Remain focused on conception because this year a late calf will be better than no calf. Don t get smart with shortened breeding seasons!! Offloading cattle and marketing. A good friend who knows his stuff advises: Sell any fat cow (C2) NOW. rices are good and supply tight, but that will end before mid- December. Do whatever it takes to get a cow fat, but don t sell her thin (C1). Feeder oen and heifers will be in demand in January again. Look long term and offload timeously. There are a lot of positive things that we perhaps need to take note of during this really awful time. Those of you who have real vleis, i.e. riverine grasslands, need to fence these off from the adjoining veld and use them as valuable sources of fodder in times of drought. Take note that just about the only green in our grasslands is kikuyu grass. Manage these areas separately if they are large enough. Where veld has not been grazed down too short during winter, Themeda triandra (i.e. Red grass) has flowered in spite of there being no rain. There is no tulip in our lands; only holes in the ground where the porcupines have been eating the bulbs. What a pleasure!! The aper bark thorn trees are in full flower and what a sight! Their roots go deep to find water. Like
them, our roots need to stay deep in the Lord to find sustenance for the soul! salm 1 says: They are like trees beside a stream that bear fruit at the right time. Hou die blink kant bo! Best wishes, Barry Symons (Glenbella Nursery glenbella@florasymons.co.za ) Reports of protein, energy and trace mineral deficiencies are increasing. The drought will take its toll on all of us and RuVASA sends their best wishes to all stock farmers during this difficult time. Some areas received sufficient rain and we are thankful with those farmers. Internal parasites The following reports were received from practices regarding internal parasite infestations: Internal parasites M G L N FS KZ EC W NC W N C Roundworms X Resistant roundworms Wireworm X Brown stomach-worm Large-mouthed bowelworm Nodularworm Lungworm Tapeworms arafilaria Liver fluke Conical fluke Cysticercosis (measles) Schistosomiasis (bilharzia) Coccidiosis Be on the alert for signs indicating internal parasite infestation: anaemia, bottle jaw, weight loss and diarrhoea. Animals under stress are more susceptible to parasites. Discuss control and preventative measures with your veterinarian. Eternal parasites The following reports were received from practices regarding eternal parasite infestations: Eternal parasites M G L N W FS KZ N EC W C Blue ticks Resistant blue ticks Heartwater ticks NC
Brown ear-ticks Bont-legged ticks Red-legged ticks aralysis ticks Biting lice Sucking lice Itch mites Sheep scab Mange mites Nuisance flies Midges Blowflies Screw-worm Nasal bot Reports of an increase in tick numbers were received. Tick borne diseases The following tick borne diseases were reported by practices in the provinces: Tick borne diseases M G L N W FS KZ N EC W C African red water Asiatic red water Anaplasmosis Heartwater Lumpy skin disease Corridor disease NC Vaccines are available to control most of these diseases. Discuss preventative measures with your veterinarian. The following tick toicoses were reported by practices in the provinces: Tick toicosis M G L N FS KZ EC W W N C Sweating sickness NC Sweating sickness is caused by the toin secreted by the bont-legged tick. They like to attach in the tail switch and therefore this area should be treated as well. Insect transmittable diseases The following insect transmittable diseases were reported by practices in the provinces:
Insect transmittable diseases M G L N W FS KZ N EC W C Lumpy skin disease Ephemeral fever (Three day stiff sickness) Blue tongue Rift Valley Fever Wesselsbron NC First reports of insect transmittable diseases were received for the new season. The question to you is: Have you already ordered vaccines against these diseases and vaccinated your animals? Venerial diseases The following venereal diseases were reported by practices in the provinces: Venereal diseases M G L N FS KZ EC W NC W N C Trichomonosis Vibriosis izzle disease New cases of trichomonosis are reported every month and this disease is out of hand. Cattle study groups should discuss preventative and control measures with their veterinarians. Farmers are losing millions of Rand due to this disease! Be sure to test bulls regularly for these diseases. Beware when buying in or sharing bulls! Remember female animals may also be infected. Bacterial diseases The following bacterial diseases were reported by practices in the provinces: Bacterial diseases M G L N FS KZ EC W NC W N C Blackquarter Botulism ulpy kidney Lamb dysentery Swelled head Red gut (cattle) Blood gut (sheep) Tetanus Salmonellosis Bovine brucellosis Ovine brucellosis Actinobacillus seminis Bovine tuberculosis

Discuss vaccination programmes with your veterinarian. Fungal diseases The following fungal disease was reported by practices in the provinces: Fungal diseases M G L N FS KZ EC W W N C Ringworm NC
Toicities The following toicities were reported by practices in the provinces: Toicities M G L N FS KZ EC W NC W N C Cardiac glycoside Gifblaar Gousiekte Cestrum (ink berry) Tulip Cynanchum (bobbejaantou) Facial eczema Lantana russic acid Senecio Geeldikkop (duwweltjies) Vermeersiekte Kikuyu Ryegrass Ganskweek Mycotoicosis Diplodiosis Harpuisbos Syringa berries Kraalbos Crotolaria Radish Bracken fern Water contamination Nitrate Urea Snake bite Blue green algae Copper Selenium Zinc araquat hosamine yrethroid Levamizole Fluoride
With the present dry conditions in many parts of the country the only green vegetation is tulip leaves. Young animals graze the leaves and are poisoned and many deaths were reported. The antidote is activated charcoal at 2 gram per kg body weight. http://landbou.com/kundiges/vra-vir-faffa/gif-en-geaktiveerde-houtskool/ Look for ink berry plants which are deadly if eaten by animals. This plant is spread by birds eating the fruits. Always be alert to prevent losses due to toicities. Carefully read labels and packet inserts before using drugs! Nutritional deficiencies The following nutritional deficiencies were reported by practices in the provinces: Deficiencies M G L N W FS KZ N EC W C Energy rotein hosphate Calcium NC Nutritional deficiencies were the most reported on during October. Micro-nutritional deficiencies The following micro-nutritional deficiencies were reported by practices in the provinces: Deficiencies M G L N W FS KZ N EC W C Iodine Copper Zinc Selenium Magnesium Manganese Vitamin A Vitamin B NC There are antagonists such as calcium, iron and sulphur which hamper the uptake of micro-minerals. Have water and soil samples analysed to see what the levels of these antagonists are. Arrange with your veterinarian to have liver samples analysed to determine the status of these micro-minerals in your herd or flock. Multifactorial diseases and other conditions The following conditions were reported by practices in the provinces
Multifactorial diseases and other M G L N FS KZ EC W NC conditions W N C Abortions Stillbirths Abscesses Bladder stones Blindness Bloat Blood gut (sheep) Blue udder Diarrhoea Epididymitis Eye cancer Eye infections Joint ill Lameness/foot problems Lung infection Mastitis Navel ill Red gut (sheep) Trauma Downer Other conditions: rectal prolapses Discuss the origin, treatment and prevention of these diseases with your veterinarian Metabolic diseases The following diseases were reported by practices in the provinces: Metabolic diseases M G L N W FS KZ N EC W C NC Acidosis Displaced abomasum Ketosis Milk fever Due to a lack of energy many ewes with twins contract domsiekte.

In the CODE OF CONDUCT of the RO the following standard operating procedures are documented. The local veterinarian should be your partner to help you achieve the necessary standards. http://www.rpo.co.za/bestractices/english.asp RECAUTIONARY MEASURES TO SUORT BIO-SECURITY. recautionary measures are required to protect the herd against diseases acquired because of eternal contact. The following categories are of concern: 1. DIRECT LIVESTOCK URCHASES (and own animals returning): The following should be verified before importing new animals into the herd: How long animals have resided at the purchase or previous location? Have there been any recent disease outbreaks in the location? Do brand marks clearly confirm ownership? Was a vaccination program followed (need paper or veterinarian proof). What are the local prevalent eternal parasites and the routinely implemented control program? Is a veterinarian supported control program against transmittable diseases followed? Dates and sufficient number of tests for reproductive diseases of both male and female Dates and tests for zoonotic diseases The above should also be verified with the purchaser s own veterinarian. 2. URCHASES FROM SALES OR SECULATORS urchase only in areas which are not in close proimity to scheduled areas Visually inspect the animals before purchasing for: * brand marks * parasite infestation
3. TRANSORT TO THE FARM Use only reputable transporters Has the truck been cleaned and disinfected? Truck to follow the shortest uninterrupted route Truck to take the shortest route to the handling facilities Do not allow the truck personnel to get in contact with the farm herd 4. ARRIVAL ON THE FARM Off-load the livestock to limit stress and to be visually evaluated for any unnatural conditions Isolate them from the farm herd and shared facilities for at least 21 days (quarantine) Retest for diseases of concern if needed, before miing with the rest of the herd rocess new arrivals within 24 hrs after arrival (unique ID tag brand, dip, dose, vaccinate) Inspect regularly 5. FEED URCHASES Ensure bales of hay are sourced from areas that are not bordering scheduled areas urchase feed from reputable dealers only Avoid buying feed in second hand bags Ensure feed trucks are also disinfected and cleaned, especially if also used to transport animals to abattoirs 6. VISITORS Do not allow strangers or their vehicles amongst the livestock Ensure fences are well maintained and preferably jackal and warthog proof 7. EMLOYEES Do not allow the employees to eat in feed stores Supply employees with sufficient ablution facilities Regularly arrange to let employees be medicated for tape worm and have health check-ups Keep record of all employee livestock on the property Treat employee livestock with separate but dedicated health programs Ensure employees understand the reason behind the implemented bio-security measures to help ensure compliance. GENERAL AND RERODUCTION MANAGEMENT Record keeping: All animals are individually identified and recorded. To prove ownership: All animals are marked with the registered brand mark according to the Animal Identification Act, No 6 of 2002. A defined breeding season is the basis of effective management: The breeding season coincides with the rainy season, i.e. the period when nutritive value of the pasture is at its best. Sufficient energy reserves in the herd as measured by condition scoring are vital, especially for effective breeding, and when inadequate the herd is supplemented in consultation with a nutritionist: Condition scoring of bulls and cows are regularly done, particularly at the onset of the breeding season and supplemented if necessary. Bull - cow ratios are maintained: A ratio of 1 to 25 is maintained in every separate herd.
Fertility of breeding bulls: All breeding bulls are tested for mating ability and semen quality before the breeding season. Seually transferable diseases: Sheath washes or scrapes on bulls are performed annually. Diseases that can cause poor conception, abortion or weak calves: Cows are vaccinated against such diseases in consultation with the veterinarian. Breeding success monitored by a veterinarian: Rectal pregnancy or scan diagnosis is done by the veterinarian 8 weeks after the breeding season. Twenty percent of cows or more not pregnant: Further tests are done to determine cause of low pregnancy rate. Culling of non-pregnant cows: Non-pregnant cows are removed from the herd and considered a necessary bonus to supporting herd income. HERD HEALTH AND BIO-SECURITY Maintenance of herd health is key to a successful enterprise: A veterinarian should visit the farm bi-annually at least. Calf mortality before 3 months of age is an important reason for poor weaning percentage: Good management practices are applied to limit early calf deaths. Some diseases and parasites (internal and eternal) are more often encountered in specific areas: Annual vaccinations and a parasite control program should be applied according to regional requirements and in liaison with the veterinarian. Farmers selling weaned calves to feedlots may want to have a market advantage compared to others: A specific vaccination program is applied before weaning for that purpose. Herds may be at risk of being eposed to CA and TB: The herd is tested annually for CA and all heifers are vaccinated against CA between 4 and 8 months of age with an efficient, approved remedy. The herd is tested at least every 5 years for TB recautionary measures are required to prevent diseases being imported into the herd: A quarantine program to keep incoming animals separate is followed. All incoming animals have a suitable certificate of negative test results or are of a certified clean, closed herd. Stock remedies and medicines should be registered, correctly stored and used before the transpire date: All medicines and stock remedies are registered, stored and applied according to prescription. rescribed medicines with a specific application are under the control of the veterinary profession: All prescription medicines are obtained and applied under prescription from a veterinarian. Reports were also received from practices regarding ostriches, horses and game. These reports as well as the feedlot and laboratory reports are to be seen below the Disease distribution report as reported by veterinarians.

Marijke Henton ( marijke-henton@idesa.net ) Moraella bovis was isolated from the eyes of cattle. There are three different Moraella species involved in IBK [Infectious Bovine Keratoconjunctivitis], and Moraella bovis is the most important. Moraella bovoculi can also cause it, but it is of low virulence, as is Moraella ovis which is usually
isolated from sheep. The vaccine only protects against Moraella bovis. IBK is eacerbated by dust and dry winds, both of which were, and are still prevalent. Blue udder in sheep was caused by Staphylococcus aureus and Mannheimia haemolytica. Udder abscesses in a goat were caused by Trueperella pyogenes, as was a pig abscess, a bovine abortion and three cases of pneumonia in cattle. Other causes of bovine pneumonia were Mannheimia haemolytica and Staphylococcus aureus. neumonia in a pig was associated with asteurella multocida, and Streptococcus dysgalactiae caused arthritis in another pig. Salmonella Typhimurium caused enteritis in adult cows, and Salmonella Dublin caused septicaemia in a calf. All the other cases were associated with E. coli ; enteritis in ostriches [2], enteritis, pleuritis, pneumonia and septicaemia in pigs, enteritis in calves [6], enteritis in a lamb, enteritis and bumblefoot in chickens and mastitis in a cow. The only case of interest in wildlife was Cryptococcus in a chronically affected cheetah. Molecular tests will establish whether it is Cryptococcus neoformans or C. gattii. Ordinary biochemical tests are not reliable in this regard. Feedlot report received from Dr. Shaun Morris and Dr. Eben du reez for October 2015 ( edupreez1@telkomsa.net ) Sheep feedlots Dusty conditions again contributed to the incidence of pneumonia in feedlots. Salmonella Typhimurium infection caused some losses. The drought and poor nutrition were the cause of poor and weak lambs arriving at feedlots and they had adaptation problems. Vitamin A and trace element deficiencies in sheep contributed to the presence of eye infections. Wireworm infestations was still at a low level. Acidosis and blood gut occurred in a group of lambs that had been on creep feed. The rumens of these sheep were severely damaged with the result that losses occurred and growth was retarded. Creep feed rations should be formulated with the help of a nutritionist. Circumstances of each farm is unique and must be taken into consideration when this system is used on a farm.
Cattle feed lots Dust contributed to the increase in lung diseases which caused mortalities. Wind contributed to nutritional disturbances, bloat, acidosis and red gut cases occurred. Blackquarter caused sporadic deaths inspite of good vaccination programmes. Lumpy skin disease broke out in feedlots in the Limpopo province and in other feedlots this disease was seen sporadically. At abattoirs a large percentage of lungs were seen with chronic lesions and adhesions and this was due to unfavourable weather conditions. The severe heat conditionscaused stress which depressed the immunity of aspecially the lighter calves but also cattle that had been standing in feedlots for some time Monthly Feedlot report for October 2015 from Dr. Andy Hentzen ( andyvet@mweb.co.za ) Conditions Species Intestinal roundworms O 1 Tapeworms B 2 Liver fluke B 3 Conical fluke B 3 Blue ticks B 2 Biting lice B 3 Sucking lice B 3 Nuisance flies B 2 Midges B,O,C 3 African red water B 2 Asiatic redwater B 2 Anaplasmosis B 2 Vibriosis B 1 Leptospirosis B 1 Blackleg B 2 Red gut B 3 BVD B 2 IBR B 3 Warts B 3 rotein deficiency B 3 Energy deficiency B 3 Vitamin A deficiency B 2 Copper deficiency B 2 Zinc deficiency B 2 Selenium deficiency B 2
