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 extended 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-voervir-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 . Prices 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 oxen 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 Paper 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! Psalm 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.

Comment:

In the CODE OF CONDUCT of the RPO 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/BestPractices/English.aspx

PRECAUTIONARY MEASURES TO SUPPORT BIO-SECURITY.

Precautionary measures are required to protect the herd against diseases acquired because of external contact. The following categories are of concern:

1. DIRECT LIVESTOCK PURCHASES (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 external 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. PURCHASES FROM SALES OR SPECULATORS

Purchase only in areas which are not in close proximity to scheduled areas

Visually inspect the animals before purchasing for:

* brand marks

* parasite infestation

3. TRANSPORT 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 mixing with the rest of the herd

Process new arrivals within 24 hrs after arrival (unique ID tag brand, dip, dose, vaccinate)

Inspect regularly

5. FEED PURCHASES

Ensure bales of hay are sourced from areas that are not bordering scheduled areas

Purchase 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. EMPLOYEES

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 REPRODUCTION 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.

Sexually 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 external) 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 exposed 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

Precautionary 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.

Prescribed 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.

Monthly report on Livestock and Wildlife isolations for September 2015 from

IDEXX Laboratories supplied by dr. Marijke Henton ( marijke-henton@idexxsa.net

)

Moraxella bovis was isolated from the eyes of cattle. There are three different Moraxella species involved in IBK [Infectious Bovine Keratoconjunctivitis], and Moraxella bovis is the most important.

Moraxella bovoculi can also cause it, but it is of low virulence, as is Moraxella ovis which is usually

isolated from sheep. The vaccine only protects against Moraxella bovis. IBK is exacerbated 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.

Pneumonia in a pig was associated with Pasteurella 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 Preez 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
