The intention of any well-managed commercial cattle farm is to provide high-quality beef for the market at a worthwhile stage. Magda du Toit offers rising and aspiring beef cattle farmers with a guideline of the weather they should contemplate when embarking on such a enterprise.
Commercial cattle farming kinds the spine of the beef business in South Africa. Over the previous few years, the demand for good-quality South African beef merchandise, each at dwelling and overseas, has continued on a regular upward curve.
In many instances, cattle farming kinds a part of a diversified farming enterprise, which helps handle manufacturing and market dangers. Moreover, cattle are sometimes saved on marginal soils which are unsuited to planting crops or are used to enrich and add worth to grain manufacturing by permitting the animals to graze crop stubble after harvesting.
Farming in South Africa, nevertheless, comes with an array of challenges. Unpredictable climate and frequent droughts are widespread challenges that farmers must take care of.
This, mixed with fluctuations available on the market and illness administration, signifies that aspiring beef cattle farmers, or producers hoping to diversify into beef manufacturing, should rigorously contemplate the monetary implications of each choice they make, together with what breed to farm and what manufacturing system to implement.
Production techniques
Commercial beef cattle manufacturing techniques will be run underneath intensive, in depth or semi-intensive circumstances. Under an intensive system, cattle are saved in confinement, and have to be supplied with feed and water.
Under in depth circumstances, veld or pure grazing is the principle supply of feed for cattle. The cattle have the liberty to roam outside and have some autonomy over food regimen choice by way of grazing, water consumption, and entry to shelter.
Under semi-intensive techniques, cattle are uncovered to a mixture of intensive and in depth husbandry strategies, both concurrently, or assorted in keeping with adjustments in weather conditions or the physiological state of the cattle.
Regardless of the manufacturing system you select to observe, animal choice, vitamin and well being stay essential elements of any livestock farming operation.
Animal choice and breed alternative
Since livestock farming requires a nice deal of capital with a comparatively low return on funding, the funding in good genetic materials is essential.
Good-quality genetics are important to enhance the productive capabilities of cows and bulls,
in addition to the standard of weaners. Commercial cows are chosen in keeping with their dimension, age, situation, stage of manufacturing and market worth, and have to be largely evaluated on replica statistics.
In an article printed in Farmer’s Weekly in March 2013, Leslie Bergh, then senior researcher on the Agricultural Research Council, identified that there isn’t a ’excellent’ breed. Instead, he mentioned there are higher or worse decisions for particular circumstances and functions.
Your specific farming atmosphere, manufacturing and breeding system, in addition to your market necessities, ought to decide your breed alternative. The breed you in the end choose must also match your out there feed assets and your particular on-farm circumstances.
Moreover, local weather and vegetation zones, the seasons and the terrain are additionally vital components to contemplate when selecting a breed to farm. These components ought to be weighed towards the breed’s traits and temperament, in addition to your beef manufacturing technique, which determines the targets you’ve gotten on your operation.
Other points to take into accounts when selecting a breed are:
- The affordability of breeding animals, particularly bulls. Keep in thoughts that some breeds demand greater costs available on the market.
- Availability and reliability of efficiency check knowledge and breeding values. These are vital for genomic choice.
- Average efficiency of the breed with regard to the traits on your particular circumstances.
- Size of the genetic pool and variation within the breed. Expanding your herd with restricted genetic choices will be problematic in the long term.
- Availability and high quality of breeding bulls in your space.
Since all breeds are totally different when it comes to their marketable traits, a crossbreeding programme may very well be an possibility for a commercial beef farmer. If correctly carried out, crossbreeding could considerably enhance your herd’s productiveness. Moreover, combining the deserves of a number of breeds could give you a aggressive edge available on the market.
When contemplating a crossbreeding programme, consider the traits you need to enhance in your herd, in addition to the heritability of such traits. For occasion, traits akin to replica and longevity have low heritability. As such, these traits reply very slowly to choice, as a giant portion of the variation noticed in them is because of environmental components and non-additive genetic results.
As a commercial beef producer, you might need to give attention to producing calves with low birthweights and better weaning weights.
If you’re utilizing an intensive manufacturing system, you might also need to give attention to enhancing the strolling capability of your animals, for instance. Conformation is vital on this occasion.
Before embarking on a crossbreeding programme, determine what your manufacturing targets are, and choose breeds that can complement one another to provide the best animal on your farm.
Nutrition
The profitability of an animal is set by feed conversion. Cattle require protein, power, water, fats, minerals and nutritional vitamins. The quantities differ in keeping with atmosphere, the animal’s age, time of yr, and manufacturing targets and levels.
As a rule, a beef animal consumes as much as 3kg of feed per day for every 100kg of physique weight. This signifies that a weaned 300kg calf will eat 9kg of high-quality lucerne hay each day to succeed in a median weight of 450kg.
When a younger beef animal reaches between 250kg and 300kg, it’s normally positioned on a high-grain/high-energy ration for 100 to 120 days, or till it reaches slaughter weight.
If you’re working your beef cattle extensively, the situation of the pasture or veld ought to obtain fixed consideration, with the purpose being steady enchancment by way of devoted administration. It is crucial on this case that the veld or pasture offers ample power and vitamins on your grazing animals in order that they continue to be productive.
According to Dr Ockert Einkamerer, senior lecturer in animal science within the Faculty of Natural and Agricultural Sciences on the University of the Free State (UFS), veld administration entails the devoted long-term administration of the out there pasture to enhance veld situation and high quality.
“Veld quality specifically refers to the increase in desirable and nutritious plant species. The focus for grazing management should be on effective pasture utilisation and the dedicated rest thereof to stimulate new growth and translocate nutrients to the roots for growth in the next season. Rest is important, but so are cutting or grazing as a means of getting rid of old growth and stimulating the new. A grazing management system should aim for these goals,” says Einkamerer.
High-quality legume hay, akin to lucerne and clover, normally comprises sufficient protein and carbohydrates for the expansion and upkeep of cattle. Poor-quality feed, akin to grain straw, grass straw or rain-damaged hay, have to be supplemented to extend the animals’ protein or power consumption.
It can be vital that cattle obtain an ample quantity of minerals, as they assist to construct bones and enamel, and contribute to the functioning of proteins and lipids.
These will be offered by way of pure feed or supplementation, the latter of which will be equipped both as a lick or combined into feed.
When buying feed, be certain that you purchase good-quality hay from respected sellers, and make sure that the feed vehicles are disinfected and cleaned, particularly if they’re additionally used to move animals to abattoirs.
Clean water is crucial always. Depending on the climate, and the scale and age of the cattle, an grownup animal will drink between 20ℓ and 70ℓ of water a day. Remember that warmth dramatically will increase water consumption.
Einkamerer emphasises the next when it comes to water and vitamin:
- Always be certain that animals have entry to chill, clear ingesting water always.
- Animals ought to be saved wholesome, as wholesome animals are productive animals. Nutrients can’t be utilised successfully by an animal that’s underneath any stress.
- Make certain that feed troughs all the time include feed. Rumination turns into much less efficient when the microbial inhabitants within the rumen declines, and a hungry animal could overconsume feed, which may trigger metabolic illnesses. It is equally vital to not present an excessive amount of feed, as this may outcome within the animals sorting the feed elements, particularly higher-moisture feeds, and the feed deteriorating in high quality.
- When offering licks, guarantee they’ve the proper salt content material, as this helps to appropriate nutrient consumption to complement any shortages. The appropriate lick ought to be offered for the season, animal requirement, atmosphere and animal response.
- Ensure the animals are checked day by day for situation and potential signs of illness.
- Know the standard and dietary composition of the feed you present to your animals. Formulations and animal response are solely nearly as good because the vitamins offered.
Herd well being and illness prevention
Maintaining herd well being is a key factor for profitable beef manufacturing. Some illnesses in addition to inner and exterior parasites are sometimes prevalent in particular areas. Make certain your animals are vaccinated yearly towards notifiable and prevalent illnesses, and that your parasite management programme is utilized in keeping with regional necessities and in liaison together with your veterinarian’s suggestions.
Your veterinarian ought to go to your farm twice a yr, and it’s essential that herds be examined repeatedly for sure managed and notifiable animal illnesses. For instance, all animals ought to be vaccinated towards lumpy pores and skin illness, Rift Valley fever (RVF), three-day stiff illness, black quarter, botulism and anthrax.
To defend the well being of your herd, see to it that you simply take the required precautionary measures when bringing different cattle onto your farm.
Do not permit any bull that isn’t licensed disease-free onto your farm. According to the Red Meat Producers’ Organisation, the next ought to be verified by a veterinarian earlier than new animals are introduced into your herd:
The period of the interval the animals resided on the buy or earlier location;
Whether there have been any current illness outbreaks within the location;
- Whether the model mark clearly confirms possession;
- Whether a vaccination programme was adopted and whether or not proof of this may be verified by a registered veterinarian;
- What the native prevalent exterior parasites had been on the place of birth, and whether or not a parasite management programme was routinely carried out;
- Whether a veterinarian-supported management programme towards transmittable illnesses was adopted;
- Whether a adequate variety of checks for reproductive illnesses of each female and male animals was performed, and the dates on which these occurred; and
- Whether the cattle had been examined for zoonotic illnesses, and the dates on which these checks had been performed.
When you deliver new animals onto your farm, course of all newcomers inside 24 hours of their arrival and equip every particular person with a distinctive ID tag model.
These animals must also be dipped, dosed, and vaccinated as essential. It is essential that you simply isolate the brand new cattle from your herd, in addition to all shared amenities, for at the least 21 days after introducing them to your farm. This will permit you a while to observe the animals and check for any illnesses of concern.
Even if the animals had been examined earlier than, it’s a good concept to retest them for illnesses prevalent in your space.
According to Leon Kruger, lecturer on animal well being within the Faculty of Natural and Agricultural Sciences at UFS, it isn’t all the time straightforward to observe a set well being administration programme in livestock manufacturing, as the various illnesses affecting livestock are influenced by climate patterns and circumstances.
“The good rain the nation just lately skilled brings a greater incidence of vector-borne illnesses akin to RVF, heartwater and anaplasmosis,“ he explains.
He provides that you might want to adapt your illness management programme to the prevailing environmental circumstances, and factors out the next 5 important points:
Know the situation of your herd.
“A farmer should see and contact the animals by strolling amongst the herd. Only by being in shut proximity to the animals will you be capable of confirm their true standing.“
Know the well being standing of your animals, particularly with regard to illnesses that don’t current with signs.
“Test your female animals for brucellosis at least once every three years and vaccinate heifers between the ages of four and eight months. Brucellosis is a controlled disease and the state veterinarian can assist with this.”
Trust solely laboratory outcomes when buying new animals (don’t take the vendor’s phrase for it!). Kruger says that is significantly vital when shopping for in bulls. Trichomoniasis, for instance, doesn’t current with any signs. If it’s launched onto your farm, your herd’s conception charge will drop considerably, and also you’ll in the end must cull the bull for the reason that prognosis upon therapy of the illness may be very poor.
Biosecurity begins on the farm gate.
“Be alert to the motion of individuals on the farm; this contains employees not residing on the farm. Diseases akin to foot-and-mouth illness are transferred to farms by way of fomites [objects or materials likely to carry infection].“
As far as potential, use target-specific therapy to forestall illnesses from infecting your herd. “Dip [your cattle] when ticks become a problem. Dose when necessary, and vaccinate according to a programme relevant to your specific area. Certain vaccinations, such as those for RVF and brucellosis, are essential. Others must be discussed with your veterinarian.”
Lukas Eksteen, government supervisor of livestock at Bufland Agri close to Mookgophong, Limpopo, says biosecurity have to be a lifestyle.
“Buy animals from respected sellers, and check bulls for trichomoniasis and vibriosis yearly. It’s good apply to implement stringent access-control measures in your farm.“
