We would like to thank Alex Ashwood of the Australian Brahman Breeders' Association for permission to reproduce this article. Die Raad en Personeel BloemfonteinBeste vriende,Ons het reeds bedank as Lid van die Genootskap maar nog nie ons dank teenoor julle uitgespreek nie.
Dit is bloot as gevolg van die feit dat ek nie weet wat om te sê nie.
Hoe staak mens iets wat jy 20 jaar mee besig was en persone wat al die tyd jou bygestaan het. Hierdie 20 jaar was van die mees opwindenste van ons lewe.
Maar soos die Woord ons leer "Daar is ‘n tyd om klippe bymekaar te maak en om klippe weg te gooi" Ons is nou daar - alles het ‘n tyd. Dit was vir ons n groot plesier en voorreg om met die Brahmanbees betrokke te wees. Om hulle te kon teel, mee te werk en mee te speel.
Ons wil dan nou ook die Genootskap (dit sluit julle almal in) van harte bedank vir al die jare se belangstelling, ondersteuning, goeie raad, vriendelikheid en diens. Ons is dankbaar en sal dit nooit vergeet nie.
Ons wens julle voorspoed toe en mag die Brahman Beestelers- genootskap steeds van krag tot krag gaan.

KI PROJEK • AI PROJECT Hierdie projek vind plaas as gevolg van samewerking tussen die Genootskap, die bul se eienaar, en Taurus. Die Genootskap help met identifisering en bemarking van Brahman bulle wat by die KI stasie moet wees. Die eienaar verskaf die bul, en Taurus het die infra-struktuur om top kwaliteit, siektevrye semen te tap en binne en buite Suid-Afrika te versprei.
Taurus is die enigste geregistreerde uitvoer KI stasie in Suid-Afrika! Hulle het die kundigheid en personeel beskikbaar om die bulle se gesondheid en semen kwaliteit te evalueer, asook die infra-struktuur om die verspreiding te bestuur. Die bulle spandeer ongeveer 3 maande in pre-kwarantyn waar ‘n reeks gesondheidstoetse uitgevoer word, nie net om te verseker dat hulle nie siektes in die KI stasie inbring nie, maar ook omdat daar verskeie geslagsiektes is wat deur bevrore semen oorgedra kan word.
Dit is as gevolg van hierdie siektes dat dit onwettig is om semen, wat nie onder streng kwarantyn toestande getap is nie, te verkoop. Taurus het ook ‘n uitvoerdepartement wat semen uitvoere hanteer na lande waaraan die protokol voldoen.
Die eerste twee bulle waarvan semen beskikbaar is vanuit hierdie projek is die rooi bul BR3391 Mr Bafana (Damview Mr Bafana DVB08129) geteel deur TR Braithwaite van Bergville en grys bul BR3393 Gibson (Jabulisa Sir Gibson SWP094) geteel deur SW Prinsloo van Bethal.

B R A H M A N JoeRNAAl • JouRNAl • oK T oBeR/oCT oBeR 2013 Feed Conversion Ratio (FCR)
In the beef industry FCR has always, and still is, the most popular measure of efficiency used worldwide. It is defined as the units of feed required for one unit gain in body weight. Unfortunately, FCR has strong correlations with size and weight traits. Reduced FCR will lead to an increase in mature size, which in turn will lead to an increase in maintenance requirements of the breeding herd if not included in a proper selection index limiting the genetic change in undesirable traits. Larger animals will not only consume more feed, but might also have reduced reproductive performance if sufficient feed is not available. FCR is also a ratio trait, which makes an improvement in FCR difficult to interpret and does not necessarily indicate an improvement in efficiency. A unit improvement in FCR could be due to either a decrease in feed intake or an increase in weight gain.
Residual Feed Intake (RFI)
The cost of feed is by far the largest expense (55-75% of total costs) in the beef cattle Over the last few decades a promising measure of feed efficiency has sparked industry, with 75% of feed energy used for interest from both researchers and the beef industry. This measure is residual maintenance. Selecting for more efficient feed intake (RFI), also called net feed intake, and is defined as the difference usage of feed could either decrease the between an animal's expected feed intake for its body weight and rate of cost of feeding by decreasing intake without growth, and its actual feed intake. Expected feed intake is calculated by decreasing growth, or increase income by regressing average daily gain against metabolic mid-weight. Some animals increasing growth without increasing intake. consume less feed while still growing at the same rate as those consuming This will in turn increase profit. Efficiency more feed. These animals have low RFI values and are more efficient. The can be improved genetically through the concept of RFI has been proposed for beef cattle in 1963, but has not received choice of breed, use of crossbreeding and much attention until the 1990's. Heritability estimates range between 0.14 and selection within breed. Traits that have 0.58, with most estimates higher than 0.25, showing sufficient genetic variation been used in an attempt to improve feed in beef populations to justify the inclusion of RFI in a selection programme.

(FCR), Kleiber ratio, maintenance efficiency, Unlike FCR, RFI is not correlated to weight and size traits but highly correlated relative growth rate (RGR) and partial with feed intake, and is a linear trait. Selecting for low RFI can therefore efficiency of growth (PEG). It has been said decrease feed intake without reducing growth rate or increasing mature size. that after many years of selection, there has RFI is also not correlated to reproductive traits such as scrotal circumference, been little improvement in true efficiency, pregnancy rates and calving rates. Cows with low RFI values have, however, partly due to increased emphasis on weight been reported to calve 4-5 days later in the calving season, but have shorter traits and inconsistent selection goals. post-partum intervals and less calf deaths (partly due to a lower twinning rate). More efficient cattle should have lower dry Most studies have found no delay in puberty. Carcass fatness is unfavourably matter intakes, less manure production and correlated to RFI, with more efficient animals having less subcutaneous fat. less methane emission, while maintaining Carcasses still have adequate levels of fat and meet market specifications and weights similar to that of less efficient cattle. should therefore still be profitable. There is a method available to calculate RFI It is a challenge to select for animals that in such a way as to eliminate this effect, if the industry desires to do so. These are efficient in feedlots without increasing correlations with RFI show that using this measure as a selection tool has the the mature size of the breeding herd, which ability to improve profitability in more than one segment of the beef industry, will lead to an increase in maintenance cost.

It will therefore increase profit by increasing RFI selects for animals that eat less than expected without growth, while the expense of feed or maintenance cost of increasing size or growth, while not giving any indication of the breeding herd will not be increased. This measure of the size and level of growth, nor preference for large or feed efficiency has been adopted by the American Angus small animals. In other words, small, slow-growing animals can have a favourable RFI. Similarly a large, fast-growing Residual Intake and body weight gain (RIG)

Selection based Many researchers and breeders have hammered on the on RFI does not have to result in small, slow-growing animals dangers of selecting for larger animals, and they have very if ADG or/and height traits are also taken into consideration valid points.

Fertility can decrease and the cost of supplement feed can be high. Smaller animals would suit this environment better as fertility won't be compromised and less (or no) supplement feeding will be required.

The first year I kept only one heifer and a bull, sold the other calves and bought a income per hectare.
top in-calf cow.
"After school I worked for well-known Vryburg stud breeder Jan van Zyl of Kroonvee Brahmans, who taught me the basics of breeding stud cattle. I soon realised I couldn't run my own animals by remote control!" Heinrich farms about 60km north of Vryburg on a spread of three farms, Lovedale, Grandview and Excelsior. He bought Lovedale farm in partnership with his parents Bokkie and Amanda two years ago and runs Brahman, Santa Gertrudis and Simbra studs, a commercial Braford herd and a flock of 50 indigenous speckled goats.
The three farms provide 2 400ha of veld grazing in the Kalahari thornveld of the far North West. Deep, sandy soils are typical of this arid area and the dominant tree species is the camel thorn (Acacia erioloba).
Cattle eat the nutritious pods of this acacia in winter. Annual rainfall is between 450mm and 550mm.
Grazing consists mainly of bushman grass (Aristida uniplumis), black-footed signal grass (Brachiaria nigropedata), Kalahari Sand Quick (Schmidtia pappophoroides) and wool grass (Anthephora pubescens). The wool grass occurs naturally on undisturbed sandy soils and Heinrich, like other farmers in the area, collects seed and plants old maize lands to wool grass.
"It is a hardy species with nutritional value that provides quality roughage," he says.
The Santa Gertrudis and Brahman herds consist of 50 animals each, while there are 30 animals in the Simbra herd and 70 animals in the commercial Braford herd.
