Boran Breed

Genus : - Bos Species : - indicus Breed : - Boran

Current published text states that origins of all domesticated can be traced back to two main centres, Asian (Bos indicus) and the Near East-European (Bos taurus). Due to recent improved technology in the methods of genetic identification and new archaeological findings, there is now believed to be a third origin, which was a native African taurine, centred in the Saharan Belt of Africa (Bos taurus),.

"Genetics studies at the International Livestock Research Institute (ILRI) have shown that the genetic composition of the Kenyan Boran is unique. If the genetic background of the Kenyan Boran is predominantly , the breed also contains taurine background of two separate origins. A European-Near East taurine background of some antiquity and most likely also from recent crossbreeding and an African indigenous taurine background which is not found in any Asian zebu crosses such as Sahiwal or Brahman" (O.Hanotte. See also M.Okomo et al. 1998, J.E.O Rege et al. 2001).

As revealed by O.Hanotte at ILRI, they have shown that the Boran genome contains three distinct genetic influences. Other than the Zebu influence (Bos indicus), there are influences from both the Near East-European Bos Taurus as well as a distinct influence from native African Bos tarus. The predominant influence was however from the Zebu.

"The of the second wave have thoracic humps and started to come into north-east Africa in the 4th century AD, but the major importations date only from the time of the Arab invasions which started in 669 AD." "The Zebu were becoming common in in the 15th century." Ian Mason, (Factors Influencing the World Distribution of Beef Cattle. F.A.O.1974).

From this 'genetic package', came the Borana cattle in , which became the dominant breed type of the region known as the East African Shorthorned Zebu. They are typically the cattle kept by the Borana in Southern Ethiopia and the Somali and Orma tribes of Kenya. From these types came the Boran as adopted by commercial cattlemen in Kenya who developed the breed we see today.

The Boran now found in Zambia, Tanzania, Uganda, Australia and USA originated from genetic exports of Kenyan Boran cattle between the 1970's and 1990's. The breed in Zimbabwe and South Africa came from embryos exported from the excellent facility on Ol Pejeta Ranch at Nanyuki, Kenya, during 1994 and 2000.

The Boran produces high quality beef, utilizing low quality forage. This is substantiated by data from The FAO/UNDP feedlot trial at Lanet in Kenya, where 7,625 Borans and crossbreds were fed between 1968-1973. Similar evidence comes from 1998 trials in Queensland, Australia.

At Lanet, crossbreds between large European breeds and the Boran grew 31% faster on the high concentrate ration (76% concentrate), but had no significant advantage over the pure Boran on the low (33% conc.) and medium (50% conc.) ration. (Kenya Beef Industry Development Project, 1974)

Trials in Nebraska, USA, show that the Boran and its crosses score consistently better than other Zebu breeds for meat tenderness, carcase marbling and rib eye area. Butchers in Kenya prefer Borans and their crosses for these reasons.

Borans are generally more docile and tractable than other Zebu cattle. Large numbers of Boran bulls kept in one herd cause little trouble.

Females are easy to handle, although cows with newborn calves can be naturally aggressive when protecting their offspring.

Boran cattle have a very pronounced herd instinct, making them easily managed in bush country and well suited to cow calf operations.

They always stay together and defend against predators, thus ensuring high calf survival rates.

Two way crossing is the simplest and most effective way of attaining and commercially exploiting hybrid vigour. The all-round genetic package of the Boran cow makes her ideal for producing F1 hybrids. Where pure Borans are available for commercial crossing there remains no purpose in three-way or topcrossing on halfbreds.

 On average cows calve once a year: - potentially 11 months (higher than other indicus breeds)

 Average weight gains per day on grass & feedlot: - Grass = 0.7 kg - 1.0 kg per day depending on grass quality Feedlot = 1.3 kg per day depending on type of cross used (this was found at a recent trial at Marania Farm - Timau where using Boran cross Angus steers & heifers)

 Milk Production from Boran / Friesian F1: -

1st Lactation : - Av = 9.3 kgs per day High= 13.8 kg per day 2nd Lactation : - Av= 10.4 kg per day High = 15.6kg per day 3rd Lactation : - Av= 13.4 kg per day High = 19.5 kg per day
