Cobb has been a major role player in the broiler industry for over 100 years. Roughly half of all the chicken processed globally is Cobb.


1916 - The Beginning
Cobb started off with modest beginnings in Massachusetts USA in 1916.
Since then, the company has developed into one of the world's largest and most established broiler breeder companies – wholly owned by Tyson Foods in the US. Currently the breed is used in chicken production in over 60 countries.


1997 - The Rainbow Alliance
In South Africa, Rainbow Farms' relationship with Cobb began in 1997 when they first imported grandparent stock. Over time, and because of the symbiotic and inherent strengths of the relationship, Rainbow moved to utilising the breed completely across all three production regions.
This was followed by the establishment of a forward alliance - that of being the sole representative in South Africa and so ‘Cobb South Africa' was established.
This investment has provided benefits to the entire South African poultry industry and provided access to considerable international technical support in the areas of breeding, broiler, nutrition, flock health, environmental control, processing and planning.


2000 - COBB South Africa
Cobb South Africa operates from two large, modern grandparent units. The first is at Carolina, in the Mpumalanga Province, where our new breeder and hatchery complex was inaugurated in late 2000. Due to the demand for the Cobb500 product, further investments were made and at the end of 2007 a second production unit was opened at Mpongo Park, near East London. We now have two strategically positioned production units. They are strategic for supply and biological risk management in the event of a major disease outbreak.
We aim to offer a better-quality breed of chicken to local poultry farmers, and our success in this endeavour has been unparalleled. It can largely be attributed to the high performance and consistency of the Cobb breed, which translates into exceptional meat yield, excellent appearance, uniformity and taste quality.
The Cobb breed now has over 40% market share in South Africa.
