There have been confusion in the modern broiler chicken market as to which is the best; COBB, ROSS or ARBOR ACRE (AA)

Before any analysis, I want us to understand the great-grand-parents (Pedigree) of broiler chickens; Crosses of CORNISH GIANT(male)  PLYMOUTH ROCK(female).

In most cases, both are white to continue the lineage of white feather trait. The Cornish males are known to be broad breasted and tall, while the Rock females are known to be fast growers with evenly deposited muscle mass. The cross of both gave a superb result.

BROILER CHICKENS, BREEDERS AND PARENTS

COBB® is the first brand name company to start the crossing research of chicken for meat as far back as 1916 in U.S, is known as the oldest company of broilers pedigree. Their history of broiler chicken production serial as Cobb, Avian, Sasso, Cobbsasso, Cobb500, Cobb700.

AVIAGEN® is known as U.S Company that rose up after Cobb to become the world largest research and supply of broilers pedigree having branches in America and Europe with several brand franchises. They supply pedigree to U.S based Ross®, U.K and European based Arbor Acre®, Hubbard® and Indian River® in Europe and Asia.

Key Points:

All the modern broiler strains are just names from international companies that sell broilers breeders all over the world.

COMMON BROILER CHICKEN STRAINS IN NIGERIA: Efficiency and Productivity.

COBB 500: Grows fast and tall, evenly distributed muscle mass, less fat, FCR 1.4 – 1.65 in 6 weeks, weight improvement when ME is above 3000 KCal at finisher stage. Looks like the Marshall but Marshall has bigger leg bone mass.

COBB700: Is the latest and improved, scarce in Nigeria.

ROSS 308: Grows faster, more breast muscles, less fat, poorer FCR 1.7 – 2.2 in 6 weeks, no significant weight improvement above ME 3000 KCal, best result in a closed cold system or during winter, lowest immunity/survivability according to research and comparison.

ROSS 708: Is the improved strain but not yet in Nigeria.

ROSS 808: Is still under research

ARBOR ACRE (AA): Grows fast, evenly distributed muscle mass, less fat, FCR 1.6 – 1.9 in 6 weeks, ME range from 2900 KCal and above is able to give efficient result, better warm climate performance in comparison, highest immunity/survivability according to research in comparison.

ARBOR ACRE plus (AA+): Is the currently improved strain, scarce in Nigeria.

CONCLUSION

In the real sense from the information above, it now depends on individual farmer preference to choose which strain best fits for his/her farm management either in growth rate, tallness, FCR, ME, or survivability.

In general, all the broiler strains give equivalent weight at 6 weks with Ross on increased margin but poorer FCR and survivability in modern broilers comparison.
