Breeding Information NICHOLS PURE AND COMPOSITE LINES-All Lines are Black & Polled

|
What is a Nichols Composite Bull? Nichols composites are the result of crossing two or more pure lines in specific crosses to maximize the best traits of the grandparent lines. A composite bull's heterois (cross bred vigor) is transmitted to his offspring. Plus, his calves are more uniform in type, performance, and carcass characteristics than back crossing purebreds. Virtually all poultry, swine and grain genetics are the result of systematic composite breeding.
