Many economic traits of beef cattle, such as body weight, body size, growth rate, and lean meat production, are basically quantitative traits. Under the control of micro-genes, these genes can affect the phenotypic value of economic traits and have additive effects. It is called additive gene action (effect). High-yielding genes can accumulate by licking and can be mutated and increased in offspring.
Different traits of beef cattle have different genetic trends. The heritability (h2) is used to measure the heritability. Studies have shown that different traits of beef cattle have different heritability. The heritability is mainly due to the additive effect, the traits related to the quality of livestock products that are formed in the later stages of life, and the traits that are easily influenced by the environment, the traits that are formed early in life, and the fecundity, viability, Adaptability-related traits have less heritability; other extruded traits have moderate heritability.
Of the differences in the live weight of beef calves at birth, 40% are due to genetic causes.
