General Interpretation:

The sire has a slightly longer gestation, significantly lower birth weight, and below-average growth rates at different stages. However, he compensates with a significantly heavier mature cow weight, larger eye muscle area, higher retail beef yield, and above-average genetic potential in several indices, including Wagyu Breeder Index, Self Replacing Index, and Fullblood Terminal Index. His marbling is moderate but with below-average marbling fineness.

The dam, on the other hand, has a significantly shorter gestation, lower birth weight, and average growth rates at different stages. She has a lighter mature cow weight, average milk production, and an average level of most traits, including scrotal size, carcass weight, and rump fat. Her marbling is low, but she shows above-average genetic potential in the F1 Terminal Index.

The inbreeding coefficient of 7% suggests a relatively high level of genetic similarity within this mating.
