“The purpose of slave breeding was to produce new slaves without incurring the cost of purchase, to fill labor shortages caused by the termination of the Atlantic slave trade, and to attempt to improve the health and productivity of slaves. Slave breeding was condoned in the South because slaves were considered to be subhuman chattel, and were not entitled to the same rights accorded to free persons.”
