Answer:Farms have changed a lot in the last 50 years. Farms are bigger, livestock are usually raised inside, yields are higher, less manual labor is needed, and it’s not common to see dairy cows, beef cattle, pigs, and poultry on the same farm. Why is this? The answer is simple. Technology.
Think about how much technology has improved medicine & healthcare, communications, and transportation in the last 50 years. The field of agriculture has changed just as much.
Livestock genetics & breeding. Improving livestock breeds is not a new practice. Humans began domesticating animals more than 10,000 years ago. Early farmers selected livestock for their adaption to specific climates and bred them to improve productivity, temperament, and meat, leather, and wool quality. While the practice is not new, the technology used to improve livestock genetics and breed animals has changed dramatically in recent years.
Animal geneticists work to identify elements within genes that can enhance animal growth, health, and ability to utilize nutrients. These genetic advances can increase production while reducing environmental impacts.
It is common for beef cattle and pig farmers to purchase straws of semen from male animals with superior genetics and use artificial insemination to breed females. Embryo transfer is also gaining popularity in the dairy and beef cattle industries.
