What fuel would you put in your Ferrari?

摘要

Advances in pig genetics can only be compared to advances in the car industry. Precision cars, such as Ferraris, require precision fuel to maximise performance. Genetics have moved forward at a considerable pace over the past three decades, with the modern sow able to achieve over 30 piglets per sow per year. But whilst nutrition has moved forward to meet the demands of hyperprolific animals in terms of energy and amino acid components of sow nutrient requirements, very little research has focused ontrace minerals. The latest research on inorganic minerals currently widely used is over three decades old. If we cast our minds back to the sow 30 years ago, she not only looked completely different, but compared to today was a totally different biological animal.
