3.13.1 Explanation of INET (2024)

In breeding the central focus is to produce more highly productive and profitable cows through selection. The Inet rating indicates what can be expected from the progeny in extra net yields per lactation if a certain cow is mated with a certain bull. To give an example, we will mate a bull with an Inet of 400 euro with a cow that has an Inet of 200 euro. A calf resulting from this match is expected to have an Inet of 300 euro, which is 100 euro more than its dam. In other words: the calf is expected to yield a net milk production income per lactation of approximately 100 euro more than its dam. The Inet factors indicate the net yield per kg fat and kg protein provided through breeding when the production per lactation for fat or protein is increased by one kg. Selective breeding that results in an increased production of one kg of fat will yield € 3.00, with € 4.30 for one kg of protein.
