Hybridisation
 
Who uses a terminal or rotational crossbreeding program to increase production and efficiency? While terminal and rotational crosses are common in the beef industry, there seems to be little information on the use of crossbred cattle in the dairy industry. Who has a planned crossbreeding program (beef or dairy) and how has it helped in increasing you production or efficiency?

We can say it is the act or process of mating organisms of different varieties or species to create a hybrid. It is usually used as a term in agriculture or in plant production. really it is usually used to determine the genetic distance between two species. I want to know more about it. If you have more information about it so please share with us.

I think Rotational Crossbreeding programs will definitely increases productivity and efficiency. I have heard from the vet agents that Rotational Crossbreeding programs will increase productivity by 15 to 25% and planned a crossbreeding program for my cows. What is more important in crossbreeding is choosing breeds that work well together. So keep that in mind while deciding to crossbreed your cow

One of the factors in breed selection is choosing a base breed adapted to the environment of your farm/ranch. An example would be the use of Galloway in a cold northern climate, which can then be crossed to another breed to introduce another marketable factor, such as size by using a Continental breed, often the use of two smaller/medium breeds might be used as a "Damline" hybrid, and the Continental used as a terminal cross to maximise heterosis in the final cross all of which are marketed. In southern climates, African Sanga breeds such as Tuli or Mashona are good adapted base breeds, as are the Bos Indicus breeds such as the Brahman, these give a much greated heterosis boost when crossed to Bos Taurus breeds, a Sanga/British breed gives a good F1 Damline with an exeptionally marketable steer, then a Continental can be used for the terminal generation.
