The objective of grading up is to produce progenies having 50 to 75% of exotic blood followed by inter-breeding and selection to fix desired characters in new breeds containing exotic inheritance between 3/8 and 5/8. Plagiarism Prevention 4. 5. mating of related individuals often results in a change in the mean of a trait. Linebreeding is a ratchet mechanism for holding any gains already made by selection, while attempting to make further gains.

"Budgeting for Agricultural Decision Making." 2. Their production level has been fixed at 2,000 kg and 2,500 kg, respectively. Production of animal differs even among individuals within a breed. Disadvantages. A hybrid is crossed back to one of its pure bred parents. Therefore, when selection becomes ineffective, other breeding techniques will have to be employed. (Prasad and Singh, 1983). Producers can normally stock gestating sows at 4 to 6 sows per acre and growing hogs at 10 to 12 hogs per acre. Grading represents a practical approach to the problem in that it generally employs less detailed methods than some that are available. Then the principle of the method involves counting the average number of organisms per microscopic field. of Grading Normally, breeds are chosen that have complementary traits that will enhance the offsprings economic value. 2. An example of Forward Grazing can be seen in Figure 5.
