o Proteins can be evaluated and rated for use by monogastric species by digestibility of the protein and ability to supply specific AA For optimal ruminant utilization, needs can be more complex because of microbial fermentation in the forestomach o Proteins provided by rumen microorganisms provide an adequate supply for animals producing at moderate levels. For young, rapidly growing animals and high-producing dairy cows, this does not appear to be the case o Improved performance has been shown by infusing intact proteins or different AA into the abomasum or duodenum o For animals with higher than normal need for limiting AA, the optimal situation would be to supply adequate N for the rumen microbes With excess dietary protein absorbed in the gut o There is interest among nutritionists, feeders, and milling companies in using protein utilization data to improve protein efficiency by ruminant animals and to allow more efficient use of added NPN Chapter 7- Roughages Plant materials of one kind or another provide dietary CHO for herbi

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
