PhD thesis: Converting wastes to animal feed

I guess you have seen disgusting photos of cows or other animals eating wastes in landfill? It is common picture in developing countries. 

When ruminant animals like cows, sheep etc. eat grasses and other feeds, it is  converted to organic acids like acetic or butyric acids (named VFAs or volatile fatty acids) using rumen bacteria, and then absorbed in the body as energy source for the animals. Eating wastes does the same thing, but not in a controlled way.

Our PhD candidate Milad Parchami investigated converting wastes using anaerobic digestion in a reactor to make VFAs and then give a clear and healthy solution to the animals, and we got interesting results. Now, he nailed his PhD thesis entitled "Bioconversion of Agro-food byproducts to Volatile Fatty Acids: A Sustainable Approach For Ruminant Feed Supplementation" and is going to defend it 16 April. I wish him good luck.

He put these papers in his thesis:

• Membrane bioreactor assisted volatile fatty acids production from agro-industrial residues for ruminant feed application.   
• Production of volatile fatty acids for ruminant feed inclusion from agro-food residues using pilot-scale membrane bioreactor  
• An in vitro evaluation of partial energy replacement in a total mixed ration with volatile fatty acids derived from agro-industrial residues  
• Effect of Agro-Industrial by Products Derived Volatile Fatty Acids on Ruminant Feed In vitro Digestibility  
• Assessment of the impact of biobased volatile fatty acids in ruminant feed using in vitro Rumen Simulation Technique (RUSITEC)  
• Evaluation of the impact of biobased-VFAs addition to lambs’ ration on performance and rumen functionality
