When reading the abstract it became apparent that I misinterpreted the prior sentence. This is because producers at that time were still using a “mash-grain” system where they fed scratch grains along with a higher protein mash. Thus the greens were 75% of only the mash… not the entire ration. The actually amount of eggs laid or mash, grain, or forage consumed is not given… therefore one can’t say whether the per animal performance was what one would expect for a particular quality of mash or amount of grain. It doesn’t say whether chickens were able to eat as much grain or mash as they wished (free choice/ad libitum) or whether these were restricted somehow to force the chicken to consume more forage. There is mention that chickens who were confined to their house and had greens brought to them performed better than the ones that were allowed to graze the same crops—which is a very interesting result. Finally it does specify that there was a saving of 36 to 46% by feeding greens over the dry feed cost of the grain-mash system to produce the same eggs. If true this would be significant even at a reduced per animal performance.
I have always read that having chickens on pasture increased feed use and cost due to the fact that the protein and energy in forage was not very digestible by monogastrics, and that the act of running around and scratching used more energy. The common reason given for feeding forage is not to realize feed cost savings but to increase animal welfare and produce a higher quality end product(due to increased taste, omega-3 content and pigmentation). I will follow up by researching all of the sources I’ve read that have stated the fact that forage doesn’t defer costs and update this post… Perhaps I’m wrong and tremendous savings are to be had!
