The article addresses numbers that are a concern for larger especially industrial livestock operations. It argues that there is a loss of dry matter in fodder around day 6 or 7 compared to seed (apparently it comes back up another 6 or 7 days later). It also argues that in a high-tech hydroponic setup, there is quite a bit of energy outlay to grow the fodder. The loss in dry matter is a concern for those who are looking only at dry matter fed. It's dollars spent for no return on the spreadsheet. What the article does not do is report on any peer-reviewed papers that look at the actual effect of fodder systems on the livestock themselves. I did not see a reference to feed wastage or consumption (do animals eat more of the seeds when they have been turned into fodder than when they are dry?). The article acknowledges that "[COLOR=333333]There is little doubt that sprouts are highly palatable to livestock–witness the relish with which animals consume it in web photos and videos. High moisture feeds are frequently quite palatable. However, we do not have data to suggest that barley ‘forage’ is superior to feeding other forages with similar analyses, or even better than feeding barley directly. The feeding value of the shoot/seed/root mixture may not be better than the initial barley seeds themselves." The last sentence uses the term "may not." They don't know yet.[/COLOR] [COLOR=333333]And I may have missed it, but they are looking at barley. I would not extrapolate that to mean all fodder.[/COLOR] [COLOR=333333]Then there is the paragraph that relates more to my flock.[/COLOR] [COLOR=333333]Quote:[/COLOR] Where Hydroponic Forage May Fit. [COLOR=333333] Although the economics, the yield, and the quality of hydroponic sprouted grain forage are not highly favorable, the concept has a great appeal to those who wish to be more self-sufficient in feed. It may fit for those producers who do not have local sources for hay or forage, or simply want to be more self-sufficient. For small animal producers (rabbits, etc.), this may offer a ready source of palatable feed. Hydroponic sprouted grain may also be an appealing feed which varies the diet for animals fed only hay and grains, although we should caution that the costs must be considered.[/COLOR] [COLOR=333333]End of Quote[/COLOR] [COLOR=333333]My little setup had a one-time cost of $15 for the containers. That's the cost of half a bag of organic layer pellets. Anyone priced greens in winter? Wheat grass sells in a local shop for $6.00 for the amount of fodder I make in one container. I consider that economically favorable. I am feeding this because I want a more varied diet with fresh greens in midwinter for my flock. It is a non-electric setup. No pumps, no artificial light. $0 extra dollars for energy.[/COLOR] I use a window for the solar energy. If you come across a study about health and body condition on animals that have been supplemented with fodder, that would be really neat! Thanks for posting this. It does make a good point about keeping our eyes open regarding the increase in amount of feed. If that were the only reason to use fodder, then one might want to rethink it.
