| Milking Cows on C Quality Hay / 8MJ Hay |
|
Is this what you would find?
A. If you feed 8MJ hay (or silage) in some "willy nilly" feeders down the lane some cows will eat far too much of this medium quality hay for their own good and some cows will probably miss out. That is unless you allow extended access to the Feeders. Then the only control you have over hay intake is to fill up every cow. (and then clean up their dung!) My guess is that's not exactly what you had in mind. But these are the only choices you have available with uncontrolled feeding programs:
B. If you feed 8 MJ hay (or silage) in the paddock, the worms end up with most of it!! Wastage is a huge problem with good quality hay - A quality (10 MJ) or B quality (9 MJ) - are less wasteful, but with C quality hay, the waste is intolerable. The common reaction to this dilemma is to say:
C. The Result: C quality (8 MJ) hay doesn't fit into most enterprises. Not because it doesn't work, but because farmers do not have a way of feeding it properly, accurately or efficiently. NML The paddock is too wasteful and too much hay is used, Some cows eat as mush as they want and other shyer cows eat way less than this. The "Waste-Not" Fair Go Dairy Feed Pad can feed a
controlled amount of C quality (or any quality) hay or silage and
thus provide a controlled amount of nutrient and a controlled amount of
fibre to every cow twice every day after milking and a ration of grain.
To make some very obvious points:
So why not feed straw?
Sorry � a mouthful isn't 1 kg DM. My estimation is it is only about 1/15th of a kilogram of DM! AND I doubt is 1 kg DM straw (half of which is digested (D-value is about 50%) leaving only 500 gm of dung fibre (read effective or structural fibre) . Perhaps that is the only/ration/source of fibre today (there being no effective fibre in grain and precious little in winter/spring lush green pasture.) Are you sure 500 gm is enough? Remember that a cow's belly is pretty big! We find that tempting cows to eat a controlled amount of 3 kg of oaten hay (with say 8MJ of nutrient) works better - perhaps because it contain (as well as the nutrient) about 2 � times as much (undigested) "Dung Fibre". Seems a pity to be feeding so much nutrient just to ensure enough fibre intake when we have plenty of lush pasture available. BT if the cow can't suck the goodies out of the pasture before it all squirts out the back then the pasture isn't REALLY there! Sometimes we can take 1 kg (expensive grain) from a ration and replace it with a KG of Just Right quality oaten hay - and SELL more COMPONENTS! PLUS 8MJ of nutrient in oaten or fog grass hay is often much more than 8MJ of nutrient in grain so maybe we can even save some money here! It all comes back to CONTROL. If the herd is getting 3kg oaten hay per cow on average, but some cows are getting 67kg and some are getting 0 kg are you sure that is what you want? The average is right, but the "Who Gets What?" question (allocation) is a mess. The "Waste-Not" Fair Go Dairy Feed Pad solves these problems |
