hi everyone.
what are the ingredients that can be used as fillers when in place of protein in ruminant and non-ruminant diet? if we want to prepare a diet with different levels of protein, what are the ingredients we can use as fillers of protein.
these are the normal fillers. can you say differently for ruminants and nonruminats as fibre content is also a concern?
Laying hens were able to compensate for up to 30 % sand in their diet (see attachment). So for that species sand (in a pelleted diet to avoid selection of particles) is suitable as a filler.
Article Sand intake by laying hens and its effect on egg production parameters
By product like olive cake high in fiber. But this is not filler for effective fiber requirement to maintain milk fat content and restrain from sub clinic acidosis for ruminants.
regards sir,
in ruminant nutrition fillers are mostly used for energy but for protein, limited options are there. talking about nonruminant nutrition, very limited knowledge is there. Sand is a new information. if any update is there please add to the list.
poultry research is at its peak. so i think these fillers is a good area of research. i.e . filler for protein and for energy. again in monogastric nutrition we have to think about the fibre content also....
like sand can saw dust be used ???
For poultry, rice broken (param) and grinded soya hulls are considered as good fiiler materials
filler materials are mostly having less or no nutritional potential. but what is the chemical composition of Param and grinded soya hulls,,,
but this is really a new information. thank u Dr Parashuramulu Shanigaram
The answer to your question depends on the purpose of the addition.
Dear Dr Partha,
In the current situation (particularly in India) of exhorbitant feed raw material price, dairy feed industry is seriously looking into potential alternative fillers to economise overall formulation. Few are listed in the enclosed paper. Further, wherever available, ingredients such as tamarind seed husk, babul (Acacia nilotica) pods, food industry by-products (noodles, biscuits, fried snacks etc.) — all @ 2-5% as well as huller rice bran (~10%) and alike could be the optional alternatives. In addition, expensive protein meals can be compensated partly by slow release nitrogen products.
