These are generalisations that are just too broad, some manure and some
straw has too many seeds. Chicken manure contains no viable seeds. Some
straw is almost pure stalks from after the grain was harvested and contains
no seeds or almost no seeds. Even cow and horse manure can have no
significant viable seeds depending on what the beasts were fed on, the time
of year etc. If you want to be able to take advantage of all possble
sources of fertiliser and mulch you have to know your shit!
As fresh manure is often too strong to apply directly hot composting with
other material (eg manure plus straw plus garden clippings) will reduce its
strength and kill seeds if it has any.
my favourite mulches are the green types ie.,. spoilt lucerne hay &
pasture grass hay, i use these all the time and never need to
fertilise, never weed mygardens and minimal watering, but then i lay
it around 8 to 10"s thick.
