[QUOTE="4CTophand, post: 611862, member: 9140"] [b]Good Topic Dun Cool season Perennial Kentucky 31 is a nightmare--- first used on the IH systen was great for holding the land together and overpasses. It is true that KY 31 has toxic endophytes and you just cant let it head out..... Some ranchers will say a cow will graze the leafs below and wont eat the stem (heads) this is not true. I will explain in a minute. If you are stuck with an established stand I would graze it down to the 3 inch mark but not below--- because as you should know the brown stomach worm ((which is really a nematode) is the most costly parasite in the cattle business today although mature cows are less susceptible to it than are their calves) are always found in the lower parts of the grass plant ~2 inch mark The life cycle of this parasite is as follows --- eggs shed in feces at day 0 ; in its' infective larval stage by day 7 ; cows ingest infective larvae when on grass below the 3 inch mark and re-infect themselves with the parasite cutting your production. This rule of thumb will help you decide how many acres your MIG paddocks should really be. Other negative facts about Fescue are that when cattle eat the toxic head it causes many bad things-- like cutting off blood flow to the extremities (this is why you see cattle missing tails that are on fescue pastures). Other problems include calcification of the Uterus-and you will probably think she is just Cystic and give her some Cystorelin-- but she will never breed again-- fact. Yet still other bad experiences with fescue is an increase in Pink Eye in cows and calves and last but not least stockers being Grass-finished on Fescue KY 31 have the nastiest smelling beef carcasses and taste is pretty bad..... Other Issues about KY 31 Fescue is that TDN is in the Toilet. and CP isn't that great either-- many times of the year cattle can't meet their nutritional requrements on Fescue alone. As for optimum growing temperatures for KY 31; normally it has a bi-modal growth pattern depending on where you live--I think you ar in Ark, for instance, under 35 degrees it will not be dormant, but semi dormant not really actively growing growing best in the Spring and dormant during the hot summer months above 80 degrees (when endophytes are toxic) and after the heat of the Summer months have passed it will again have decent growth until cold weather yet returns. Most people I know that are stuck with Fescue have either killed it and planted Orchardgrass or no-till seeded some clover in there to help improve the CP and TDN available to their cattle. they do have a so-called endophyte free Fescue you can read up on Max Q, but the stands seem to have a poor survival rate due to the lack of this toxic endophyte. All I know to do with KY 31 is graze it to 3 inches drag your pastures after each grazing event and dont worry you cant kill it by grazing even if you wanted to T [/b] [/QUOTE]
