How does one get south of I-35?
Yelp you don't get to South Texas much. 35 stops in Laredo
Anyway most of STX is F1 type crosses. The love big ears.
I don't spend any time in Mexico, either, which is technically south of I-35. But no matter where F-1 cattle are, they are still psycho.
I've worked and gather just about every Prominent breed in Texas. Worked several barns in Texas.
It's all on who raises them and how they are handled. Gather only once a year with helo's and 4wheelers you have wild cattle. From a kill you stand point, I won't get in a pen or step with in range of a Holstein bull. And I sure as hell will never turn my back to one no matter the distance. Now from a bred does that make Holsteins crazy... the obvious anwser is no.
You can find loose head genes in horse way more then cattle. Whole different level of breeding.
The ones I worked were always eased around. No pressure, no pushing, just ease if they will. Yes the mamas were the most protective cows I've ever seen. Didn't really worry about coyotes with them. But get the yearlings, and younger, in a 1 acre pen, and the rodeo was on, though we tried to calm it.
An aquatance of mine always raised polled Hereford, Angus, or black baldies. Once he got in the F-1's, he segregated them to another pasture, and it was called "The Psych Ward".
