According to Barker, there are populations of feral cattle on Tekumel, but only on the other side of the planet from Tsolyanu,and not known to the Five Empires.

You could just replace "Cattle" with "Hma & Hmelu" under the Animal Handling skill, Herding them is a definitely a low status job.
You could I suppose throw in Tsi'il, which are basically six-legged ankylosaurs. They aren't exactly farmed, but they are sometimes kept and raised in very large parks, and then slaughtered for meat. They're slow and passive, but massive and dangerous if they think they are threatened. Catching and killing one would be a big project for a skilled team.

In the Bestiary section, a few of the creatures have their Tsolyáni names in plural forms; these consistently end with -yal. Some of the creatures have a singular Tsolyáni name, but with an English plural translation. An example of the former type is Ninínyal, “the Pygmy Folk” (which would be better described as Ninín, “the Pygmy”); an example of the latter type is Ahoggyá, “the Knobbed Ones” (which would be better described as “the Knobbed One”; its Tsolyáni plural form would be Ahoggyáyal).

In the description of the Ninín is the following text:

As the Tsolyáni proverb puts it: "To bargain with a Ninínyal is to throw away your purse."

This is akin to quoting an English proverb as “A stitches in time saves nine.” The proverb should have “a Ninín” instead of “a Ninínyal”.

Interestingly, The Tsolyáni Language doesn’t have a Tsolyáni entry for “human”. There are three possibilities for it: the first would be to use Básrim, “the Man”. (There also isn’t a generic word for “woman”, so that might analogously be Básrimra.) The second would be to use Tsólu, for which the given translation is “person”. (There are separate words for a noble person and for a non-human person, but it isn’t explicitly noted whether or not Tsólu refers only to human persons.) The third would be to contact the Tékumel Foundation to see if Professor Barker had ever recorded a particular Tsolyáni word for “human”.
