FOOTNOTES:

==========

(1) Rav Huna maintains that it is permitted to exert effort in preparing food for animals on Shabbos, but it is prohibited to do an act which makes an item into a food (that is, making an inedible item fit for the animal to eat).

(2) Rebbi Yehudah maintains that it is permitted to make an inedible item into food for the animal on Shabbos, but it is prohibited to exert effort to make the food easier to eat or more attractive to the animal.

(3) Even though Rav Huna considers hay tied with two ropes to be food before it is opened, Rebbi Yehudah argues and maintains that it is not considered food and therefore it is permitted to untie it (Rashi). Alternatively, it is permitted because opening bundles of hay tied with two ropes (a) involves no exertion of effort, and also (b) the hay is considered food before it is opened; therefore, everyone agrees that they may be opened on Shabbos (Tosfos DH Rebbi Yehudah).

(4) We have followed the explanation of RASHI. According to the text of the RIF, however, opening the "Zirin" is also prohibited. Bundles tied with rope are already considered to be food before it they are opened, as we see from the words of Rav Huna (with regard to "Peki'in" and "Kifin") and to untie the three ropes is considered exerting extra effort and is prohibited. However, Rebbi Yehudah permits untying "Peki'in" which are tied with only two ropes. Untying two ropes is apparently not considered exerting extra effort (as Tosfos said, see end of footnote 3 above).
