Your transcript is only the beginning. You'll have a better idea of what, where, and, very importantly, who. Some examples are working at the Primate Center, or at the Livestock Pavillion, or in professors' labs . It doesn't hurt, and if your prof isn't necessarily looking for help, you might get a lead on who is. Field work experience is also attainable through an internship .
Many possibilities exist, some with degree credit reward, and some with actual cash stipends.
Look around at department bulletin boards. In the unfortunate circumstance, however, the hiring agency doesn't necessarily agree. Perhaps you don't have exactly what they're looking for. Spread your resume ubiquitously and keep an open mind. It may be necessary to relocate.
