Artificial insemination: there are dilution powder, sperm density meter, microscope, B-ultrasound, car-mounted constant temperature refrigerator and so on.
Heat preservation and maintenance: electric heating plate, oil-fired hot air blower, heating lamp, maternity bed, etc.
Management signs: ear tag pliers, ear tags, marker crayons, ear-missing pliers, pig catcher, etc.
Daily utensils: drinking nozzle, syringe, tooth cutter, tail cutter, drinking bowl, mosquito killer, etc.
Almost all of the above equipment is used in pig farms, and most of them are necessary. I made the following picture specially, which is easy to understand and hard. I hope the landlord will adopt it. Thank you.
