Ang uod ay isang mabuting pinanggagalingan ng protina. Upang makabawas ng gastos sa pagkain, susubukan nating mag-alaga ng earthworms.

Ang earthworm ay tinatawag na hermaphrodite, parehong kasarian ay nasa katawan nito. Sa loob ng 6 na linggo ay mature na ito. Sa loob ng isang buwan ay nakapagpaparami ito ng doble.Kailangan nitong temperatura 25-29 at di naaarawan.

Paraan ng pag-aalaga

Materyales:
lalagyan: hinukayang lupa, or paso, or boxes
earthworms
substrate:

1. Substrate kahit alin dito

manure + ipil-ipil or kakawate (2:1)

rice straw + manure (1:1)

grasses + chicken manure (3:1)

sawdust + ipil-ipil (3:1)

compost / rice straw + corn barn (1:1)

cardboard and paper pulp

(basurang nabubulok, wag lalagyan ng kahit anong uri ng plastic)

Paraan:
1. Pumili ng lugar na di nasisikatan ng araw.
2. Pinuhin o gayatin ang mga bagay na ilalagay dito. Kung mas maliliit mas madaling mabulok.
3.Ilagay sa compost bin at diligan.
4. Takluban ito at hayaan sa loob ng 10-15 araw.
5. Pagkatapos nito puwede ng ilagay ang earthworms.(Mangalap ng earthworms na ilalagay sa compost)
6.Pagkatapos ng 28-35 araw, puwede ng anihin ang mga earthworms. Sa bawat 5 kilong basura(substrate) puwedeng katamtamang pagkain para sa 1 kilong earthworms
7. Diligan din ng manaka-naka ito sa panahon ito upang dumami ang earthworms.
8. Isang Linggo bago mag-ani huwag na itong diligan upang mas madaling mag-ani.
9. Ihiwalay ang malalaki at maliliit na earthworms. Ihiwalay din ang mga breeder worms.
10. Mataba pa ang lupa. puwede rin itong ibenta =).

B. Aquatic animals and terrestrial-based live feeds (CP 40-85%, FCR 10-80)

Aquatic animal feeds and terrestrial-based live feeds are considered to be nutritionally complete. Terrestrial-based live feeds such as earthworms and maggots can be produced on-farm using various organic wastes. Some examples are:

· mollusks such as snails and clams;

· insects such as silkworm larvae (Bombyx mori), soldier fly larvae (Hermetia illucens) and termites (Reticulo termes santonesis and Zootermopsia nevadensis);

· small crustaceans such as wild small shrimp; and

· earthworms and maggot
