[Elements vary by font when used within other glyphs as an element] Older font depictions and the Used-In glyphs point to these elements as「meat and child.」Interestingly, 育 with the same pronunciation and meanings uses the same elements as in this glyph, but drawn inverted. Some suggest may refer to a child having TRUST that a parent will provide SUSTENANCE, NOURISHMENT.
　Modern fonts use「hand reaching down」to grab a「child」as if to inspire within the child feelings of TRUST for a parent who will always reach down to care for the child and pluck him or her from trouble when needed. Also used are「repeatedly dazzling a child」that may speak for itself, and,「repeatedly stuff flying out with spermatozoa」that describes male gametes ENCASING an EGG while attempting fertilization: the ancient Chinese possessed powerful magnifying devices, see 孑 for details.
　BROODING eggs or ENCASING chicks. Brooding means to 'warm with one's own body heat, to encase with meat.'
　All are possibilities, but also perhaps is a「hand reaching down to grab child」「repeatedly dazzle a child」「repeatedly stuff flying out with spermatozoa」for other more obvious reasons, knowing that「child meat」(generally) can be TRUSTED to not have any transmissible diseases or infections:「In traditional Chinese medicine, there has never been a mental disease called pedophilia (or an equivalent term), or homosexuality, or most of the other so-called sexual variations for that matter. …Children are usually described as natural sexual beings and erotic stimulation and sex-play are seen as beneficial to their healthy development.」

　「Like humans but unlike chimps and most other animals, bonobos separate sex from reproduction. They seem to treat sex as a pleasurable activity, and they rely on it as a sort of social glue, to make or break all sorts of relationships. 'Ancestral humans behaved like this,' proposes Frans de Waal, an ethologist at the Yerkes Regional Primate Research Center at Emory University. 'Later, when we developed the family system, the use of sex for this sort of purpose became more limited, mainly occurring within families [i.e., incest]. A lot of the things we see, like pedophilia and homosexuality, may be leftovers that some now consider unacceptable in our particular society.' 」

　…yet.「Grabbing child meat」or「grabbing meat, with ejaculation」for use to ENCASE a penis in hot meat was common in China when the meat belonged to a child, a sex slave, and/or a service provider (in any combination), 'the chicks' (noting that there are no 'bird' elements in this glyph):
　「The [foot-binding] process was started before the arch of the foot had a chance to develop fully, usually between the ages of 2 and 5. …Qing Dynasty sex manuals listed 48 different ways of playing with women's bound feet.」

　Perhaps,「meat maggot」literally as a maggot (a larva or 'child fly') ENCASED, feeding and NOURISHING itself…maggots (housefly「eggs」) feed by sucking juices emitted from putrid meat. Perhaps「hand reaching down」to grab some「maggots」in order to ENCASE and clean putrid flesh from a wound and TRUSTING that no other tissue will be consumed, known as maggot debridement therapy (MDT). Maggots eat rotting meat first and not healthy flesh, unless healthy meat is all that remains (see 享).
