I want to report an inconsistency that I noticed in you data for Indonesia.
According to your statistics, in Indonesia, in 2017 there were 2.18B chickens alive at any time (official data, http://www.fao.org/faostat/en/#data/QA), 167M hens in the egg-laying hen industry (official data, http://www.fao.org/faostat/en/#data/QL), and 2.85B chickens slaughtered for meat (“FAO data based on imputation methodology”, http://www.fao.org/faostat/en/#data/QL). It would follow that the average slaughter age of meat chicken is very approximately 365 × (2.18B-167M) / 2.85B = 257 days, which is much higher than any figure for meat chicken lifespan I’ve seen. According to https://apps.fas.usda.gov/newgainapi/ap ... 3-2017.pdf , meat chicken in Indonesia rarely live beyond 35 days.
My estimation of the 257 days figure is inaccurate because:
*It ignores pre-slaughter mortality. However, the meat chicken pre-slaughter mortality rate in Indonesia seems to be not nearly high enough to explain the discrepancy. According to https://pdf.usaid.gov/pdf_docs/pbaaa047.pdf, it’s 6-7 percent.
* It ignores live exports and imports. According to http://www.fao.org/faostat/en/#data/TA, in 2017, Indonesia imported 5.3M live chickens and exported 7,000. This wouldn’t be enough to explain the discrepancy either.
I don’t see any other explanation that would explain the discrepancy of this size. Hence, I think something is wrong with one of the numbers in your statistics.
Statistical Yearbook of Indonesia 2017 (page 280, https://www.bps.go.id/website/pdf_publi ... f#page=321) claims that there are 1.6B meat chicken alive at any time, which is lower than the figure I estimated from FAOSTAT (2.18B-167M = 2B) but still much higher than we should expect by looking at the slaughter total.
