Yang masalah sikit ialah mortality rate. Ada operation yang amik cut off period semasa weaning. Ada yang amik masa umur 6 bulan, ada juga yang amik masa umur anak kambing dah setahun. Ladang aku, amik kira mortality rate semasa umur 6 bulan. Kenapa 6 bulan? Entah..aku pun tak ada reason yang kuat. Tetapi pada masa umur 6 bulan kebanyakan anak kambing dah mula weaned off dan survive dengan 100% meragut. Pada umur 6 bulan threshold bagi coccidiosis, gastrointestinal parasite and other risks of infection dah lepas. Kalau aku amik kira masa umur kambing setahun maka mortality rate is expected to be higher(accidental death mostly-jatuh kolam, hilang).
Acceptable industry level? I have no idea, but in order to be profitable, an operation needs to have a mortality rate of 5% or lower. The figure is derived from a journal from the Internet. Seems legit. But again it depends on the operation type. 5% is acceptable for a fully intensive,closed style system. For a more liberal operation such as semi intensive where input is lower, the acceptable mortality rate should be between 10% to 15%. The higher rate of tolerance is due to lower input required to raise the kids to certain age. Tapi aku punya masalah sekarang, mortality rate untuk kid crop bagi musim hujan dah burst through the ceiling. Around 20%. This is due mostly to the inclement weather. Tapi seperti yang aku kata dulu, this is a challenging period. I have already expected the increase in mortality rate in kids. Hoping for the best.
mortality rate tinggi biasanya sebab induk pun dah banyak tua-tua..yang dara baru belajar nak beranak..
ReplyDeletePengalaman saya...induk tua biasanya akan sebabkan still birth..sebab tulang selangka dah keras..dan tak ada stamina nak push anak keluar. .
DeleteKalaupun anak keluar hidup..induk tua ni tak perform dari segi nak hasilkan susu utk anak..something to do with metabolisme and hormone.
Btw..median age herd saya kat ladang adalah 2.5 years. Takde laa tua sangat kan??
Kalau induk maseh serviceable,..my average is 3 kali beranak, i.e. within 2.5 years also. It is also economical,.. 3+ yrs old mother goats are still marketable.(Es Emdi)
Delete3 kali beranak tu kira bergetah lagi.hehe. utk katjang 2.5 years tu agak lebih kurang dah 4 kali beranak..hehehe..
DeleteApa2 pun..selain dari mengenalpasti mortality rate...kena pastikan juga c.o.d. ke atas ternakan yang matimmsupaya tak repeat mistake.
