Abstract

This study aims to determine the potential for utilizing the waste reproductive organs of productive female goats slaughtered at Malang Goat slaughterhouses. The method used is a case study. The study was conducted at the Malang City Slaughterhouse. The total livestock sample was grouped by puberty and prepubertal age. Results showed that the slaughter rate of male goats reached about 15%, and that of females reached 85%. The slaughter rate of goat aged less than 1 year (prepubertal) is 28,91%. While the livestock puberty rate with an age range of 1 - 1,5 years is about 23%, 1.5 - 2,5 years old is 13%, 2,5 - 3,5 years old is 14 % and 3,5 - 4 years old is 21%. Ovarian reproductive organ waste has the potential to provide oocytes that can be used for research and conservation of genetic material by freezing cells in liquid nitrogen (LN2). Prepubertal ovaries are not feasible for oocyte maturation culture, while pubertal ovaries can isolate oocytes for in vitro culture and frozen storage for conservation. The conclusion is that female goat slaughter at Malang slaughterhouse is dominated by female goats, reaching about 85%. The highest goat slaughter rate aged less than 1 year reached 28%. It is suggested to reduce the number of slaughtered does, and further research is needed on the level of productive does slaughtered.
