Cím:	Reproductive failure removal among nurse sows / Joab Malanda Osotsi, Gabriella Novotni-Danko, Peter Balogh
Dátum:	2024
Megjegyzések:	Due to hyperprolificacy in modern pig production, nurse sows are used to nurse surplus piglets. Additional stay in lactation results in loosing back fat thickness which is associated with poor reproductive performance. Therefore, the aim of this research was to characterize and quantify causes of Reproductive Failure (RF) removal and the risk of removal associated with parity. Archived reproductive data was retrieved from a large company database between 2016-2022. Records of 37852 nurse sows culled due to reproductive failure before reaching their next parity were analyzed using SPSS statistics software and Chi-square test used to test between the group differences. The major RF causes were; failure to conceive 30.7%, no heat 23.0% vaginal discharges 19.3%, abortion 11.4%, failed to farrow 8.0% and retained pigs 7.5%.The risk of removal due to fail to conceive was significant (?2=352.480, P<0.001was detected for abortion among parities. RF is an unplanned sow removal reason that requires decision making in an attempt to control it. Understanding the risk associated with each cause of RF removal could help producers plan how to decide on selecting a nurse sows.
