Autor: Satomi Tani, Carlos Piñeiro, Yuzo Koketsu

Publikováno v: Porcine Health Management, Vol 4, Iss 1, Pp 1-9 (2018)

Abstract Background The objectives of our study were 1) to characterize culling and retention patterns in parities 0 to 6 in served females and farrowed sows in two herd groups, and 2) to quantify the factors associated with by-parity culling risks f

Journal of Dairy Science, 2021, 104 (12), pp.12664-12678. ⟨10.3168/jds.2020-19974⟩

International audience; In the long term, resilient animals are able to maintain their normal biological processes when confronted with environmental perturbations, reducing their risk of being culled. Therefore, longevity can be proposed as an indic
