A retrospective investigation of farrowing performance was conducted in a 600 sow herd that added new facilities (18 crates) and renovated old facilities (72 crates) over a period of approximately 2 years. PigChamp records were used to retrieve data including livebirths/litter (LB), stillbirths/litter (SB), mortality/litter (MORT) and litter weaning weights (WW; adjusted to a 21 day lactation). Crate types included hydraulic, bowed bar and finger configurations. Floor types included all bare wire with a mat (WIRE) and bare wire under the sow with plastic coated wire in the creep areas (COMB). Floor type, regardless of crate type, had the greatest impact on performance, especially WW. Weaning weights were significantly greater for COMB compared to WIRE. MORT and SB rates were less in COMB compared to WIRE. The bowed bar crates tended to have poorer performance compared to the other crate types. These data suggest that floor type significantly impacts farrowing barn performance and that crate type has less impact. (Download PDF)    (Export to EndNotes)
