Abstract:
This study was conducted to evaluate the effect of floor space allowance on productivity of sows. A total of 48 sows (Landrace × Yorkshire; 220.64 ± 5.18 kg average initial body weight) were randomly assigned to four treatments (floor space allowance of 1.9 m2, 2.1 m2, 2.3 m2, 2.5 m2). Diets were titrated or exceeded the nutrient requirements for sows recommended by Nutrient Requirements of Swine of National Research Council. All sows were moved to floor space allocation six weeks after artificial insemination and transferred to farrowing crates at 107 days of gestation. There were no differences in sow performance, reproductive performance of sows in treatments. However, the total solids (%) and protein (%) of colostrum composition of sows in 2.3 m2 was less than that of sows in 1.9 m2 (p & lt; 0.05). In conclusion, the floor space allowance of 1.9 ~ 2.5 m2 (0.2m2 intervals) did not show a difference in sow productivity, and colostrum composition showed a positive effect at 1.9 m2. An experiment to investigate sow productivity by applying a larger area than a space allowance of 2.5 m2 is necessary.
