Effect of space allowance and mixing on growth performance and body lesions of grower-finisher pigs in pens with a single wet-dry feeder

Table 1 Initial and final space allowance coefficient (k) for each treatment in experiment 1 and 2

	Experiment 1			Experiment 2
Number of pigs/pen	10	12	14	10	13
Space allowance, m²/pig	0.96	0.84	0.72	0.96	0.78
Space allowance coefficient, k ^a
Initial ^b	0.110	0.095	0.079	0.090	0.074
Final	0.042	0.037	0.031	0.042	0.034

^a The allometric expression of the space coefficient is as follows: κ = Space allowance (m²) / BW^0.667 (kg)
^bInitial body weight in experiment 1 was: 25.6 ± 1.38 kg (0.96 m²/pig), 26.1 ± 1.38 kg (0.84 m²/pig) and 27.4 ± 1.38 kg (0.72 m²/pig). Initial body weight in experiment 2 was: 34.6 ± 0.95 kg (0.96 m²/pig) and 34.1 ± 0.95 kg (0.78 m²/pig)
