Piglets weaned at 28 days weighing 9.1 ± 1.1 kg | 1% for 14 days | Increased gross energy digestibility coefficient Tended to enhance dry matter, organic matter and neutral detergent fibre digestibility |
Furbeyre, et al. [75] |
Piglets, weaned at 28 days weighing 12.0 ± 0.89kg | 10% for 28 days | Increased total tract apparent digestibility of crude fat and acid detergent fibre (lysozyme supplementation) Decreased total tract apparent digestibility of crude protein (with or without lysozyme) |
Martins, et al. [80] |
9 week-old growing-finishing pigs weighing 22 ± 1.6 kg | 9.5% with amino acid supplementation, mostly lysine, for 35 to 49 days | Digestibility was not analysed | Altmann, et al. [40] |
Growing-finishing pigs weighing 60 kg | 13% with amino acid suplementation, mostly lysine. for 10 days | No significant effect on apparent nitrogen digestibility | Neumann, et al. [69] |
