Effects of dietary lysine concentration on the growth performance of broiler chickens during the 8-week period.
| Parameters | Dietary Lysine Concentration | SEM | p-Value | ||
|---|---|---|---|---|---|
| 75% | 100% | 125% | |||
| Initial body weight, g | 39 | 39 | 39 | 0.057 | p < 0.05 |
| 8-week body weight, g | 2002 c | 3513 b | 4180 a | 119.2 | p < 0.05 |
| 8-week body weight gain, g | 1983 c | 3493 b | 4147 a | 128.7 | p < 0.05 |
| Feed intake, g/8 weeks | 3860 c | 6277 b | 7132 a | 72.6 | p < 0.05 |
| 1 Feed conversion ratio | 1.98 a | 1.75 b | 1.63 b | 0.09 | p < 0.05 |
| Lysine consumption, g/8 weeks | 32.81 c | 71.56 b | 101.3 a | 19.83 | p < 0.05 |
| Percentage mortality | 21.43 a | 3.57 b | 2.91 b | - | p < 0.05 |
a,b,c Means with different superscript letters differ significantly at p < 0.05. 1 Feed conversion ratio was calculated by dividing the feed intake (g) by the body weight gain (g).
