Effect of Supplementary Methionine on Feather Growth and Related Indicators of Pigeon Squabs
ABSTRACT We assessed the effect of health sand dietary supplementation with methionine (Met) on White King pigeons. Paired pigeons (n = 180) were fed one of five diets; group T1 received no added Met, while T2, T3, T4 and T5 received 30, 60, 90 and 120 g of supplemental DL-Met/kg, respectively. Each...

| description | ABSTRACT We assessed the effect of health sand dietary supplementation with methionine (Met) on White King pigeons. Paired pigeons (n = 180) were fed one of five diets; group T1 received no added Met, while T2, T3, T4 and T5 received 30, 60, 90 and 120 g of supplemental DL-Met/kg, respectively. Each treatment was replicated three times with 24 pairs in each replicate. The results showed that supplementary Met had a minor effect on the length of the fourth primary wing feather in 28-day-old squabs (p>0.05), but the length of 14-day-old squabs in T2 was significantly longer (p=0.010). Dietary Met had a minor effect on Wnt-7a and fibroblast growth factor receptors-2 (FGFR-2) mRNA levels in 28-day-old squabs (p>0.05). The IGF-1 concentration in plasma was highest in T4 and lowest in T2 (p=0.012), but there was no difference between T1, T2 and T5 (p>0.05). In the chest muscle, the expression of IGF-1 in T3 and T4 was higher than in T1 (p=0.172 and 0.015, respectively). In the leg muscle, IGF-1 mRNA level was higher in T4 and T3, and lower in T2 (p>0.05). The results indicate that the optimal Met supplement for increasing fourth primary wing feather length was 30 g/kg Met in health sand, and the feathers were the longest in 14-day-old squabs. Adding 90 g/kg Met to health sand can improve the concentration of IGF-1, which is important for growth performance of pigeon squabs. |
