Impact of growth curve and dietary energy-to-protein ratio of broiler breeders on egg quality and egg composition

Effect of different dietary energy/protein ratios on growth performance, reproductive performance of breeding pigeons and slaughter performance, meat quality of squabs in summer

“…In the present study, we found no significant effect of the interaction of CP and ME levels in breeding pigeon diets on egg quality, including mean egg weight, egg shape index, and yolk weight, among others. Similar studies have also observed in laying hens that dietary energy/protein ratios do not affect yolk weight, Haugh unit, or shell thickness ( Ding et al., 2016 ; Heijmans et al., 2022 ). Therefore, an appropriate level of energy/protein ratio in the diet will be more favorable to the best weight recovery of pigeons after the lactation period, thus optimizing reproductive efficiency could achieve sustainable pigeon farming.…”
