The present study was designed to investigate the impact of in-ovo injection folic acid and glucose on hatching eggs from 55 weeks old broiler breeders. A total number 900 were collected Arbor Acres breeders, then, divided into 6 groups including 1) Negative Control (non-injected, NC), 2) Dry Punch (pricked without injecting any solution, DPC), 3) Positive (eggs injected with 0.5 mL normal saline, PC), 4) Folic Acid group 0.2 mg/ egg acid, FA), 5) Glucose 125 glucose, Glu), 6) mg FA+Glu)....
This study aimed to explore how different genotypes influence eggshell traits, egg quality, ultrastructure and nutritional value in quails during the production phase. Two breeder lines selected for six generations, brown quail white quail, were subject analysis, with 90 eggs examined each genotype. At 42 days of age, 180 used, from strain characteristics shell microstructure. The results indicated that breed had a significant effect on various parameters, including weight, length, width,...
