Combinations of essential and non-essential amino acids (Lys+Arg, Lys+Met+Cys, Thr+Gly+Ser, Ile+Leu+Val and Gly+Pro) were injected into 50 eggs in each tr...

15 صفحه اولInfluence of In-ovo Arginine Feeding on Post-hatch Growth Performance and Economics of Broilers
A total of 420 fertile broiler eggs (Cobb) with uniform egg weight were collected and divided into three groups: non-injected control, injected control (0.5 ml of 0.9% normal saline) and arginine (0.5 ml of 0.5% arginine); and injected on 18 day (d) of incubation into amnion.
