Abstract

This study including the effect of chickens embryos injection with
nutritional fluids and early feeding ( at hatchery) to improve productive and
physiological traits of broiler chickens . using seven hundred Hubbard fertely
eggs divided in to equal 7 treatmants were injected on day 18 of incubation
with 0.5 ml, 1.5% concentration of different compounds into ear sac as
follows .
Glucose (treatment 1) ascorbic acid (treatment 2), lysine (treatment 3)
methionine (treatment 4), mixture (treatment 5) sterile distilled water alone
(treatment 6) and negative control without injection (treatment 7). Eggs
carried back to incubation. Hatching chicks of each treatment were divided
into two groups. Chicks of first group were fed starter diet at hatchery (early
feeding), whereas second group was fed after (12 hours) at poultry farm. All
birds were reared till 8 weeks at the Poultry Farm for Research.
Results obtained can be summarized as follows:
1-A significant (P < 0.05) increase in chick final weight .
2-A significant inprovement in feed conversion ratio also dressing percentage
in injected treatments.
3- Injected treatments exhibited a significant (P < 0.05) increase in
hemoglobin concentration.
4- Early feeding (at hatchering) has surpassed feeding at poultry farm with
respect to productive and physiological traits.
