Effect of injected different concentrations of alcoholic extract of moringa oleifera leaves powder in hatching eggs of advanced age of broiler breeders on productive performance and carcasses of broiler chickens

Abstract EN

This experiment was conducted to study the effect of injecting hatching eggs into a flock of broiler aged mothers with different concentrations of the alcoholic extract of Moringa Oleifera powder on productive performance of broilers during the period of rearing of 35 days.

the study included two experiments for a period at 2 / 10 / 2021 to 28 / 11 / 2021, where eggs were injected into the Mustafa Poultry Hatchery / Wasit Governorate-Aziziyah district.

a 400 hatching eggs of 308 ross mothers of modern broilers used at age of 48 week, eggs of average weight 66 ± 1 G / egg were collected in same day then stored for two days.

a quarter of treatments were randomly distributed with 100 eggs for each treatment.

the first treatment T 1 without injection as control treatment, and T 4, T 3, and T 2 (while injected into the space air) on day 12 of, in an amount of 0.2 ML for each egg, with concentration of 450, 300, 150 MG / ML, respectively.

the hatched chicks were bred in the same fields, where 180 chicks of the chicks were distributed into four treatments, 45 chicks for each treated and three replicates (15 chicks) for each T 1, T 2, T 3 and T 4 were placed in a cage for 35 days.

the results showed a significant (P < 0.05) increase for T 4 compared to the control in body weight, body weight gain and relative weight of the gizzard, will all injection treatment recorded a highly significant decrease in the total feed consumption and feed conversion ratio compared to control treatment.

while there were no significant differences between treatments in the percentage of total mortality, relative weights of the heart, liver, breast and thighs and dressing ratio.
